Development of learning activities for angular speed and angular frequency measurements using hall sensor and GoGo board learning toolkits

Abstract

This research has three objectives: (1) to develop a module for physical measurement and data recording using the GoGo Board learning kit; (2) to develop a manual and a set of physics experiment activities that utilize Hall effect sensors and the GoGo Board for measuring physical quantities; and (3) to evaluate the use of the GoGo Board and Hall effect sensors in physical measurement and data recording by a group of 16 pre-service teachers and 18 undergraduate students, majoring in physics at Chiang Mai University. The researcher conducted experiments and developed the physical measurement and data recording module using Hall sensors with the GoGo Board, including pre-learning and post-learning tests on understanding the Hall effect and the application of Hall sensors, comprising 12 multiple-choice questions, activities sheets on the Hall effect and Hall sensors, and activities for determining the angular velocity of a wheel and the spring constant, which were tools used in data collection with the research participants, along with semi-structured interviews. From the analysis of both quantitative and qualitative data, it was found that after learning with this module, students significantly improved their knowledge and skills from before learning, with a statistical significance of z = 5.0944, p = 0.0000003, using the non-parametric Wilcoxon signed ranks test, and an effect size of 0.87, indicating a significant difference in post-learning scores from pre-learning scores. Additionally, the overall learning gain of the students was 0.73, indicating a high level of learning improvement. Statistical analysis using all three methods indicated the effectiveness of the learning module. Furthermore, the research participants were highly satisfied with the set of physics experiment activities using Hall sensors and the GoGo Board, with a satisfaction level greater than 4. The overall activities were deemed appropriate, helping students understand the principles of physics and the operation of Hall sensors, enhancing their skills in using the GoGo Board and conducting physics experiments significantly, making it easier for students to understand and apply compared to using Arduino, which is more complex. These activities not only enhanced understanding of coding and code logic but also enabled students to practice thinking and problem-solving skills effectively through hands-on experiments.
