Fostering Computational Thinking and Systems Thinking through Aquaponics Capstone Projects

Abstract

In today's world of growing complexity and interconnectedness, computational thinking (CT) and systems thinking (ST) are imperative for everyone to solve complex problems, create advanced solutions, and innovate cutting-edge technologies and systems. Traditional teaching approaches for CT and ST offer limited avenues for applying the knowledge and skills learned in class. This paper presents and discusses the design and development of intelligent aquaponics capstone projects to foster CT and ST in undergraduate students. Specifically, students designed and built an automated aquaponics system with internet of things for real-time remote monitoring and control. Aquaculture and hydroponics subsystems, hardware and software components, communication networks, and data acquisition and analysis of fish and plant growth were integrated and tested, with high yield and quality of fish and vegetables. Attributable to the multidisciplinary and multifaceted high-tech aquaponics system, students can broaden and deepen their theoretical understanding and practical experience of CT and ST.
