Design And Practice Of Secondary Vocational Computer Teaching Cases Based On Reverse Computing Thinkin

In today’s world,the development of information technology should have the greatest impact on mankind.Nowadays,the advantages of information technology are reflected in all aspects of our lives,constantly changing people’s thinking and daily communication.As an important part of the core literacy of information technology,computing thinking has a more and more important impact on students’ learning and life style.Based on the in-depth understanding and research of secondary vocational colleges,case design is carried out for typical computer courses in secondary vocational colleges,teaching practice is carried out,and course case design based on reverse computing thinking is explored to escort the professional course learning of secondary vocational students.The research is mainly carried out in the following four stages:The first stage: determine the research content.Through literature research,interview and investigation,this paper analyzes the situation of domestic and international education reform,focuses on the problems existing in computer teaching in vocational education,and combines a variety of pedagogical theories based on the typical types of problems in the program design course for the computer major in secondary vocational education,This paper puts forward the design of computer teaching case in secondary vocational school based on reverse computing thinking.After in-depth communication with teachers and students in practice,three typical topics were selected from the course of program design.The second stage: teaching design.According to the requirements of curriculum standards and the characteristics of secondary vocational students,determine the appropriate teaching scheme and plan.In the process of instructional design,reverse thinking and computational thinking will be combined,based on the examples loved in life,to explore and analyze,and summarize the general principles.After repeated deliberation and continuous improvement,it presents a relatively complete teaching design content for the smooth development of later teaching practice.The third stage: carry out teaching practice.First,determine the teaching time according to the basic situation of the practice place and form the course schedule.Then,carry out teaching practice according to the curriculum plan.Finally,it analyzes the results of the development of teaching practice from different angles,summarizes the practice process,reflects on the shortcomings in the practice process,and summarizes the areas that need to be improved,so as to realize the mutual benefit of teaching and learning.The fourth stage: teaching summary and prospect.Summarize and prospect the designed teaching cases and the teaching practice carried out,summarize the main work completed and the research results obtained,and make a summary on whether it has achieved the expected teaching effect,whether it is suitable for the development of classroom teaching,and whether it is good at the connection of course content,so as to make a good prospect for the future development of computer course in secondary vocational school,Achieve the effect of promoting reform through education and introspection.Based on the reverse calculation thinking,three typical course contents of computer in secondary vocational school are designed,and a new teaching mode is used to carry out teaching.Starting from the reality of life,students’ learning interest is improved,teachers’ teaching burden is reduced,new design ideas are provided for front-line teachers to carry out teaching,and meet the training requirements of modern teaching courses.
