Abstract: Computational thinking has become popular in education research.More students can learn computational thinking in visual programming.Previous studies center on the motivation level that visual programming produces,but don’t focus on what kinds of computational thinking students learn from visual programming.This paper made semantic analysis on games and simulations that students created by using visual language on the basis of program behavior similarity,brought up an automatic and visual assessment method that is computational thinking pattern graph.This method can evaluate computational thinking pattern used in games and scientific simulations created by students,at the same time,points out students’ possible transfer of computational thinking from game design to scientific simulations.

Key words: Computational thinking,Visual programming,Computational thinking pattern,Recognition of computational thinking
