摘要

本研究的目的是制作一款高中物理碰撞材料教具形式的产品。所开发的辅助装置由Arduino作为中央控制器,光电二极管传感器和红外传感器作为球体运动探测器,安装在高达100厘米的管轨侧面。辅助装置可以自动记录弹跳球的时间和高度。研究方法采用ADDIE模型进行R&D开发研究,包括分析、设计、开发、实施和评价五个阶段。所使用的变量是球的类型和基座类型的变化。使用的球有三种:乒乓球、高尔夫球和网球。底座类型有陶瓷地板、不锈钢地板和亚克力地板。球反弹是弹性碰撞,部分原因是它的恢复系数值为0 < e < 1。这个实验是通过忽略空气阻力和跟踪摩擦来完成的。学生可以借助工作表进行观察,这些工作表也被开发成一个单元包。通过验证测试阶段,该产品的工作表获得了91%的价值,教具获得了81%的价值,这意味着工作表和教具适合作为支持学习物理的教材。

The Development of Educational Aids for Restitution Coefficient Experiment Using Microcontroller
This study aims to produce a product in the form of high school physics teaching aids for collision materials. The aids developed consist of Arduino as the central controller, photodiode sensor, and infrared sensor as ball motion detector mounted on the side of the tube track as high as 100 cm. The aids can record the time and altitude automatically on the bouncing ball. The research method used is R&D development research with the ADDIE model, which includes five stages, analysis, design, development, implementation, and evaluation. The variables used are variations in the type of ball and the pedestal type. Three types of balls are used: ping pong, golf, and tennis. The base types are ceramic floor, stainless steel, and acrylic. The ball bounce is an elastic collision partly because it has a restitution coefficient value of 0 < e < 1. This experiment is done by ignoring air resistance and tracking friction. Students can make observations with the help of worksheets, which were also developed into the one-unit package. Through the validation test phase, the product has the worksheets get a value of 91% and the teaching aids 81%, which means that the worksheets and teaching aids are suitable for teaching materials to support learning physics.
