According to a 2017 article by Peters and colleagues, millions of students have already demonstrated they know the material slated to be taught that year. Consequently, grade-level standards are unlikely to be appropriately challenging for these students. In this paper, we conceptually replicated and extended this prior study. Using data from schools that administered the Renaissance Star assessment in Fall 2018 and Fall 2021, we quantified pre-COVID and mid-COVID average achievement and variance in achievement in mathematics and reading in fifth grade and estimated the grade level of instruction needed for students. Our results indicate that (a) achievement dropped during COVID-19 relative to pre-COVID, but the drop in mathematics was larger, and (b) achievement variability increased during COVID-19, but the variability in reading was slightly more pronounced. Further, our results replicated Peters et al.'s (2017) results showing that large numbers of students still performed above grade level, and substantial variability in achievement was present within schools.

Measuring meaning is a central problem in cultural sociology and word embeddings may offer powerful new tools to do so. But like any tool, they build on and exert theoretical assumptions. In this paper, I theorize the ways in which word embeddings model three core premises of a structural linguistic theory of meaning: that meaning is coherent, relational, and may be analyzed as a static system. In certain ways, word embeddings are vulnerable to the enduring critiques of these premises. In other ways, word embeddings offer novel solutions to these critiques. More broadly, formalizing the study of meaning with word embeddings offers theoretical opportunities to clarify core concepts and debates in cultural sociology, such as the coherence of meaning. Just as network analysis specified the once vague notion of social relations, formalizing meaning with embeddings can push us to specify and reimagine meaning itself.

We develop a novel application of machine learning and apply it to the interview transcripts from the American Voices Project (N = 1,396), using discourse atom topic modeling to explore social class variation in the centrality of family in adults' lives. We take a two-phase approach, first analyzing transcripts at the person level and then at the line level. Our findings suggest that family, as represented by talk, is more central in the lives of those without a college degree than among the college educated. However, the degree of institutional overlap between family and other key institutions -- health, work, religion, and criminal justice -- does not vary by education. We interpret these findings in the context of debates about the deinstitutionalization of family in the contemporary United States. This demonstrates the value of a new method for analyzing qualitative interview data at scale. We address ways to expand the use of this method to shed light on educational disparities.

Instructor leadership is widely recognized as essential for facilitating meaningful online learning in higher education. While previous studies have applied organizational leadership theories to the study of instructor leadership, fewer studies have investigated online instructor leadership. This predictive correlational study detailed the associations between the Community of Inquiry (CoI) framework and servant leadership (SL) theory and employed multiple regression analyses to investigate the predictive relationships of seven SL dimensions on the three CoI presences. Survey data were gathered from 148 graduate students enrolled in online courses in education, communication, and engineering master's degree programs using the CoI Survey (Arbaugh et al., 2008) and the SL-28 (Liden et al., 2008). The findings revealed a significant positive correlation between the instruments. The predictive model as a whole explained 66% of the variance in students' perceptions of a CoI. Three SL predictor variables demonstrated the most influence: helping subordinates grow and succeed, conceptual skills, and creating value for the community. Additional analyses at the CoI subscale level revealed that the SL variables accounted for 73% of the variance in teaching presence, 55% of the variance in cognitive presence, and 31% of the variance in social presence. Implications and limitations are discussed and recommendations are proposed to implement online instructor SL.

Higher education institutions continue to invest in online learning, yet research indicates instructors often lack experience, preparation, and guidance for teaching online. While instructor leadership is essential for meaningful online learning, few studies have investigated online instructors' leadership behaviors. This study offers new insights into the conceptual and empirical alignment between instructor leadership, as interpreted through the dual lenses of organizational leadership theory and the Community of Inquiry (CoI) framework, proposing instructor leadership as foundational to the teaching and learning experience in a CoI. Specifically, the convergent mixed methods study investigated students' (N = 87) and instructors' (N = 7) perceptions of instructor servant leadership (SL) behaviors in an online graduate-level course designed to facilitate a CoI. Results demonstrate instructor SL behaviors were perceived differently by students and instructors, instructors' self-perceptions were generally higher than students' perceptions, and students' perceptions of instructor SL were positively correlated with their satisfaction with the course and instructor. Implications offer insights into instructor leadership behaviors important for developing instructor leadership presence to facilitate meaningful learning and student satisfaction in higher education online learning.

