Concerned about the changes in solid geometry
traditional materials and new curriculum standards in dealing with three-dimensional geometry there is a clear difference, so how the pro forma three-dimensional geometry of the most controversial, most confused, and these are reflected in the focus point, line, surface location relations. First, we should pay attention to differences between the old and new materials:
(1) the traditional teaching materials focused on spatial point, line, surface relations and axioms and theorems related to the corresponding proof of reasoning.
new curriculum standards will be above to dilute the requirements of the capacity to reasoning and proof, the simple combination of demonstration and numerical calculation is to examine together the key.
(2) liberal arts mathematics learning in the compulsory two Cartesian coordinates in space, which can be considered to be more inclined to three-dimensional geometry of the numerical calculation and is the algebraic (a spatial Cartesian coordinate system) calculated some geometric volume (point to point distance).
in 2011 pro forma in the three-dimensional geometry should note the following:
① space point line and surface to grasp the scale of location relationship, focusing on the basic line in the parallel and vertical on the surface should not be learning vector approach.
② three-dimensional geometry is also innovative, Guangdong in 2007 to combine three-dimensional geometry and function, 2008 years reflected in the three-dimensional geometry, trigonometric functions in the role of numerical operations are good try.
when reviewing Several Relations
1.
base and improve the relationship between mathematics college entrance review, the appropriate to reduce the starting point to meet your level based. return to basics, to find his own shortcomings and to develop further training programs. Shiyibuque point of knowledge is also a way to improve. advocate for Each time the error will be registered training, often to remind myself. return when reviewing materials to control textbook directory (data directory) memories and sort of knowledge, should be formed in his mind clear of knowledge. on the basic methods and techniques can not recall out, to make up time. to focus on the grasp of knowledge and problem-solving examples include methods to select the subject of a number of targeted intensive training.
2. a comprehensive review of the relationship with key
in Review comprehensive review, based on the characteristics of their own to do more for key exercises. The first is their weakness, weakness, followed by the main entrance of the content, the best review of the establishment of special topics, can be made in the issues paper together to review and collated from the sum and summary of the basic kinds of questions and methods. backbone are: function, series, trigonometry, inequalities, solid geometry, analytic geometry and the new additions.
3. to do the number of questions and quality in the final stages of the relationship
some of the topics to be selected to do, the amount is not more entitled to be typical, in conjunction with our previous analysis to select the topic should be targeted. but also for their own weaknesses, not do tricky question, strange title. problem is not necessarily a good question, simple questions may also be a classic.
common in mathematics college entrance test focuses on the use of conventional methods, focusing on continuity through law, appropriate dilution techniques. is not to say do not skills shown with the column sum of the number of tricky ways mm finale math contest questions often some connection.
4.
relationship between practice and reflection in the finish or the teacher to explain a practice completed a subject, the reflection is particularly important. must not be too much for the pursuit of neglected after the reflection. done after the subject, we should reflect on whether the skilled knowledge extraction: This question involves what important knowledge? subject of special where? Second, we must reflect on whether the method familiar: use what method of thought, problem-solving ideas how to find it? Where is the key to solving problems? it met a similar topic? have confidence in the future to meet this kind of problem to solve? Third, we must reflect on the weakness: why does not answer that? What are their mistakes? Why is this wrong?, etc. other.
In addition, not to problem solving and problem-solving, to learn to learn by analogy, not only do, but even simpler solution. driven by a multi-topic issues, the problem from a different perspective, does not meet the existing method, from another point of view, this approach is particularly useful in solving problems.
5. problems and mid-range between the subject title is not afraid to do not
entrance, afraid to do wrong. In fact, you will do as long as their Title basically doing the right thing, the biggest reduction in the errors to have been successful, the time to review the accuracy and speed of problem solving to work on.
6. to see problems with the pencil, the intervals between
have done their own time recently to digest and organize the subject, which is the process from quantitative to qualitative change, to sort out different categories. But we can not just questions and answers, which is particularly important. Remember, math is to look not and must be the combination of thinking and you begin, we can maintain a good competitive state.
seven, attitude adjustment, master math college entrance examination skills
mathematical knowledge is not only a contest, but also the quality of candidates and examination techniques of psychological Competition . the examination process should be relaxed, Ting Dezhu. spirit to focus, attitude to peace, to learn to self-suggestion. Now the college entrance examination is also a test of the quality of student's personality, psychological quality good, will be able to achieve good results.
Note entrance is tight, but also the eve of harvest. Thick Pu education in this wish all the college entrance examination in 2011 achieved brilliant results.
