Multi-Stakeholder Feedback Analysis of a Solar-Powered IoT Hydroponic STEM Module: Impact, Perceptions and Optimization

Abstract

This study presents a comprehensive evaluation of a Solar-Powered IoT Hydroponic Module, implemented as a hands-on STEM educational workshop for secondary school students in collaboration with Universiti Malaysia Terengganu. Structured feedback was collected from student participants, accompanying teachers, and organizing committee members to assess the workshop’s real-world impact. The results indicate strong engagement and satisfaction: 90% of students rated their overall experience as excellent, with 80% reporting high confidence in using IoT platforms. Teachers observed significant gains in student engagement, technical skills, and awareness of Sustainable Development Goals, particularly SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action). Committee members reported high satisfaction with event planning and collaboration, underscoring the value of multidisciplinary teamwork. Qualitative feedback also highlighted the module’s strengths in fostering technical proficiency and environmental awareness, while also identifying areas for improvement such as increasing hands-on activities, optimizing session pacing, and enhancing technical support. These insights have informed actionable recommendations for future workshops. Supported by the 2024 IEEE Region 10 Educational Activities Development Grant, this feedback-driven analysis affirms the module’s effectiveness in advancing experiential STEM learning and sustainability education, and provides a robust framework for continuous program improvement.
