Investigation And Countermeasure Research On Classroom Teaching Status Quo Of Mathematics "Preliminary Algorithm" In Senior High School

Algorithm is the foundation of mathematics,applied mathematics and computational science.With the rapid development of science and technology,algorithms play a more and more prominent role in the society,and quickly integrate into every corner of daily life.A new chapter in senior high school mathematics is devoted to the discussion of "preliminary algorithm".As a newly added "preliminary algorithm",its teaching has formed a new research topic.This article embarks from the actual classroom teaching,based on the cognitive structure,constructivism learning theory,the theory of multiple intelligence,by the method of questionnaire survey,L and M two township middle school teachers and students by questionnaire investigation and study,through the interview method to understand the township middle school teachers' knowledge of the basic algorithm of "preliminary" situation,the questionnaire survey of teachers and students in algorithm teaching content knowledge about and attitudes,teaching practice and the importance of algorithm thought,want to be able to fully understand the villages and towns high school mathematics classroom teaching status quo of "algorithm preliminary" content,analysis of township high school mathematics "algorithm preliminary" classroom teaching present situation,analyze the existing problems,Put forward the corresponding teaching countermeasures,and according to the research results of "algorithm preliminary" teaching case design and analysis.Through questionnaire research and classroom teaching practice investigation and analysis,it is found that there are deficiencies in the preliminary classroom teaching of the algorithm :(1)students have difficulties in understanding and expressing the content of the algorithm;(2)The teacher does not pay attention to the "preliminary algorithm" teaching;(3)Lack of "preliminary algorithm" teaching resources;(4)Lack of relevant training for teachers and deviation of algorithm teaching requirements;(5)Teachers differ in the emphasis and difficulty of algorithm teaching,and there are differences in teaching emphasis;(6)"Preliminary algorithm" teaching content and teaching method is relatively simple..Based on the existing problems,the corresponding teaching strategies are proposed :(1)reasonable arrangement of the initial teaching hours of the algorithm;(2)The idea of gradual penetration algorithm;(3)Pay more attention to the teaching of circular structure;(4)Add computer-aided teaching tools;(5)Improve teachers' own quality;(6)Pay attention to the foundation and grasp the difficulty;(7)Research on joint information Technology group and regional teaching.According to the research results,four practical teaching cases were designed and analyzed with the basic concept of algorithm,cyclic structure,conditional statement and review of basic algorithm statement as the main content.
