Development of Interactive Worksheets Based on Problem Based Learning Assisted by iSpring Suite for Atomic Structure Material for High School Phase E

Abstract

Education in the modern era refers to innovative learning methods and demands learner-centered learning. This research aims to develop interactive student worksheets based on Problem-Based Learning assisted by iSpring Suite as an effort to use innovative teaching materials and encourage active student engagement in the learning process. The purpose of this research is to produce valid and practical interactive worksheet based on Problem-Based Learning assisted by iSpring Suite for atomic structure material in high school phase E. This research was conducted using the 4D (four-D) research model. The subjects in this study were 3 lecturers from the Chemistry Department of FMIPA UNP, 2 chemistry teachers, and students from class X Phase E at SMA N 15 Padang. The instruments used in this research were validity sheets and practicality questionnaire sheets. The data processing results from the validity test used Aiken’s V formula, while the practicality data was obtained by determining the practicality percentage from the comparison of the respondents' total scores to the maximum score. The results of the validity test analysis showed an average value of 0.87 in the valid category. Meanwhile, the practicality test results from the teachers showed a percentage of 91% in the very practical category, and the practicality test results from the students showed a percentage of 87.25% in the very practical category. Based on the results of the conducted research, it can be concluded that the interactive LKPD based on Problem-Based Learning assisted by iSpring Suite for atomic structure material in high school phase E is valid and very practical.
