Research On The Lead-in Of Senior High School Mathematics Course

High school mathematics curriculum advocates active,courageous and exploring ways of learning,improving students' thinking and developing students' application ability.In order to achieve this goal,warming up and leading in becomes extremely important.Although some teachers have made some progress in the curriculum reform,some teachers focus on lead-in yet are not in accordance with students'aptitude.Therefore,the spirit of the new curriculum standard has not been spread on real significance.In September 2016,the new "core quality of middle school students" became the key to curriculum reform.After the core literacy was put forward,the future teaching will pay more attention to setting a problem context.It is of significance to create a teaching situation,lead-in and curriculum design which are conducive to the students develop core literacy.We need to think about what kind of lead in cultivates the students' interest most,enables students to fully develop themselves and makes them fully aware of the nature of mathematics and think and solve the problem actively.To meet this requirement,the lead-in of a simple problem context is far from enough.We must design different lead-in methods according to the different subjects and students.Only in this way can students improve their autonomy,enhance their love for mathematics,and develop themselves.This research mainly adopts the comparative literature method,teaching practice and questionnaire survey.Through the comparison of the students' learning effect and the teaching practice,we can get a better lead-in case.The questionnaire draws the relation between the students' interests and the way lead-in is set.The relation between interest and learning effect is obtained through tests.The conclusion of this paper:mathematics teaching atmosphere will affect students' interest in learning,and the leading-in will affect students' mathematics learning atmosphere.A good leading-in can stimulate students' interest in learning mathematics,improve learning efficiency,attract their attention.In the class with a better lead-in students are more interested in math,get higher grades and higher enthusiasm in learning mathematics.For the leading-in of different teaching topics,different methods not only can arouse the students' interest in learning but also can improve the students' mathematical literacies,such as mathematical thinking,logical reasoning,mathematical modeling and visual imagination,which helps them get better development.So teachers must design the classes according to the different class types,topics and students.It has a great effect on the class efficiency,the students and teaching outcomes.Once the students get used to this kind of teaching,they will be more interested in mathematics.If teachers guide properly in this part,students can learn and innovate spontaneously.
