Research On Teaching Strategy Of Classification Of Mathematics Knowledge In Senior Middle School Based On Information Technology Software

In senior middle school,the content of mathematics and the types of mathematics knowledge become more and more.It is a concerned problem to choose the appropriate teaching strategies to enable students to master different types of knowledge and understand the important and difficult points of knowledge deeply.With the rapid development of science and technology,the hardware and software enter the classroom which enrich the classroom teaching methods.According to different types of knowledge,choosing appropriate information technology software can improve students’ knowledge framework and cultivate mode of mathematical minds,which is significant to improve classroom teaching effectiveness and teaching quality.With the help of multimedia learning theory and generalized knowledge classification theory,this thesis analyzes the current situation of multimedia teaching in senior high school mathematics classroom by adopting questionnaires,interviews and other methods,and discusses the teaching strategy of combining information technology software with knowledge classification theory of mathematics.Firstly,we design a questionnaire about information technology software and knowledge classification of mathematics to investigate the high school students’ cognitive level,and analyze the reliability and validity of the questionnaire by the SPSS.Then,a semi-structured interview outline is designed to understand the students at different levels in detail.According to the analysis results,senior middle school mathematical knowledge is divided into the declarative knowledge,procedural knowledge and strategic knowledge.For the declarative knowledge,the teaching strategies of visualization of mathematical concept,dynamization of geometry and visualization of data processing are proposed.For the procedural knowledge,the teaching strategies of demonstration of algebraic operation,anatomization of geometric model and functionalization of progression induce are proposed.For the strategic knowledge,the teaching strategies of externalization of function limit,essentialization of equation parameters and exploring complex models from multiple perspectives are proposed.At last,the corresponding information technology software-assisted teaching strategies are showed for the different types of knowledge content.The teaching cases show that the knowledge classification teaching of mathematics based on information technology software can enrich teaching strategies,diffuse students’ minds,cultivate intuitive imagination and improve cognitive level.
