Purpose: Guided by the cognitive load theory, the purpose of this study was to determine the impacts of cognitive load and school socioeconomic status-related environmental factors on ninth-graders' energy-balanced living knowledge gain. Methods: A stratified random sample of high-school students (N = 150) participated in this study. Data were collected on students' knowledge gain, cognitive load, free and reduced-price meal rates, and student-to-teacher ratio. Results: The path analysis results revealed that the reasoning learning tasks had direct significant effects on students' knowledge gain ([beta][subscript i-Diet and i-Exercise] = 0.34, p < 0.01). The free and reduced-price meal rates and student-to-teacher ratio did not have significant effects on students' knowledge gain (p > 0.05). Discussion: These findings advance our understanding of the role cognitive learning tasks play in enhancing student learning in the subjects of energy-balanced knowledge and healthy lifestyle

Purpose: Informed by the constructivist learning theory, the purpose of this study was to determine the impact of three continuing professional development (CPD) approaches on student learning in a healthful living physical education curriculum. Methods: Physical education teachers (n = 19) received one of the following CPD trainings: (1) "Full Training"; (2) "Expedited Training"; or (3) "Self-Training." The effect of each CPD method was determined by tracking student learning (N = 3,418) with a two-level linear mixed model. Results: The results showed that "Full Training" CPD was able to generate the largest knowledge gain in both the "Healthy Lifestyles Unit" ([beta] = 0.214, p < 0.001) and "Cardio Fitness Club Unit" ([beta] = 0.184, p < 0.01) in comparison with the other two CPD approaches. Discussion: These findings advance our understanding of the role different CPD approaches play in enhancing student learning in the subjects of cardiorespiratory fitness and health lifestyles. Conclusions: The "Full-Training" CPD appears to benefit student learning the most followed by the "Expedited-Training." The "Self-Training" would yield the least learning achievement.

Purpose: The purpose of this study was to determine the 3-year trajectory of students' interest in learning physical activity (PA) knowledge during middle school and the effects of gender and prior knowledge on the trajectory. Methods: Using a repeated-measures design, a cohort of 447 sixth-grade students' interest in learning PA knowledge was measured eight times from the beginning of sixth grade to the end of eighth grade. Students' prior PA knowledge was measured at the beginning of sixth grade. Results: Hierarchical linear modeling analyses showed that students' interest in PA knowledge in general declined over time. Girls' interest declined faster than that of the boys before eighth grade, but their decline slowed during the eighth-grade year. Prior knowledge did not influence the trajectories. Discussion: These findings provide insights regarding students' interest in learning PA knowledge and indicate that prior knowledge may not be a central component that contributes to interest development.

Purpose: Guided by the model of domain learning theory, this study was intended to determine the extent to which integrating a 10-min physical activity (PA) break in elementary school mathematics lessons would enhance the learning of mathematics content. Methods: A sample of 22 intact classes from a random sample of eight schools in Taiwan were randomly assigned to an experimental condition with PA breaks (n = 11) and a control condition (n = 11) for 12 weeks. Students' (N = 420) mathematics knowledge was assessed using the standardized aptitude tests accompanying the curriculum, which encompassed five knowledge domains. Results: Analysis on class means showed that adding the PA breaks did not benefit mathematics learning, which lends support to the model of domain learning theory. Discussion/Conclusion: The findings seem to question the theoretical foundation for adding PA breaks to classroom-taught content, including mathematics. Although interdisciplinary or cross-disciplinary instruction and learning may be necessary to advance students' knowledge, including PA in classroom-taught subjects needs extensive research.

