Experimental Research On Parallelogram Teaching In Junior Middle School Based On The Concept Of "Three Education"

The core of the new round of mathematics curriculum reform lies in cultivating students' core mathematical literacy.Under such a background,Professor Lv Chuanhan put forward the educational concept of "teaching thinking,teaching experience and teaching expression"(referred to as "three teachings"),hoping that through classroom teaching,students can promote student development,achieve classroom transformation,and thus cultivate core elements.Raise.This study takes teachers as the teaching leader and students as the teaching subject,and explores how to connect the concept of "three religions" with the parallel quadrilateral classroom content of junior high school,so as to promote students to take the initiative to think,gain insights and be good at expression in learning.Based on existing research,the literature research method is adopted to explore the principles and strategies of applying the concept of "three religions" to practical teaching,and implement it in the teaching content of parallelograms in junior high schools.Experimental research methods are used to explore the differences between teaching and conventional teaching under the concept of "three religions",and at the same time,the parallelograms are measured.The test paper and the results of the student questionnaire are analyzed to pay attention to the changes in students' academic performance,learning emotions and mathematical expression.First of all,according to the psychological theories of "recent development zone","from middle school" and "self-efficacy",the relevant textbooks are analyzed at the same time,and based on relevant literature and the teaching experience of front-line teachers,three basic teaching principles under the concept of "three religions" are summarized: 1 pay attention to students and reasonably set goals;2 Understand the textbook and systematically plan the classroom;3 Pay attention to emotions and promote generative learning.Based on this teaching principle,three main teaching strategies are proposed,namely: 1 problem-oriented;2 activity-oriented;and 3expression to promote development.Secondly,the corresponding test papers and questionnaires are designed,and the two classes of a school in Yunnan Province are selected as the control class and the experimental class respectively.The experimental class adopts the teaching based on the concept of "three religions",the control class adopts traditional teaching,and uses SPSS software to analyze the test papers and questionnaires.The research results of the test paper show that teaching under the concept of "three teachings" can help students better master parallelogram knowledge and effectively improve students' academic performance.The analysis results of the questionnaire survey show that in classroom teaching under the concept of "three religions",students can independently and layeredly build a knowledge framework,effectively develop students' expression ability,cultivate their core literacy,and promote the development of good habits of summary and reflection.In terms of learning emotions,most students are willing to accept and like numbers.Learn,actively internalize knowledge into your own experience,know what you do,and internalize it into your heart.In terms of expression,from willingness to communicate to active communication,turn thinking into language,generate a collision of thinking in expression,and enhance students' expression ability.The teaching principles and teaching strategies of parallelograms in junior high schools based on the concept of "three religions" proposed in this paper can be migrated and popularized to other teaching topics or contents.I hope this study can provide reference for front-line teachers to carry out teaching under the concept of "three religions" and enrich the research of the concept of "three religions" to a certain extent.
