Development and evaluation of software for smart devices to support educational experiments on acceleration

This paper reports the development and evaluation of software for smart devices to support educational experiments on acceleration in junior and senior high schools. Paper tape and time recorders are conventionally used for performing such experiments in schools. However, a long time is required to read out the measurements when using these devices. Long experiment times may hamper students' intuitive understanding of concepts. The proposed software for smart devices reduces the experiment time by using values obtained from acceleration sensors in a smartphone. We propose an experimental method with the proposed software and a wireless display adapter to support students' learning.
