Pengembangan Lembar Kerja Peserta Didik (LKPD) Berbasis Assessment for Learning Pada Materi Kesetimbangan Kimia Untuk Meningkatkan Keterampilan Proses Sains Peserta Didik

Development Of Student Worksheets (LKPD) Based Assessment for Learning On Chemical Balance Materials To Improve Student Process Science Skills

Penelitian ini bertujuan untuk memperoleh LKPD berbasis Assessment for learning yang dapat meningkatkan keterampilan proses sains pada materi kesetimbangan kimia. Metode penelitian yang digunakan dalam penelitian ini adalah Research and Development (R&D) model ADDIE dengan lima tahap yaitu: 1) analisis; (2) perancangan; (3) pengembangan; (4) implementasi; dan (5) evaluasi. Data diperoleh dari skor validitas berdasarkan modus skor praktikalitas yang diperoleh dari hasil angket respon peserta didik, dan skor efektivitas yang diperoleh dari hasil pretest dan posttest yang dianalisis dengan uji statistik parametrik menggunakan uji one sample t-test. Berdasarkan hasil penelitian, modus validitas diperoleh skor 5 pada setiap aspek, skor praktikalitas sebesar 90,7% dan p-value uji t diperoleh 0,000 sehingga LKPD berbasis Assessment for learning yang dikembangkan dapat dianggap layak untuk meningkatkan keterampilan proses sains peserta didik pada materi kesetimbangan kimia. Adanya penilaian pembelajaran dan umpan balik yang diberikan dalam LKPD berbasis Assessment for learning menjadikan peserta didik aktif dan dapat meningkatkan keterampilan proses sains peserta didik pada materi kesetimbangan kimia.

This research aims to develop Student Worksheets (LKPD) based on assessment for learning that can enhance science process skills in chemical equilibrium material. The research method used in this study is Research and Development (R&D) following the ADDIE model with five stages: 1) analysis; (2) design; (3) development; (4) implementation; and (5) evaluation. Data were obtained from validity scores based on the mode of practicality scores derived from student response questionnaires, and effectiveness scores obtained from pretest and posttest results analyzed using parametric statistical tests, specifically the one-sample t-test. Based on the research results, the validity mode obtained a score of 5 in every aspect, the practicality score was 90.7%, and the t-test p-value was 0.000, indicating that the developed assessment for learning-based LKPD can be considered suitable for improving students' science process skills in chemical equilibrium material. The presence of learning assessments and feedback provided in the assessment for learning-based LKPD makes students active and can enhance their science process skills in chemical equilibrium material.
