Development of Student Worksheets Based on Think Pair Share to Improve Student Science Communication in Junior High School Sains Learning

The current level of science communication skills was still low, so a solution was needed, one of which was the development of a Student Worksheet based on Think Pair Share. The purpose of this research was to determine the validity, practicality, and effectiveness of Think Pair Share-based Student Worksheets. This research included development research with the ADDIE model. Data collection techniques were interviews, observation, questionnaires, tests, and documentation. Instruments used were: validation sheet, implementation observation sheet, test, and student response questionnaire. The results of this research showed that the Think Pair Share-based Student Worksheet was valid based on an average validation percentage of 91.92%. It was practically used based on an average implementation result of 90.90%. It was effective based on the results of the N-gain analysis of 0.74 and based on average student response results of 86.27%. It was concluded that the Student Worksheet based on Think Pair Share was valid, practical, and effective in improving science communication skills
