Appropriate instruction is a key component of quality physical education, which aligns student learning activities with grade-level learning outcomes. Historically, in the 1980s and late 1990s, an abundance of research was conducted to empirically link teacher effectiveness to student learning outcomes. In recent years, however, limited research has been published. Purpose: The purpose of this study was to: (a) identify research studies examining appropriate instructional practice in K-12 physical education since 2000, (b) describe the study characteristics and summarize the findings, (c) compare research to the SHAPE America's guidelines for appropriate instruction, and (d) make recommendations for future research. Methods: This study was conducted using the Preferred Reporting Items for Systematic Reviews (PRISMA) standards of quality for reporting meta-analyses. A systematic search of five electronic databases was conducted. Two reviewers retrieved articles, assessed risk of bias, and performed data extraction. The findings were synthesized using a descriptive analysis. Results: A total of 37 articles met the inclusion criteria. A thematic analysis was conducted to reduce the included articles into four themes that influenced student outcomes: (1) student engagement and participation, (2) motivation, (3) student learning, and (4) physical activity and fitness. Conclusions: This review of the literature provides evidence of the benefits of effective teaching practices and suggests that future studies in instruction should focus on teacher effectiveness and its relation to student learning outcomes. Recommendations and future directions are discussed. [ABSTRACT FROM AUTHOR]

Objective: To examine children's energy expenditure (EE) during object projection skill performance at three intensity intervals. Methods: Children's (42, Mage = 8.1) average metabolic equivalents of task (METs) were calculated using a COSMED K4b2 while they repeatedly performed blocks of kicking, throwing (overhand), and striking (two-handed) during 6, 12, and 30-s interval conditions. A repeated-measures analysis of covariance examined differences in METs while controlling for skill level. Results: Data indicated a main effect for interval condition (df = 2, 123, F = 94.36, p <.001, η2 =.605). Post hoc t-tests demonstrated decreasing performance interval times yielded progressively higher METs (p <.001) across the three conditions (30s = 4.5±0.8 METs, 12s = 6.3±1.3, 6s = 8.3±1.6). There also was a main effect for sex (df = 1,120, F = 52.28, p <.001 η2 =.305). Boys demonstrated higher METs at each performance interval (p <.001). Conclusion: Skill practice with a maximum of one trial every 30s resulted in the equivalent of at least moderate physical activity (>4.0 METs) and intervals of 6s demonstrated vigorous physical activity (>7.0 METs). Practicing/performing object projection skills, even at intervals that allow for adequate instruction and feedback (i.e., 1 trial/30s), promotes MVPA in children. [ABSTRACT FROM AUTHOR]

This paper examined relationships between qualitative (developmental sequences) and quantitative (time) performance in rising from a supine position in early childhood. One hundred twenty two children ranging in age from 3 to 5 years were videotaped for five trials of rising from a supine position. Children's performance on the supine-to-stand (STS) task was quite variable in terms of both qualitative movement patterns and time (mean = 2.37 s, SD =.60). Results: Component sequences were moderately to strongly correlated with each other (r =.387 to.791). Upper-extremity (r = –.383) and axial (r = –.416) component levels also were inversely correlated with STS time. Results indicated a strong coordinative link between the development of trunk control (i.e., axial movement) and upper-extremity movement levels (r =.791), and together they demonstrated the strongest impact on the ability to rise quickly. These data provide important information relating to a child's motor development that may have clinical relevance for diagnosis. It provides also a greater understanding on how to improve performance on this task. Future research should examine qualitative and quantitative aspects of STS performance to understand its predictive utility as a lifespan assessment of motor competence and its potential importance as a measure to predict healthrelated variables and functional capability across the lifespan.