In this quantitative comparative study, we explored the differences in technology integration self-efficacy, use of self-regulated learning strategies, and actual learning between preservice teachers enrolled in blended sections (n = 275) and online sections (n = 50) of the same introductory educational technology course. The results revealed that preservice teachers enrolled in the online format of the course reported a significantly higher level of using time management strategies, but a significantly lower level of employing help-seeking strategies compared to preservice teachers enrolled in the blended format of the course. However, no significant differences in technology integration self-efficacy and actual learning existed. Results offer insight for designing educational technology courses that align with the needs of both online and blended learners and preparing preservice teachers that likely will be responsible for facilitating blended and online learning with their own students.

Considering preservice teachers' reflections on their best academic learning experiences, the purpose of this research was to use a problem-solving lens to analyze how preservice teachers were first identifying an educational problem and then suggesting solutions where educational technology could be meaningfully implemented. This research used an exploratory, descriptive qualitative method. The participants included 100 preservice teachers enrolled in an introductory educational technology course at a large midwestern university in the U.S. Data were analyzed using an ill-structured problem-solving model synthesized from previous literature, with results presented by key phases: identifying problems, generating solutions, making justifications, and monitoring. The results of this study indicate that preservice teachers (i.e., novice problem solvers) had a simplistic understanding of technology integration, likely resulting from underdeveloped problem-solving skills. These results provide insight into the preservice teachers' problem-solving thinking and how they conceptualized the teaching-learning process, including technology integration.

Primary and secondary education systems experienced substantial disruption during the COVID-19 pandemic. However, little is known about how public health policy has affected Australian teachers during the pandemic. This study examines teacher perspectives on a sudden change of policy, whereby schools were abruptly opened to students at the beginning of the pandemic. At the same time, strict social distancing rules applied to the remainder of the population. Qualitative data from 372 Western Australian schoolteachers were analysed using thematic analysis. Results highlight substantial impacts on teachers' workloads and adverse effects on wellbeing. Perceptions that they were acting as guinea pigs and subjected to different social distancing rules than other citizens were particular stressors. Findings highlight substantial consequences of public health policies on the roles and wellbeing of teachers.

Discussion is an essential component in case-based learning (CBL), as it offers students the opportunity to consider diverse perspectives, clarify confusion, and construct understanding. As a facilitator bears most of the responsibility for the overall success of CBL, understanding how facilitation strategies influence interactions during discussions is worthwhile. However, previous CBL facilitation research has primarily considered student perspectives during case discussions, without examining relationships between facilitator experience and student interaction and participation. This study combined social network analysis and content analysis to compare the structure of expert and novice instructors' discussion posts and to consider their relationship to student participation and interaction in online case discussions. Results showed that both the expert and novice instructors used facilitation strategies involving social congruence, cognitive congruence, and content expertise frequently in the discussions; however, when and how they used a combination of these strategies was noticeably different. These differences influenced student interaction. More specifically, students tended to interact with others more actively and densely as a result of questions initiated by the expert facilitator. Suggestions are provided for novice facilitators.

Background: Faculty in nursing and history at Creighton University directed two service-learning courses on the history and public health implications of lead (Pb) exposure in Omaha, NE. As part of their service requirements, students conducted or observed blood lead screenings in area schools and reflected on these shared experiences in discipline-specific coursework. Strong student response encouraged the faculty to enrich transdisciplinary teaching and learning between these two courses. Although studies supply numerous best practices to develop collaborative experiences and service-oriented pedagogies, little work focuses on enriching collaborations between preexisting courses. Purpose: This study examines the outcomes of a partnership between nursing and history and presents a practical model that instructors can use to foster and deepen transdisciplinary service-learning. Methodology: Employing a hybrid grounded theory/topic modeling analysis of student reflection papers, we identify course outcomes of closest convergence. Findings/Conclusions: We argue that instructors can deepen transdisciplinary partnerships between service-learning courses by focusing on a common exemplar, encouraging collaborative experiences in the classroom and at service sites, and employing civic health as a shared concept in curricula. Implications: Beyond nursing and history, our model may be employed by faculty in preexisting service-learning courses to bring their courses into transdisciplinary convergence.

