The Research Of The "Preliminary Algorithm" About Teaching And Examination In Senior School Mathematics

In order to conform to the needs of the times,senior school mathematics which is a basic discipline of secondary education,has carried out a series of reforms,for the purpose of achieving better integration of information technology and mathematics curriculum,the country in 2003,has promulgated the "new senior school mathematics curriculum standard",and put the "preliminary algorithm" into senior school mathematics curriculum system.This opens a new chapter in the study of senior school algorithm.The teaching and examination questions about "preliminary algorithm" have been researched in this article,and the main content is the following four areas:1.In order to understand the students' mastery about the knowledge of "preliminary algorithm" and the evaluation of the algorithm question about Henan Province college entrance examination in 2013,this study has used the method of questionnaire.The students who just have attended the national college entrance examination and who will participate in the examination were surveyed.The questionnaires were analyzed with the method of statistics.Here are the following conclusions:(1)The understanding of algorithm knowledge for the students is not comprehensive;(2)The interest of learning algorithm is not positive and the initiative is not enough;(3)The students lacks of the awareness of application in algorithm and the ability to apply the algorithm is not strong;(4)The students most think the problem which is about algorithm in the college entrance examination of Henan Province in 2013 is simple.2.Abiding by the basic idea and requirements about "ordinary senior school mathematics curriculum standards",and combining with the problems about "preliminary algorithm" of the students in the questionnaire,this article has studied the teaching about " preliminary algorithm" in senior school.In order to enhance the students' interest in learning algorithm,the chapter of "preliminary algorithm" in the textbook has been analyzed with the main direction of the history of mathematics and mathematical culture.Combining with my own learning process,it tries to explore teaching strategies to help the students better understand the algorithm knowledge and enhance their awareness of the application of the algorithm.3.Considering the previous studies,it summaries the strategies of examination about algorithm questions.The questions about algorithms knowledge of the college entrance examination mathematical papers in the years of 2011,2012,2013,are analyzed,including the types of questions,relating to the "preliminary algorithm" knowledge,as well as the combination with other senior school mathematics knowledge.And it makes focus analysis on the 2013 College Entrance Examination of provinces and cities entire country about science department of algorithm questions.This will provide a basis for drawing up questions.4.Combining with the theory of selection and establishment about test questions on measurement and evaluation in mathematics education and the evaluation of the algorithm question about Henan Province college entrance examination in 2013 in the questionnaires,it tries to draw up some questions,and in order to provide information and reference to the examination of "algorithm preliminary".In the last,this study gives some advice about teaching and learning of algorithm,and hopes to generate some help in teaching and test about algorithm and also provides some relevant research material of algorithm knowledge for the senior school.
