PENGEMBANGAN E-LKPD MODEL PROBLEM BASED LEARNING MENGGUNAKAN LIVEWORKSHEETS PADA MATERI NEGARA MAJU DAN NEGARA BERKEMBANG

This study aims to develop an Electronic Student Worksheets Problem Based Learning model using liveworksheets website material for developed and developing countries.. The research design used was the Educational Design Research model of Plomp & Nieveen using quantitative research methods. The results of material expert validation obtained average scores for each aspect are aspects of content feasibility 4 (good), aspects of concept correctness 4.2 (good), aspects of material suitability 4 (good), linguistic aspects 4.3 (very good), and aspects of PBL syntax conformity 4 (good). So that the average score of the overall aspect of the material expert is 4.1 (good) and the percentage of feasibility is 82% (very feasible). The results of media expert validation obtained the average score of each aspect is the linguistic aspect 4.2 (good), the presentation aspect 4 (good), and the graphic aspect 4.3 (very good). So that the average score of all aspects of media experts is 4.2 (good) and the percentage of eligibility is 83% (very feasible). The results of the geography teacher's assessment obtained an average score for each aspect is the aspect of subject matter 4.2 (good), the practicality aspect of E�LKPD 4.3 (very good), and the aspect of conformity of PBL syntax 4.3 (very good). So that the average score of the overall aspect of the geography teacher is 4.3 (very good) and 86% (very decent). Meanwhile, the results of small-scale student trials totaling 12 students obtained an overall average score of 4.3 (very good) and 86% (very feasible). The results of large-scale trials totaling 24 students obtained results of 4.3 (very good) and 87% (very feasible)
