Analysis Of Number Series Questions In The Senior High School And Study Of The Teaching Strategies

Mathematics curriculum standards for ordinary high schools(2017 edition)have been promulgated,marking the beginning of a new curriculum reform.In the new curriculum standard,it is required to carry out "four bases" and "four abilities",so as to promote the formation and development of "mathematics core accomplishment" of students.So under the new mathematics curriculum standards,what are the requirements for the sequence? How should senior high school series work and reach the new course standard requirement? This paper studies the numerical sequence teaching strategy of the national college entrance examination since the implementation of curriculum reform and combines it with the curriculum standards of high school mathematics(2017 edition).On the one hand,the research can enrich the existing teaching contents of the series.On the other hand,it puts forward an operable and effective teaching strategy of the series,which provides a better reference for the front-line teachers to carry out the series teaching.Paper combines with the college entrance examination test series,two aspects of students and teachers' research conclusions and the high school mathematics curriculum standards(2017 edition)for sequence requirements,Then,it puts forward new lecture and recitation teaching strategy,combined with the strategy design teaching case,three teaching cases,two of which are new teaching case,and recitation.They permate the mathematical literacy from different levels.To verify the teaching strategy effect,selecting two classes(one of the class is the experimental class,and the other one is the compared class).After the test,the scores of students are analyzed and concluded the results.The experimental classes' score is significantly higher than the compared classes,the experimental results show that the teaching strategies of improving student performance is useful.Through the study,the following conclusions are drawn:College entrance examination sequence of test questions pay attention to the examination of basic knowledge of the arithmetic(geometric)series summation formula of general term formula,in the basic amount of operation.By examining the basic knowledge of indirect examines student the basic idea of the method and calculating ability,logical ability and observation ability,the degree of test keep stable.The Basic questions and middle questions occuoy most paper,so the difficult areless than them.arts exam paper is simpler than the science,its own volume test overall somewhat difficult,the national curriculum volume and independent proposition in knowledge and mathematical thought between test will be repeated,National course standard volume(autonomous proposition volume)has been examined knowledge and mathematical thinking method,autonomous proposition volume(national course standard volume)will be examined again.In terms of the teaching strategy of sequence,the teaching strategy of the new teaching of sequence focuses on the forming process of concepts and formulas,we should pay attention to the derivation of formulas and properties in series;Pay attention to the teaching of arithmetic(geometric ratio)series of regular questions;"Taking this as the source" attaches importance to the teaching of examples and exercises in textbooks;Strengthen the judgment and proof of arithmetic sequence;Grasp the depth of teaching content.The teaching strategy of the series review course: strengthen the solution method of the general term formula and sum up problems of the series;Pay attention to the training of students' problem solving skills;Pay attention to the cultivation of students' observation ability;Focus on the students' easy to mix knowledge points and questions for induction,comparison and sorting;Pay attention to the teaching of mathematical thinking and method in series;Pay attention to various training and improve students' changeable ability.
