Computer Science Unplugged for Developing Computational Thinking and Mathematical Thinking

The purpose of this study is to make learning material that can develop both Computational thinking and Mathematical thinking. This study suggest a hamburger flowchart as a teaching material that combines the three elements of "unplugged", "thinking from the end " and "mathematics class". Using this flowchart, basic experiment was conducted for 8 to 12 years old. The purpose of this experiment is to confirm whether it is possible for children to develop both Computational thinking and Mathematical thinking by using the hamburger flowchart. We evaluated both Computational thinking and Mathematical thinking from the state in this class and the content of the worksheet and prior and subsequent tests. As a result, the state related to Computational thinking and Mathematical thinking increased, and the correct answer rate of many children increased from the prior test to the subsequent test. Therefore it turned out that the hamburger flowchart affects mathematical thinking.
