Pengembangan LAPD (Lembar Aktivitas Peserta Didik) Berbasis Inkuiri Terbimbing untuk Meningkatkan Hasil Belajar Peserta Didik Kelas XI SMA pada Materi Kesetimbangan Kimia

Development of LAPD (Student Activity Sheet) Based on Guided Inquiry to Improve Learning Outcomes of Grade XI High School Students on Chemical Equilibrium Material

Penelitian ini bertujuan untuk mengembangkan Lembar Aktivitas Peserta Didik (LAPD) berbasis inkuiri terbimbing pada materi kesetimbangan kimia untuk meningkatkan hasil belajar peserta didik kelas XI SMA. Pembelajaran kimia, khususnya pada topik kesetimbangan kimia sub materi faktor-faktor yang mempengaruhi arah pergeseran kesetimbangan kimia, sering kali dianggap abstrak dan sulit dipahami oleh peserta didik, sehingga dibutuhkan media pembelajaran yang mampu memfasilitasi proses berpikir kritis dan pemahaman konseptual. Inkuiri terbimbing dipilih sebagai pendekatan pembelajaran karena memberikan keseimbangan antara arahan guru dan eksplorasi mandiri oleh peserta didik. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan mengacu pada model pengembangan 4-D (Define, Design, Develop, dan Disseminate) dan dibatasi hingga tahap Develop saja. Populasi dalam penelitian ini adalah kelas XI SMA IPIEMS Surabaya. Hasil validasi LAPD dari ketiga validator memperoleh skor modus sebesar 5 yang berarti LAPD layak dengan kategori sangat valid. Hasil persentase respon peserta didik yang diperoleh 96% yang dinyatakan sangat praktis. Hasil belajar peserta didik dinyatakan tuntas apabila mencapai nilai ≥ 80. Berdasarkan hasil posttest, menunjukkan persentase ketuntasan sebesar 88,5%. Persentase ini menunjukkan bahwa ketuntasan klasikal telah tercapai, sehingga dapat disimpulkan bahwa pembelajaran berbasis inkuiri terbimbing efektif dalam meningkatkan hasil belajar peserta didik.

This study aims to develop a guided inquiry-based Learner Activity Sheet on chemical equilibrium material to improve the learning outcomes of class XI high school students. Chemistry learning, especially on the topic of chemical equilibrium sub-material factors that affect the direction of chemical equilibrium shifts, is often considered abstract and difficult for students to understand, so learning media is needed that can facilitate critical thinking processes and conceptual understanding. Guided inquiry was chosen as a learning approach because it provides a balance between teacher direction and independent exploration by students. The research method used is Research and Development (R&D) with reference to the 4-D development model (Define, Design, Develop, and Disseminate) and limited to the Develop stage only. The population in this study was class XI of IPIEMS Surabaya High School The results of the validation of the Learner Activity Sheet from the three validators obtained a mode score of 5 which means that the Learner Activity Sheet is feasible with a very valid category. The percentage of students' responses obtained was 96% which was declared very practical. The learning outcomes of students are declared complete if they reach a score ≥ 80. Based on the posttest results, the percentage of completeness is 88.5%. This percentage shows that classical completeness has been achieved, so it can be concluded that guided inquiry-based learning is effective in improving student learning outcomes.
