the study aims to determine the impact of the EarlySTEM Leader Teacher Professional Development (PD) Program for early childhood and primary school teachers on creating APoKS. We used case study research to get a greater understanding of the lesson planning skills developed by the teachers within the Early STEM Leader Teacher PD Program. The data gathered from teachers’ lesson plans analyzed using STEM lesson plan evaluation rubrics. The rubric evaluates seven features of BTHP including types of the social product, main disciplines in lesson plans, and integrated disciplines, objectives that reflect the 4Cs.
