- Abstract
We report the results of a pre-registered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no two consecutive problems require the same strategy. Previous small-scale studies found that practice assignments with a greater proportion of interleaved practice produced higher test scores. In the present study, we assessed the efficacy and feasibility of interleaved practice in a naturalistic setting with a large, diverse sample. Each of 54 seventh-grade mathematics classes periodically completed interleaved or blocked assignments over a period of four months, and then both groups completed an interleaved review assignment. One month later, students took an unannounced test, and the interleaved group outscored the blocked group, 61% vs. 38%, d = 0.83. Teachers were able to implement the intervention without training, and they later expressed support for interleaved practice in an anonymous survey they completed before they knew the results of the study. Although important caveats remain, the results suggest that interleaved mathematics practice is effective and feasible.

- Abstract
High school freshmen in accelerated courses have known risk and resiliency factors that should be considered within systematic efforts to monitor and promote student academic and emotional well-being. This study created and evaluated a multi-method approach to identify students in Advanced Placement (AP) or International Baccalaureate (IB) courses with signs of risk mid-year in terms of stress, affective engagement, and academic performance. A total of 304 ninth grade students enrolled in AP/IB coursework and five AP/IB teachers at two public high schools in a Southeastern state took part in the screening. Using the researcher-developed screening approach, a total of 117 students (38.5%) met criteria for risk in at least one academic or emotional area. These results were compared to those obtained using a teacher nomination form, which had been developed collaboratively by the teachers and researchers, that specified signs of emotional and academic risk. The teacher nomination procedure resulted in the identification of 39.3% of the at-risk student population (average sensitivity rate = 35.7% across teachers). Sensitivity of teacher nominations was higher when identifying academic risk (average = 59.9%) as compared to emotional risk (average = 27.9% and 39.6% of students with low school satisfaction and high stress, respectively). Findings support the collection of data from students (surveys of stress and school satisfaction) and school records (course grades) when identifying AP/IB students to consider for targeted services within a multi-tiered system of supports.

- Abstract
This study explored how adaptive help seeking was related to academic self-efficacy, perfectionism (maladaptive and adaptive), attitudes towards help seeking (perceived benefits and perceived threats), and teacher emotional support among 311 grade 9 students in Advanced Placement and International Baccalaureate classes. Significant bivariate links emerged between adaptive help-seeking and all six potential correlates. Regression analyses indicated that teacher emotional support, adaptive perfectionism (high personal standards), and perceived benefits were significant, positive predictors of adaptive help seeking. Gender also was a significant predictor, as boys had lower levels of adaptive help seeking compared to girls. Furthermore, gender moderated the association between perceived benefits and adaptive help-seeking; perceived benefits were particularly highly associated with boys' adaptive help seeking from classroom teachers. Strategies for explicating the benefits of adaptive help seeking, promoting adaptive perfectionism, and fostering teacher emotional support are provided, as well as limitations and future directions for research.

Smith, Nicholas David W., Bradley-Klug, Kathy L., Suldo, Shannon M., Dedrick, Robert F., and Shaffer-Hudkins, Emily J.
- Abstract
Background: Conceptualizations of health have expanded to include indicators of adolescents' physical and mental wellness, rather than solely the absence of diseases or disorders. Although extensive research has identified links between mental and physical wellness, few studies have investigated the relationship between health promotion and happiness, particularly in adolescent populations who may be at particular risk for engaging in health-compromising behaviors, such as alcohol consumption. Methods: This cross-sectional study examined the relationship between 12 health-promoting behaviors and subjective well-being in a sample of 450 high school students from 2 states. Participants reported on their diet, physical activity, sleep hygiene habits, as well as abstinence from tobacco and alcohol products, and completed a multidimensional assessment of subjective well-being. Results: Findings demonstrated that 7 of the 12 health-promoting behaviors were significantly correlated with adolescents' subjective well-being. A sizeable portion of the variance in adolescents' subjective well-being (39.8%) was accounted for by the linear combination of the 12 health-promoting behaviors of interest. Increased physical activity, sleep hygiene cognitive/emotional factors, and bedtime routine all were identified as unique predictors of subjective well-being. Conclusions: These findings bring attention to the salience of daily physical activity and sleep hygiene and their associations with adolescents' happiness.

