Abstract

This research aims to describe the validity of the Electronic Learner Activity Sheet (E-LAPD) for reaction rate to improve critical thinking skills with the 7-E learning cycle learning model developed. The development model in this research is ADDIE with four stages Analyze, Design, Development, and Evaluate. The validation results were analyzed based on the mode in each aspect. Based on the validation results, it was found that the developed reaction rate E-LAPD has a good category with a score of 3 on the content validity aspect and a good category with a score of 3 on construct validity. Furthermore, reaction rate electronic learner activity sheet can be used in the learning process in the classroom to determine the practically and effectiveness of the developed reaction rate electronic worksheet

Abstract

Penelitian ini bertujuan untuk mengetahui validitas Lembar Kerja Peserta Didik Elektronik (E-LKPD) problem based learning berbasis multipel representasi kimia  untuk meningkatkan keterampilan berpikir kritis peserta didik pada submateri faktor laju reaksi. Model pengembangan dalam penelitian ini adalah ADDIE dengan empat tahap yaitu Analyze (Analisis), Design (Desain), Development (Pengembangan), dan Evaluate (Evaluasi). Hasil validasi dianalisis berdasarkan modus pada setiap aspek. Berdasarkan hasil validasi diperoleh bahwa E-LKPD PBL berbasis multipel representasi kimia yang dikembangkan memiliki kategori baik dengan skor 3 pada aspek validitas isi dan kategori baik dengan skor 3 pada aspek validitas konstruk. Selanjutnya, E-LKPD yang telah valid dapat digunakan dalam proses pembelajaran di kelas guna menilai tingkat kepraktisan dan keefektifan dari E-LKPD yang telah dikembangkan.
