Inovasi model proyek based learning berbasis sains, teknologi, teknik, dan matematika terhadap penalaran matematis dan motivasi belajar siswa sma. Tingkatkan penalaran matematis & motivasi belajar siswa SMA. Penelitian ini inovasi model PjBL berbasis STEM, terbukti signifikan dongkrak kemampuan & semangat belajar.
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). Metode yang digunakan pada penelitian ini adalah Pre-Experimental one-Group pretest-posttest design. Waktu penelitian ini dilakukan semester genap. Jumlah populasi penelitian ini adalah 86 siswa dan sampel dipilih 1 kelas dari 3 kelas secara acak diperoleh sebanyak 28 siswa. Instrument pengumpulan data terdiri atas instrument tes dan non test. Instrument test dalam bentuk uraian untuk mengukur kemampuan penalaran matematis. Sedangkan instrument non test merupakan angket motivasi belajar dengan menggunakan Skala Likert. Hasil penelitian menunjukan bahwa (1) terdapat perbedaan penalaran matematis siswa secara signifikan sebelum dan sesudah perlakuan model pembelajaran PjBL berbasis STEM; (2) terdapat perbedaan motivasi belajar siswa secara signifikan sebelum dan sesudah perlakuan model Proyek Based Learning (PjBL) berbasis sains, teknologi, teknik, dan matematika (STEM). Bagi peneliti lain, menjadikan hasil penelitian ini sebagai pedoman dan bahan pertimbangan dalam penelitian selanjutnya yang relevan.
The study "Inovasi Model Proyek Based Learning Berbasis Sains, Teknologi, Teknik, Dan Matematika Terhadap Penalaran Matematis Dan Motivasi Belajar Siswa SMA" addresses a critical issue in mathematics education: the underdeveloped mathematical reasoning skills and low learning motivation among high school students. The authors effectively establish the problem through observational findings at SMA Negeri 8 Kota Tidore Kepulauan, noting students' difficulties in analyzing information, their passive learning approach, and a general reluctance to engage critically with mathematical problems. This foundational issue highlights the necessity for pedagogical innovation, which the research attempts to provide through the implementation of a Project-Based Learning (PjBL) model integrated with Science, Technology, Engineering, and Mathematics (STEM) principles. The clear objectives, focusing on assessing changes in mathematical reasoning and learning motivation post-intervention, set a focused direction for the investigation. Methodologically, the study employs a Pre-Experimental one-Group pretest-posttest design, a common approach for evaluating the initial impact of an intervention. This design allowed for a direct comparison of the target variables within the same group of students (n=28) before and after exposure to the PjBL-STEM model. The selection of a single class via random sampling from a total population of 86 students provides some basis for the sample's representation, though the absence of a control group inherently limits the generalizability and attribution of observed changes solely to the intervention. Data collection instruments, comprising essay tests for mathematical reasoning and a Likert scale questionnaire for learning motivation, appear appropriate and systematically chosen to measure the intended outcomes. The transparent reporting of the design and instrumentation contributes positively to the study's clarity. The findings robustly indicate that the PjBL-STEM model significantly improved both mathematical reasoning and learning motivation among the participating students. The statistically significant differences observed between pre- and post-test scores for both variables suggest that this innovative pedagogical approach holds considerable promise for addressing the identified educational challenges. This outcome provides valuable empirical support for integrating STEM concepts within a PjBL framework, offering a practical pathway for educators to foster deeper engagement and cognitive development. While the pre-experimental design means causality cannot be definitively established, the results strongly advocate for further exploration. The recommendation for future researchers to use these findings as a guide is pertinent, encouraging more rigorous experimental designs, larger sample sizes, and possibly longitudinal studies to further validate and explore the long-term impact and transferability of this promising educational model.
