This study aims to develop a PBL based LivePuzz E-Student Worksheet (E-LKPD) on the topic of Relations and Functions to enhance the problem-solving skills of 8th-grade students, ensuring the product is valid, practical, and effective.
This learning medium was developed using the Liveworksheets and Edpuzzle websites to create an engaging learning experience and support student involvement in the learning process.
The research method employed was Research and Development (R&D), utilizing the ADDIE development model, which consists of the stages: Analysis, Design, Development, Implementation, and Evaluation. Product trials were conducted with 8th-grade students at MTsN 08 Magetan, involving 21 participants. Data collection techniques included observation, interviews, validation questionnaires for subject matter and media experts, user response questionnaires (for teachers and students), and learning outcome tests.
The development research results indicate that the validity level of the learning medium reached 92% according to subject matter experts (classified as "very valid"), while media experts rated it at 79% (classified as "valid"). Furthermore, practicality test results via mathematics teacher response questionnaires showed a score of 90%, and the average student response reached 96%; both results fall into the "very practical" category. Effectiveness test results demonstrate that the medium enhances problem-solving skills, evidenced by a classical mastery level of 85.71% in student learning outcomes (post-test). In conclusion, this PBL-based LivePuzz E-LKPD is deemed valid, practical, and effective for use. The implication of this study is that it contributes to the availability of interactive digital learning media innovations that integrate contextual problems to foster students' independent thinking.
