1、1About the New Curriculum preliminary computer algorithmHenan Province High School began in 2009 into the new curriculum, compulsory 2 preliminary algorithms, this, do not understand the attitude of some teachers held that the lack of “mathematical flavor”, belong to the contents of the information
2、technology courses but actually close relationship of mathematics and computer professional name in the University called information and computing science from training objectives point of view, the profession requiring a high level of mathematics and computer. either basic or applied, mathematics
3、and computer combination more closely, as mathematics, in addition to the few pure research should be on the computer better, especially in the algorithm. Today, the computer is not only in the form of changing the way we live, but from the depths of thinking changed our understanding of the world,
4、the transformation of the way the world had a profound 2impact on how we think about the problems faced and how to solve the problem shows that the algorithm initial introduction of secondary school mathematics teaching is in line with the countrys education status today and to adapt to the requirem
5、ents of the development of the times if only set in the computer science, it will not be due the popularity and attention, to the Na mathematics textbooks, the situation is different, due to the impact of the college entrance examination baton, teachers and students will give sufficient attention to
6、 the teaching of this chapter. Algorithm in the new curriculum to increase the content, but closely linked to the knowledge of the front and very close ties with the practical problems. Preliminary knowledge of the high school algorithm and function, the number of columns, trigonometry, probability,
7、 the actual problems integration is the Entrance Examination Proposition new bright spot, also a new hot spot. Such questions follow “knowledge network the interchange design questions” proposition principle purposive aim to meet college entrance 3examination, which also highlights the characteristi
8、cs of mathematical disciplines. Since 2007 the first batch of the new curriculum, Shandong Province, first entrance into the new curriculum reform four provinces of Guangdong, Hainan, Ningxia, I focused on examining the four provinces of the four-year college entrance examination questions and refer
9、ence to other provinces in the college entrance examination papers, while in-depth study the entrance examination outline and the new curriculum standards designed to summarize the entrance of the form and characteristics and the prediction algorithm preliminary questions, types of questions and sol
10、utions. Examine the form and characteristics: multiple choice, fill-in the meaning of the main test algorithms, flow chart, the basic algorithm statement, generally have one question for each paper, few questions, and more for the mid-range questions around the inferior race type questions. The Answ
11、er question by allowing students to read the block diagram to solve other problems, such 4problems are often combined with the series title together with a comprehensive, can examine the students ability of knowledge map and sequence knowledge mastery. Proposition trends and forecast: examine the st
12、atement of the basic algorithm. These kinds of questions, the main test of the understanding and application of the basic algorithm statement, the entrance Usually the choice, fill-in-the-blank form, often two kinds of questions: one is the lack of an algorithms key statement supplement, and another
13、 is to write the results after the implementation of an algorithm, the difficulty is not the solution of such problems should master the various statements of the format, according to the requirements of the subject, the use of the appropriate statement design algorithm. examine the functionality of
14、 the block diagram. Often two questions: First, the block diagram is given that the function, pointed out that the block diagram of the output. Such questions to test students 5in reading ability to understand the block diagram. perfect condition or contents of the block diagram. Incomplete block di
15、agram to fill some of the conditions or content, is an important entrance examination examine the algorithm knowledge questions which require students to the basics of a solid, comprehensive analysis capabilities. design flowchart or write a program to solve the problem, the algorithm preliminary qu
16、estions more difficult questions, such questions will generally answer questions as the carrier algorithm knowledge with other backbone intersection at the same time, ask students to understand the algorithm essentially focus on the process of thinking. far this type of exercise rarely appear in the entrance examination questions. to solve practical problems. Kinds of questions related to the actual problem is often more difficult and general
