Secondary School Physical Education Teachers’ Understanding and Practical Reflection of Competence-Based Curriculum Design

<p>十二年國民基本教育所欲培育的核心素養為各學科的重要依據，惟中學體育教師對素養導向課程概念常未能有效與其教學實踐有效連結。依此，本研究運用逆向式課程設計（backward design），採逆向發展的設計與課程校準，引導教師朝向情境化、脈絡化、整合式的學習經驗設計，協助體育教師建立素養導向課程的深入理解概念，作為後續支持中學體育教師專業發展與實踐之參考。本研究選取5位中學體育教師及1位體育師資培育教授為研究對象，組織4次實務社群會議。資料蒐集採半結構式訪談、參與觀察、持續比較和歸納分析資料。結果顯示：一、社群運作初期，教師感到教學與評量間的矛盾，評量仍著重於技能學習；二、社群運作中，教師將目標設定、學習評量以及學習內容來回校準，嘗試化解「既有現場教學經驗」與「探究學習」間的矛盾，但對於素養導向評量概念尚未純熟；三、社群運作結束後，教師給予逆向式課程設計正向的評價，但在教學實踐上仍有挑戰與困難。逆向式的課程設計有利於化解教師對於素養導向在知識概念與教學行動經驗間的衝突，在教師社群共備之下，持續進行專業教學對話與反思，成為素養導向體育教師增能培力之新策略。</p><p>The core competencies that 12-year Compulsory Education aims to develop are the basis of the curriculum development for each subject. Competence-based Physical Education （CBPE）curriculum, however, has not yet been popularized and implemented. The purpose of this study was to examine the backward design, and structure of the physical education unit intended to enhance physical education teachers’ understanding and practical application of competency-oriented curriculum design. Five secondary school physical education teachers and one physical education teacher education professor was selected for this study, and four learning communities were organized. Data were collected through semi-structured interviews, participant observation, continuous comparison, and inductive analysis. Results were as follows: (1) In the initial community, teachers identified a contradiction between teaching and assessment, although assessments still emphasized skill acquisition; (2) During the community operation, teachers worked towards aligning the curriculum with learning objectives, assessment methods, and learning content, aiming to address the tension between "field teaching experience" and "inquiry learning"; however, they were not yet familiar with the CBPE assessment concept; (3) After the community operation, teachers provided positive feedback on the backward design approach, but encountered challenges and difficulties in implementing it during their teaching practice. Through the co-planning mechanism of teacher learning communities, which encourages dialogue and reflection in Physical Education classes, becoming a competence-based physical education teacher becomes a new strategy for enhancing abilities and training.</p> <p> </p>

Modelling the associations between academic engagement, study process and grit on academic achievement of physical education and sport university students

ObjectiveThe present study examined the impact of academic engagement, study processes, and grit on the academic achievement of physical education and sport university students. MethodsAn internet-based survey recruited 459 university students aged 19–25 years (M = 21 ± 1.3) in physical education and sports (PES) to fill out questionnaires on Physical Education-Study Process Questionnaire (PE-SPQ), Physical Education-Grit (PE-Grit), academic engagement (A-USEI), and Grade Point Average (GPA). A path analysis was carried out to understand variable relationships.ResultsData from each variable exhibited symmetrical and normal distribution, as indicated by the skewness and kurtosis values. The model’s fit indices showed sufficient Comparative Fit Index (CFI = 0.92), Tucker-Lewis Index (TLI = 0.90), Goodness of Fit Index (GFI = 0.99) and Normed Fit Index (NFI = 0.90) and showed acceptable levels. The results indicated a statistically significant positive impact of engagement (β = 0.299, p < 0.001) and study processes (β = 0.397, p < 0.001) on academic achievement. However, the effect of grit on achievement was non-significant.ConclusionsAcademic engagement as well as study processes are two important factors predicting academic achievement while grit seems to be not a major predictor. Hence, physical education and sport faculty and university administrators should prioritize student engagement as a determinant of academic outcomes by reforming or redesigning physical education and sport curriculum modules that can facilitate engagement.

