Research On The Teaching Mode Construction Of Information Technology Course In High School For The Cultivation Of Computational Thinking

The rapid development of information technology has promoted the comprehensive reform of the goal,mode,form and content of education.The new curriculum standard of Information technology for senior high schools issued in 2017 clearly states that cultivating students' core literacy should be regarded as the teaching task and fundamental purpose.As one of the four core qualities of information technology,computational thinking not only plays a complementary role in other core qualities,but also has a close relationship with the cultivation of students' innovative ability and the improvement of their problem-solving ability.Based on the research status of computational thinking and activity theory,this study explores the teaching mode of information technology curriculum with the core goal of cultivating high school students' computational thinking.The following researches are carried out :(1)the concept and characteristics of computational thinking are elaborated,and the theories involved in this study are introduced.(2)analysis of the high school information technology new curriculum standard and 2017 high school students thinking ability of the current performance,summarizes the develop computational thinking information technology course teaching principle,on the basis of the constructed in terms of cultivating high school students thinking as the core target of information technology course teaching mode,with teachers and students based on the theory of the activity "double line" as the main body of new teaching mode.This paper expounds the new teaching mode constructed by this research in detail from four parts: setting up the scene,integrating the information,constructing the model,solving the problem,solving the problem,optimizing the scheme,evaluating the reflection and transferring the application.(3)The algorithm content in senior high school information technology courses is selected as the teaching practice content,and the teaching case is designed under the guidance of the information technology course teaching mode constructed in this research,so that this teaching mode can be applied in senior high school information technology teaching practice,and the teaching implementation effect of this teaching mode is evaluated.Through teaching experiments,the following conclusions can be drawn: The information technology course teaching model constructed in this research improves students' ability to solve practical problems in specific classroom teaching activities.Students have a profound understanding of this teaching model and can experience the change in thinking brought by this teaching model.In the process of teaching practice,students' thinking ability has also been improved.