Purpose: Cognitive load theory focuses on providing appropriate cognitive engagement to facilitate knowledge learning. The purpose of this study was to determine the contributions of cognitive load on high school students' in-class physical activity. Method: A stratified random sample of high school students (N = 150) who participated in a large curriculum intervention study provided the data. A path analysis and Hayes' PROCESS analysis were used to test a correlation model and moderation effect from gender and race. Results: The results showed that the reasoning learning tasks directly contributed to their in-class physical activity (path coefficient =.54, p <.01) and the gender and race factors were not significant moderators (p >.05). Conclusion: The findings imply that high cognitive load tasks can facilitate in-class physical activity. The findings suggest the power of the concept-based physical education curriculum in providing productive learning opportunities to all students. [ABSTRACT FROM AUTHOR]

The purpose of the study was to determine the extent to which practicum teaching could lead to value orientation change of preservice physical education teachers. A group of preservice physical education teachers (N = 28) in China were randomly assigned to practicum-teach either a health-related fitness unit or a traditional sport unit. Their value orientations were measured before and after the practicum teaching. Their middle school learners were tested for knowledge gain. A repeated-measures model shows that the practicum teaching led to little change in their value orientations. The learners in the health-fitness curriculum gained more knowledge than those in the traditional curriculum. The findings suggest that an attempt to influence the value orientation in one practicum teaching experience may not be successful. The findings imply that physical education teacher education training programs may emphasize not only how to teach (via teaching methods courses), but also nurturing the values of teaching to meet the society needs.

Purpose: Guided by the declarative-procedural knowledge framework, the study attempts to identify middle school students' declarative (knowing what) and procedural (knowing how) fitness knowledge and the relationship between the two. Methods: A sample of students (n = 291, age 11-14 years) from 24 middle schools took a grade-relevant standardized knowledge test on declarative fitness knowledge and received a semistructured interview designed to clarify their declarative and procedural knowledge. Results: Most students were lacking in procedural knowledge to conduct fitness-enhancing physical activities. A few students who had mastered declarative fitness knowledge demonstrated a high level of procedural knowledge consistent with personal fitness goals. Discussion: The findings suggest that incapability to engage in fitness-enhancing physical activities could be a result of lacking procedural fitness knowledge. Future school-based interventions may prioritize procedural knowledge learning for actual physical activity participation.

Purpose: Based on the theorized concept "Curriculum Safety Zone (CSZ)," this study was conducted to identify the factors for breaking CSZ by contrasting the experiential accounts of two pre-service teacher groups who taught within or outside of their CSZ. Method: Pre-service teachers (n = 14) from a sport-centered PETE program were trained to teach a Health-First curriculum module and their peers (n = 14) a traditional sport module. Each group taught their respective module to 14 intact 7th grade classes in 14 schools in China. A mixed-methods design was used. Quantitative data on learner knowledge gain were collected from the learners. Qualitative data included lesson observation fieldnotes, social-media posts, and interview responses and were gathered from the pre-service teachers. Results: Learners in the Health-First schools gained more knowledge than those in the Comparison schools (t[subscript 26] = 2.92, p = 0.007, Cohen's d = 1.10). Qualitative evidence was triangulated using a Health-First vs. Comparison contrasting approach with open-, axial-, and selective-coding to generate themes. The themes were Confidence in Doubt, Lesson Plans to the Rescue, Professional Development is Necessary But…, and Student Learning Save the Day! A grounded theory was developed using the themes and interpreted using the Interconnection Model of Teacher Professional Growth. Conclusion: Breaking CSZ requires a synergistic effort with carefully designed professional development, detailed lesson plans, an effective support network, and, most important of all, a powerful curriculum that can elicit observable and measurable learner achievement.

Purpose: It is argued that the constructivist physical education has the potential to overcome socioeconomic (SES) constraints and promote learning. The purpose of this study was to determine the extent to which school SES-related class environmental factors influenced student learning in a constructivist physical education context. Methods: Students in 8th grade (N = 1,256) from 10 middle schools with varied SES were tested on exercise knowledge before and after a constructivist physical education intervention. School SES was determined using free and reduced meal ratio (FARM) and physical education related factors. Data on lesson frequency, length, facilities, equipment, and class size were collected from teachers. Results: Hierarchical linear model analyses reveal that SES is not predictive of intervention induced learning ([gamma] = 0.73, t =0.91, p =0.37). Lesson frequency ([gamma][subscript 02] =0.52, t =0.31, p =0.06), length ([gamma][subscript 03] = -0.03, t = -1.82, p =0.07), facilities ([gamma][subscript 04] = -0.11, t = -0.49, p =0.63), equipment ([gamma][subscript 05] = -0.36, t = -1.36, p =0.18), and class size ([gamma][subscript 06] = -0.05, t = -1.36, p =0.18) are not predictive of learning. Student prior knowledge ([gamma] = -0.59, t = -18.37, p <0.001) and teacher factor ([gamma] =0.04, t = 3.72, p <0.001) are predictive of learning. Conclusion: The findings suggest that school SES's detrimental impact on learning in physical education could be overcome by the power of a constructivist curriculum.

