Research On The Current Situation Of The Class Introduction Of Mathematics In Senior High School

The first link of mathematics class is introduction.Although it takes little time,it plays an important role in helping teachers complete teaching tasks,achieving teaching objectives and improving teaching quality.With the rapid development of the times,high school mathematics teaching has been also constantly updating and improving under the situation of the reform of curriculum.Class introduction has become a research trend in this field.Therefore,it is of great significance to investigate and evaluate the situation of mathematics class introduction in today's high schools.This thesis uses Constructive Learning Theory,Antecedent Organizer Theory,Cognitive Theory and the methods of literature research,questionnaire survey,class observation and statistical analysis in order to investigate the current situation of class introduction implementing in the senior high schools' mathematics classes and the factors affecting the introduction.According to the relevant teaching principles in the literature,combining with the actual situation of the school,this research formulate a evaluation measurement table from five aspects and a questionnaire for students and teachers in a senior high school to investigate the current class introduction situation in mathematics classes.This thesis analyzes the collected data with Excel and SPSS and get the main conclusions:Through the comparative investigation between the school class and the network open class teaching the same mathematics content in a senior high school,it is concluded that:(1)The school class and the network open class are basically identical in introduction time,principle and the students' participation.There is a gap in introduction form,method and the function.The network open class is better;(2)Teachers in school class use single introduction method aiming at assisting the teaching content,which omits the class atmosphere;(3)The introduction of online open class pays more attention to students' interest and promote mathematics culture while the counterpart in school class tends to set clear learning objectives as a result of the weak professional ability,lack of understanding students,and the heavy pressure from teaching tasks.Through the questionnaire on students in different grades and teachers at different levels,according to the difference,correlation and regression analysis,it is found that:(1)The higher the students' grades are,the more dissatisfied with the teachers' use,length of time and atmosphere of the introduction.The responses in sophomores are more satisfied thanfreshmen and seniors;(2)Teachers with little experience and low professional titles have difficulties in implementing introduction.Teachers with more experience and high professional titles are lack of understanding of the introduction;(3)The teachers' understanding of the principles and functions of the introduction is positively related to the use of the introduction.This is closely related to the implementation of the new curriculum reform policy,unchanged understanding of the teachers and the lack of experience.In view of the statistical results and existing problems of the introduction in senior high school's mathematics classes,this thesis puts forward the following suggestions:(1)According to the theoretical basis of the introduction,design class introduction for different students;(2)Improve the old teachers' educational concept and understanding,strengthen teaching ability and the quality of young teachers,and provide targeted suggestions of class introduction and practical and efficient training in teaching;(3)Strengthen teachers' mastery of the role and principles of class introduction,and improve the utilization rate of the introduction.
