The Development of Electronic Worksheets (E-LKPD) Argumentation Based on TPS Cooperative Learning Model on Chemical Equilibrium Material

The purpose of this study was to describe the feasibility of argumentation E-LKPD based on the TPS cooperative learning model on chemical equilibrium material. The feasibility of E-LKPD can be verified from validity, practicality and effectiveness. The method used in this research is research and development (R&D) with the ADDIE development model. The research trial was conducted in January 2024 on 16 students of SMAN 16 Surabaya who had received chemical equilibrium material. Based on the results of, it shows that the validity of E-LKPD is declared valid in terms of the acquisition of the validation sheet score with a mode of 3 valid categories. The practicality of E-LKPD is declared practical in terms of the results of the student response questionnaire with a percentage of 90.4% with very good category criteria. The effectiveness of E-LKPD is declared effective in terms of the analysis of the results of the t-test with a significance level of 5%, obtained t count> t table of 3.59> 1.746 so that Ho is rejected and Ha is accepted, the n-gain score of the chemical equilibrium cognitive test question is 0.90 with a high category, and the n-gain score of the students' argumentation skills is 0.90 with a high category. The n-gain score of the students' argumentation skills is 0.715 with high criteria. Based on these results, it can be concluded that the argumentation E-LKPD based on the developed TPS cooperative learning model on chemical equilibrium material is feasible to use.
