Application Of Knowledge Network Diagram In Organic Chemistry Examination Before College Entrance Examination And Its Review Strate

The college entrance examination is the most important selective examination in our country.The college entrance examination,as a national exam,many students,especially impoverished students to the university entrance exam as change life,change the fate of the best choice,the college entrance examination in the society the importance of also do not have other recruitment exam.More than half of the hundreds of millions of students who attend the exam each year have to refer to chemistry,and organic chemistry is the main component of the chemistry of the college entrance examination.How to study,what is the focus of attention,the author of the college entrance examination in 2013-2017 by Richard heald paper chemical volume(in schedule 1,schedule(2)organic chemistry test part analyzed the topic analysis,knowledge points,found with multiple choice,organic chemistry,organic chemistry experiment,organic synthesis and infer the examination,inspection every year,a little change of knowledge point of attention to the student ability and the examination of ideas.For students in organic chemistry review the problems and difficulties,the questionnaire survey to find the main problem is: the lack of learning organic chemistry learning,thinking ability is difficult to find the learning rule,types and properties of organic matter into more complex difficulty,etc.Review time tight task of the university entrance exam,in limited time to achieve maximum effect of review,is fighting in the first-line teachers students concerns,choosing the appropriate review strategies can have twice the result with half the effort.Based on the previous analysis,the author summarizes several review strategies of organic chemistry and selects the review strategy of knowledge network diagram.Knowledge network chart review strategy was applied to the three organic chemistry review,building organic chemistry knowledge network diagram from various angles and applied to the practice teaching,after a period of time to review from the level of student achievement and students accept knowledge network chart review strategies for testing.Results: after reviewing method of organic chemistry knowledge network diagram,students of organic chemistry than with other traditional way to review the class,students of organic chemistry review policy acceptance is higher.The research methods of this paper mainly include literature reading method,statistical analysis method,questionnaire survey method,practice experiment control method and written test detection method.
