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.

Penalaran matematis merupakan kesanggupan seseorang dalam menyusun bukti, memberi penjelasan dan mengambil sebuah kesimpulan dari permasalahan yang dihadapi. Berdasarkan hasil observasi yang telah dilakukan di SMA Negeri 8 Kota Tidore Kepulauan (TIKEP) menunjukkan bahwa proses pembelajaran dan soal-soal evaluasi yang diberikan belum berorientasi untuk mengembangkan kemampuan penalaran matematika. Hal ini mengakibatkan rendahnya kemampuan penalaran matematika siswa. Siswa kesulitan menganalisis informasi yang ada, cenderung menerima apa adanya informasi yang disampaikan maupun yang tertulis dalam buku, dan pasif dalam mengajukan pertanyaan-pertanyaan maupun menjawab pertanyaan dari permasalahan yang diajukan guru. Faktor lain yang dapat mempengaruhi kemampuan penalaran matematika siswa masih rendah diakibatkan karena kurangnya motivasi belajar siswa. Tujuan penelitian ini adalah (1) mengetahui perbedaan penalaran matematis siswa kelas XI SMA Negeri 8 Kota Tidore Kepulauan sebelum dan sesudah perlakuan model pembelajaran PjBL berbasis STEM; (2) mendeskripsikan motivasi belajar siswa kelas XI SMA Negeri 8 Kota Tidore Kepulauan sebelum dan sesudah perlakuan model Proyek Based Learning (PjBL) berbasis sains, teknologi, teknik, dan matematika (STEM).
