Pengembangan e-LKPD Liveworksheets Berorientasi Problem Based Learning Untuk Melatihkan Keterampilan Berpikir Kritis Peserta Didik Pada Materi Hidrolisis Garam

Development of Electronic Student Worksheets Oriented Problem Based Learning to Train Students Critical Thinking Skills on Salt Hydrolysis Material

Tujuan dari penelitian ini adalah memproleh e-LKPD liveworksheets berorientasi problem based learning yang layak digunakan untuk melatihkan keterampilan berpikir kritis peserta didik pada materi hidrolisis garam. Kelayakan e-LKPD ditinjau dari tiga aspek, yaitu kebaikan, kepraktisan, dan keefektifan. Penelitian ini menggunakan metode 4D yang dibatasi sampai tahap develop dengan model pengembangan Thiagarajan. Uji coba terbatas dilaksanakan di kelas XI-12 SMAN 1 Sidoarjo dengan 37 peserta didik. Data hasil penelitian menunjukkan bahwa (1) e-LKPD liveworksheets berorientasi problem based learning dinyatakan valid ditunjukkan dengan modus validitas isi dan validitas konstruk sebesar 5 dengan kategori sangat baik, (2) e-LKPD liveworksheets berorientasi problem based learning dinyatakan praktis ditunjukkan dengan rata-rata hasil angket respon peserta didik didukung oleh hasil observasi aktivitas peserta didik sebesar 94% dengan kategori sangat baik, (3) e-LKPD liveworksheets berorientasi problem based learning dinyatakan efektif berdasarkan nilai rata-rata posttest lebih tinggi dibandingkan pretest dengan N-Gain Score 0.76 dengan kategori tinggi pada keterampilan berpikir kritis dan 0.73 dengan kategori tinggi pada kognitif. Serta hasil uji paired sample t-test dengan memberikan nilai signifikansi 0,000, menandakan adanya perbedaan signifikan antara nilai pretest dan posttest.

This research aims to obtain problem-based learning-oriented e-worksheets that are feasible to train students' critical thinking skills on salt hydrolysis material. The feasibility of e-worksheets is reviewed from three aspects: validity, practicality, and effectiveness. This research uses the 4D method limited to the development stage with the Thiagarajan development model. The limited trial was conducted in class XI-12 State High School 1 Sidoarjo with 37 students. The research data showed that (1) problem-based learning-oriented e-worksheets are declared valid, indicated by the mode of content content validity and construct validity of 5 with very good categories, (2) The e-worksheets are declared practical, indicated by the average results of student response questionnaires of 94% with a very practice category supported by the results of student activity observations, (3) problem-based learning-oriented e-worksheets are declared effective based on the average value of the posttest higher than the pretest with an N-Gain Score of 0.76 with a high category on critical thinking skills and 0.73 with a high category on cognitive. The results of the paired sample t-test were given a significance value of 0.000, indicating a significant difference between pretest and posttest scores.
