A Study On The Characteristics Of High Quality Mathematics Concept Teaching In Primary Schools

Mathematics concept is the cell of mathematics knowledge,and it is the bas is of the research,expression and application of all mathematical rules."Compuls-ory Education Mathematics Curriculum Standards(2011 Edition)" points out that the teaching of mathematics knowledge should pay attention to the "growth point" and "extension point" of knowledge.Mathematical concepts are not only regar ded as the foundation of mathematical knowledge and the core of mathematical t-hinking,but also can be seen everywhere in elementary school mathematics text books.Even the simple number "1" is a mathematical concept.As the cornerston-e of mathematical knowledge,mathematical concepts are the cornerstone of mathematical knowledge.At the same time,because the mathematics concept is abstra-ct,boring,complex and other characteristics,and the primary school students’ th-inking is still in the concrete image stage,which leads to the students’ learning of the mathematics concept is difficult,teachers also have a variety of mistakes in the teaching of mathematics concept.American educator James dobbins base in the practice of mathematics education research is put forward in view of the co-ncept of the learning process of APOS theory,there are a lot of researchers wil-l be introduced to our country the theory of primary and middle school mathem-atics teaching,the APOS theory suggests that the concept of the learning proces-s to undergo "activity","process","object" and "schema" four stages,correspond-ing mathematical concepts including concept is introduced,the concept of teachi-ng form,concept and internalization,four concept development process,the auth-or thinks that the APOS theory into the teaching of mathematical concepts,the elementary school mathematics concept teaching quality in class the teacher highl-ighted the outstanding features,It not only provides a new perspective for other teachers to teach mathematical concepts,but also follows the cognitive law of students’ learning knowledge.It not only allows teachers to have methods to follow in concept teaching,but also guides students to construct their own concept schema step by step,which is conducive to improving students’ thinking level and learning quality,so that students can better learn and grasp mathematical concepts.Therefore,this paper mainly adopts video coding analysis method,video obs-ervation method and text analysis method.From the perspective of APOS theory,this paper uses Nvivo 11 qualitative analysis software to conduct coding analysi-s on the videos of eight high-quality mathematics concept teaching courses in pr-imary schools,and explores the characteristics of high-quality mathematics conce-pt teaching courses in primary schools.The body is mainly divided into four pa-rts.The first part,APOS theory to primary school mathematics concept teaching value.This paper mainly expounds the value of APOS theory to primary school mathematics concept teaching from three aspects: APOS theory helps reveal the thinking process of students’ concept learning,APOS theory helps students mast er the basic characteristics of mathematics concepts,APOS theory helps improve students’ subject status in concept teaching.The second part,under APOS theory of primary school mathematics concept teaching quality class characteristics research design.This chapter first determines that the research object of this paper is the eight high-quality mathematics conc-ept classes selected from the high-quality classes that won the first prize in the "13th Session of Primary School Mathematics Teaching Reform Observation,Communication,Demonstration and Training",and transcribe the video into text in advance.Then the research tool is NVIVO11 qualitative analysis software and its application process.After the construction of video analysis framework and coding,the software was used to code the transcripts of eight high-quality lessons accor-ding to the "APOS Theory Based on the Analysis Coding Table of Primary Sch-ool Mathematics Concept Teaching Video Course".The transcripts were coded and analyzed from the horizontal(four stages of APOS theory)and the vertical(teacher behavior)directions.The third part is the video analysis of the high quality class of primary sch-ool mathematics concept teaching under APOS theory.Mainly will be encoded te-xt this material quality of code coverage data export software,for all the resear ch object of video coding reference point to carry on the summary,from APOS theory activity stage,process stage,object,scheme corresponding code coverage,the stages of the teachers’ behavior code coverage,the divine by tossing COINS at all stages of the length to the elementary school mathematics concept teachin-g on the basis of visual quality class a detailed analysis of video.The fourth part,the characteristics of high quality class of primary school mathematics concept teaching under APOS theory.This part summarizes all the te-acher behavior codes in the four stages,analyzes and summarizes the teacher be-haviors in the high-quality class videos from the four stages of APOS,and find-s that the characteristics of high-quality class in primary school mathematics con-cept teaching include the following aspects: in the activity stage,students are gu-ided to convert text and text,and concepts are introduced by relying on activities;In the process stage,thinking is exposed by asking questions,and mathematica-l language is transformed to form concepts.In the object stage,the character of questioning and clarifying is used to promote the internalization of the concept o-f symbolic representation.Schema stage guides students to link concepts and consolidate concepts with variations.
