The Textbook Analysis And Teaching Status Quo Of The Introduction Of High School Mathematics Concepts

The concept introduction is using a method and method of teaching to introduce concept ,which is intelligible for teaching object .Concept introduction plays a vital role in the entire concept of teaching .This study was conducted using literature analysis, case analysis, text analysis, and questionnaire analysis.Through the literature analysis method, the research status of the concept introduction method is summarized and sorted out, and the concept introduction method is used to classify.On the basis of this, based on the high school mathematics compulsory teaching materials, through the text analysis method, from different knowledge dimensions to study the concept of introduction in the distribution of teaching materials,Come to the following conclusion: (1) Su secondary high school mathematics teaching materials is diversity in the setting of concept introduction, The most new concepts are introduced through the actual examples ,the kind or the model,which is accounting for 35.71%; Followed by the creation of application scenarios and the introduction of new concepts on the basis of the original concept, accounting for 29.46% and 18.75% respectively; And the introduction of new activities from the activities of life or the introduction of mathematics and the inherent needs of mathematics are few, accounting for only 9.82% and 6.25%;(2) different knowledge dimensions are suitable for the different way of concept introduction.The method introduced from the kind is best suited for "geometry and graphics", the original concept of the introduction of the most suitable "number and algebra", The introduction of the most suitable "probability and statistics", the introduction of the law in the "number and algebra" and "probability and statistics" are widely used.Through the questionnaire survey of some high school mathematics teachers, the following conclusions are drawn: (1) Most teachers have been able to recognize the importance of concept introduction to conceptual teaching, but the implementation varies from person to person; (2)Every method has its advantages, but the degree of acceptance is different, The teachers' choice of the way of concept introduction and the style of writing materials are also different; (3) Curriculum standards and teachers both think the most important purpose of concept introduction is to deepen the understanding of the concept of mathematics, the difference is that the most teachers believe that the concept introduction without the need to adhere to whether the concept of essential features.Through the analysis of the specific case, the concept of the four teachers introduced the concept introduction of the three principles: enthusiasm, inspiration and the recent development of the principle of the region.
