Abstract

Mathematical representation ability is one of the expected abilities in learning mathematics in class. Very mathematical representation ability It is important for students to be able to make meaningful connections between concepts mathematics or between concepts and other fields or with life or environment around students. This research is important because it can analyze student representation abilities for students who have high, medium or low self efficacy to make it easier for teachers to apply appropriate learning methods. The aims of this research are (1) to analyze the influence of self-efficacy on students' mathematical representational abilities; (2) analyzing self-efficacy (high, medium and low) on the mathematical representation abilities of Tidore Islands City State High School/Vocational School students who implement the Independent Learning Curriculum. This research method is descriptive-quantitative with the type of research being causal survey research. Determination of the sample using random sampling techniques. The data collection techniques used were tests and questionnaires. The data analysis used is descriptive and inferential analysis. The findings of this research show that there is a significant influence of self-efficacy on students' mathematical representational abilities. The representative mathematical abilities of students for students who have high, medium and low self-efficacy results vary between one student and another.

Abstract

Penelitian ini mengembangkan model pembelajaran tolak peluru gaya ortodoks melalui modifikasi alat bantu berupa peluru kayu untuk meningkatkan motivasi dan keterampilan siswa. Latar belakang penelitian adalah keterbatasan sarana pembelajaran, khususnya peluru standar yang terlalu berat bagi siswa SMP. Metode yang digunakan adalah penelitian dan pengembangan (R&D) dengan tahapan analisis kebutuhan, pengembangan produk awal, uji coba skala kecil, revisi, uji coba skala besar, dan produk akhir. Data diperoleh melalui kuesioner dan observasi psikomotor, dianalisis secara deskriptif persentase. Hasil menunjukkan uji coba skala kecil memperoleh skor 66,4% (kategori baik) dan uji coba skala besar 80,3% (kategori baik). Siswa merasa lebih percaya diri, tidak takut, dan lebih antusias dalam pembelajaran. Temuan ini menunjukkan modifikasi peluru kayu dapat mengatasi keterbatasan fasilitas dan meningkatkan kualitas pembelajaran tolak peluru. Disimpulkan bahwa model ini efektif dan layak digunakan pada pembelajaran atletik di SMP.   Orthodox shot put learning model with wooden shot modification for junior high school students   Abstract: This study develops an orthodox shot put learning model through the modification of a wooden shot to enhance students’ motivation and skills. The research was driven by limited learning facilities, particularly the standard shot, which is too heavy for junior high school students. A research and development (R&D) approach was employed, involving needs analysis, initial product development, small-scale trials, revisions, large-scale trials, and final product creation. Data were collected using questionnaires and psychomotor observations, then analyzed descriptively. The small-scale trial scored 66.4% (good category), while the large-scale trial achieved 80.3% (good category). Students reported greater confidence, reduced fear, and increased enthusiasm during learning activities. These findings indicate that wooden shot modification effectively addresses facility limitations and improves the quality of shot put learning. It is concluded that the model is effective and feasible for athletic instruction in junior high schools.

Abstract

This study aims to compare underhand passing skills in volleyball using a real ball and a modified plastic ball. The benefits of this study are for physical education teachers in developing learning innovations using modified plastic balls to improve underhand passing skills in volleyball. It is hoped that this will help students improve their ability to perform underhand passing skills better. This study is a comparative study using a survey method. Data collection used an underhand passing test using a real volleyball and a modified plastic ball. This study was conducted on 10th-grade students of SMK Negeri 5 West Halmahera. The population was all 73 students of SMK Negeri 5 West Halmahera, with a sample size of 12 students. The variable in this study was a single variable, namely underhand passing skills of SMK Negeri 5 West Halmahera students. In this study, differences between male and female students were not considered. The analysis technique used was the t-test.The results of this study can be concluded that the skill of passing under volleyball using a modified plastic ball is more effective or makes it easier for class X students of SMK Negeri 5 West Halmahera to master the basic technical skills of passing under. This can be shown from the results of the hypothesis test that between the total score (%) of passing under using a real volleyball and the total score (%) of passing onions using a modified plastic ball. From the test results, the t-count price was obtained at -5.28, while from the t-table it was obtained at 2.10 (attached data). It turns out that the t-count price is smaller than the t-table, or the t-count price is outside the Ho acceptance area so it can be concluded that H0 is rejected and H1 is accepted.
