The Scaffolding Strategy Is Used In The Quasi-experimental Study Of Students' Computational Thinking In The Scratch Classroom

With the advent of the information age,computational thinking has been highly valued by the education community.Many countries have also included the cultivation of computational thinking in the important content of information technology courses.China has also included computational thinking in the new version of the general high school information technology discipline four.One of the core literacy.According to the domestic and foreign literature research,the cultivation of computational thinking is mainly reflected in the information technology classroom.At the same time,the learning scaffold has begun to assist teachers in the teaching of information technology widely to better cultivate students' core literacy capabilities.To this end,based on the current research situation at home and abroad,this article uses Scratch classroom teaching as a carrier to design a teaching design that incorporates a variety of learning scaffolds,with a view to promoting the better improvement of learners' thinking ability in computing.In this study,through combing the relevant literature,systematically study computational thinking and learn the scaffold.Clarify the relevant steps of computational thinking:decomposition,pattern recognition,abstraction,algorithm.Based on the theory of the nearest development zone and constructivist theory,it combines a variety of learning scaffolds with the computational thinking training process,and designs teaching cases based on specific teaching content.Finally,through the teaching practice in the fifth grade students of a primary school in Shanghai City,the evaluation of the improvement of students' thinking level in computing is evaluated.The results of this research show that the teaching model that integrates multiple learning scaffolds can significantly improve the students' computational thinking ability compared with the traditional teaching model.The students apply the four steps of computational thinking in the process of completing tasks More and more proficient,and then prove that the application of the learning bracket has a better effect on the cultivation of students' computational thinking,and can play a better guiding role for students.
