The Assessing Computational Thinking in Making Activities (ACTMA) project aims to create embedded, adaptive, and culturally responsive activities and formative assessments of computational thinking (CT) in STEM that can be used in informal learning spaces such as makerspaces, but can also be brought into more formal physics classroom experiences. Our 2017 2-week summer program brought 15 students together to run a second pilot of our activities and assessments created and iterated upon, thus far in the project. The summer program was facilitated by classroom physics teachers who implemented the activities in their classrooms during the school year. Our team has been focusing the research on what cultural responsiveness means for developing CT in making environments, and how to best embed assessments in making activities.
