It is important that students practice experimental skills, and for this visualization of experimental skills and evaluation of achievement are necessary. The metrics of the experiment and curriculum of each college are specified to facilitate evaluation of the achievement of experimental skills, thus promoting effective technological education. It is possible to clarify the metrics and visualize student skills. Indicating the achievement and effect of student technical education will then make it possible to improve student skills. Here, we propose to use the experimental evaluation sheets and experimental skill sheet to clarify the metrics of the experiment and indicate the achievement level. The introduction of evaluation of experimental skills has educational effects. First, the features of the educational content have been presented. The metrics and objectives in the experiment of each technical college will be systematically collected. As a result, the content and operation of education will be clarified. We will then visualize the experimental skills of students. Toward this end, we formulated five-level evaluation criteria for the elements of experimental basis, theory, measurement, analysis and report. We evaluate the experimental skills using these criteria. As a result, the outcome is visualization, we can expect through which we expect the skills of the students to improve be able to guide more students. Finally, for improving education, the skills sheet will be linked to the review of the curriculum and educational improvement.
