Abstract
At present, education is directed towards forming students who have the competence of the industrial revolution 4.0, one of which has critical thinking skills. This article reports the results of research in developing a Physics student worksheet (LKPD) with the STEM (Science, Technology,
Engineering, and Mathematics) approach, which is valid, practical and effective for enhancing students' critical thinking. Research and development (R&D) with the Borg & Gall model has been used in this study, where the stages are initial research and information gathering, planning, developing initial product formats, and initial trials of products. The object of research is the Physics student worksheet based on the STEM approach. Data were collected using validation sheets, practicality test sheets and effectiveness test sheets. The effectiveness of the product was tested using a critical thinking ability test and an observation sheet of students' critical thinking processes. Data analysis uses analysis techniques for the validity, practicality and effectiveness of LKPD. The research results obtained are; firstly, the validity of the Physics student worksheet based on the STEM approach is 0.88 and this value is included in the valid category. Secondly, the practicality for the use of Physics student worksheets by teachers and students respectively 91.44 and 84.14. This value shows the Physics student worksheet is very practical. Besides that, the use of a Physics student worksheet based on the STEM approach is effective to enhance students critical thinking.
