Graphic Design and Usability Evaluation of Physical Programming Teaching Aids

Physical programming is an innovative way of programming, which makes the code in the computer into physical programming module, so that preschoolers learn to program as simple as building blocks. However, due to the abstraction of the programming process, one of the difficulties in the teaching of physical programming is that it is difficult for preschoolers to understand teaching aids. Graphic teaching aids design is the main way to solve children's understanding difficulties. This also means that whether physical programming teaching aids are understood by children, whether they are attractive or not, and whether they can support real task scenes are the keys to guide children to learn programming smoothly. Based on the typical game scenes, this study compares four kinds of teaching aids graphics to find and improve the usability of physical programming teaching aids, which provides theoretical support for the development of children's programming teaching aids.
