Teaching Research Into Algorithm Preliminary In Senior High School

Algorithm knowledge has a long history and is widely used in daily life.Nowadays,with the rapid development of information technology,people attach great importance to the initial knowledge and ideas of algorithms.In order to keep pace with the development of The Times,in China's new curriculum reform in 2003,for the first time,"algorithm preliminary" knowledge into high school mathematics compulsory course 3.Algorithm teaching with a new face appeared in the high school mathematics curriculum system,although so far have after several rounds of teaching practice,knowledge and ideas of teaching but algorithm did not reach the level of highly skilled,education goal is not effectively implemented,so the algorithm teaching situation needs to be further improved and perfected.Based on the previous research results,this paper analyzes the question type structure of the algorithm question in the college entrance examination in recent years,as well as several classical algorithm teaching cases.Using literature method,questionnaire survey method and interview method,case analysis,etc.,the algorithm of "preliminary" teaching and practice status investigation and analysis,find out now "algorithm preliminary" some of the problems existing in the teaching activities.In view of these problems,combined with relevant teaching theories and teaching cases of education,this paper puts forward some Suggestions of "algorithm preliminary" teaching for reference,aiming at serving teachers and students in teaching.
