Research On Teaching Design Of Senior High School Mathematics Concept Based On "Question String"

The fundamental purpose of instructional design is to apply theoretical knowledge to practice and guide practice with theory,so as to build an effective teaching system.Mathematical concepts are the foundation of mathematical knowledge and the cornerstone of building students' thinking activities,it plays a carrier role in the transmission of mathematical ideas and methods.Therefore,in order to improve the effectiveness of high school concept teaching,this paper puts forward a research on teaching design of high school mathematics concept based on "problem string".The author starts from the new curriculum concept,first of all,through the study of literature,the definition of mathematical concepts,problem series and other related concepts are defined,on the basis of sorting out and analyzing the current research situation at home and abroad,the thinking and structure of this paper are determined.Secondly,based on the research and analysis of the theory and design principles of question string and instructional design,combined with the questionnaire survey of teachers,design two high school mathematics concept teaching designs based on question string,and apply them to practice.Finally,according to the relevant observation scale to analyze and evaluate the teaching practice,draw a conclusion.The practical results show that:the teaching design of mathematical concept based on "question string" is applied to practical teaching,not only can arouse the enthusiasm of students,help students to build a holistic understanding of knowledge,and it can promote the level of students' problem exploration,It is hoped that the concept teaching design based on problem string proposed in this paper can provide some reference for high school mathematics teaching.
