A Study On The Drop-anchor Teaching Strategy Directed To The Mathematical Key Competence In Primary School

Under the general trend of international education reform,the educational aim of every country has gradually changed from mastering knowledge and skills to cultivating key competence.The cultivation of students’ key competence should be carried out in the subject teaching.The mathematical key competence is an important component and explicit form of the core quality of mathematics,an important goal of the current basic education reform,and also the main line of mathematics classroom teaching.In the course of teaching,only by setting the goal on the cultivation of the key competence of mathematics,can the core quality of mathematics be improved.At present,there are several problems in the cultivation of primary school mathematical key competence in our country: the students’ operation competence is not strong,the reasonable reasoning competence is weak,the lack of mathematical modeling experience,the geometry intuition consciousness is not strong and the problem solving competence is weak.Anchored instruction is a student-centered teaching method,which allows students to construct knowledge independently in the process of self-exploration and cooperative communication,and conforms to the idea of new curriculum reform.Anchored instruction was initially applied in mathematics field,but there are few researches on anchored instruction in mathematics subject in China,especially in elementary mathematical teaching.Under this background,this article changes the traditional classroom teaching method,taking the promotion of students’ competence as the teaching goal,carrying on the research to the anchor teaching strategy which points to the students’ mathematical key competence.First of all,an anchored instruction model is constructed on the basis of related theories,and teaching experiments are carried out by taking the teaching of graphics and geometry as an example,to test the effectiveness of anchored instruction.Collect data,analyze the experimental results,find out the problems in anchored instruction and analyze the causes of the problems.Finally,put forward the anchored instruction strategy to the key competence of mathematics in primary school.The main contents of this paper are divided into the following parts:The first chapter is the summary part,which expounds the concept and classification of the mathematical key competence in primary school,and the characteristics of anchored teaching.This paper expounds the concept of anchored instruction which points to the mathematical key competence,and analyzes the feasibility and necessity of it.The second chapter is the theory foundation part,from the perspective of anchored teaching theory and Van Hill’s geometric thinking level theory,it explains how to conduct anchored teaching in the field of graphics and geometry.In the third chapter,under the guidance of the theoretical foundation,taking graphics and geometry as an example,the author constructs the anchored teaching strategy system,including the analysis of the curriculum objectives,the analysis of the curriculum contents.At last,the teaching process of anchoring is described in detail: anchoring contextualization;anchoring visualization;anchoring self-determination;un-anchoring cooperation;thinking integration.The fourth chapter is the design and implementation of the anchored teaching experiment,which points to the key competence of mathematics.The object,purpose and tool of the experiment are analyzed.Finally,the area of the parallelogram is taken as an example,carrying on the teaching case design.The fifth chapter carrying on the statistics and the analysis to the experiment result has tested the validity of the anchored instruction.Through the data analysis discovered that the anchored instruction is helpful to promote the student ’s many kinds of mathematical key competence as well as the geometry thought level,combined with observation and interview,find out the problems in teaching and the attribution of the problems.The sixth chapter puts forward the anchoring teaching strategy which points to the mathematical key competence in primary school from six aspects: When anchoring,creating situation to extract information and help students’ intuitive imagination;when anchoring,using visual teaching to ask questions,to cultivate the ability of mathematical abstraction;to promote cooperative learning and enhance the ability of logical reasoning when studying the anchor;to solve real problems with new knowledge and strengthen the ability of mathematical modeling when un-anchoring;to actively carry out teaching reflection when thinking about the anchor and provide teaching guarantee in an all-round way;finally,establishing a multi-evaluation system to improve the key ability of individual mathematics.At last,it is the conclusion and prospect of the research.Firstly,it summarizes the whole process and the conclusion of the research,and reflects the deficiency of the research.Finally,it looks forward to the future improvement direction.
