Based on books teaching ---- teaching high school

Based on high school mathematics textbooks, teaching ---- teaching experiences of new materials


Creative spirit and practical ability is China's education reform, quality education is one important task, it requires us to persevere in their daily teaching to carefully study materials, and reasonable to create problem scenarios, enhanced mental training, and actively explore the law, to improve teaching methods to optimize the teaching process. The author in high school mathematics teaching in the new textbooks, found that teachers had properly grasp the ability to impart knowledge and increase or decrease the relationship between the use of flexible teaching methods, textbooks, fully functional, it can be more effective, improve classroom results. High school mathematics is one of the characteristics of new materials to create a variety of problem scenarios, the difficulty of teaching, so that close contact with reality math problems. Teaching practice in the textbooks, textbooks, if always grasp the First, emphasis on the concept of reading textbooks, students self-learning ability. Students often lack the habit of reading math textbooks, which in addition to mathematics is difficult to read, but another reason is that many math teachers in lectures, and rarely read books, talk for like, full full blackboard writing, so that students produce dependence, basic knowledge of mathematics textbooks in mathematics carrier, classroom textbooks to guide students to read mathematics, not only can correctly understand the basics of the book, while you can read between the lines from the book richer content mining In addition, you can play using text books, symbols of the normative role, subtle and accurate that students develop and improve the practice of writing skills and self-learning ability. Emphasis on reading math textbooks, teachers guide first, especially in teaching the new class, that should be corrected, open textbooks for students, teachers, textbooks, according to the original word for word, sentence, section by section to read. In reading, students repeatedly careful thought, the book describes the concepts, theorems, definitions of key terms are essential characteristics to carefully taste, a deep understanding of the semantics, not some time to ask: If you replace the other word lines ? Omit certain words right? With a certain word right? Etc.,polo ralph lauren, to read the book points out, difficult and doubtful, read between the lines that contain the content read out from the text to extract mathematical ideas, viewpoints and methods. Mathematics teachers in the classroom reading books, writing on the blackboard not only save unnecessary time and can prevent slip of the tongue, the concept of a clerical error arising from errors, so that students can accurately grasp the textbook knowledge and improve classroom efficiency. To help students in extra-curricular or curricular reading, teachers can also list the study outline, so that students understand the text better and faster, for example, what period of high vector graphic vector graphic coordinates computing section, the author intends to outline the following reading, students read self: plane vector coordinates is done? Starting point at the origin of the vector, the starting point not the origin of the vector, equal vectors, their coordinate system is how to express it? Two vectors parallel, its coordinates that? Reading of texts by the students, to deepen the students understanding of the text, to improve the students learning ability. Second, tapping hidden textbook knowledge, students research capabilities. High school mathematics textbooks in the abstract knowledge points and implied even more prominent than in other disciplines, mathematics knowledge points to pass in order to reveal the thinking and logical reasoning, as students by thinking and reasoning capacity constraints, and the habit of not reading math textbooks, many students of mathematics teaching to read, do not understand. In order to complete secondary school mathematics teaching purposes and tasks of the first teachers should carefully study and become familiar with teaching materials, teaching materials to those embedded in the point of digging out implicit knowledge to help students understand the material and master the material in order to develop students research skills. Example, to determine the function of the parity equation f (-x) = f (x), f (-x) =- f (x) implies a symmetry about the origin domain this premise, and students often ignore this important premise which led to mistakes. Another example is learning series general term formula, it should be noted that (1) not all series can write its general formula; (2) The same series of general formula is not necessarily the only ; (3) only a few can be summed up by former unlimited number of Another example is the definition of the vector parallel to the two zero vectors on the implicit this knowledge is not parallel to the vector points. Implicit knowledge of teaching through the teachers of the excavation, to stimulate the enthusiasm of students to learn mathematics, an increase of students to explore issues, research problems. Third, the analysis of textbook examples, problem-solving abilities of students. Selected new materials are typical examples, are carefully selected, has a representative, and examples play a rather important role in teaching, improve teaching examples, in particular, to engage in textbook example of good analysis of teaching, not only to deepen their understanding of concepts, formulas, theorems of understanding, but also to train students to identify problems and problem-solving ability and abstract thinking ability, etc., can play its unique function, the analysis of examples from three major two aspects:
