End of Session Reflection and Debriefing
Teacher briefly explains the computational thinking (CT) skill embedded in the Problem Solving Process Diagram. Using the problem solving process diagram, the teacher will ask students to identify what kind of problem solving skills/process/computational thinking they used in this session and explain how they used it. The following are some sample questions that can guide the debrief.
What did I learn today?
What problem solving skills/processes or CT components in this diagram did I use today?
How did I use the problem solving skills/processes/CT components?
