Pengembangan LAPD untuk Meningkatkan Kemampuan Berpikir Analisis pada Submateri Faktor- faktor yang Mempengaruhi Laju Reaksi melalui Model Pembelajaran Inkuiri

Development of LAPD to Improve Analytical Thinking Skills on the Submaterial of Factors Affecting the Reaction Rate through the Inquiry Learning Model

Kemampuan berpikir analisis sangat krusial dalam meningkatkan kualitas pendidikan di Indonesia. Penelitian ini bertujuan untuk mengembangkan lembar aktivitas peserta didik atau LAPD untuk meningkatkan kemampuan berpikir analisis melalui model pembelajaran inkuiri pada submateri faktor-faktor yang mempengaruhi laju reaksi yang layak mengacu pada tiga aspek yaitu validitas, kepraktisan, dan keefektifan. Aspek validitas ditinjau dari validitas isi dan konstruk. Penelitian ini menerapkan pendekatan model ADDIE (Analyze, Design, Develop, Implement, Evaluate), namun fokusnya terbatas pada tahap Develop. Responden keseluruhan 30 peserta didik kelas XI-6 SMA Negeri 1 Sidayu Gresik. Hasil penelitian menunjukkan bahwa kelayakan dari aspek validitas diperoleh hasil pada kriteria isi dan konstruk telah memperoleh modus penilaian dari tiga validator minimal 4. Kelayakan dari aspek kepraktisan ditinjau berdasarkan hasil angket respons peserta didik sebesar 98% dengan kategori praktis dan didukung oleh hasil persentase observasi aktivitas peserta didik sebesar 95%. Kelayakan dari aspek keefektifan diperoleh dari hasil tes kemampuan berpikir analisis peserta didik yang diuji menggunakan uji Wilcoxon Signed Ranks. Berdasarkan uji tersebut, diperoleh hasil p-value (1-tailed) = 0,000 (<0,05). Hal ini menunjukkan bahwa H0 ditolak dan Ha diterima yang menyatakan rata-rata nilai posttest lebih besar daripada rata-rata nilai pretest, artinya terdapat peningkatan skor yang signifikan antara sebelum dan sesudah penggunaan LAPD.

Analytical thinking skills are crucial in improving the quality of education in Indonesia. This research aims to develop students’ activity sheets or LAPD to improve analytical thinking skills through an inquiry learning model on the submaterial of factors that affect the reaction rate that is feasible referring to three aspects namely validity, practicality, and effectiveness. The validity aspect is reviewed from content and construct validity. This research applies the ADDIE model approach (Analyze, Design, Develop, Implement, Evaluate), but the focus is limited to the Develop stage. The overall respondents were 30 students of class XI-6 SMA Negeri 1 Sidayu Gresik. The results showed that the feasibility of the validity aspect obtained results in the content and construct criteria had obtained an assessment mode from three validators of at least 4. The feasibility of the practicality aspect is based on the results of the students’ response questionnaire of 98% with the practical category and is supported by the results of the percentage of students’ activity observations of 95%. The feasibility of the effectiveness aspect is obtained from the results of the students analytical thinking ability test which is tested using the Wilcoxon Signed Ranks test. Based on this test, the results obtained p-value (1-tailed) = 0.000 (<0.05). This shows that H0 is rejected and Ha is accepted which states that the average posttest score is greater than the average pretest score, meaning that there is a significant increase in scores between before and after the use of LAPD.
