Developing Simple Tools for Measuring and Evaluating Students' Works with a Smartphone

In this study, we developed a simple set of tools for a teacher to efficiently and easily evaluate and measure the accuracy of the result of students’ craft works. This tool is developed for running on a smartphone, and has three functions; 1. Measuring the flatness of surfaces, 2. Measuring the accuracy of connected parts, and 3. Taking photos of the working process and final result. The result of the evaluation is sent to LMS (Learning Management System) and stored. It works as a part of an integrated management system. Despite only having three functions, this tool can solve chronic problems and drastically reduce the workload for general Japanese teachers. Without this tool, one teacher is solely accountable for checking and evaluating a vast number of students’ works in a very short period of time.

Development of a Workpiece Evaluation Support Mechanism for Students

In the technology education of Japanese junior high schools there is a manufacturing activity where the students make something, like a bookshelf. The activity encompasses a variety of skills, for example, sawing and planing. It is difficult for the students to evaluate skills objectively by themselves in the manufacturing activities. This paper proposes a mechanism to support students with objectively evaluating skills of their own. The mechanism creates objective evaluations about the angle and the surface roughness of a workpiece by using the sensors of a mobile device. We proposed a mechanism Workpiece Evaluation Support Mechanism for Students, and confirmed that the mechanism is simple in terms of the displayed information and the number of steps.
