Status Investigation And Design Research Of "Question String" In High School Mathematics Teaching

With the reform and development of the new curriculum in recent years,the Ministry of Education has been advocating the use of new teaching and learning methods in order to optimize some "stubborn diseases" under the traditional teaching mode.The General High School Mathematics Curriculum Standards(2017 Edition)attaches importance to the cultivation of students’ abilities,advocates multiple learning methods,and attaches importance to students’ awareness of questions and innovation.Question is the heart of mathematics.,as a new teaching mode,"question string" teaching,which focuses on questions,takes questions as the core,takes inquiry as the means,and aims at solving questions,seems to be more able to meet various needs and pursue goals.However,in high school mathematics "question string" teaching,due to various factors,the use of "question string" has been unsatisfactory,making "question string" not play its due teaching effect.In addition to teachers’ super-high teaching quality,"question string" teaching requires students to have a certain knowledge base and ability literacy,as well as a certain thirst for knowledge and exploration spirit.Based on this situation,this paper investigates the current situation of high school mathematics "question string" in high school teaching and conduct research on the design of high school mathematics "question string".This study adopts a combination of theoretical discussion and practice,using literature analyse method,questionnaire survey method,interview method,case analysis method and classroom observation method,the research mainly includes the following contents: First,the domestic and foreign literature related to "question string" is analyzed and summarized to understand the current research status of "question string" and lay a theoretical foundation for this research.Second,using the questionnaire survey method and interview method to randomly investigate some teachers and students in two high schools in Harbin,combined with case analysis method and classroom observation method to assist the questionnaire survey,understand the current use of "question string" in high school mathematics teaching.Third,the attribution analysis of the existing questions of high school mathematics teaching and the optimization strategy are put forward.Fourth,conduct research on the design of high school mathematics "question string".Fifth,for three different class types,give specific school mathematics "question string" design examples.According to the data obtained from the current survey,three problems of "question string" in senior high school mathematics teaching are summarized: poor use of "question string",insufficient "question string" design ability,and ineffective teaching effect of "question string".The attribution analysis is carried out on the three aspects and the optimization strategies are proposed.(1)Strategies to optimize the use of "question string" : read relevant literature to strengthen the understanding of the essence of "question string";Call for the use of "question string" to enhance the importance of teachers to "question string" teaching.(2)Strategies to improve the design ability of "question string" : be familiar with the design process and principles of "question string";Realize the importance of self growth and realize lifelong learning;Strengthen the communication between teachers and learn from each other;Carry out academic exchange activities related to "question string";Hold the "question string" design competition;Carry out "new" and "old" teacher cooperation and assistance activities.(3)Strategies to optimize the teaching effect of "question string" : "question string" flexibly applies to the classroom;Make good classroom records and improve the teaching reflection of "question string";Reasonably allocate thinking time to ensure students’ full thinking;Ask questions for all students and pay attention to individual differences among students.Based on the conclusions of the current survey,and on the basis of literature research,conduct research on the design of high school mathematics "question string",propose :(1)The types of "question string" : progressive "question string",parallel "question string" and radial "question string".(2)The design process of "question string" : preparation before "question string" design-"question string" design-"question string" teaching-summary and reflection.(3)The design principles of "question string" : purposive principle,heuristic principle,hierarchical principle and scientific principle,focus on student subjects principle.(4)The design strategies "question string" design strategy: pay attention to the creation of situations and increase the sense of "existence" of "question string";The design of "question string" should pay attention to the students’ recent development area;The design of the "question string" should focus on the teaching content; The design of "question string" should arouse students’ cognitive conflict.
