Mazda supports the purpose of STEAM classes*1 offered by the Future Creation Department*2 of the Hiroshima Global Academy, a prefectural comprehensive junior and senior high school in Hiroshima, and provided classes*3 for second-year junior high school students at the school. Reflecting on the history of industry and the present, students engaged in discussion with their instructors as they considered the kind of society they would like to create in the future in 2030, when they will be playing active roles as adults. The 17 instructors from Mazda included several staff from the R&D department as well as production engineering and plant planning staff and engineers. In the practical phase of the classes, the students took on the challenge of making a muffler and adopted as their theme, "Let's learn about mufflers through a simulated experience of designing sounds and manufacturing." The instructors began by explaining the role of the muffler and how Mazda uses the principles of sound to produce the ideal sound they are aiming for. In the same way, the students then applied the principles of sound to design and create the sounds they wanted to produce. To do this, they made models using a variety of materials available in their immediate surroundings such as cardboard boxes, straws, plastic bottles and tissue. After completing their models, they sent them to Mazda for testing. At Mazda, we used measuring equipment that is actually used in development to verify whether the anticipated results could be obtained. Only this phase of the classes had to be conducted online, due to COVID-19 restrictions, and although it was difficult for both sides, when the desired measurements were achieved, the students let out cheers of delight. Some students, who seemed to have learned a lot through these classes, expressed their desire to become engineers in the future. The classes were also a learning experience for the instructors, one of whom commented, "It made me reconsider my work and reaffirm my motivation for working at Mazda. It was a valuable experience that will be a starting point for human resource development." For both students and instructors alike, the classes were a memorable experience.
