Abstract
Learning through experimentation is a teaching method that allows students to conduct investigations through planning, implementation and discussion. However, the implementation of experiments is less emphasized due to limited teaching time and insufficient laboratory equipment, thus reducing students’ interest in Physics subject. Therefore, this study aims to develop an Arduino-based portable kit for force measurement and to test the reliability of the developed measurement kit. The development of this measurement kit was determined for Pascal’s law to diversify the practice in this topic. This kit consists of pressure sensor, Arduino microcontroller, android device and Bluetooth module. This study used a questionnaire instrument to measure the reliability of this kit. The validity of the kit was obtained from two (2) experts, and its reliability was evaluated from 15 Form 4 students through questionnaires. The result of the study showed a satisfactory reliability level with Cronbach alpha of 0.88. Therefore, it is expected that the development of this measurement kit can facilitate teachers in the teaching process and enhance students’ interest in Physics subject in Malaysia.
