Research On Junior Middle School Mathematics Proposition Teaching Based On Deep Learning

At present,with the rapid development of science and technology and the rapid updating speed of information resources,the country has put forward new requirements for the training and education of talents.The Mathematics Curriculum Standard for Compulsory Education(2022 edition)(hereinafter referred to as the "New Curriculum Standard")points out that students should not only learn knowledge and skills,but also learn to think independently,criticize and question,and develop innovative consciousness and other core qualities.Deep learning is an important way to cultivate and develop students’ core literacy,so it is necessary to realize deep learning in junior middle school mathematics class.In addition,junior high school is the critical period for students ’logical thinking training.The learning of mathematical proposition helps students’ ability to find problems,put forward problems,analyze problems and solve problems,and plays a unique role in promoting the development of students’ mathematical thinking.Therefore,it is very necessary to study the junior middle school mathematics proposition teaching based on deep learning.Since compulsory education mathematics curriculum reform in 2011,the teacher’s education teaching idea a fundamental change,and the corresponding teaching methods and behavior also efforts to realize the concept of curriculum,classroom teaching "full","teachers as the center" phenomenon is decreasing,but there are still some problems in the actual teaching: such as students’ learning thinking participation is not enough,group cooperation become a mere formality,teachers’ single questions,etc.In particular,the implementation of the "double reduction" policy has put forward higher requirements for teachers.In classroom teaching,students should pay more attention to the process,the cultivation of creative thinking,to the typical efficiency of homework design,to students’ ability to find problems and solve problems through independent inquiry.Therefore,this study takes mathematical proposition as the carrier,takes deep learning as the basis,and takes cultivating students’ mathematical core literacy as the goal,and actively explores the strategy of integrating junior middle school mathematical proposition teaching and deep learning,in order to provide specific and feasible practical operation path for first-line middle school mathematics teachers.This study adopts the literature research method,questionnaire survey,action research method of the junior middle school mathematics proposition present research,investigation of the literature and teachers and students put forward the corresponding teaching strategy,and the specific content of the teaching design,further education practice in the teaching implementation and test its effect.The specific study is as follows:First,I reviewed and reviewed the relevant literature of deep learning,mathematical proposition and mathematical proposition deep learning,and found that the existing studies mainly focus on their own independent research,in the distribution of study segments,more studies on primary school mathematics,less studies on middle or high school;more studies on mathematical proposition theory,and less empirical studies.Secondly,in order to understand the current situation of deep learning and learning of mathematics proposition teaching in the classroom,teacher questionnaire and student questionnaire are set up.Among them,the teacher questionnaire is compiled according to the five characteristics of deep learning and the questionnaire setting of existing researchers,and the student questionnaire was compiled according to the students’ learning habits and learning content.Some teachers and students of X Middle School in Luzhou City,Sichuan Province were investigated.After collecting the questionnaire,the current situation of mathematics proposition teaching and learning based on deep learning was obtained,and the reasons for the occurrence of teachers and students were analyzed respectively.Moreover,the corresponding teaching strategies are put forward by combining with the current situation of investigation,the five characteristics of deep learning,and the five aspects of proposition preparation,introduction,proof,application and reflection.Including proposition review preparatory strategy-association and structure;proposition introduction of situational strategy-activity and experience;proposition proof procedural strategy-essence and variation;proposition application holistic strategy-migration and application;proposition evaluation reflective strategy-value and evaluation.Finally,according to the five links of the teaching of proposition teaching and its teaching strategy.The teaching design selects the typical content of junior middle school mathematics,which is the property theorem course-"triangle inner Angle and theorem",judgment theorem course-"judgment of equal triangle-SAS" and formula course-"complete squared formula".According to the teaching design,the classroom teaching implementation is carried out,through the effect analysis of students ’classroom performance,students’ conversation after class,and the test effect.
