Research On Situation Creation In Mathematics Concept Teaching In Senior High School ——Take "Basic Elementary Function(?)" As An Example

The 2017 senior high school mathematics curriculum standard proposes to take the development of students' subject core literacy as the goal,and encourage the creation of reasonable and effective situations,so as to gradually inspire and guide students to grasp the essence of mathematics.Situational creation is not only an important foothold for the formation and development of discipline core literacy,but also the key to cultivate students' comprehensive ability.Therefore,the principles,strategies and ways of creating situations are worthy of further study.In the current mathematics concept course,Under the influence of the traditional teaching mode,most teachers ofen give the concept directly,and then achieve the purpose of consolidating the concept through the way of " sea topic tactics".Although a few teachers will use situation creation,the introduction of new courses is too focused on the use of teaching materials,and lack the ability to create situations independently.For a long time,it has seriously hindered the development of students' thinking and innovation ability.Therefore,the research on situation creation has important value and significance to improve teachers' professional quality and students' ability.This essay comprehensively adopts the methods of literature analysis,interview,questionnaire and educational experiment.Firstly,the author defines the relevant concepts and theoretical foundations on the basis of reading a large number of domestic and foreign literature on situational creation.Secondly,through teacher-student interview and questionnaire survey,we can understand the current situation of situation creation in the teaching of basic elementary function(I)concept and the difficulties of students' learning concept.Thirdly,combined with cases,this thesis summarizes the principles and strategies of situation creation in the concept teaching of basic elementary function(I).Based on this,according to the situation creation theory and APOS concept teaching theory,under the guidance of core literacy,this thesis integrates the general process of situation creation in concept teaching.Secondly,from the perspective of paying attention to situation creation,the teaching cases of "exponential function concept" are designed from the three stages of pre class,in class and after class.In order to verify the effectiveness of situation creation,the teaching practice is carried out on the students of the experimental class and the control class by using the educational experiment method,and the experimental results are analyzed from the three aspects of classroom observation,pre-test and post test scores and student interview.Finally,the experimental conclusion is drawn: paying attention to the teaching of situation creation is conducive to promote students' concept learning and mobilize the classroom atmosphere.Finally,based on the above theoretical and practical research,analyzes the shortcomings of this thesis and gives the conclusions and prospects.I hope that this thesis can provide strategic suggestions for the creation of situation in concept teaching to the majority of front-line teachers.