Suldo, Shannon M., Shaunessy-Dedrick, Elizabeth, Ferron, John, and Dedrick, Robert F.
- Abstract
Research has shown that students in Advanced Placement (AP) classes and International Baccalaureate (IB) programs experience higher levels of stress compared to students in general education classes. Elevated stress can serve as a risk factor for students' academic and mental health problems. Given the documented stress of these students, additional investigations are needed to more fully understand how students experience these curricula and the factors associated with positive student outcomes. Thus, we set out to identify factors associated with success among AP/IB students, with an emphasis on exploring potentially malleable factors that could be targeted with existing or newly developed interventions. Data were collected via self-report measures and school records from 2,379 students (Grades 9-12) enrolled in AP or IB in 20 school programs in one state. We examined the relationships among 34 predictors (e.g., stressors, coping styles, student engagement, family factors, school factors, and demographic features) of success. Success was represented by five outcomes in two domains: mental health (life satisfaction, psychopathology, school burnout) and academic (GPA, AP/IB exam scores). Better outcomes in both domains were associated with higher levels of achievement motivation and cognitive engagement, as well as lower levels of parent-child conflict, stress from major life events, and use of avoidance coping strategies. Higher levels of affective engagement, use of approach coping, and authoritative parenting were robust predictors of positive mental health outcomes and unrelated (in multivariate analyses) to academic outcomes. Findings have implications for subsequent development of intervention efforts targeting factors associated with student success.

Dedrick, Robert F., Shaunessy-Dedrick, Elizabeth, Suldo, Shannon M., and Ferron, John
- Abstract
In two studies (ns = 312 and 1149) with 9-12 grade students in pre-International Baccalaureate (IB) and IB Diploma programs, we evaluated the reliability, factor structure, measurement invariance, and criterion-related validity of the scores from the School Attitude Assessment Survey-Revised (SAAS-R; McCoach & Siegle, 2003a). Reliabilities of the five SAAS-R subscale scores were good (as > 0.80) for pre-IB (grades 9-10) and IB students (grades 11-12). Study 1 model fit indices for the five-factor SAAS-R model from confirmatory factor analyses showed greater misfit than those previously reported by McCoach and Siegle. In contrast, Study 2 fit indices for the five-factor model with pre-IB and IB students were similar to values reported by McCoach and Siegle. Tests of measurement invariance in Study 2 using multigroup confirmatory factor analysis identified three items within the Motivation/Self-Regulation subscale that differed in their item intercepts (i.e., uniform differential item functioning) with pre-IB students endorsing these items more strongly compared to IB students. Based on these results along with evidence of criterion-related validity as reflected in the moderate statistical relations between the SAAS-R subscales and students' GPAs, the SAAS-R shows promise as a research tool that can be used to examine the psychological factors associated with pre-IB and IB students' academic achievement.

Suldo, Shannon M., Dedrick, Robert F., Shaunessy-Dedrick, Elizabeth, Fefer, Sarah A., and Ferron, John
- Abstract
Successful coping with academic demands is important given the inverse relationship between stress and positive adjustment in adolescents. The Coping with Academic Demands Scale (CADS) is a new measure of coping appropriate for students pursuing advanced high school curricula, specifically Advanced Placement (AP) classes and the International Baccalaureate (IB) program. We developed the CADS in parallel with a new measure of stress designed for this same population (Suldo, Dedrick, Shaunessy-Dedrick, Roth, & Ferron, in press). We generated an initial item pool using multiple sources including focus groups and individual interviews with 177 students, 72 teachers, and 47 parents. Multiple iterations of expert review and item analyses resulted in 120 items, which were completed by 727 high school students in six schools (312 IB, 415 not in IB but taking at least one AP class). Exploratory factor analyses and additional item review indicated a 16-factor solution with 58 items. Cronbach's alpha reliabilities for the factors ranged from 0.53 to 0.90, with 11 factors exceeding 0.70. All 16 factors had test-retest reliabilities greater than 0.70. Support for the construct validity of the CADS scores was provided using a nomological network, which specified relationships between the CADS and broader dimensions of school-related coping dimensions (task, avoidance, and emotion-oriented), as well as indicators of achievement (GPA) and mental health (life satisfaction). An additional seven items that were not part of the 16-factor CADS, but which were identified as relevant in different phases of instrument development, are provided as a resource for researchers.

