In this report, we designed and implemented a class based on the following three aims for the "Practices in Products Design" for the first-year students for the first semester of 2023. (1) To get the students interested in machines and to have them have high expectations for their future studies, (2) To understand the flow of manufacturing by experiencing planning, design, and prototyping, and (3) To understand the difficulty and importance of teamwork in manufacturing products. The results showed that 83.8 % of the students were motivated and 70.9 % of the students were relatively satisfied with the class. The students were able to find what they wanted to learn in the next semester and beyond, and they expected to work as manufacturing engineers by being involved with students from different backgrounds. Communication was one of the most important perspectives in manufacturing for 36.4% of the participants, and they became aware of the importance of communication through their interactions with other participants of different backgrounds. In addition, 63.6% of the participants said that they realised an improvement in their communication skills. As described above, we were able to guide the students in the expected direction in terms of (1), (2), and (3), which we considered important in the design of the class.
