Survey And Strategy Research On The Difficult Point Of Chemical Reaction Principle

"Chemical reaction principle" is quite important to us when studying chemistry subject.After the new curriculum reform,high school stage of chemistry reaction principle is concentrated layout in elective four of chemical reaction principle module,which is an optional course including four aspects of knowledge,such as chemical reactions and energy,chemical reaction rate and equilibrium,ion balance in the solution,and electrochemical basis.The module is mainly oriented to the students of studying in science and engineering specialty in the future or interesting in the chemical reaction principle knowledge.Through the study,students will obtain the future development of the necessary chemistry knowledge,skills and methods.Students can also learn about the chemical reaction principle of application in production,life and scientific research.Over the years,in the college entrance examination chemistry exam outline on the principle of "chemical reaction principle" the examination scope has a clearly defined.Many provinces make chemical reaction principle module as knowledge of high school science students must learn and the university entrance exam must test.Therefore,the module is elective,but it's very importent to science and engineering students.There is a big hurdle for students in learning chemical reaction principle,because the knowledge is complex,interrelated and metaphysical.Many teachers impose themselves that thought already teach clearly,students still do wrong again and again.Many students feel puzzled for this part,and think that chemistry is more difficult than the liberal arts such as politics,geography,and history which are easy to get high score.Further,chemistry is more difficult than physical which only need to remember formula,then we can apply.This phenomenon for this part of the practical teaching is a big problem,why students have such idea,and what confused in this part of knowledge?In the form of questionnaire and interview,from different angles survey statistics,respectively questionnaires and interviews stuedents and teachers,analysis the similarities and differences between students and teachers teaching difficulty,and conclude the real difficulty in the teaching process knowledge.All of these survey is to point out design ideas in teaching process for high school chemistry teacher and provide some referencebreak when breaking through the difficult point of the chemical reaction principle knowledge.The breakthrough teaching difficulty,there are several strategies you can refer to:link theoretical knowledge.the cognitive study of curriculum,class set aside time for students to think about?the transition of compulsory and elective content?optimization of elective module teaching order?by analogy to the microscopic world?through the experiment to carry out inquiry-based learning,etc?...
