The Analysis And Research Of CEE Chemistry

As the bridge of connecting elementary education and higher education, the university entrance exam is at the highest level of concern in exams of our country. Its content and mode of every subtle changes will affect the school teaching and the examination review of senior high school. Since the beginning of comprehensive chemical examination in 2001, the exam score in the chemical examination dropped to 108 points from 150 points. However, such change gave us higher request in the review of the entrance chemical exam. Outstanding ability as well as important basic knowledge should be focused on in the review. Therefore, based on the college entrance examination in chemical test as the research object, the thesis tries to get the knowledge which are highly concerned(hot spots) in the college entrance examination in recent years, thus being a guidance for the review of chemistry for the college entrance examination.Based on the theory of multiple intelligences, education measure theory, teaching target classification theory as the guide, comparative research and statistical method of research method, from the Angle of chemistry and statistics, the thesis gives a systematical analysis to the chemistry tests from 2004 to 2008(national college entrance examination test II).In view of the research from the angle of the subject, this paper mainly focuses on two aspects---the distribution of topic sections knowledge and the distribution of the score of each section. Combining the analysis of 2008â…¡national college entrance examination test (chemical analysis of the specific volume), we can draw the following conclusions: 1 the stable test structure and scale, 2 questions based on regression, especially the main knowledge, 3 exams in calculating the difficulty and capacity requirements reduced, 4 basic questions reflect "change" and "new" trend.In view of the research from the angle of statistical analysis, the thesis mainly analysed the frequency distribution trend and classified the elementary knowledge from the system of double-base. The characteristics of chemical examination in recent years are as follows: 1 elementary knowledge and the test of basic skills are mainly focused, especially the main knowledge and important knowledge. 2 the increasing of the comprehensive knowledge of chemistry degree. 3 test focuses on chemical language. 4 the organic synthesis problem of main functional properties of prominence 5 Chemical experiment topic mainly examines the comprehensive capability. 6 chemical computation questions distributed decentralization.In further examination on the depth of the exam comprehensive science chemical analysis, the "hot spots" in the examination are just the key points, and they also represent the development direction of the exam. College entrance examination questions reflect the appropriate difficulty, degree of differentiate, and the efficiency of validity. So students of different abilities can complete different levels of papers. Besides, the study content of different test scores are easily to be distinguished. The research will undoubtedly have positive significance for high school chemistry teaching and the review of chemistry for the college entrance examination.