A person's ability to rise from the floor to a standing position is seen as a precursor for establishing and maintaining bipedal independence. It also is an important primer for the development of other fundamental movement skills and is associated with functional capacity in later life. Thus, the potential importance of developing this movement capability early in life and understanding how it may relate to global function (i.e., motor competence [MC]) across the lifespan may be underestimated. Therefore, this study examined the validity of supine-to-stand test (STS) as a developmental measure of functional MC across childhood into young adulthood using a pre-longitudinal screen approach and examining associations between movement components. STS time also provided a secondary measure of developmental validity in addition to an examination of the concurrent validity of STS against developmentally valid measures of MC (i.e., throwing, kicking, hopping, and standing long jump) in these age groups. Overall, results indicated that cross-sectional data "curves" for the STS components generally fit Roberton's hypothetical model curves. STS time demonstrated weak to moderate (r = −.28 to −.64) correlations to MC product measures across all age groups indicating that STS time can be considered a valid and reliable measure of MC across childhood into young adulthood.

This paper examined relationships between qualitative (developmental sequences) and quantitative (time) performance in rising from a supine position in early childhood. One hundred twenty two children ranging in age from 3 to 5 years were videotaped for five trials of rising from a supine position. Children's performance on the supine-to-stand (STS) task was quite variable in terms of both qualitative movement patterns and time (mean = 2.37 s, SD = .60). Results: Component sequences were moderately to strongly correlated with each other (r = .387 to .791). Upper-extremity (r = -.383) and axial (r = -.416) component levels also were inversely correlated with STS time. Results indicated a strong coordinative link between the development of trunk control (i.e., axial movement) and upperextremity movement levels (r = .791) and together they demonstrated the strongest impact on the ability to rise quickly. These data provide important information relating to a child's motor development that may have clinical relevance for diagnosis. It provides also a greater understanding on how to improve performance on this task. Future research should examine qualitative and quantitative aspects of STS performance to understand its predictive utility as a lifespan assessment of motor competence and its potential importance as a measure to predict healthrelated variables and functional capability across the lifespan.

Since the early 1990s, notions about the purpose of physical education (PE) in the United States have increasingly aligned with a public health agenda driven by concerns that youth accrue too little physical activity (PA). In tandem with the shifting tides of thought about PE's purpose, authors have proposed numerous public health-aligned recommendations for physical educators in schools and teacher education. These ideologies and recommendations can be conceptually organized using the comprehensive school physical activity program (CSPAP) model, which includes five components: (1) physical education, (2) PA during school, (3) PA before and after school, (4) staff involvement, and (5) family and community engagement. This article discusses the expanded professional roles of the PE teacher within each CSPAP component, identifies specific strategies for performing these roles, and suggests learning tasks that physical education teacher education faculty can incorporate into their programs to help teacher candidates adopt each strategy.

Objectives: The Aptima and Cervista tests (Hologic/ Gen-Probe, San Diego, CA) were compared for detection of high-risk human papillomaviruses (HPV) in cervical cytology specimens. Methods: A total of 208 specimens were tested with both tests, and those with discordant results were tested with the Cobas HPV test (Roche Diagnostics, Indianapolis, IN). HPV test results were correlated with cytologic findings for all specimens and concurrent cervical biopsy specimens in 31 women. Results: The agreement between the results of the two tests was only 88% (McNemar test, P < .001). HPV was detected by both tests in 83 specimens, by Aptima alone in two, and by Cervista alone in 23. Both tests were negative in 100 specimens. One (50%) of two specimens positive by Aptima alone and only five (22%) of 23 specimens positive by Cervista alone were positive by the Cobas test. Of the 23 Cervista-positive/Aptima-negative specimens, 13 were positive in all three of the Cervista reaction mixtures for HPV clades A5/A6, A7, and A9, and 85% of these had high human genomic DNA fold-over-zero ratios (≥15). Conclusions: We found poor positive percent agreement between the results of the Aptima and Cervista HPV tests and described an important source of false-positive Cervista results.

Purpose: The purpose of this article is to provide a summary of contemporary empirical evidence supporting the need for the essential components of physical education as the minimum threshold of quality. The collective findings from a series of systematic reviews conducted through university, community, and the Centers for Disease Control and Prevention (CDC) collaborations are timely and warranted given the current trends in physical inactivity and obesity among youth and emerging adults. Methods: Faculty and students from five doctoral physical education teacher education programs (D-PETE) conducted distinct but interrelated systematic reviews of the Essential Components of Physical Education—policy and environment, curriculum, instruction, and assessment. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (identify, screen, determine eligibility, and include), relevant studies were extracted from six databases. Only peer-reviewed publications related to each essential component were examined. Full papers were included in the final analysis if they were published between January 2000 and May 1, 2020, had a primary outcome related to PreK–12 physical education, and were empirical and original investigations. Results: Each essential component, in part, was empirically supported. Some actionable criteria for a given component were underdeveloped and in need of more empirical research to advance our understanding of policy and environment, curriculum, instruction, and assessment in authentic contexts. Conclusions: Implications for the essential components of physical education and future directions for K–12 physical education, teacher education, and research are outlined in this article.

