The remote teaching established on an emergency basis due to the Covid-19 pandemic brought great challenges to educators, who needed to adapt teaching routines quickly to conduct classes. In design education, material experimentation carried out in design laboratory environments is essential for training students to design products that, through physical constructions, creatively explore their ideas or put them to tests for the validation of design concepts and solutions, in a teaching environment shared by students, teachers and technical professionals. This dissertation presents the report of the author s experience in the elaboration and implementation of work alternatives that allowed the continuity of the practices of material experimentation, through physical representations, in disciplines supported by the Laboratory of Models and Prototypes, belonging to the graduation course in design of products, from PUC-Rio, during social isolation. The theoretical framework that supports the dissertation includes authors such as Donald Shön, Nigel Cross and Antônio Santoni Rugiu and through participatory methodology, using bibliographical and documentary research, we seek to observe and reflect on the place of experimentation in design laboratories and on teaching -learning that took place in these spaces, highlighting the importance of physical representations in the development of product design. Finally, the proposals that were implemented in an emergency remote teaching context are presented, as a way to enable the students work routine, in their homes.
