The validity and practicality of the student worksheet using STEM-based multiple representations in physics learning

The objective of this research was to produce a valid and practical student worksheet using Science Technology Engineering and Mathematics (STEM)-based multiple representations and integrated with twenty first century learning in vibration and wave topic. This research used Research and Development (R & D) method by following 4-D model steps. 15 sample students of grade XI were taken with random sampling. Research instruments were validation sheets, student worksheet implementation observation sheets, and questionnaires. Data were analyzed descriptively and qualitatively. The result showed that the student worksheet by using STEM approach based on integrated multiple representations and integrated with twenty first century learning was: 1) valid by content with average score of 85.41 and valid by construct with average score of 83.88; 2) practical to use in vibrations and waves learning materials and it was shown by average student worksheet implementation by above 80% and 86.66% positive students’ responses to the student worksheet.