Case-based instruction (CBI) provides a way to vicariously engage preservice teachers in their future teaching realities. However, little research has considered how different discussion facilitation strategies relate to the development of preservice teachers' instructional design (ID) skills. We used an embedded mixed methods case study research design to compare differences in how preservice teachers approached the ID process when engaged in one of two strategies: discussions guided by pre-constructed prompts and a facilitator and discussions guided by pre-constructed prompts only. Findings revealed that preservice teachers who participated in discussions guided by a facilitator analyzed case problems more deeply, as they identified more sources of inspiration to guide their design choices; considered learner, environmental, and content characteristics more often; and reported spending more time understanding case problems. While most preservice teachers believed they could apply what they learned from participating in CBI to their future profession, preservice teachers receiving prompts only were more positive about the discussion aspect of CBI.

Educators consider the development of problem-solving skills in learners to be a primary goal of contemporary teaching and learning efforts. Yet, participating in problem-centered instruction is challenging for learners, and educators have sought different ways of supporting learners as they make sense of complex content. Social media applications are readily available for use by educators, which in turn provides many opportunities for these tools to support teaching and learning activities. While social media affordances offer educators exciting opportunities to support learners in authentic problem-solving contexts, these tools do not come without challenges, and little research has considered how such tools can specifically facilitate the development of learners' problem-solving abilities. The purpose of this paper is to identify prominent educational affordances of social media and to explore how these identified affordances have the potential to support ill-structured problem-solving activities. This paper offers researchers and educators new directions for facilitating problem-centered learning when using social media.

Estimates show that one in six children aged three through 17 in the United States have one or more developmental disabilities. Many early childhood education programs aim to improve early identification of children with developmental disabilities and increase family engagement, specifically Head Start and Early Head Start programs. The present study employed a convergent, parallel mixed-method research design to evaluate the integration of the Centers for Disease Control and Prevention "Learn the Signs. Act Early" materials into Early Head Start settings and examine how the use of the materials in the classroom setting influenced the relationship and engagement between caregivers and staff. The quantitative strand of the study employed descriptive statistics to interpret survey data and the qualitative strand of the study used a template approach to analysis for the analysis of focus groups and semi-structured interviews. Participants reported that the materials supported caregiver and staff communication and served as a catalyst for staff to build a deeper rapport with the families. The materials provided a consistent language for parents and staff to use to discuss developmental milestones and helped bridge gaps in communication that were previously present due to differing levels of understanding regarding child development. Additionally, the caregiver engagement with developmental monitoring increased and they were able to track milestones of their respective children alongside Early Head Start staff. Data show there is value in the use of the materials due to the positive affect they have on caregiver and staff relationship and engagement.

Asynchronous discussions are typically considered an essential aspect of online case-based learning. While instructors implement discussions to support a variety of instructional purposes during case-based learning (e.g., facilitate students' sense making, prompt the consideration of diverse perspectives, debate complex topics), whether students receive the expected benefits is unclear, and little research has considered how students intentionally participate in discussions to support their learning during case-based learning. At the same time, students' participation in asynchronous online discussions represents a complex endeavor. That is, students must make several decisions regarding how to effectively participate, while simultaneously experiencing several challenges. The purpose of this exploratory multiple-case study was to consider the experiences of six graduate students participating in asynchronous online discussions as a part of a case-based course. By analyzing these experiences, we were able to conceptualize students' navigation of an asynchronous online discussion as a problem-solving process and consider individual problem-solving approaches. Results indicate that students relied primarily on instructors to determine the purpose of their discussion participation, expressed differing levels of value for participating in discussions, adopted a variety of strategies to meet discussion participation goals, and assessed their participation efforts mainly based on guidelines set by the instructor. We offer suggestions for effectively designing and facilitating asynchronous online discussions and discuss areas needing future research.

