This lecture discusses the 3T PLAY Project, which aims to teach transversal skills to engineering students through tangible activities. The focus is on a specific experiential activity designed to help students give and receive constructive feedback. The instructor explains the challenges students face when transitioning from analytical thinking to emotional self-management during feedback sessions. Through iterations of the activity, the importance of emotional awareness in teamwork is highlighted. Students engage in a hands-on task where they build a marble track under time pressure, which evokes various emotions related to teamwork dynamics. This activity not only teaches the mechanics of providing feedback but also emphasizes the emotional experiences that accompany collaborative efforts. The lecture underscores the necessity of feedback skills in engineering, where effective communication and management of technical teams are crucial for professional success. The insights shared aim to enhance students' self-awareness and improve their ability to navigate feedback situations in their future careers.
