Tóm tắt

STEM education, as outlined in the 2018 General Education Curriculum, requires enhanced learning activities through experiential learning and practical problem-solving, demanding that teachers proactively develop learning materials suitable for their teaching conditions. Among the biomaterials available, leaf veins have the potential to support STEM experiential activities, but there is currently no standardized process for creating these materials that meets pedagogical requirements. This research study was conducted using a design-based research method to develop and standardize a process for creating leaf vein materials for STEM experiential activities for middle school students. The research results have established a process for creating leaf vein materials that meets pedagogical requirements, receiving high praise from experts and demonstrating initial feasibility in practical teaching conditions in general schools. This paper contributes to standardizing the process of creating leaf vein materials pedagogically, supplementing the scientific basis for developing STEM learning materials from readily available biological materials and supporting teachers in organizing STEM experiential activities.
