Research On Evaluation Index System Of Junior High School Theorem Teaching Design Based On Core Literacy

Learning mathematical theorems is one of the important ways to cultivate mathematical thinking.The purpose of teaching design of junior high school theorems is to let students gradually cultivate their core literacy of mathematics in the process of exploring the generation of theorems,proving theorems and solving problems by using theorems.So what kind of teaching design of junior high school theorems is a qualified teaching design? Therefore,from the perspective of core literacy,it is the core issue of this study to construct a reasonable,reliable and diagnostic evaluation index system for teaching design of junior high school theorems based on core literacy.In view of this research problem,first of all,the literature is consulted,and the evaluation index system of teaching design of junior high school theorem based on core literacy is preliminarily constructed.Second,consult experts on the necessary degree of indicators at all levels,complete the revision of the evaluation index system;Third,consult experts on the importance of indicators to determine the weight value of indicators at all levels;Finally,two front-line teachers independently evaluated 10 teaching designs of junior high school theorems to test the diagnostic function of the evaluation index system.The relevant research conclusions are as follows :(1)The evaluation index system of teaching design of junior high school theorems based on core literacy includes 7 first-level indicators,18 second-level indicators,and 7 third-level indicators under the second-level indicator "teaching process".Among them,the first-level indicators are: "teaching material analysis","learning situation analysis","teaching objectives","teaching important and difficult points","teaching strategies","teaching process" and "teaching evaluation".Secondary indicators are: "Understanding theorem background" "clear structure theorem" "clear theorem value" "the concept of knowledge to understand students" "understand psychological characteristics of the students mathematics study" "suit curriculum" clear "target" "clear core literacy cultivation target" "focus on clear" "clear" difficulties "accord with cognitive law" breaking "difficult point" "goal" "the discovery of the theorem","the proof of the theorem " The application of the theorem " " focus on process evaluation " " focus on outcome evaluation ".The three-level indicators under the second-level index of " teaching process " are: " creating appropriate situation "," smooth and natural inquiry process "," clear knowledge structure "," clear logic of proof "," diverse methods of proof "," appropriate selection of exercises "," integration of exercises explanation into teachers' understanding" and "effective cultivation of mathematical thinking".(2)Analyze the weight value of expert indexes with AHP,and get the weight value of evaluation indexes at all levels.Among the first-level indicators,the weight value of "textbook analysis" is 11.83%,"learning situation analysis" is 8.8%,"teaching objectives" is 17.61%,"teaching important and difficult points" is 11.12%,"teaching strategies" is 15.33%,and "teaching process" is 32.43%.The weighted value of "teaching evaluation" is 2.88%.In the second-level indicators,the weight value of "clear goal" was the highest at 6.65%,and the weight value of "process-oriented evaluation" was the lowest at 1.43%.(3)The evaluation index system of junior high school theorem teaching design based on core literacy has good reliability and validity,and has diagnostic function.The two experts conducted a consistency test on the scores of 10 junior high school theorem teaching design,and the scores of the two experts presented a significance level of 0.01,indicating that the implementation reliability of the evaluation index system of junior high school theorem teaching design based on core literacy is good,and it has a certain diagnostic function.
