Abstract
The development of 21st-century technology, education has shifted to a more interactive and student-based approach, focusing on the development of critical thinking, collaboration, communication, and creativity (4C) competencies. This research aims to design a Student E-Worksheet integrated with the Problem Based Learning (PBL) model to improve students' critical thinking skills in physics learning, especially in global warming materials. The subject of the study is a product validity test by 3 lecturers who are only interested in material and appearance. Meanwhile, the object of the research is E-student worksheet integrated PBL to facilitate critical thinking skills. The research method used is development research with the ADDIE model, which includes analysis, design, development, implementation, and evaluation. The validity of the E-student worksheet was measured using the Likert scale, showing a result of 92% with a very valid category. The development results show that E-student worksheet can increase student involvement and independence in the learning process. Thus, this PBL-integrated E-student worksheet is expected to be an effective and interesting learning resource, as well as help students in understanding physics concepts
