| With the development of the times, more and more talents with capacity are urgently needed. As a first-line math teacher, it's quite important to hold a good grasp of teaching mathematical concepts, which is do help to train students'mathematical ability. For a long time, contrast with conceptual understanding and mining, the score and exercise have been put on an more important place. Therefore, as a glorious educator, I consider it necessary to optimize the teaching of mathematical concepts and make my contribution as hope.In this thesis, some reference is used as basis to compare with the status of the mathematical concepts teaching at home and abroad. By comparison, it's easily to find that nowadays schools do not put emphasis on the teaching of mathematical concepts, and even some teachers proposed to lighten the concept, which is bound to lead to the conceptual confusion, and will not good for the mathematics learning. On the basis of the investigation, firstly, the thesis has bring up the issues such as lightening the mathematical concepts, diluting and injection concepts, the imperfect evaluation system, lack of reseaches, etc.Secondly, this thesis set Ausubel Theory, Constructivist Theory, Vygotsky Educational Theory and Modern Theory of Emotional Education as the basis to reseach the significance and use of teaching mathematical concepts. Besides, it also combines Case Study Method, Survey Sesearch, and personal years of teaching experience to explore the concept of teaching strategies of high school mathematics and put forward some opinions. Mathematics Teaching requires teachers to inspire students, mainly to guide students in the mode of thinking and methods of mathematical concepts in a correct understanding. What teachers need to do is to encourage students to self-doubt, inspiring students to identify problems and challenges issues. Teachers should actively to creat the situation of questioning so that students can initiative to explore, rather than the passive acceptance, and only under this condintions that will play a good action on students'personality and create a good boost.During the period of conceptual mathematics teaching, teachers should stick to the principle of issue-driven, persuasive, layered tips, penetration of methord and reflection consideration, and show the discovery process of mathematical concepts, revealing the nature of mathematical concepts, exposing the involved experice of students'researching the mathematical concepts, Constructing the links and diagram of mathematical concepts to realize the inspiration and guidance of the thought process of the students in exploring the mathematical concepts, leading the students to retake the math dicovery path, experiencing the important process from involving in question thinking and actively discussion to finding out the nature of mathematical concept.Through researching the strtegies of high school mathematics concept teaching, it finally obtained the following conclusions.(1) The propose of training high school students on the mathematical concepts and teaching strategies for in-depth understanding are properly and effectively.(2) The level of students understanding of mathematical concepts can significantly increase the improvement of student math achievement. Meanwhile, when cultivating and training students'thinking of high school mathematics concept, teachers should pay attention to the following questions:<1> Since the reseach of high school mathematical concepts teaching is a long and gradual process, the guidance and training of students is not suggested to be anxious.<2> The timely feedback is necessary.<3> Guiding students to focus on the regulation of non-intellectual factors.<4> Emphasizing on improving student's cognitive ability and thinking skills.In short, focusing on the reseach of high school mathematics teaching strategies when teaching the concept will show a very important significance to the improvement of students'understanding and ability to grasp mathematical concepts.
