Pengembangan LKPD Model Project Based Learning Berbasis Android untuk Melatihkan Keterampilan Berpikir Kritis Peserta Didik SMA 

Development of Android-Based Project-Based Learning Model LKPD to Train Critical Thinking Skills of High School Students

Penelitian ini mengembangkan LKPD model Project Based Learning berbasis Android untuk melatihkan keterampilan berpikir kritis siswa SMA dalam topik aliran energi, rantai makanan, dan jaring-jaring makanan. Menggunakan model ADDIE, penelitian dilakukan di kelas X SMAN 1 Kuripan dengan 30 siswa saat uji coba terbatas dan 60 siswa saat uji coba luas. Instrumen penelitian meliputi validasi oleh tiga validator, observasi keterlaksanaan dan aktivitas siswa, angket respon, serta tes berpikir kritis. Hasil penelitian menunjukkan LKPD sangat valid, praktis, dan efektif: validitasnya sangat valid dengan ICC mencapai almost perfect agreement, keterlaksanaannya mencapai 100% dengan aktivitas siswa ≥ 90%, efektivitasnya terbukti dengan N-gain kategori sedang dan tinggi serta hasil uji t-test yang signifikan (p < 0,05) dan respon siswa juga sangat positif (≥ 90%). Berdasarkan hasil ini, LKPD model PjBL berbasis Android dinyatakan layak digunakan untuk melatihkan keterampilan berpikir kritis siswa SMA.

This research developed an Android-based Project Based Learning (PjBL) worksheet (LKPD) to train the critical thinking skills of high school students on the topics of energy flow, food chains, and food webs. Using the ADDIE model, the research was conducted in class X of SMAN 1 Kuripan with 30 students during the limited trial and 60 students during the extensive trial. Research instruments included validation by three validators, observation of LKPD implementation and student activities, response questionnaires, and critical thinking tests. The results showed that the LKPD was very valid, practical, and effective: its validity was very high with ICC reaching almost perfect agreement, its implementation reached 100% with student activity ≥ 90%, its effectiveness was proven with N-gain in the medium and high categories, and the t-test results were significant (p < 0.05) with very positive student responses (≥ 90%). Based on these results, the Android-based PjBL LKPD was declared feasible for use in training the critical thinking skills of high school students.
