Design And Practice Of Visual Programming Learning Activities Based On Computational Thinking Framework

The cultivation of computational thinking is becoming more and more hot,people are more and more aware of the importance of computational thinking,and find that computational thinking has gradually become a basic skill that everyone should have in today's society.The rapid development of the Information Society,a variety of problems emerge one after another,the use of computational thinking,the use of scientific methods to solve a variety of situations,a variety of subjects under the problem,can better meet the test of society.How to enhance their computational thinking,and through what tools to understand the level of computational thinking,is a problem worthy of study.Based on the three-dimensional framework model of computational thinking of MIT,this paper designs the teaching activity of visual programming course.And in the real classroom teaching practice,students get feedback on the curriculum,and analysis of this practice research on the level of students' computational thinking whether there is a role and impact.In the stage of literature collation on the theoretical basis of the related concepts of this study,this study combs the current situation of relevant research at home and abroad,and makes a comprehensive understanding of the computational thinking,the evaluation of computational thinking,the training mode of computational thinking,and the teaching of visual programming,learn from the experience in this article.In the process of designing teaching activities,combining with specific teaching contents and specific teaching tools,the ADDIE teaching design model is used to train the thinking ability,the teaching activity of visual programming course based on three-dimensional frame of computational thinking is designed.And in YJ primary school in a third-grade class teaching practice research.The teaching goal is to develop students' computational thinking,and focus on the five categories in the definition to meet the requirements of the three-dimensional framework.Then through the implementation of teaching activities,to provide students with a variety of learning situations,activities,at the same time,let students draw flow chart to sort out programming ideas,and gradually develop students' computational thinking ability.In the assessment stage,this study uses the computational thinking test in the UKsection of the global computational thinking challenge as a computational thinking assessment tool.Each test is a task,and students not only have to choose options,you also need to explain the choice reasonably and clearly,that is,how the task was accomplished.Before the beginning of the study,the subjects' computational thinking level was tested in the early stage.After each round of teaching practice,they were tested once,four times in a whole time period,finally,the results of the calculation analysis,can be based on the computational thinking framework of visual programming teaching activities,can significantly improve the level of thinking students.
