Pengembangan Lkpd Inkuiri Berbantuan Internet Assisted Learning untuk Melatihkan Keterampilan Berpikir Kritis pada Submateri Laju Reaksi

Development of Student Worksheet Based on Inquiry and Internet Assisted Learning to Practice Critical Thinking Skills in Submateries of Reaction Rates

Penelitian ini bertujuan untuk mengetahui kelayakan LKS Inkuiri siswa berbasis Internet Assisted Learning pada materi Laju Reaksi Praktik Keterampilan Berpikir Kritis siswa kelas XI SMA. Rancangan penelitian pengembangan menggunakan metode 4-D (Define, Design, Develop, dan Dissiminate). Penelitian ini hanyasampai pada tahap pengembangan. Uji coba dilakukan terhadap 24 siswa kelas XI SMA yang belum mendapatkan materi tentang laju reaksi pada 9-20 November 2020. Instrumen penelitian terdiri dari lembar telaah lembar validasi, lembar angket respon siswa, lembar tes pengetahuan, dan lembar tes keterampilan berpikir kritis. Hasil penelitian menunjukkan bahwa LKS sangat layak berdasarkan penilaian validator dan respon siswa ≥ 81% serta mencapai nilai ≥ 75 sesuai kriteria ketuntasan belajar minimal. Penilaian validator berdasarkan kriteria kriteria isi, bahasa, penyajian, dan grafik menunjukkan persentase 98.6%, 86.4%, 85,4%, and 100% dalam kategori sangat valid. Respon siswa menunjukkan penilaian respon positif berdasarkan kriteria kelayakan isi, bahasa, presentasi, dan grafik menunjukkan kriteria persentase isi 91.8%, bahasa 81.7%, presentasi 85%, dan grafik 96.7%. Hasil tes pengetahuan diperoleh skor n-gain 0.85 dengan kategori sangat tinggi. Hasil tes keterampilan berpikir kreatif diperoleh skor n-gain sebesar 0.795 dengan kategori sangat tinggi. Hal ini menunjukkan bahwa LKPD yang dikembangkan sudah efektif

This study aims to determine the feasibility based of Inquiry student worksheets based on Internet Assisted Learning in the reaction rate submaterial to practice critical thinking skills of class XI SMA students. The development research design uses the 4-D method (Define, Design, Develop, and Dissiminate). In this research it is up to the development stage. The trial was carried out on 24 high school class XI students who had not received material on the reaction rate on November 9-20 2020. The research instrument consisted of a review sheet, a validation sheet, a student response questionnaire, a knowledge test sheet, and a critical thinking skill test sheet. The results showed that the student worksheet was very feasible based on the assessment of the validator and student responses of ≥ 81% and achieving a value of ≥ 75 according to the criteria for minimum learning completeness. The validator's assessment based on the eligibility of the content, language, presentation, and graphic criteria showed the percentage of 98.6%, 86.4%, 85,4%, and 100% in the very valid category. Student response shows a positive response assessment based on the eligibility of the content, language, presentation, and graphic criteria showed the percentage criteria of content is 91.8% , language is 81.7%, presentation is 85%, and graphic 96.7%. The results of the knowledge test obtained an n-gain score of 0.85 in the very high category. The results of the creative thinking skills test obtained an n-gain score of 0.795 in the very high category. This shows that the LKPD is effective.
