Abstract

This project is an engineering education activity that involves building various structures using 4D Frame and evaluating their seismic performance. A DC motor is used to generate vibrations, and accelerometers are installed on each structure to measure movements in the x, y, and z directions. Through coding and circuit assembly using Arduino, students can learn concepts of acceleration and seismic design through hands-on practice. By evaluating and analyzing the performance of their own structures, students develop engineering thinking skills and gain practical experience in this creative educational project.

Abstract

The 21st Century brings many new challenges and opportunities, mainly driven by technological advancements, globalization, and a rapidly changing workforce landscape. The main goal of education is no longer academic success but also equipping students with skills called 21st century skills. The 21st century skills needed to solve complex 21st century problems such as net zero challenges. Net Zero aims to achieve carbon neutrality by balancing greenhouse gas emissions and removal from the atmosphere. The research aims to develop, implement, and analyze the effects of PjBL-STEM learning on students' 21st century skills to address the net zero challenge. The research also examined how students respond to renewable Energy learning using the PjBL-STEM model through a solar-powered tractor project supported by the 4D Frame. This study used a conversion mixed methods approach to transform qualitative data into quantitative data using established rubrics. The results showed that PjBL-STEM learning associated with environmental issues enhances students' 21st century skills and significantly affects the teaching of students' critical thinking. Meanwhile, students showed good performance in communication, collaboration, and creativity skills through discussion activities, teamwork, presentations, and EDP.

Abstract

The core objective of this capstone project is to rigorously analyze the challenges encompassing green energy utilization and propose viable solutions to overcome them. A small-scale model of a modern city was constructed to demonstrate various energy sources, including renewable (wind and solar) and non-renewable (fossil fuels represented by a 9V battery, and nuclear energy represented by a 12V battery). Our findings underscored that renewable energy sources demand significant advancements to enhance power delivery efficiency, whereas fossil fuels, although easier to deploy, pose severe environmental threats. Nuclear energy emerges as a potentially robust alternative, balancing both power delivery and environmental impact, albeit with challenges in waste management and recycling. This project also harbored an educational aim to incite interest and knowledge among young learners towards STEAM fields, thereby fostering a better understanding of green energy and its pivotal role in modern power distribution systems. Through a comprehensive analysis and hands-on demonstration, we aim to contribute to the ongoing discourse on advancing green energy solutions to meet the burgeoning demand for sustainable and efficient power generation and distribution.

Abstract

Natural disasters such as earthquakes, tornadoes, and hurricanes result in immense destruction of its surrounding environment, filling it with rubble. Within these rubbles, it is easy for people to be trapped, leading to suffocation or life-threatening injuries. HERO aims to aid rescue efforts by speeding the process of finding humans. By integrating artificial intelligence and 4Dframe, HERO has developed a car that is optimal for human search missions. By implementing an audio sensor and a light 4Dframe chassis, the car can go through crevasses and signal to rescuers whether a person needs help. This product focuses on optimal design as it is trained to navigate rough terrain and find humans under rubble. Furthermore, this design will foster children's curiosity about AI's versatility and inspire them to create projects focused on simplicity and creativity using 4Dframe, leading to honed interest in STEAM.

Abstract

The project "A Clean World through Phygital" addresses environmental issues that arise in daily life, particularly the challenges of waste separation and recycling, by utilizing the 4D Frame Mechatronics Kit and AI technology. This system uses AI to automatically recognize and sort waste, providing a practical solution that promotes recycling and contributes to environmental protection. Alpha Team, consisting of students from KCIS and Samyook High School, leverages this project to test their technical skills, creative problem-solving abilities, and to realize educational value while gaining future-oriented learning experiences. Through the integration of new technologies with existing educational tools, the team explores the potential for innovative educational content and examines the use of 4D Frame as a versatile learning tool.