Review of Physical Education Curriculum Design for Primary and Secondary School Students in Malaysia for the Purpose of Health Promotion in the Past Ten Years

Among both primary and secondary school students, physical education (PE) plays a critical role in encouraging pupils to take responsibility for their own health on multiple levels. This narrative literature review focuses on examining the design of the PE curriculum for health promotion within the Malaysian context over the past decade. Employing a narrative literature review approach, a total of 118 articles were scrutinized from an initial pool of 157. This comprehensive analysis aimed to uncover key variables influencing PE curriculum design and its role in health promotion. The review identified critical variables shaping health promotion through PE. Curriculum content, teaching methods, teacher training, professional development, stakeholder involvement, and health promotion outcomes were all included. The evaluation emphasized how important it is to have curriculums that are based on evidence, to use effective teaching methods, and to give teachers chances to improve their skills. These factors emerged as essential contributors to promoting health among students. Furthermore, the study highlighted the importance of involving various stakeholders in the curriculum design process and emphasized the necessity of evaluating health promotion outcomes. There is a clear need for further investigations into the intricate relationships between these variables and health promotion outcomes. Additionally, it suggests the formulation of comprehensive policy guidelines and standards for PE within the Malaysian educational system. In conclusion, this literature evaluation may help practice and policymakers create effective PE programs. Malaysia may improve student health through physical education by using evidence-based curriculum design, teacher training, and stakeholder interaction.

Enhancing visual-motor integration and visual perception of 6-year-old children

Background: Perceptual motor development is crucial during early childhood and not properly addressing it in physical education (PE) can be detrimental.Aim: To determine the effect of a South African curriculum-aligned PE intervention on the visual-motor integration (VMI), visual perception (VP) and motor coordination (MC) of 6-year-old children.Setting: Quintile 3 schools in Mangaung, Free State Province, South Africa.Methods: Grade 1 children from two quintile 3 schools in Mangaung were recruited. Complete data sets were obtained for 44 participants. A quantitative randomised control trial design was followed. The Beery-Buktenica Developmental Test of Visual-Motor Integration, Sixth Edition (Beery VMI-6), determined participants’ VMI, VP and MC during the pre- and post-tests. The KaziKidz toolkit was used as intervention during 10 sessions of 40 min each for the experimental group, while the control group continued with the South African PE curriculum. The Fisher’s exact and Kruskal–Wallis tests were used for pre- and post-test comparisons, with p 0.05 indicating statistical significance.Results: The median age of the control (n = 18) and intervention (n = 26) groups was 6.7 and 6.5 years, respectively. Post intervention, the intervention group displayed significantly improved VMI (p = 0.042) and VP (p 0.001), compared to the control group. No significant differences between the groups were observed for MC.Conclusion: Exposure to PE including perceptual motor aspects significantly improved the VMI and VP of 6-year-old children.Contribution: Results deemed the KaziKidz toolkit to be a successful mode of PE delivery to improve the perceptual skills of Grade 1 learners in South Africa.

Moderate-to-vigorous intensity physical activity levels of children with intellectual disability during physical education classes.

Physical education (PE) class is an excellent way to improve moderate-to-vigorous intensity physical activity (MVPA). Increasing number of research has explored the children's PA based on movement during PE classes, but data for children with intellectual disability (ID) is still lacking. The purpose of this study was to investigate the current status of MVPA levels of children with ID during PE classes in China, as well as differences of MVPA levels according to gender and grade. Accelerometers were used to record MVPA levels of fifty-three children with severe ID from 9 to 16 years of age (mean age: 12.60 ± 1.66 years) during standard PE classes. The mean time spent in MVPA during PE classes was 8.00 ± 2.10 min, meaning only 22.88% of PE class time was spent in MVPA. As grade levels progresses, time spent in MVPA during PE classes tended to decrease; the fourth-grade children tended to spend more time in MVPA during PE classes compared with the fifth-grade and the sixth-grade (9.15 vs. 7.61 vs. 7.25 min, all p < 0.05). Boys spend significantly more time in MVPA during PE classes than girls; both in the entire sample (9.20 vs. 5.70 min) as well as in each grade (9.76 vs. 6.09 min, 9.35 vs. 5.68 min, 8.31 vs. 5.59 min, all p < 0.05). Findings from this study indicate that the proportion of PE class spent in the MVPA of children with ID was lower than the 50% recommended by the U.S. Department of Health and Human Services (DHHS) and U.K. Association for Physical Education (AfPE). And the amount of MVPA participation varied by the grade and gender as well as by the activity performed. Therefore, in order to help children with ID achieve MVPA goals, educators need to reevaluate the PE curriculum as well as take due consideration of grade and gender when devising new content.

