ABSTRACT

Communication skills are very important for students in the 21st century era. The use of appropriate teaching materials can develop the necessary skills. Researchers think it is necessary to develop teaching materials in the form of Student Activity Sheets in an effort to improve communication skills. This research was conducted to determine the development process, feasibility and effectiveness of STEM-based science learning worksheets in improving students' communication skills. The design of this study uses research and development with the ASSURE model. Research instruments in the form of interviews, observations, and questionnaires. 5th grade students of MI Al Ittihad Ciampea Bogor were used as subjects in this study. The results of the study stated that the development product was feasible to use according to the results of the percentage assessment of material experts by 90.7%, linguists 94.4% and design experts 84.1% which were categorized as very valid. Students' communication skills can be seen from the increase in the pretest and posttest of the experimental class by 14.6 and the control class by 7.6. It can be concluded that the development of STEM-based worksheets is feasible and effective to use to improve communication skills.
