Research On The Application Of Reverse Thinking Model In The Teaching Of Graphical Programming In Junior High School

Nowadays,the speed of scientific and technological progress is accelerating,and the progress in the field of information technology is particularly obvious.The new era has put forward new requirements for the quality of talents,and people attach importance to information literacy and innovative thinking.The important purpose of programming education is to equip students with information literacy and innovative thinking.Graphic programming is intuitive,easy to operate and rich in resources,so it is included in the information technology class of compulsory education.Although the value of programming education continues to highlight,the programming problem solving path preset by teachers in class is not conducive to the development of students’ innovative ability.The Backwards Thinking points to the development of higher-order thinking ability,and can exercise students’ innovative thinking instead of presupposing an answer.However,at the same time,it also puts forward new requirements for teachers.In order to further improve the teaching of graphic programming,the application of reverse thinking learning model in graphic programming of junior high school is explored.This study carried out the following five aspects of work:(1)Sort out the development status of design-based learning,Backwards Thinking and graphical programming,and clarify the relationship between different concepts.(2)Carry out preliminary analysis of Backwards Thinking and graphic programming teaching in junior high school,including teaching environment analysis,learner characteristics analysis and teaching content analysis,and find out the advantages of applying Backwards Thinking.(3)Based on the Backwards Thinking,graphic programming teaching activities of junior high school are designed in combination with classroom teaching and various links and related elements of the Backwards Thinking.In addition,according to the process of curriculum teaching activities and the Backwards Thinking,this study puts forward corresponding strategies for before,during and after class.(4)According to the existing curriculum and students’ ability requirements,this study selected students in Grade 8 of L Middle School in Guangzhou to carry out three rounds of action research.The Backwards Thinking was applied to the teaching of graphic programming in junior high school.Experimental data were collected in the practice process,and the existing strategies and teaching design were revised and optimized after each round of action research.(5)After the three rounds of action research,analyze the collected data,summarize the modified application strategy,and review and summarize the whole process of the research.The results show that the Backwards Thinking applied in the graphic programming teaching of junior high school has played a positive role.It can be divided into the following aspects:(1)Based on the Backwards Thinking and combined with the characteristics of graphic programming in junior high school,the corresponding teaching activities are designed.(2)Put forward the application strategy of Backwards Thinking in graphic programming of junior high school,and after three rounds of action research,finally formed a relatively perfect application strategy.(3)Through comparison,it is found that students’ creativity tendency level has been significantly improved.(4)Through the analysis of students’ course satisfaction questionnaire,it is found that it is feasible to apply the teaching process of Backwards Thinking to the graphic programming teaching of junior high school,which has significant effects on improving students’ classroom participation and learning effect.(5)By comparing the changes of students’ performance in three rounds of graphic programming teaching practice,it is found that students’ performance has been improved,which reflects the deepening of students’ knowledge and skills of graphic programming.