Physical Education Major in Colleges and universities is the main force to cultivate excellent physical education reserve talents in China. In order to improve the training quality of compound talents in physical education, this study takes the curriculum of physical education major in colleges and universities as the research object, and studies the curriculum structure, curriculum teaching mode, curriculum practice and curriculum evaluation of the curriculum of physical education major. The research shows that optimizing physical education curriculum based on OBE concept can meet the needs of physical education curriculum construction, deepen the curriculum reform of physical education, and help achieve the goal of training physical education professionals. However, based on the current research results, it is found that there are corresponding deficiencies in the implementation of each part. Therefore, this study puts forward the corresponding reform strategies according to the five contents emphasized by the OBE concept: everyone can succeed, personalized evaluation, proficiency, performance responsibility and ability standard. For the course structure, we should increase the types of elective courses and improve the proportion of technical courses; For the classroom teaching mode, adopt the flexible organization form of the course, update the design structure of the course and enrich the teaching methods of the course; For curriculum practice, we should pay attention to curriculum teaching practice and strengthen educational practice; For curriculum evaluation, comprehensive evaluation content and diversified evaluation methods are adopted.

Assessment of the Attitude and Academic Performance of the Elementary Learners in Physical Fitness: Basis for an Intervention Plan

The current educational landscape is continuously evolving, and with it, so is the role of schools in equipping learners for these changes. This study aimed to evaluate the attitudes and interests of elementary learners towards Physical Fitness in the District of Columbia and its impact on academic performance, to inform the development of an intervention plan. Employing a descriptive-correlational research design, the study assessed the distance learning performance of these learners during the 2021-2022 school year. The findings indicate a generally positive disposition of learners towards using various learning platforms, which facilitated independent practice. It was observed that academic performance in physical education was not significantly influenced by physical fitness tests or by mathematics and reading performance. Conclusions drawn from the study suggest that physical education does not adversely affect academic achievement. Therefore, it is recommended that school administrations continue to support and expand intervention programs in physical education. Collaboration between Physical Education teachers and teachers of other subjects is advised to enhance learner attitudes and develop additional physical activities. Further recommendations include strengthening the Physical Education curriculum, investigating other factors influencing performance in Physical Education, and encouraging learner participation. Future research could expand the scope to include more grades and examine the broader relationship between physical fitness and academic performance for a comprehensive understanding.&#x0D;

Evaluation Of Physical Education Independent Curriculum Through CIPP: Managerial Implementation In Learning Activities

The government has created an independent curriculum as a learning recovery, but not all schools implement it well. Therefore, an evaluation is needed, especially regarding the management of learning activities. The purpose of this study is to evaluate the implementation of the independent curriculum model in physical education subjects at State Vocational Schools in Tasikmalaya City. This research used a qualitative descriptive approach. In this study, data were collected through triangulation techniques consisting of observation, semi-structured interviews, and documentation. This study involved the vice principal for curriculum, four physical education teachers, and four students. They were selected through a purposive sampling technique. Data analysis involved preparation, inference, and verification. The results showed that the context evaluation of goals and objectives indicators and strength indicators had been fulfilled. However, weakness indicators related to teacher consistency in implementing learning still exist. Input evaluation on indicators of curriculum structure, PE teacher competence, teaching materials, and students have been fulfilled and run well. However, input evaluation on indicators of infrastructure availability still needs to support the continuity of PE learning. Process evaluation on indicators of implementation and implementation of assessments has gone well, but product evaluation on indicators of program achievement still needs to be improved. Implementing CIPP managerial evaluation is carried out by ensuring that the evaluation is carried out systematically, periodically, and comprehensively. Evaluation results are used as the basis for decision-making related to the improvement and development of the Physical Education curriculum. Teachers and school management play an active role in ensuring the sustainability and effectiveness of the evaluation.

