Pengembangan LKPD Berorientasi Assessment for Learning untuk Meningkatkan Keterampilan Berpikir Kritis Peserta Didik pada Materi Titrasi Asam Basa

Development of LKPD Oriented Assessment for Learning to Improve Students Critical Thinking Skills in Acid Base Titration Materials

Penelitian Pengembangan LKPD berorientasi afl bertujuan mengetahui kelayakan LKPD ditinjau dari aspek validitas, kepraktisan, dan keefektifan untuk meningkatkan keterampilan berpikir kritis pada Titrasi Asam Basa. Penelitian ini menggunakan model penelitian R&D yang mengacu pada Borg dan Gall. Instrumen penelitian untuk validitas meliputi lembar validasi. Kepraktisan LKPD ditinjau dari lembar observasi aktivitas peserta didik dan angket respon peserta didik. Keefektifan LKPD ditinjau dari tes keterampilan berpikir kritis. Hasil penelitian menunjukkan bahwa LKPD berorientasi assessment for learning pada materi titrasi asam basa dinyatakan layak. Ditinjau dari hasil validasi memperoleh skor modus sebesar 5 yang termasuk sangat valid pada aspek validitas isi dan konstruk. LKPD memenuhi kriteria kepraktisan didukung hasil aktivitas peserta didik yang relevan dengan pembelajaran pada pertemuan 1 dan 2 yaitu 90 % dan 96%. Didukung respon positif dengan persentase 83%-100% dengan kriteria sangat baik. LKPD memenuhi kriteria keefektifan ditinjau dari keterampilan berpikir kritis peserta didik mengalami peningkatan n-gain dengan persentase 100% peserta didik berada dalam kategori sedang dan tinggi.

AFL-oriented LKPD Development Research aims to determine the feasibility of LKPD in terms of the aspects of validity, practicality, and effectiveness to improve critical thinking skills in Acid-Base Titrations. This study used an R&D research model that refers to Borg and Gall. The research instrument for validity includes a validation sheet. The practicality of LKPD was seen from the student activity observation sheet and student response questionnaire. The effectiveness of LKPD was seen from the test of critical thinking skills. The results showed that the assessment for learning oriented LKPD on acid-base titration material was declared feasible. Judging from the validation results, a mode score of 5 obtained which was very valid in terms of content and construct validity. LKPD meets practicality criteria supported by the results of student activities that are relevant to learning at meetings 1 and 2, namely 90% and 96%. Supported by a positive response with a percentage of 83% -100% with very good criteria. Student worksheets fulfilling the effectiveness criteria in terms of students critical thinking skills experience an increase in n-gain with a percentage of 100% of students being in the medium and high categories.
