The Comparative Research On The Content And Implementation Of Algorithm Preliminary In High School Between Different Versions

In the new Mathematics Curriculum Reform of senior school, teaching content and teaching methods had a important change, increasing"Algorithm Preliminary". How to follow the basic idea and specific request of Courses Standards to Reasonable Show the content of"Algorithm Preliminary", and how to effectively evaluate the effect that have shown .All of these have been urgent problem that should been saluted.The papers take three typical version math experiment textbooks of courses standards senior schoo(lthe edition of People's education press , the edition of Jiangsu education press and the edition of Beijing Normal University press) for example. From courses capacity,writing form,material choice,showing style and the joint of information and technology, I analyses the showing features and showing rules to"Algorithm Preliminary"of three typical version ,and find Success and failure.Through studying ,we find :First, from the perspective of course capacity, the three typical versions all written the teaching content according to Courses Standards ,basically show the request of Courses Standards to textbooks . Course capacity are the same generally,but also have some different.Second, from the perspective of writing form, the textbooks content of People's Education Press is more fragmented ; the textbooks content of Beijing Normal University Press is more aggregated ; the textbooks content of Jiangsu education is between them .All the three version textbooks take the writing form of"Spiral Rise", they all have two Clues at the same time. One is Knowledge Point Chain(Scheduling Order of Knowledge Point),the other is logic demonstration Chain(Level of logic demonstration).The differences of the three version show: first, scheduling order of knowledge point is different; second, Level of logic demonstration is different.Third, from the perspective of material choice, all pay attention to Scenario problem in fact ,take the form of activities,game and anecdote , Which the students like ,showing the using of math in life and technology development. Generally speaking, the textbooks material of Beijing Normal University Press is most ,form is diverged. The students like it.Forth, from the perspective of showing style, the three version textbooks all pay attention to the Consistency of knowledge, People's Education Press version and Jiangsu education version show according to the style of knowledge to idea. But Beijing Normal University Press version show according to the style of idea to knowledge.Fifth, from the perspective of the joint of information and technology , Jiangsu education version and Beijing Normal University Press version are better. Jiangsu education version pay attention to Excel in programming , which is easy ; Beijing Normal University Press version pay attention to Learning Algorithm Language and the students Operation to computer ; People's Education Press version is bad in this regard .The result of the investigation indicated that it is successful to involve contents of Algorithm Preliminary in high school mathematic curricula on the whole. Most teachers and students welcome the involvements of Algorithm Preliminary and agree its educating significance; however, there are there problems in practice: First, after study Algorithm Preliminary, students are not understanding it and not to apply it. Second, there are not enough curriculum resources and teaching class for teachers. Third, the evaluation of the conclusions drawn from Algorithm Preliminary is lack of theoretical guidance.Through the analysis ,we knew, the three typical version textbooks according to Courses Standards have a good try on showing the idea of Courses Standards ,and have made contributions to the textbooks reform .But, they need change in some area, the writer have some suggestions as following:The textbook wants the algorithm preliminary sequencing on present the thought that so that ten can display the algorithm preliminary curriculum value effectively.The material choice should be close to the life and community, and need picture and text so that it is colorful and enlightening.The problem context should be true and interesting so that the students are glad to learn and have benefits to help them solute problem in life.The textbooks are different in structure ,but in a textbooks it should be the same from beginning to after.Strengthened the joint of information and technology , we can introduce information technology in text. It should have style and features itself.Simultaneously, In order to effectively improve high school mathematics plausible reasoning, in view of curriculum, evaluating, teachers and so on, I think, first of all, teach plausible reasoning as early as possible, and combined with the other chapters, reasoning infiltration of the application; Second, the expert should combine example, give a specific evaluation method; Third, strengthening teacher training; Finally, the teachers themselves have to do research, and think more about how to teach such content. We hope that these proposals can provide reference for the implement of the new curriculums in our country, as well as make a bit contribution to improve the new curriculum.The papers will have some revelation effect on the Mathematics Curriculum Reform and the construction of the textbook.
