Abstract

This research aims to develop an assisted digital student worksheet (LKPD-D). liveworksheet on students' critical thinking skills and problem solving abilities which are assessed in terms of validity, practicality and effectiveness. The research method used is development research (Research and Development) with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The subjects of this research were class IX students at SMP Negeri 2 Bungku Selatan. The overall score validation from the validator shows a validity level of 90%, both of which are included in the valid category. The response of teachers and students to the LKPD was 95% for teachers, while the student response questionnaire was 87.21%, both of which were in the very practical category. The effectiveness of Digital LKPD products in improving critical thinking skills and problem solving abilities is measured by the N-Gain percentage score and Effect Size. The N-Gain percentage in critical thinking skills obtained an overall score of 56.28% with a fairly effective interpretation category, while the effect size value was 1.23 with a very large effect interpretation, which means that the LKPD had a significant impact on improving students' critical thinking skills while the value The N-Gain percentage of problem solving ability is 56.42% with a fairly effective interpretation category, while the effect size value is 1.37 with a large effect interpretation, which means that the LKPD has a significant impact on increasing students' problem solving abilities. These results indicate that the Digital LKPD is assisted liveworksheet valid, practical and effective.