- Abstract
High school students in accelerated curricula face stressors beyond typical adolescent developmental challenges. The Student Rating of Environmental Stressors Scale (StRESS) is a self-report measure of environmental stressors appropriate for students in Advanced Placement (AP) and International Baccalaureate (IB) courses. We developed the StRESS in parallel with a new measure of coping designed for this same population (Suldo, Dedrick, Shaunessy-Dedrick, Fefer, & Ferron, in press). Items were derived from sentiments expressed during focus groups and individual interviews with 177 students, 72 parents, and 47 teachers. Multiple iterations of expert review and item analyses focusing on conceptual clarity and comprehensiveness resulted in 75 items reflecting stressors across domains, including school, home, and peers. High school students in AP or IB (N = 727) completed the 75-item inventory. Exploratory factor analyses and additional item review indicated a five-factor solution with 32 items. Cronbach alpha reliabilities ranged from 0.67 to 0.88. Five additional items representing a composite of Major Life Events also were included. The five factors and Major Life Events composite had test-retest reliabilities greater than 0.70. These scores were related to multiple conceptualizations of stress, as well as academic outcomes (GPA and attendance) and mental health (life satisfaction and anxiety), thus supporting the construct validity of the StRESS scores. Further support for the five-factor structure of the StRESS was provided by results of a confirmatory factor analysis (standardized root mean square residual = 0.051, root mean square error of approximation =0.048, comparative fit index = 0.900) with a separate sample of 2,193 AP and IB students.

12. Interleaved Practice Improves Mathematics Learning

Rohrer, Doug, Dedrick, Robert F., and Stershic, Sandra
- Abstract
A typical mathematics assignment consists primarily of practice problems requiring the strategy introduced in the immediately preceding lesson (e.g., a dozen problems that are solved by using the Pythagorean Theorem). This means that students know which strategy is needed to solve each problem before they read the problem. In an alternative approach known as "interleaved practice," problems from the course are rearranged so that a portion of each assignment includes different kinds of problems in an interleaved order. Interleaved practice requires students to choose a strategy on the basis of the problem itself, as they must do when they encounter a problem during a comprehensive examination or subsequent course. In the experiment reported here, 126 seventh-grade students received the same practice problems over a three-month period, but the problems were arranged so that skills were learned by interleaved practice or by the usual blocked approach. The practice phase concluded with a review session, followed 1 or 30 days later by an unannounced test. Compared to blocked practice, interleaved practice produced higher scores on both the immediate and delayed tests (Cohen's d = 0.42 and 0.79, respectively). Two appendices include: (1) Serial Position of Each Graph and Slope Problem in the Assignments (table); and (2) Frequency of Responses of Three Teachers to Statements About Interleaved Practice (table).

