Research On Teaching Design Of Trigonometric Function Unit Based On ADDIE Model

The "Mathematics Curriculum Standards for General High Schools(2017Edition)" points out that the core literacy of mathematics is the concentrated expression of the objectives of the mathematics curriculum,and is a comprehensive reflection of the thinking quality,key abilities,emotions,attitudes,and values with the basic characteristics of mathematics.It is gradually formed and developed in the process of application and application.So,how to implement the core literacy of mathematics?Research in the educational field shows that unit teaching is an effective way to implement the core literacy of disciplines.In order to ensure the effect of unit teaching,unit teaching design is required.Due to the long-term teaching design of the first-line mathematics teachers,there are certain difficulties in the design of unit teaching.This paper builds a mathematical unit teaching design model based on the ADDIE model,and takes the trigonometric function unit as an example to apply the constructed model to improve The problems existing in the teaching design of the trigonometric function unit are discussed,and the process of the teaching design of the mathematics unit is improved,which provides a theoretical reference for the front-line mathematics teachers to carry out the unit teaching design.The research methods adopted in this paper include literature analysis,questionnaire survey,interview,and action research.First of all,through the analysis of domestic and foreign mathematics unit instructional design and ADDIE model research,it is found that ADDIE model is suitable for mathematics unit instructional design.At the same time,there are few studies on the teaching design of trigonometric function units in academia,and there are few studies on the teaching design of trigonometric function units based on the ADDIE model.Secondly,based on the existing research results,the author conducts a questionnaire survey on the current situation of trigonometric function learning among 168 students in different classes in the second grade of the internship school,and conducts interviews with front-line mathematics teachers on the current situation of trigonometric function teaching,and summarizes the survey results and makes attribution analysis.Then,based on the survey results and existing research results,a math unit instructional design model based on ADDIE model is constructed.The constructed model includes five stages of analysis,design,development and implementation.Finally,combined with the current situation of trigonometric function unit teaching and learning,based on the ADDIE model,the trigonometric function unit teaching design was carried out,and the design was implemented in the first and third classes of the practice school.In order to effectively evaluate the trigonometric function unit teaching design,Taking the first and second classes of senior high school as the control class,the traditional teaching form is adopted,and based on the results of students' observation during teaching,the analysis results of trigonometric function test papers,the results of the questionnaire survey on the current situation of trigonometric functions,and the results of interviews with teachers listening to the class,evaluated the teaching design of the trigonometric function unit.From the perspective of ADDIE model and mathematics unit teaching design,combined with the current situation of trigonometric function unit teaching and learning,the author constructs the mathematics unit teaching design mode,and studies the trigonometric function unit teaching design.The main problems of this paper are as follows:Question 1: Is the ADDIE model applicable to the instructional design of mathematics units?Question 2: What is the teaching design mode of mathematics unit based on ADDIE model?Question 3: Is the trigonometric function unit teaching design based on the ADDIE model beneficial to students' learning?The main conclusions of this study are:Conclusion 1: There is a strong applicability between the ADDIE model and the teaching design of the mathematics unit.Conclusion 2: The mathematics unit instructional design mode based on the ADDIE model includes five stages,and each stage contains different contents of the mathematics unit instructional design.Conclusion 3: The trigonometric function unit teaching design based on the ADDIE model can improve students' performance to a certain extent,help to correct the attitude of students to learn trigonometric functions,and enable students to grasp the knowledge of trigonometric functions as a whole,and feel the mathematical ideas contained in trigonometric functions.It cultivates students' ability to analyze,solve,discover,and pose problems,which is conducive to improving students' core literacy of mathematics and enabling students to develop in an all-round way.
