The Research On The Teaching Of Algorithm Preliminaries Under The New Curriculum

"Ordinary high school mathematics curriculum criterion(experimental)"contains "algorithm preliminaries",which is in the curriculum of five modules in mathematics 3, algorithm becomes new additions to the curriculum.Algorithm teaching will challenge to the traditional mathematical teaching of high school.Combing the current new ideas of mathematics course reform,this paper,vie literature study,surveys and interviews, analyses the requirements of the course "algorithm preliminaries" to the students and teachers,and makes an analysis on the problems students encounter in their study in algorithm as well as issues existing in the teaching of this course,thus exploring the teaching of "algorithm preliminaries".This paper outlines the concept,characteristics and formulation of algorithm,and then analyzes the connotation of it.It is for the first time that "algorithm preliminaries" becomes the compulsory course of mathematics in senior high,so there emerges some problems during the practical teaching.This paper makes a deep analysis on its course objective.The objective of "algorithm preliminaries" is to help students deal with problems with algorithm thinking and cultivate a variety of mathematics thinking to provide knowledge and ability preparation for their future development in this area.It is conducted through four stages and levels.This paper makes a survey on the current teaching situation of "algorithm preliminaries" of two schools,from which the main problems are as follows:First,on the students' part,they do not understand the algorithm sufficiently.Second,the appliance of algorithm in computer and other related mathematics knowledge is not enough.Third, the support teachers obtain in their teaching is far from enough.Forth,there is some misunderstanding in the teaching ideas of teachers.To sum up,there are various reasons, including the course itself,teachers and students.Therefore,in accordance with what is revealed in the survey,this paper gives some suggestions on how to be prepared for the teaching activities,makes an analysis on how to increase students' interest in study,as well as the strategies for the key and difficult points and how to handle them.At last,this paper also elaborates students's computing practice,the variety and enhancement of algorithm,compiling of the textbook plus the development of course resources.