Using a mixed methods design, this study examines graduate students' perceptions of attitudinal learning regarding the use of case-based learning (CBL) methods in an online instructional design course. One hundred and thirty-three students completed a survey taken from the Attitudinal Learning Inventory (ALI) in weeks three and seven of the eight-week course. Using Latent Profile Analysis (LPA), three classes of student types were identified: Skeptics who perceived low and declining attitudinal learning throughout the course, Adopters who perceived high and rising, and Advocates, who perceived very high and rising attitudes. Student reflection assignments on developing instructional design expertise using CBL, and a post-course questionnaire sent out five months after the course concluded were analyzed to gain further insights into student experiences and perspectives of both the course and CBL. Results indicated the majority of students perceived positive attitudinal learning throughout the course and had positive views of CBL as an instructional method. Students who struggled had less prior ID experience and seemed to exhibit a more negative perspective towards the course and CBL despite reporting less external challenges that impacted their learning in the course than the positive groups. Implications highlight the importance of facilitating SRL development and supplementing more novice CBL and ID students with additional support.

Nontraditional students seeking a teaching license are tasked with managing coursework and other responsibilities associated with teacher preparation programs; however, they are also likely navigating family dynamics, financial struggles, and other obligations that traditional undergraduate students do not face. We interviewed 19 preservice teacher candidates and report on their experiences when selecting their university of choice, the barriers they faced, and the supports they received. Participants reported coming to their university because of cost, location, and reputation. They reported common barriers such as inability to work, caring for children, and lack of support or access to other resources. However, participants reported professors and external funding as the major factors that had helped them succeed. Implications about this diverse group of students are discussed.

Public culture is a powerful source of cognitive socialization; for example, media language is full of meanings about body weight. Yet it remains unclear how individuals process meanings in public culture. We suggest that schema learning is a core mechanism by which public culture becomes personal culture. We propose that a burgeoning approach in computational text analysis -- neural word embeddings -- can be interpreted as a formal model for cultural learning. Embeddings allow us to empirically model schema learning and activation from natural language data. We illustrate our approach by extracting four lower-order schemas from news articles: the gender, moral, health, and class meanings of body weight. Using these lower-order schemas we quantify how words about body weight "fill in the blanks" about gender, morality, health, and class. Our findings reinforce ongoing concerns that machine-learning models (e.g., of natural language) can encode and reproduce harmful human biases.

Reliably diagnosing autism spectrum disorders (ASD) in adulthood poses a challenge to clinicians due to the absence of specific diagnostic markers. This study investigated the potential of interpersonal synchrony (IPS), which has been found to be reduced in ASD, to augment the diagnostic process. IPS was objectively assessed in videos of diagnostic interviews in a representative referral population from two specialized autism outpatient clinics. In contrast to the current screening tools that could not reliably differentiate, we found a significant reduction of IPS in interactions with individuals later diagnosed with ASD (n = 16) as opposed to those not receiving a diagnosis (n = 23). While these findings need to be validated in larger samples, they nevertheless underline the potential of digitally-enhanced diagnostic processes for ASD.

Asynchronous online discussions (AODs) are a central component of online courses and have been widely implemented in case-based instruction (CBI). In online CBI, AODs offer learners a medium for making sense of complex problems, as they consider case topics collaboratively with peers and facilitators. Therefore, learners' interactions with others have the potential to impact the overall effectiveness of the method, and specifically, participating in AODS during CBI may help learners develop problem-solving skills. However, little research has considered how learners' interaction patterns in an AOD relate to the development of problem-solving skills during CBI. We used social network analysis (SNA) to consider the relationship between social interactions and learners' problem-solving skills, as it offers a way to consider the structure of learners' social interactions. We found that the number of posts, replies, and connections learners made in course discussions were related to problem-solving performance measured both in case analyses and overall course grade.

