Research On Secondary Vocational Information Technology Textbook Analysis And Teaching Practice Based On Objective Matrix Method

In recent two years,our country has paid more and more attention to secondary vocational education.In 2021,the Implementation Plan of the Construction of teaching Materials for the "14th Five-Year Plan" Vocational Education Plan will be publicly released.Based on the new curriculum standards,the computer teaching and research team of secondary vocational school compiled the new textbooks,and changed the original curriculum textbook of computer major "Computer Application Foundation" to "Information Technology".According to the requirements of the new curriculum standards,the knowledge content of the 14 th Five-Year Plan textbooks is more advanced and rich.In the investigation of the current situation of the analysis of teaching materials for secondary vocational teachers,it is found that the teachers on duty have a high dependence on teaching materials in the process of course preparation,and have a strong subjectivity in the analysis of teaching materials.The application of objective matrix method in the analysis of teaching materials can not only solve the problem of teachers’ strong subjectivity in the analysis of teaching materials,but also help teachers flexibly choose teaching methods and sort out the teaching sequence in the teaching design.In this study,the author firstly analyzes the structure of the chapter "Understanding information system" in the new edition of Information Technology textbook of Higher Education Press based on the objective matrix method,forms the knowledge structure relationship diagram and makes a summary.Secondly,teaching design is carried out based on the analysis and summary of teaching materials.Although the duration of the lesson plan to be analyzed in this paper is set to three periods in the electronic resources of the Higher Education Press,the designed lesson plan can be shortened to two periods after applying the goal matrix method to the textbook analysis.If the teacher respectively applies the teaching design based on the target matrix method and the application of the teaching design in the electronic resources of the teaching materials,the students ’learning quality is equivalent,it can be a good solution to the actual secondary vocational information technology teaching work in the teaching of teaching content increase,the amount of class hours is limited.Finally,according to the problems proposed,the teaching contrast practice is carried out in the first secondary technical school of Changchun City,and the practice effect is analyzed.The research results show that the application of objective matrix method for teaching material analysis and teaching practice can help new teachers to improve classroom efficiency and ensure the quality of students’ learning,and effectively solve the problem of increasing the content of the new textbook,but the amount of class hours is not enough.In conclusion,this method is feasible.
