Teaching mode,which is the key point of the research of the group activities,is the eternal subject of educational research.What’s more,it is the key to the teaching quality.From the successful example of the weak schools such as Yangsi High School,Du Lang Kou Middle School,Hengshui High School,innovative teaching model can make them "at the great rebirth,vigorous development",and set a good example to us.It is known to us that success can not be copied and creating or selecting a school teaching model is constrained by a number of conditions.At the same time,with the development of society and economy,more and more investment in education,and "education to promote development",it is important to improve the quality of teaching.In order to improve the quality of mathematics teaching,the mathematics teaching mode of“Three cases one history”is carried out in District D of Zhaoqing in the middle and primary schools with the leadership of the math research office.In this passage,the teacher choose 300 junior middle school students in Zhaoqing × × high school as the objects of investigation.Among them,the teacher has a questionnaire survey about their learning.The survey shows that many students is lack of self-confidence,self-learning ability,innovation ability and mathematics accomplishment.This passage aims to carry out “Three cases one history” in the experimental class with the teaching mode of mathematics to solve the problems.If it works,we can promote it.In this passage,the "self-study tutorship teaching mode" and "stratification teaching mode"to do a detailed literature review,from constructivism,humanism and the theory of the zone of proximal development,based on “Three cases one history” of mathematics teaching mode of connotation and forms,lists the teaching material writing requirements and match with concrete examples,the maneuverability is strong.The teacher regard the new version of the compulsory education junior middle school text book the section as an example and design a "new","geometry","recitation" teaching examples.The passage is about how to carry out “Three cases one history” of mathematics teaching mode for specific details.The teachers carry out the experiments among the three grades.Each grade has one experimental class for “Three cases one history” teaching pattern,the other class for the traditional teaching mode that in comparative classes.After one semester,the teacher regard the final exam questions as the after test,compare the mid-term exam with the final exam’s scores and analyze the experimental results.At the same time,the teacher makes a middle period survey among the students from the experimental class and have an interview with the teachers and students of class 6.Taken to illustrate the"Three cases one history of junior middle school mathematics teaching:(1)returned to the students’ classroom sovereignty;(2)enhance students’ passion for learning mathematics;(3)students get sustainable development.From the result,it is concluded that the teaching mode of “Three cases one history” plays a role in the students’ interest in learning,mathematics result,self-learning ability,the improvement of maths.As a result,it is worth promoting. |