The purpose of the study reported in this article was to investigate the contribution of engaging in an online Teacher Professional Development (oTPD) course to improving different facets of English as Foreign Language (EFL) teachers' Professional Development (PD). To this end, ten EFL teachers of a language institute participated in the study to be taught via Telegram mobile app (as a common Mobile Social Network Site (MSNS) in Iran) during a six-month teacher training project. A 35-item technology-enhanced TPD checklist consisting of several main sections incorporating demographic items, background information, and different issues regarding TPD was designed to measure EFL teachers' self-report TPD scores at the outset and end of the training course. Results pointed to the positive effects of oTPD course on participants' PD across different facets. The obtained findings have some implications for teacher educators, syllabus designers and practitioners in EFL contexts to have a fresh look at the complicated construct of PD including several facets, consider using MSNSs in teacher education and TPD courses, prepare online teacher education courses based on teachers' needs and opinions and provide teachers with follow-up support by devoting an elapsed time between teachers' participation in oTPD and application of their learning in the course.

Understanding theory is essential to instructional design (ID) research and practice; however, novice designers struggle to make sense of instructional design theory due to its abstract and complex nature, the inconsistent use of theoretical terms and concepts within literature, and the dissociation of theory from practice. While these challenges are generally understood, little is known about the sensemaking process of learners as they encounter these challenges in pursuit of deeper theoretical understanding. Using a collaborative autoethnographic approach, six ID learners investigated their sensemaking experience within an advanced ID theory course. Autoethnography, a form of qualitative research, focuses on self-reflection "to gain an understanding of society through the unique sense of self" (Chang et al., 2013, p. 18). Collaborative autoethnography, a type of autoethnography, explores anecdotal and personal experiences "collectively and cooperatively within a team of researchers" (p. 21). Using individual and collective reflexive and analytic activities, this inquiry illuminates the numerous sensemaking approaches ID learners commonly used to move beyond their initial, basic theoretical understanding, including deconstructing theory, distinguishing terminology, integrating concepts with previous knowledge, and maintaining an openness to multiple perspectives. Additionally, ID learners experienced significant struggles in this process but viewed these struggles as significant and motivating elements of their sensemaking process. Finally, this study offers implications for learners, instructors, and course designers.

Interest in the study of scale has grown over the past three decades, yet it still suffers from a lack of conceptual clarity. Despite attempts at conceptualizing scale, there is still wide diversity in how the term "scale" is used. These differences matter. They impact how scale is studied, the strategies used to achieve scale, and the lessons we can draw across studies of the scale of innovations. In this article, we argue that scale is a polysemic and dynamic phenomenon. There are multiple, legitimate definitions of scale, and such definitions can shift over time, depending on the goals and needs of reformers. Drawing upon an extensive review of the literature, we present a typology of scale comprising four predominant conceptualizations in the literature. We detail the conceptualizations and discuss the affordances and challenges of each. We conclude by offering implications of the polysemic, dynamic nature of scale for researchers and reformers. Presenting this typology, we aim to spark new conversations about scale and to help guide future scale research and practice.

Science is a core curricular area of instruction for all students and the federal mandates of the Individuals with Disabilities Education Act (2004) and No Child Left Behind (2001) require that students with disabilities are educated in the least restrictive environment and have access to general education science content, based upon rigorous standards. While, most students with visual impairments are educated in the general science classroom, few studies have been done to determine whether appropriate accommodations and modifications are being made in those classrooms to meet the specialized needs of these students. A 35 question survey instrument was disseminated to teachers of the visually impaired through a Visual Impairments Listserve and Facebook group to help determine what pedagogical practices, accommodations, modifications, adaptive equipment and instructional practices are being used to educate students with visual impairments in the United States and Canada. This study helped inform how students with visual impairments are being educated in the science classroom.

TeachersPayTeachers.com (TpT) has emerged as an alternative to traditional curricular publishing houses; however, the critical investigation into this for-profit platform is limited. The aggregate content offered and downloaded from the platform through 2019 was Web-scraped, enabling us to construct a content model of TpT and provide descriptive results regarding the interactions between content, technology, and users/usage on TpT. We find TpT's content model implicitly redefines what constitutes an education, elevating holiday activities and classroom decor to the same level as established curriculum. In terms of content, learning standards were largely absent and user ratings were uniformly high, casting doubt upon the validity of these technological features. 87.9% of resources were under $5, however, many small sales add up across users, indicating the platform extracts significant value from educators and schools. We discuss how the online educational marketplace phenomenon stands to impact the future of curriculum production and the teaching profession.

