The study aims to propose puzzle game content for algorithmic thinking enhancement. The Korean 2015 Revised Curriculum presents learning understanding of algorithms through SW education. Puzzle take the form of games, which are suitable for attracting students' interest and participation, and are effective in understanding the underlying algorithms.
In this work we develop and apply content based on Parsons puzzle. The puzzle game operates by Drag & Drop method, which is also easy to use on tablets. The content is composed of text programming contents, but the class was organized to look at the structure of the algorithm with the teacher to prevent excessive grammar-oriented education, and the puzzle game allowed students to check the meaning of the code on the screen.
As a result of applying the developed program to elementary school students with sufficient SW education experience, it was shown that puzzle games could be effectively used to understand text programming algorithms, showing high interest in classes and understanding algorithms. On the other hand, the contents of text programming have been found to be difficult, and it is necessary to expand it to middle school students in the future to conduct follow-up research.