We used mixed methods to identify middle school students' conceptions and misconceptions of energy in the domain of health and fitness. We selected a total of 24 middle schools from six school districts in a Southeastern state of the U. S. through stratified sampling. Students were first given a standardized knowledge test to establish their knowledge level membership in the domain of health and fitness. A sample of 291 students was selected from the 24 schools for semi-structured interviews on their understanding of energy sources for physical activities and consequences of energy surplus. Analysis of the interview data identified a variety of misconceptions on energy by grade and knowledge levels. Different conceptual change theories were adopted to form four themes to explain the identified misconceptions. We discussed pedagogical implications that may help address the misconceptions in and beyond the domain of health and fitness.

Purpose: It has been acknowledged in physical education (PE) that knowledge empowers learners to develop a physically active lifestyle In this study, we consider Cognitive Load Theory (CLT) as a valuable extension of the constructivist learning theory to help articulate the role of three pivotal instructional factors, content knowledge, learners, and instructional process, in learning fitness knowledge in PE. Guided by CLT, this study was intended to identify middle school students' cognitive architecture about aerobic and anaerobic concepts and pedagogical factors that might enhance or limit scientific conceptualization. Methods: We employed a mixed-methods approach. A total of 291 students randomly drawn from the 24 schools provided data on conceptual knowledge levels via standardized test and conceptual structures of understanding via semi-structured interviews about the aerobic/anaerobic concepts. Results: Results from integrated quantitative and qualitative analyses reveal the role of task element interactivity as a function of conceptualization in the students' cognitive architecture. The students lack the understanding that aerobic and anaerobic concepts are associated with the concepts of complex metabolic systems that dictate the energy pathways experienced in physical activity. Their understandings are characterized by a tendency of overly simplifying the complex conceptions for convenient schema activation. The simplified conception is likely to prohibit their understanding from becoming consistent with the science. The findings suggest that teachers should anticipate lack of understanding of knowledge connectivity when teaching fitness concepts and establish the task element interactivity with enhanced clarity to facilitate knowledge learning. Conclusion: Consistent with the constructivist learning theory, the findings inform us that teaching complex fitness concepts require the teacher to connect prior knowledge as a prerequisite to activate relevant cognitive architecture and actively build connections between the prior knowledge and the to-be learned concepts. PE curriculum designers and teachers should anticipate the complex challenges in teaching the aerobic and anaerobic concepts because of their connections to other concepts associated with human energy systems such as intensity and oxygen supply.

Purpose: This study aimed to determine the extent to which a concept-based physical education curriculum, specifically the Science of Healthful Living (SHL) curriculum, influenced middle school students' knowledge, motivation for physical education (PE) and physical activity (PA), and out-of-school PA. Methods: A static group comparison design was adopted to analyze the differences on fitness knowledge, autonomous motivation for PE and PA, and out-of-school PA between eighth-grade students who studied the SHL curriculum (the experimental condition, n = 168) and their peers who studied a multiactivity PE (the control condition, n = 226) 1 year earlier. Results: The students who studied the SHL curriculum demonstrated significantly higher levels of knowledge (p < 0.05, Cohen d = 0.81), autonomous motivation toward PA (p < 0.05, Cohen d = 0.20), and out-of-school PA (p < 0.05, Mann--Whitney U effect size = 0.01) than students who had experienced the multiactivity PE. The students in both conditions were equally motivated in their respective PE courses. Conclusion: The SHL curriculum is effective in promoting students' PA behavior outside of the school.