Purpose: This introductory article provides the context and rationale for conducting systematic literature reviews on each of the essential components of physical education, including policy and environment, curriculum, appropriate instruction, and student assessment. Methods: Four research teams from Doctoral Physical Education Teacher Education programs (D-PETE) conducted these systematic reviews using the PRISMA guidelines process. Results: This article explains the role of the national framework for increasing physical education and physical activity (i.e., Comprehensive School Physical Activity Program) in supporting the essential components of physical education. It also highlights the expectations for physical education and provides a brief history of these components. Lastly, this article highlights each of the articles presented in the special feature. Conclusion: Understanding the implementation of these components may be important for improving the physical education experience for all students and creating a foundation for lifelong physical activity and health.

Purpose: To compare children's energy expenditure (EE) levels during object projection skill performance (OPSP; e.g., kicking, throwing, striking) as assessed by hip- and wrist-worn accelerometers. Method: Forty-two children (female n = 20, Mage = 8.1 ± 0.8 years) performed three, nine-minute sessions of kicking, over-arm throwing, and striking at performance intervals of 6, 12, and 30 seconds. EE was estimated using indirect calorimetry (COSMED k4b2) and accelerometers (ActiGraph GT3X+) worn on three different locations (hip, dominant-wrist, and non-dominant-wrist) using four commonly used cut-points. Bland-Altman plots were used to analyze the agreement in EE estimations between accelerometry and indirect calorimetry (METS). Chi-square goodness of fit tests were used to examine the agreement between accelerometry and indirect calorimetry. Results: Hip- and wrist-worn accelerometers underestimated EE, compared to indirect calorimetry, during all performance conditions. Skill practice at a rate of two trials per minute resulted in the equivalent of moderate PA and five trials per minute resulted in vigorous PA (as measured by indirect calorimetry), yet was only categorized as light and/or moderate activity by all measured forms of accelerometry. Conclusion: This is one of the first studies to evaluate the ability of hip- and wrist-worn accelerometers to predict PA intensity levels during OPSP in children. These data may significantly impact PA intervention measurement strategies by revealing the lack of validity in accelerometers to accurately predict PA levels during OPSP in children.

This study compared the energy expenditure (EE) levels during object projection skill performance (OPSP) as assessed by indirect calorimetry and accelerometry. Thirty-four adults (female n = 18) aged 18–30 (23.5 ± 2.5 years) performed three, 9-min sessions of kicking, over-arm throwing, and striking performed at 6-, 12-, and 30-sec intervals. EE was estimated (METS) using indirect calorimetry (COSMED K4b2) and hip-worn accelerometry (ActiGraph GT3X+). EE using indirect calorimetry demonstrated moderate-intensity physical activity (3.4 ± 0.7 METS––30-sec interval, 5.8 ± 1.2 METS––12-sec interval) to vigorous intensity physical activity (8.3 ± 1.7 METS––6-sec interval). However, accelerometry predicted EE suggested only light-intensity physical activity (1.7 ± 0.2 METS––30-sec interval, 2.2 ± 0.4 METS––12-sec interval, 2.7 ± 0.6 METS––6-sec interval). Hip-worn, ActiGraph GT3X+ accelerometers do not adequately capture physical activity intensity levels during OPSP, regardless of differences in skill performance intervals. [ABSTRACT FROM AUTHOR]

The article discusses a study that examines the developmental trajectory of perceptions of motor competence of children ages 3 to 13 years with and without visual impairments. Study highlights include the use of the United States Association of Blind Athletes system, the Test of Perceived Motor Competence for Children with Visual Impairments, and the use of Pearson Product Moment correlations to examine links among age and perceptions of motor competence.
