One of the important topics in chemistry learning is the basic laws of chemistry. However in reality many students find them difficult to understand. Learning methods and teaching materials are among the causes of students difficulties in understanding the basic laws of chemistry. The purpose of this study was to develop a liveworksheet LKPD based on Problem Based Learning (PBL) on the basic laws of chemistry to improve critical thinking skills and student learning outcomes and to determine its feasibility. This development research used the Research and Development (R amp D) method with the ADDIE model. The ADDIE model has stages analysis design development implementation and evaluation. This study was conducted on 29 students in grades X of SMA. The results of the study were electronic worksheets (LKPD) on the basic laws of chemistry based on material and media validation tests field practitioner validation tests readability tests teacher responses and student responses. The expert validation test obtained an average score of 85.5% for media validation 85.7% for material validation and 93.5% for field practitioner validation. All three results were categorized as very valid. The readability test obtained an average score of 94.4% with the criterion of easy to understand. The results of teacher and student responses obtained average scores of 93.4% and 97.3% respectively with the criterion of very good. Based on these results it was concluded that the E-LKPD liveworksheet based on Problem Based Learning (PBL) on the basic laws of chemistry is suitable for use as teaching materials in the classroom.
