DEVELOPING INDICATORS FOR SCIENCE TEACHER COMPETENCY IN STEM-ESD LEARNING

Abstract

Science, Technology, Engineering, and Mathematics (STEM) education focused on Education for Sustainability Development (ESD) can help students improve STEM skills and science procedures. STEM-ESD teachers are needed to acquire these competencies. This study aims to develop and determine the validity and reliability of STEM-ESD competency indicators for science teachers with Technological Pedagogical Content Knowledge (TPACK) standards. Descriptive research includes competency indicator development, indicator testing, and validation. This study employed Rasch modelling to assess 51 questionnaire items. This study included 108 science teachers. The results showed that STEM-ESD competencies were developed into 3 domains: planning, implementing, and professional development. The planning domain includes Content Knowledge (CK), Pedagogical Knowledge (PK), Technological Knowledge (TK), Pedagogical Content Knowledge (PCK), Technological Content Knowledge (TCK), Technological Pedagogical Knowledge (TPK), and TPACK. Meanwhile, the implementation and professional development domain includes TPACK indicators. The results of testing with the Rasch model show that the competencies developed can measure what should be measured (with no other dimensions outside the construct) because the raw variance explained by measures is 69.7%, which is classified as a very good criterion. Then, the unexplained variance in the 1st-5th period shows results that are smaller than 15%. A total of 42 indicators were declared valid. Furthermore, the reliability results are shown by the Cronbach alpha result of 0.99 with a very good category. The development and validation of this indicator is expected to be a reference for teachers to know what competencies they must have in teaching STEM-ESD in science learning.