Introduction: Braille literacy for students who are visually impaired (i.e., those who are blind or have low vision) can be a critical component for school and postsecondary transition success. This survey study was a modified replication of previous studies that examined the instruction of literary braille in university preparation programs for professionals who work with students with visual impairments. Methods: Nineteen university instructors of literary braille responded to a survey about instructional formats, books, and tools, as well as assessment issues, such as test formats, scoring, and requirements for demonstrating proficiency. Results: Survey responses indicated that some instructional strategies at the university level have remained the same over the last 20 years, but there are also some changes. Most notably, updated books and resources are being used and instructors represent the same demographic group, Caucasian females over 45 years old. But, the level of experience has substantially dropped and there has been a shift to increased online learning. All programs indicated focusing instruction on Unified English Braille (UEB) code. Discussion: Prior concerns about the challenges of teaching UEB have been somewhat satisfied. Proficiency exams are now required by programs, which could contribute to better prepare teachers for students with visual impairments. Implications for Practitioners: The shift to online learning affects practice. The use of braille simulation software might alter the way practitioners think about erasures. In preparing for distance learning, instructors must consider how to make courses accessible, rigorous, and of high quality. Although university braille proficiency exams should continue to be used to evaluate the skills of future professionals, educators might advocate for tests at the state or province level prior to licensure and common standards for minimal competency.

Nearly eight million "non-traditional" students face adversity beyond financial instability, childcare, or full or part-time work when seeking teacher licensure. They must manage logging clinical hours in schools far from home, feel isolated in cohorts of 18-20-year-olds, and sometimes lack support and flexibility from their professors and advisors. We surveyed non-traditional, undergraduate, teacher licensure candidates at a large midwestern university to better understand current attending students' demographics and determine if any relationship(s) existed between variables related to logistical decisions, supports received, or barriers faced/encountered. We summarized findings from 53 participants and offered suggestions to university administrators, professors, and staff to support the growing population of non-traditional teacher candidates.

"Online learning"--learning that involves interactions that are mediated through using digital, typically internet-based, technology--is pervasive, multi-faceted, and evolving, creating opportunities and challenges for educational research in the wake of the COVID-19 pandemic. In this special issue, we advance an interdisciplinary agenda for online learning research at the intersection of educational technology, educational psychology, and the learning sciences. In this first article in the issue, we define online learning including its variants, review historical and current contexts, explore its multidimensionality, and assert key issues shaping contemporary online learning. We propose five important lenses: "community," "engagement," "pedagogy," "equity," and "design-based research," through which scholarly communities are creating knowledge that influences research and practice in online learning contexts. These lenses highlight points of conceptual overlap between the online and psychological learning literatures. The special issue is organized around these lenses and includes an article representing each one, complemented by commentaries that offer critical appraisal and synthesis.

Background: Undetected ear and hearing problems negatively impact the quality of life of people with intellectual disability. Methods: This multicentre retrospective study describes the outcome of 10 years of ear and hearing screening in athletes with intellectual disability in seven European countries. The screening was conducted by a trained team using a strictly standardised protocol. Results: Of 15,363 screened athletes with intellectual disability, more than half (58.7%) needed referral for ear and/or hearing problems, ranging from 51.7% (<20 years old) to 81.4% ([greater than or equal to] 60 years old). The most commonly detected conditions were excessive/impacted earwax (40.3%), middle ear problems (30.1%) and hearing loss (27.0%), with significant differences between age groups and countries. Discussion: This study demonstrates an increased risk of ear and hearing problems in people with intellectual disability as compared to the general population. Considering the unawareness and impact of these problems, it is highly recommended to organise systematic screening. Follow-up for diagnostic elaboration, therapeutic management and long-term guidance should be provided.

Although using specific guidelines to structure course participation in online courses can boost learner engagement, research suggests that learners' overreliance on these standards can lead to superficial participation. As a result, alternative methods for participation assessment, such as ungrading or self-assessment, are increasingly being explored. Using a self-regulated learning lens, this ethnographic case study investigated how graduate students navigated participation self-assessment in an online advanced instructional design (ID) theory course. Results suggest that participation represented a unique construct across learners who did not always embrace technology affordances to support their learning and struggled to lead the monitoring process for their participation. Additionally, learners created goals that were incomplete and did not demonstrate an explicit awareness of the connections between course participation and learning. Implications for creating an effective ungraded approach for course participation in online settings are discussed.

