Abstract [en]

In the present study, four practical exercises were introduced in a university-level mechanics course, in order to provide students with shared, personal, embodied experiences of physical phenomena in relation to the taught content. The practical exercises were performed during 10-15 minutes with subsequent discussion in random groups of 3-4 students during recitation sessions. Two of the exercises involved physically experiencing the reduced force of raising a 5 kg weight with a rope and a system of pulleys compared to with a rope alone, and finding the centre of mass of an object by holding under the object with ones hands and moving the hands toward one another. Video analysis of selected episodes of students’ interaction with the exercises reveals how they coordinated gestures and spoken language in expressing their conceptual understanding of the phenomena. In a subsequent group interview, participant physics teacher students expressed that the exercises were useful for feeling physically what they had previously only calculated. Apart from grounding conceptual understanding in physical experiences, the course evaluation shows that participation in random small groups led to increased communication among students that did not know each other before, thereby contributing to the development of a learning community.
