Development of a STEAM4 INNOVATOR-Based Learning Process Using a Leaf Compression Machine to Enhance Students’ Innovation and Environmental Problem-Solving Skills

Abstract

This study aimed to develop a STEAM4INNOVATOR-based learning process using a leaf-compression device and to examine its effects on upper secondary students’ innovation skills and environmental problem-solving skills. The research employed a One Group Pre-test/Pos-test Design with 30 student environmental leaders. The research instruments, including a learning management plan and two skill assessment tools, demonstrated acceptable content validity (IOC = 0.75–0.88). The learning process followed the four stages of STEAM4INNOVATOR—Inspire, Ideate, Invent, and Implement. The results revealed that post-instruction scores for both innovation skills and environmental problem-solving skills were significantly higher than pre-instruction scores at the .05 level (t = 47.61 and 75.99, respectively). The normalized gain values were 0.67 and 0.68, indicating medium-to-high improvement. Qualitative data from observations and reflection interviews further showed that students demonstrated enhanced creativity, collaboration, problem-solving abilities, and environmental awareness. Overall, the STEAM4INNOVATOR learning process integrated with a leaf-compression device effectively fostered students’ innovation and environmental problem-solving skills, enabling them to design practical solutions to real environmental issues within their school context.
