Development of a Lesson to Learn Problem-Solving Methods Using the DX Concept in “Period for Inquiry-Based Cross-Disciplinary Study”

Abstract

　In response to the lack of research on classes that teach problem-solving methods using the DX concept, this study aimed to develop a class program for teaching problem-solving using the DX concept within the “Time for Integrated Inquiry” curriculum at upper secondary schools. The study involved conducting a class for first-year students at a public senior high school. The post-lesson questionnaire showed a generally positive subjective evaluation of the students' understanding of the class content. However, in the multiple-choice test assessing their comprehension of DX cases, only a few students provided correct answers. This indicates the need for further investigation into the thinking process and the communication method of these concepts.