13. The Benefit of Interleaved Mathematics Practice Is Not Limited to Superficially Similar Kinds of Problems

Rohrer, Doug, Dedrick, Robert F., and Burgess, Kaleena
- Abstract
Most mathematics assignments consist of a group of problems requiring the same strategy. For example, a lesson on the quadratic formula is typically followed by a block of problems requiring students to use the quadratic formula, which means that students know the appropriate strategy before they read each problem. In an alternative approach, different kinds of problems appear in an interleaved order, which requires students to choose the strategy on the basis of the problem itself. In the classroom-based experiment reported here, grade seven students (n = 140) received blocked or interleaved practice over a nine-week period, followed two weeks later by an unannounced test. Mean test scores were greater for material learned by interleaved practice rather than by blocked practice (72% vs. 38%, d = 1.05). This interleaving effect was observed even though the different kinds of problems were superficially dissimilar from each other, whereas previous interleaved mathematics studies required students to learn nearly identical kinds of problems. We conclude that interleaving improves mathematics learning not only by improving discrimination between different kinds of problems but also by strengthening the association between each kind of problem and its corresponding strategy.

- Abstract
High school freshmen in accelerated courses have known risk and resiliency factors that should be considered within systematic efforts to monitor and promote student academic and emotional well-being. This study created and evaluated a multi-method approach to identify students in Advanced Placement (AP) or International Baccalaureate (IB) courses with signs of risk mid-year in terms of stress, affective engagement, and academic performance. A total of 304 ninth grade students enrolled in AP/IB coursework and five AP/IB teachers at two public high schools in a southeastern state took part in the screening. Using the researcher-developed screening approach, a total of 117 students (38.5%) met criteria for risk in at least one academic or emotional area. These results were compared to those obtained using a teacher nomination form, which had been developed collaboratively by the teachers and researchers, that specified signs of emotional and academic risk. The teacher nomination procedure resulted in the identification of 39.3% of the at-risk student population (average sensitivity rate = 35.7% across teachers). Sensitivity of teacher nominations was higher when identifying academic risk (average = 59.9%) as compared to emotional risk (average = 27.9% and 39.6% of students with low school satisfaction and high stress, respectively). Findings support the collection of data from students (surveys of stress and school satisfaction) and school records (course grades) when identifying AP/IB students to consider for targeted services within a Multi-Tiered System of Supports.

16. An Efficacy Study of Interleaved Mathematics Practice. Revised

Society for Research on Educational Effectiveness (SREE), Rohrer, Doug, Dedrick, Robert F., and Burgess, Kaleena
- Abstract
In a typical mathematics course, the material is divided into many lessons, and each lesson is followed by an assignment consisting of practice problems. Most commonly, each assignment consists solely of problems on the preceding lesson. For example, a lesson on ratios might be followed by an assignment with 12 problems on ratios. In other words, problems of the same kind are arranged in blocks. In this study, "blocked assignments" served as the control. In an alternative approach that is the intervention of interest, problems within the course are rearranged so that most of the problems within each assignment are based on previous lessons and arranged in an "interleaved" order. For example, after a lesson on ratios, an interleaved assignment might include a small block of four ratio problems and one problem from each of eight previous lessons. The remaining eight ratio problems are distributed across future assignments. Researchers conducted the study at a large public middle school in Tampa, Florida. Three middle school mathematics teachers and 140 of their seventh grade students participated. Students received 10 assignments over an 8-week period. All students received the same practice problems, but the problems were rearranged to produce two versions of each assignment. Across all assignments, students received 12 problems on each of four different kinds of problems. The study used a counterbalanced crossover design. For each assignment, researchers provided teachers with a slide presentation with solved examples and solutions to each problem. Teachers presented the examples before distributing the assignment. On the following school day, teachers presented the solutions while encouraging students to make any necessary corrections to their own solutions, and then collected the assignments. Within two days of each assignment's due date, at least one of the authors visited the school and scored the assignments. The Final Test was given to students during their regular classroom period and proctored by both the teacher and one author. Final test scores revealed that interleaved assignments were nearly twice as effective as blocked assignments. This finding suggests that interleaved mathematics assignments might be feasible and effective. This intervention could be implemented at all levels of mathematics instruction, and creators of mathematics texts and other instructional media can provide interleaved practice by simply rearranging practice problems.

