Recent years have witnessed an increasing emphasis on integrating computational thinking into school curriculums. This study deals with suggesting a course model including data collection tools for evaluating teachers' pedagogical content knowledge in teaching computational thinking via teaching robot programming. Taking the advantages of virtual educational robotics, the study addressed some steps to be used during the teacher training sessions. The results provide implications for educators who desire to provide training programs for teachers to prepare them to teach robotics. Using the suggested model, the instructional activities and the assessment tools will be structured for practitioners' use.