Each year, over 450, 000 Lyme disease diagnoses are estimated to occur in the United States, and current preventive measures have been insufficient to stem the rising incidence. An effective human Lyme disease vaccine could be a powerful intervention for population-level impact. In advance of new Lyme disease vaccines coming to market, this study explored barriers to acceptability and motivations for the uptake of a new Lyme disease vaccine. Researchers conducted 9 online focus groups among consumers who may potentially benefit from the vaccine and 30 in-depth interviews among clinician groups who may provide the vaccine. All participants were recruited from three US regions of high Lyme disease incidence. Researchers found that participants shared common motivators to either recommend (clinicians) or accept (consumers) a Lyme disease vaccine, largely driven by perceived benefits of the vaccine, the lack of current effective preventive measures and a greater peace of mind. The concern about the challenges associated with diagnosing and treating Lyme disease is a primary motivator for clinicians to recommend the vaccine, while the concern about getting Lyme disease is a primary motivator for consumers to desire the vaccine.

This article presents the results of a study on the use of 3-D printed models in a science classroom for students with visual impairments and examines whether the use of these models impacts student conceptual understanding and misconceptions related to geosciences concepts, specifically plate tectonics. Data were collected one week prior to instruction, one week after instruction and throughout the 3-week instructional period. Results showed that students with visual impairments held many of the same misconceptions about plate tectonics as students who are typically sighted. All students in this study had fewer misconceptions after the instructional period than they held before instruction began; however, both the 3D group and the TG group continued to hold approximately equal numbers of misconceptions. The adaptations and hands-on experiences in this 3-week curriculum proved effective for students with visual impairments; helping them understand the unifying theory of plate tectonics. Some unique misconceptions held by the students with visual impairments in this research study include plates floating on the ocean, earthquakes moving with the plates, and volcanoes working together with the plates to cause earthquakes. There was a difference between students who had low vision and those with light perception only. The study helps to shed light on the use of 3-D printed models in the science classroom and their effectiveness at helping students with visual impairments learn important geoscience concepts.

As online learning continues to grow significantly, various efforts have been explored and implemented in order to improve the instructional experiences of students. Specifically, research indicates that how an instructor establishes his or her presence in an online environment can have important implications for the students' overall learning experience. While instructor presence appears to be an important aspect of online learning, more research is needed to fully understand this construct. The purpose of this study was to consider online instructors' perceptions related to presence, beliefs about actions, and the perceived impact of instructional presence. Using an explanatory multiple-case study approach, this research considered the perspectives of 13 instructors teaching in an online master's program at a large Midwestern public university. Results indicate instructors viewed instructor presence as an important component in online courses but their reasons varied. Furthermore, the instructors discussed a number of communication strategies they used, the importance of using such strategies to connect to students, and the potential impact of these strategies on student participation and learning. Additional themes from the interview data are discussed, and implications for online teaching and learning are suggested.

Objective: Given the number of college students with a normal BMI decreases 9-12% throughout the college experience, we wanted to model the traits responsible for behaviors impacting body composition in college-age women. Participants: Participants (n = 141) were recruited from a freshman-level nutrition course between August 2016 and May 2018. Methods: We built a path analysis model using variables from online questionnaires and lab visits. We grouped participants by median split of aerobic fitness and evaluated model fit. We defined statistical significance as p < 0.05. Results: The model provided an adequate representation of the data (CFI = 0.921). Aerobic fitness was the strongest predictor of body fat (p < 0.001) in both high-fit (-0.440) and low-fit (-0.469) women. Body dissatisfaction demonstrated relationships with body fat previously established in athletes and clinical populations. Conclusion: Physical activity to improve aerobic fitness appears most effective at maintaining healthy body composition in this population.

