Research On The Practice And Application Of Computational Thinking Cultivation Of Information Technology In Junior Middle Schools Based On Problem Scaffolding

The 2017 "General High School Information Technology Curriculum Standard" clearly pointed out that the teaching task of its subject is to improve students’ comprehensive ability,vigorously develop information literacy,scientific and cultural literacy and lifelong learning ability,enhance students’ autonomy and strengthen the concept of lifelong learning..Computational thinking,as one of the basic components of core literacy,is an important factor for students to adapt to the new era and lifelong development.In the new curriculum standard,computational thinking training has received considerable attention,but this is a longer stage and should be carried out and popularized in the K-12 stage.At present,computational thinking education is still a new and hot topic,and the main front for computational thinking education is information technology.How to improve the ability of problem solving has always been a concern of the educational circle.American 21 st Century Skills System focuses on the cultivation of students’ problem-solving thinking,especially solving problems in complex situations to improve learners’ knowledge and skills,which is the most needed quality for talent cultivation in the 21 st century.To solve the problems in the information age,the need to support by effective learning support,information technology is a kind of classroom problem solving oriented class,problems need more effective support to support,but the problem of stent type selection of stents and how the problem of application in actual teaching needs to be further discussed.Based on this background,this study is mainly carried out from the following aspects: First combed the domestic and foreign about the computational thinking,learning,stents,problem,information technology and junior high school classroom and related literature,to clarify the concept,development course and present situation,to further study the bracket construction,calculating the design process of thinking training mode,how to develop middle class activities such as information technology related research content;Second,this study constructivist learning,activity and the theory of the zone of proximal development as the research foundation,this paper expounds the problems based on the characteristics of scaffolding instruction,elements and construction should follow the principle of,combined with the feature of middle school learners,thus build the design based on the problems of junior high school information technology teaching activity design model to calculate the thinking training.Finally,this study conducted in urumqi first W middle school for nearly three months of teaching practice,through the collection,processing and analysis of experimental data,to verify the junior middle school information technology calculation based on the problem of stent thinking training activities in the implementation of the computational thinking ability of students,learning interest,and satisfaction of effects.Through the analysis of the learning effect,it is concluded that :（1）the teaching activity model of junior middle school information technology computational thinking training based on question frame constructed in this study is effective;（2）It can improve students’ computational thinking ability to a certain extent;（3）It plays a positive role in improving students’ interest and enthusiasm in class.
