| At present,the general problem of primary education is that it attaches importance to theory and a high mark,take exams as the ultimate indicator to measure and evaluate students.As a result,students pay too much attention to test scores in the learning process,ignoring the more important mathematical qualities such as speaking,thinking and cooperation in mathematical activities.To change the status,we should add activity courses in mathematics study.New curriculum standard points out that‘Synthesis and practical activities 'is a kind of learning activity which takes the question as the carrier and students participate in independently.In the learning activities,students will comprehensively use "number and algebra","figure and geometry","statistics and probability" and other knowledge and methods to solve problems.There are three objectives for the training of mathematics activity class:1.Cultivate students' basic skills necessary for social life;2.Consolidate the foundation of learning through mathematical activities,and connect knowledge to form a vein;3.Improve thinking goals through mathematical activities.At present,the literature of mathematics activity class in China generally focuses on theory rather than examples,with more strategies and fewer examples.In terms of implementation,there are still three major problems:the school does not pay attention to it,the teachers are short of time and experience,the students are lack of knowledge and exploration spirit,their participation is not high,and they are not easy to manage.Therefore,we should optimize and redesign the mathematics activity class,which is also a creative activity result.By providing high-quality teaching design and strategies,this paper hopes to better develop the activity class,deepen the students' awareness of mathematics application,and develop the core literacy of mathematics.After studying the present situation of mathematics activity class investigation at home and abroad,this paper determines the research ideas and methods.At first,the connotation of mathematics activity class is defined:take the problem as the carrier,and comprehensively apply the knowledge and methods of "number and algebra","figure and geometry","statistics and probability" to solve the problem in the life situation.The core process is "finding the problem,proposing the problem,analyzing the problem,solving the problem and reflecting".This paper makes clear the requirements of the new curriculum standard on the "synthesis and practical activities" section,and expounds the educational value of activity class:cultivate core qualities and build comprehensive talents;a new challenge and attempt to the traditional curriculum type;improve the efficiency of traditional class;develop a variety of mathematical skills;provide a variety of research materials to obtain innovative theories.Some basic theory of mathematics activity lesson is also listed.After that,this paper elaborates the specific principles of the implementation of mathematics activity class:review,flexible,adjust measures to local conditions,focus on the students,permeate mathematical thoughts.This paper enumerates and analyzes all the lesson contents,knowledge points and ability points of the "Fun of Mathematics" unit of Beijing Normal University edition.Then,combined with the characteristics of physical and mental development of primary school students and cognitive rules,the following four strategies can help students better carry out math activities:First,teachers accurately grasp the characteristics of mathematics activities;Second,the teacher chooses the mathematics activity class form flexibly;Third,teachers give activity class evaluation;Fourth,integrating information technology to help activity class;Fifth,home and school building mathematics activity class atmosphere together.Finally,according to the curriculum,This paper presents two teaching designs of mathematical activity class,namely "Points button" and "Drop test" and the summary. |