To date, little is known regarding how to best design instruction/guidance prompts that support learners' participation in collaborative argumentation (CA). To address this gap, this study compared the influence of two instruction/guidance prompts prior to learners' CA: problem representation (executive summary of the problem) and full problem-solving (problem representation, alternatives, justification, evaluation). Discussions were analysed using Phases 1-5 of the interaction analysis model (IAM) to determine the degree to which learners engaged in CA. Those in the full problem-solving condition were more likely to challenge the assertions of their peers. However, participants in the problem representation condition were more likely to integrate feedback as interaction progressed. This research describes how the design of instruction/guidance prompts affects the degree to which concepts and solutions are fixed as learners encounter differing perspectives from their peers during collaborative argumentation.

The Next Generation Science Standards (NGSS) chat (#NGSSchat) is a social media-based professional network used to discuss topics related to the NGSS in the United States. While successful reforms involve and coordinate the work of multiple stakeholders, recent research points out a striking lack of coordination between the individuals working in different educational roles--to the detriment of intended changes in the system. In this study, we analyzed more than 7,000 posts from individuals participating in #NGSSchat on Twitter (n = 247) during 2 years of 1-hr synchronous discussions. We studied the depth and types of conversations that took place, the extent to which the involvement of teachers, administrators, researchers, and organizations was balanced, and what explains participation in the network over time. Using a mixed-methods approach involving social network analysis, we found that conversations were primarily transactional, or social, and substantive, or providing opportunities for sense-making about the standards or for participants to transform their practice and that individuals from diverse roles participated, with teachers comprising the plurality of those involved. Additionally, researchers, administrators, and teachers were the most active in the network, with no differences in both initiating, or sending, and being the recipients of, or receiving, replies as a part of conversations. Finally, we found that being a teacher or administrator, as well as receiving replies from individuals who were important in the network, were positively related to sustained involvement in the network in the following year. We discuss how #NGSSchat--as a social media-based professional network--demonstrates similar features in other effective networks, and how social media-based networks invite new visions for how to implement ambitious, large-scale changes in science education.

The purpose of this study was three-fold: first, it aimed to develop a scale to shed light on English as Foreign Language (EFL) teachers' perceptions of using Mobile Social Network Sites (MSNSs) in language teaching and learning. To this end, a 36-item MSNSs Utility Perceptions Inventory (MUPI) was developed. Second, the current study made an attempt to investigate the construct validity and reliability of the MUPI through collecting data from 184 Iranian EFL teachers. The factorability of the data has been substantiated by running Kaiser-Meyer-Olkin test of Sampling Adequacy (KMO) and Bartlett's Test of Sphericity. The results of Exploratory Factor Analysis (EFA) revealed a three-factor solution for the inventory items. Furthermore, it was deemed that the scale had a high level of internal consistency. Third, this study strove to explore EFL teachers' perceptions of MSNSs use by analyzing the results of the administered scale. The findings showed that teachers put more emphasis on factor one (Advantages of MSNSs for Teaching and Learning) and factor three (Barriers to Using MSNSs for Teaching and Learning). The findings also indicated that approximately half of the teachers believed MSNSs allow them to have a more detailed, in depth conversation with their peers and colleagues in the course. Moreover, student distraction, insufficient Internet bandwidth/speed, and insufficient technical support for teachers were some barriers to using MSNSs in classrooms. It was also confirmed that developing communication skills, increasing communication, motivating students, and sharing feedback are some advantages of using MSNSs for teaching and learning. This study has some implications for EFL teachers, teacher educators, and syllabus designers to pay particular attention to the positive features of MSNSs and harness their pedagogical benefits in English language teaching and learning on the one hand, and teacher education courses on the other hand.

Twitter and other social media have assumed important places in many educators' professional lives by hosting spaces where new kinds of collegial interactions can occur. However, such spaces can also attract unwelcome Twitter traffic that complicates researchers' attempts to explore and understand educators' professional social media experiences. In this article, we define various kinds of spam that we have identified in our research on educators' uses of Twitter. After providing an overview of the concept of spam, we evaluate the advantages and disadvantages of different approaches to addressing the presence of spam in educator-focused Twitter spaces. Then we suggest practical, holistic metrics that can be employed to help identify spam. Through secondary analyses of our past research, we describe the use of such metrics to identify and deal with spam in three specific cases. Finally, we discuss implications of spam and these suggested methods for teacher educators, instructional designers and educational technology researchers.