- Abstract
High school students in accelerated curricula face stressors beyond typical adolescent developmental challenges. The Student Rating of Environmental Stressors Scale (StRESS) is a self-report measure of environmental stressors appropriate for students in Advanced Placement (AP) and International Baccalaureate (IB) courses. We developed the StRESS in parallel with a new measure of coping designed for this same population. Items were derived from sentiments expressed during focus groups and individual interviews with 177 students, 72 parents, and 47 teachers. Multiple iterations of expert review and item analyses focusing on conceptual clarity and comprehensiveness resulted in 75 items reflecting stressors across domains, including school, home, and peers. High school students in AP or IB (N = 727) completed the 75-item inventory. Exploratory factor analyses and additional item review indicated a five-factor solution with 32 items. Cronbach's alpha reliabilities ranged from 0.67 to 0.88. Five additional items representing a composite of Major Life Events also were included. The five factors and Major Life Events composite had test-retest reliabilities greater than 0.70. These scores were related to multiple conceptualizations of stress, as well as academic outcomes (GPA and attendance) and mental health (life satisfaction and anxiety), thus supporting the construct validity of the StRESS scores. Further support for the five-factor structure of the StRESS was provided by results of a confirmatory factor analysis (standardized root mean square residual = 0.051, root mean square error of approximation = 0.048, comparative fit index = 0.900) with a separate sample of 2,193 AP and IB students.

- Abstract
In two studies (ns = 312 and 1,149) with 9- to 12-grade students in pre-International Baccalaureate (IB) and IB Diploma programs, we evaluated the reliability, factor structure, measurement invariance, and criterion-related validity of the scores from the School Attitude Assessment Survey-Revised (SAAS-R). Reliabilities of the five SAAS-R subscale scores were good (as > 0.80) for pre-IB (Grades 9-10) and IB students (Grades 11-12). Study 1 model fit indices for the five-factor SAAS-R model from confirmatory factor analyses showed greater misfit than those previously reported by McCoach and Siegle. In contrast, Study 2 fit indices for the five-factor model with pre-IB and IB students were similar to values reported by McCoach and Siegle. Tests of measurement invariance in Study 2 using multigroup confirmatory factor analysis identified three items within the Motivation/Self-Regulation subscale that differed in their item intercepts (i.e., uniform differential item functioning) with pre-IB students endorsing these items more strongly compared with IB students. Based on these results along with evidence of criterion-related validity as reflected in the moderate statistical relations between the SAAS-R subscales and students' GPAs, the SAAS-R shows promise as a research tool that can be used to examine the psychological factors associated with pre-IB and IB students' academic achievement.

- Abstract
The purpose of this quantitative study, funded by the Florida Department of Education (FLDOE) through Just Read, Florida!, was to investigate the use of Tune in[TM] to Reading, an innovative reading intervention, with struggling adolescent readers in the juvenile justice system. One hundred and three students who exhibited issues ranging from behavioral problems to substance abuse and sexual offenses, from six residential sites, participated in this study. All participants were male with 52% African American, 31% Caucasian, and 13% Hispanic. Sixty percent of the students were in grades 8 and 9 and 44% of the students were identified as students with disabilities. At each site, students were randomized to the reading intervention, Tune in[TM] to Reading (TIR), or to a control condition (typically FCAT Explorer). A Cloze assessment was administered to students in both treatment and control groups before and after the nine week study period. Results across the six sites were mixed with TIR showing more positive effects, compared to the control in two schools, and similar effects compared to the control condition in four schools. Larger treatment effects (TIR) compared to the control condition, were observed for certain subgroups of students, including Hispanic, African American, and students with disabilities.

- Abstract
Rates of change in behaviors in relation to community adjustment were examined for 292 participants in the 7-year longitudinal National Adolescent and Child Treatment Study (NACTS) as they transitioned to the adult world. Participants with initially higher social-adaptive behavior and whose behavior improved over time attained higher adjustment scores. (Contains references.) (Author/CR)
