With the increasing advocacy for CT integration in K-12 education, it is important to consider how teacher education programs could better prepare teacher candidates (TCs). At the Faculty of Education at Western University, CT has been included in the curriculum as part of the teacher education program through the course Computational Thinking in Mathematics and Science Education, oriented to Intermediate/Senior (Grades 7 to 12) preservice teachers. In this paper, we describe the case study of the latest cohort of the CT course (Fall 2017). We aimed to answer the question: What key understandings about CT did teacher candidates develop through their participation in the course?