Strategies of Integrating of Physical Education and Academics

The new goal and approach to physical education teaching in vocational colleges is to promote the development of students’ moral, intellectual, physical, artistic, and practical skills. To achieve this, physical education should be integrated with academics. Therefore, we analyzed the existing problems and their causes in our college’s physical education teaching and developed basic reform ideas that incorporated physical education into academic education, interspersed physical education with academic education, and co-constructed the physical and academic education based on actual teaching experiences. Besides, each school should be given adequate physical education resources, and the management methods and regulations for physical education courses should be optimized. The integrated physical education curriculum system and content should also be improved and various extracurricular activities should be carried out. In addition, a new course evaluation index should be established, which will be used to determine new teaching goals and methods.

A study on the integrated teaching model of core literacy in college physical education and health courses using multiple data fusion

Abstract This paper introduces an experiential teaching model for physical education and health courses. Secondly, the parameters of the multiple linear regression model were estimated and tested for significance based on the least squares method, and the integration of multiple data was carried out by using rough set simplification. Finally, an empirical analysis of the core literacy of physical education and health curriculum was conducted through three aspects: physical activity ability, health behavior and physical morality. The results showed that the p-values of physical exercise awareness, physical exercise habit, and health knowledge mastery and application were 0.015, 0.024, and 0.021, respectively, thus indicating that the experiential teaching model can effectively improve students’ core literacy in physical education and health curriculum.

The research objectives are to find out: (1) Implementation of Merdeka Belajar Curriculum in Physical Education, Sports and Health subjects at State Junior High Schools in Sleman Regency. (2) Obstacles in the implementation of Merdeka Belajar Curriculum in Physical Education, Sports and Health subjects at State Junior High Schools in Sleman Regency. (3) Solutions made to overcome the obstacles to the implementation of the Merdeka Belajar Curriculum in Physical Education, Sports and Health subjects. The method used mixed research. The subjects of this study were principals and Physical Education, Sports and Health teachers in public junior high schools in Sleman Regency which were taken based on random sampling. The instruments used were interviews and questionnaires. The data analysis techniques used were qualitative and quantitative. Research results: (1) Implementation of Merdeka Belajar Curriculum in Physical Education, Sports and Health subjects in State Junior High Schools in Sleman Regency is in the sufficient and good categories, namely 50.00%. State Junior High Schools in Sleman Regency have implemented the Merdeka Belajar Curriculum in stages, and have implemented Project-Based Learning which is one of the learning activities in the Merdeka Belajar Curriculum. (2) The obstacles in the implementation of the Merdeka Belajar Curriculum in the Physical Education, Sports and Health subject in State Junior High Schools in Sleman Regency are that teachers are still difficult to instill the 6 characters of the Pancasila Student Profile to students with the various characteristics that each student has. In addition, from the observations made by researchers, it can also be seen that teachers have not been able to get out of their comfort zone in teaching, as it can be seen that in teaching they are still comfortable with using the method and the teacher's lack of ability to use learning media, this can be seen when the teacher teaches mostly only explaining the material and then giving assignments to students. (3) The solution carried out in the implementation of the Merdeka Belajar Curriculum in Physical Education, Sports and Health subjects at State Junior High Schools in Sleman Regency is that teachers look for information or references about learning assessments and regularly attend training on the implementation of the Merdeka Belajar Curriculum held.

