A Study on Teaching and Learning Model of Undergraduate Coding Education Using Arduino

Abstract

Technologies leading to the fourth industrial revolution, such as ubiquitous mobile internet, powerful sensors, and artificial intelligence, are rapidly changing our daily lives and industrial structure through the Internet of Things (IoT). As a result, computer programming is now regarded as an essential skill for 21st century students, and coding education aimed at promoting computational thinking is becoming a core component of curriculums not only in elementary and middle schools, but also in universities. In particular, the rapid development of the IoT, which is one of the main technologies enabling the connection between real objects and the digital sphere, has resulted in a need for more undergraduate coding education in many universities. This study proposed a teaching and learning model for IoT concepts that utilizes Arduino for the coding education of undergraduate students, and analyzed its effectiveness. In order to understand the concept of the IoT, students organized project scenarios related to real-world subjects, and added creative designs. Each team then implemented IoT project works using five sensors and actuators. A questionnaire was used to evaluate the effectiveness of the model, the results of which confirmed that the teaching approach helped to improve the students' understandings of the IoT and better understand the technologies underlying the fourth industrial revolution technology in general, as well as gain the coding abilities to implement new ideas in the digital sphere.
