| Nowadays,the demand for the optimization of teaching mode in the field of education is constantly increasing,so the research of different educational modes has been developing rapidly.Among them,the teaching mode of "three sections and five rings" has been gradually adopted due to many advantages."Three sections and five rings" refers to three periods and five links.It is a teaching mode that emphasizes learning,teaching,students’ thinking and inquiry,and promotes knowledge construction,which is consistent with the connotation of emphasizing thinking and flexible application of the current new college entrance examination reform.However,at this stage,there is little research on this model,both abroad and at home,specifically for the study of mathematics subject is insufficient.How does the implementation of this model in the classroom affect the students?Will it cause students to fail to adapt?Especially in the context of the college entrance examination,will it have a positive or negative impact on students’ performance?These are the questions to be considered when deciding whether this model is implemented and how it is implemented.Now for the problem that this mode is less applied in practical teaching activities,we take the teaching of the third chapter "the Concept and Nature of functions" as an example,design the teaching plan in line with the teaching principle of "three sections and five rings" and apply it to classroom teaching.Then,we use the unified test questions of the school to examine the students in the class who did and did not use the model twice,and judge the impact of this teaching model on the math scores of high school students,by analyzing the average number,variance,score segment and other data of the collected grades.Based on the conclusions obtained in this study,this model can be extended to the teaching of other content if it is conducive to improving the performance of the unit.Instead,we can analyze the reasons and improve this mode appropriately if it has an ineffective or negative effect on improving the performance of the unit. |
