Pengembangan Lkpd Berbasis Problem Based Learning Dengan Memanfaatkan Aplikasi Padlet Untuk Meningkatkan Prestasi Belajar Siswa Di Sma Negeri 1 Kradenan
This study aims to determine: 1) The feasibility of Problem-Based Learning-based LKPD learning media by utilizing the Padlet application in Economics for class X students at SMA Negeri 1 Kradenan. 2) The use of Problem-Based Learning-based LKPD learning media by utilizing the Padlet application can improve student learning achievement in Economics subject in class X at SMA Negeri 1 Kradenan. This research is a type of development research or Research and Development (R&D) with the ADDIE development model. Data collection techniques in this development research are through observation, questionnaires and tests. The type of data in this study is to use quantitative and qualitative data. The results of the study show that there are five stages in making Problem Based Learning worksheets, namely Analysis, Design, Development, Implementation, and Evaluation. The feasibility of LKPD learning media based on Problem Based Learning based on the assessment: 1) Material Expert 1 obtained an average score of 100% which was included in the very feasible category, 2) Material Expert 2 obtained an average score of 91.92% which was included in the very feasible category, 3) Media Expert obtained an average score of 87.5% which was included in the very feasible category. Based on the results of the study, the media effectiveness trial data after the pre-test and post-test for class X students at SMA Negeri 1 Kradenan obtained an average pre-test of 37.27% and a post-test of 70.80% for the control class, while a pre-test average of 38.48% and a post-test of 90.91% for the experimental class were obtained. From the learning outcomes data that was tested also had a significant difference because Sig. (2-tailed) has a value of 0.000 less than 0.05. So it can be concluded that there is a difference between the pre-test (before using Problem Based Learning-based LKPD learning media) and post-test (after using Problem Based Learning-based LKPD learning media)