One primary goal of physical education (PE) is to promote students' lifelong physical activity (PA). This goal implies that PE should not only improve students' PA in PE classes but also promote their PA outside of the school known as the "PE effect." Purpose: In this study, we proposed a two-pathway model of the "PE effect" and hypothesized that learning in PE and positive motivational experience in PE are two possible pathways through which the "PE effect" emerges. We tested the tenability of this two-pathway model from the perspective of knowledge learning and autonomous motivation in PE. Methods: A total of 394 eighth-grade students from five schools provided data on PA knowledge, out-of-school PA, and autonomous motivation toward PE and PA. Structural equation modeling was used to test the two-pathway model. Results: Results showed that the students' knowledge had a direct effect ([beta] = 0.18, p < 0.05) on their autonomous motivation for PA and an indirect effect ([beta] = 0.02, p < 0.05) on out-of-school PA through influencing autonomous motivation toward PA. Students' autonomous motivation for PE had a direct effect ([beta] = 0.41, p < 0.05) on their autonomous motivation toward PA and an indirect effect ([beta] = 0.04, p < 0.05) on out-of-school PA through autonomous motivation toward PA. Conclusion: These results indicate that the two-pathway model is tenable in terms of knowledge learning and autonomous motivation in PE and imply that teaching knowledge in an autonomy-supportive PE environment may be an effective way to promote students' out-of-school PA.

Acquiring scientific knowledge about physical activity is necessary for students to become physically literate for life, and cognitive engagement and cognitive levels of tasks are two components that often determine the effectiveness of knowledge acquisition. This study sought to determine the extent to which students' cognitive engagement in descriptive, relational and reasoning learning tasks contributed to their acquisition of knowledge and the extent to which cognitive engagement on lower-level tasks contributed to higher-level tasks (e.g. descriptive to relational to reasoning). The performance of students in descriptive, relational and reasoning tasks and knowledge acquisition was measured in 992 middle school students in active physical education lessons. The results revealed that students' performance in relational (regression coefficient = 0.09, p < 0.01) and reasoning (regression coefficient = 0.06, p < 0.01) tasks directly contributed to their acquisition of knowledge (R[superscript 2] = 0.14). The performance of students in descriptive tasks indirectly contributed to knowledge acquisition through influencing their performance in relational and reasoning tasks (indirect effect = 0.09, p < 0.01).

There are substantial differences between the Chinese and US education systems. One difference is in the design and use of assessment due to differences in educational policies. This study described the differences in student learning outcomes, instructional approaches, and learner motivation in physical education as consequences of the policies in the two countries. Objectively measured data on skill and knowledge achievement and instructional procedures, and self-report data on student motivation were collected from a random sample of 870 students in 24 whole classes from eight Chinese middle schools and 1213 students in 39 classes from 15 US middle schools. Multivariate analyses of variance on class means revealed that Chinese students outperformed their US peers in skills, perhaps because skills were part of the high-stake tests for advancement in schooling. They were outperformed by the US students in a fitness knowledge test, perhaps because knowledge was not part of the high-stake tests. The differences in learning outcomes, instructional approaches, and motivation seem to suggest strong differentiated influences from the two countries' respective educational environments and assessment policies.

The purpose of this study was to explore and reveal naïve conceptions and misconceptions about energy embedded in elementary school students' prior knowledge. Students' performance on standardized knowledge test was used to classify students into low, median and high levels of knowledge about the cardiovascular system. Semi-structured in-depth interviews were conducted with students in each group to extract their understanding of energy in relation to food choices, physical activities, and exercises. Analysis of the interview data generated six categories of naïve conceptions and two categories of misconceptions. Different conceptual change theories, including Chi's ontological change theory, Ohlsson's resubsumption theory, and enculturation theory were used to analyze and understand these naïve conceptions and misconceptions and why they could be robust to change. The analyses confirm the need to adopt a multi-theoretical approach to the understanding of students' naïve conceptions and misconceptions (Chinn & Samarapungavan, 2009. Conceptual change-multiple routes, multiple mechanisms: A commentary on Ohlsson. Educational Psychologist, 44(1), 1-10). The findings encourage physical and health educators adopt different strategies to address the potential learning obstacles brought by students' naïve conceptions and misconceptions.
