The Exploration Of Mathematical Sequence Problem In Senior High School

Sequence is an important link between middle school mathematics and higher mathematics,it occupies a very important position in high school math and college entrance examination,and in higher mathematics,the limit thought of sequence has a more extensive application.In the 2010-2018 National College Entrance Examination Science Mathematics Volumes I and II,the examination of the sequence is relatively simple,and in 2019 mathematics volume I,sequence in the form of a new test appeared in public.Therefore,under this kind of reform,the series curriculum should be paid more attention to in the high school mathematics teaching.Teachers must deeply study how to grasp the difficulty of sequence teaching,and whether to provide students with some difficult problems.This article is based on the current high school mathematics education situation.By reading a large amount of literature,and studying high school textbooks,curriculum standards,examination outlines,and college entrance examination real questions,combining the past ten years of college entrance examination science math questions,the sequence problem is analyzed from four aspects: basic knowledge,core accomplishment,thinking method,sequence and mathematical culture.In view of the high school math sequence of some problems existing in the education and methods to cope with the change of the sequence examination form,the author makes the following suggestions based on the results of questionnaire and interview:When learning sequence,students should pay attention to :(1)regularly arrange the knowledge framework to form the knowledge structure;(2)with respect to complex question of sequence of Numbers,combined with what the teacher said,classify the question types in my own way;(3)improve self-study ability and develop good study habits.When teaching sequence knowledge,teachers should pay attention to :(1)repeatedly study textbooks and "curriculum standards",and strive to change from "teaching materials" to "using teaching materials";(2)pay attention to the process of generating knowledge and guide students to analyze problems;(3)focus on teaching methods;(4)pay attention to penetrating mathematical culture and developing interesting classrooms;(5)focus on cultivating students' self-study ability and improving their reading efficiency;(6)pay attention to the way of error correction,reduce students concentrated mistakes;(7)reduce guessing and increase the coverage of reviewing knowledge.
