Development of Chemistry Practicum Guidelines with the Support of STEM (Science, Technology, Engineering, and Mathematics) Integrating Character Education

Abstract

The implementation of the STEM-based learning approach is able to shape student character. One of them is using a chemistry lab guide based on the STEM approach. The purpose of this study was to determine the feasibility level of a chemistry lab guide based on the integrated STEM approach to character education based on the criteria of the National Education Standards Agency (BSNP) and the character level of students after using a validated practicum guide. This type of research uses the Research and Development (R & D) method with the ADDIE model development stages (Analysis, Design, Development, Implementation, and Evaluation). The data collection instrument consisted of a practicum guide validation sheet based on BSNP criteria and student character observation sheets. The data source in this study was 40 students of class XII SMA N 1 Tanjungbalai academic year 2020/2021 using purposive sampling technique of collecting samples. The results showed that the validation test for chemistry lab guides by expert validators stated that the chemistry practicum guidance based on the integrated STEM approach to character education was valid with an average value of 3.53 from a maximum scale of 4 which means it is feasible and does not need to be revised. Furthermore, the results of observations of the character level of students using a practical guide based on the STEM integrated approach to character education are very good with an average of 85.8%. Based on the results of character validation and observation, it shows that chemistry practicum speakers based on the STEM integrated approach to character education are feasible to be implemented in schools.