METHODOLOGICAL CONTRIBUTIONS REGARDING THE DEVELOPMENT OF THE FOOTBALL GAME TECHNIQUE IN HIGH SCHOOL STUDENTS

The traditional practice of playing football in school, means going through the technical-tactical elements of the game according to the analytical method. Each process is practiced, in order to learn, isolated, broken by the conditions of the game. No matter how adequate the methods and means used are, the exercises will not succeed in ensuring the complete, multilateral employment of the student, so that through the immediate and subsequent effects the major objectives will be achieved, which motivated the introduction of football in school. The practice of the integral game, with some simplified rules, ensures a much greater contribution and a special contribution to the involvement of football in the tasks of physical education. In the game, students are engaged multilaterally in the bio-psycho-motor plane, and the phenomena of addiction, teacher-student is diminished. During the game, the teacher intervenes in correcting some fundamental mistakes in the technical-tactical executions, or in interpreting the game rules. Integral play, however, cannot be practiced without the students having acquired a minimum of specific motor knowledge and skills. The teacher's mastery consists in knowing how much of the physical education lesson is given to learning the technical procedures separately, how much in conditions analogous to the game and how much time is allocated to the whole game. In addition to this time planning in the lesson, the teacher must also schedule new technical-tactical actions subject to the learning process and the consolidation of the technical procedures underlying the development of the game of football. Starting from the optimal, technical-tactical model of the graduate, the content of the training must be in accordance with this model and staggered on the requirements of their periodization and staging. This need is imposed by the practice of the game of football both in school - as a means of physical education, but also by the participation of students in school competitions reserved for them and which includes the entire mass of students. So, in the physical education lesson, the isolated learning of the technical-tactical elements and procedures will be short, insisting on their repetition and consolidation within the technical-tactical actions of the game, by practicing the bilateral game. The system of physical education and sports has a dynamic character, being subjected over time to changes and adaptations dictated by the social order, respectively by the state of society and its members, by technological progress and cultural level, by their aspirations. In the spirit of this dynamic, the steps of elaboration and revision of the school curricula in a curricular vision are revealed. This vision presupposes “a design in their interaction of objectives, contents, learning activities and evaluation principles and methods. The curriculum for physical education in secondary education reflects a new conception regarding the formation and complex development of the autonomous and creative personality of the students ”. The curricular area underlying the new curricula is a first step in decentralizing education, offering increased opportunities for choice, increasing the chances of an individualized teaching / learning process and increasing school autonomy in developing one's own curriculum. The methodical steps imposed by the new orientation of the physical education and sports activities in the school represent a challenge for all those involved in this process, "but the teacher will always remain the main creator of his lesson".

Efficiency of an Alternative Physical Education Program for the Lower Grades of Elementary School Children.

(1) Introduction: This research was conducted with the aim of assessing whether an alternative physical education (PE) program could effectively substitute for the traditional PE curriculum and aid in accomplishing the essential goals and objectives of PE among younger elementary school children. (2) Materials and Methods: This longitudinal 6-month study included third-grade elementary school children of both genders, who were healthy, lived in urban areas, and were involved in an alternative PE program, as well as the regular PE classes. The sample of participants comprised 214 students, with 105 participants in the experimental group and 109 participants in the control group, who underwent pre- and post-intervention measurements. For the purposes of this study, 11 variables were applied to assess the parameters of growth and development, motor abilities, and physical and health education. MANCOVA and ANCOVA methods were used to determine the effects resulting from the alternative and regular PE programs, and differences between the groups, respectively. The data are reported as the mean and standard deviations, and were analyzed using the statistical package SPSS version 20.0 (SPSS Inc., Armonk, NY, USA). (3) Results: Based on the research results obtained for motor abilities and physical and health education, it was concluded that both the alternative and regular PE programs had positive effects in achieving the goals and objectives of PE, but without statistical significance at the multivariate and univariate levels. The differences between the two groups were found to be negligible (effect size, ES < 0.2). (4) Discussion: Sports and PE have distinct objectives and approaches. While sports emphasize competition and winning, PE aims to impart fundamental skills and knowledge, prioritizing inclusivity among younger students. Success in PE is measured by the number of students meeting these goals, potentially affecting both talented and struggling learners. (5) Conclusions: The results obtained from the conducted research indicate that both the alternative PE program and the regular PE program influence changes in motor abilities and physical and health education to a limited extent. The alternative PE program proposed in this study, with its modifications to the structure of existing, regular PE program, can fully replace the latter in schools that do not meet the required spatial and material standards.

An improved GRA algorithm for teaching quality evaluation of college physical education based on the probabilistic simplified neutrosophic sets

With the emergence of various new teaching concepts and teaching models in colleges and universities, the original evaluation system can no longer fully meet the requirements of the current development of physical education curriculum teaching in colleges and universities. Thus, reducing the judgment and guidance of evaluation on physical education curriculum teaching shall result in the development of physical education curriculum teaching quality evaluation lagging behind the development of teaching and being in a passive position. Therefore, it is particularly important to establish a new evaluation standard system for the teaching quality of physical education courses. The teaching quality evaluation of college physical education (PE) is viewed as multiple attribute decision-making (MADM). In this paper, an enhanced probabilistic simplified neutrosophic grey relational analysis (PSN-GRA) method is designed for MADM. Then, in the environment of probabilistic simplified neutrophil set (PSNSs), the PSN-GRA method and CRITIC method are combined to rank the alternative schemes, and a numerical example of college physical education teaching quality evaluation proves the practicability of the new method and compares it with other methods. The results show that this method is simple, effective and simple in calculation.
