The Practice Research Of The Problem Solving Strategy About The High School Chemical Industry Process Subjects Based On Analogy Teaching

With the new curriculum reform in high school in-depth,The college entranceexamination chemistry is more and more combined with the reality of eachproduction and living.The college entrance examination chemistry II volume willbe written according to the physical chemical properties of traditional inorganicdiagram inference problem to the production and living of combining thechemical industrial process.It increases on the trend of the percentage involume II.For students, the chemical industrial process problem of solutions hasalways been a difficulty. Because it can test all kinds of knowledge, even testthe ability to obtain information and the processing capacity. So studentsgenerally felt difficulty 、 guilty, they always did not know how to start.Thisseriously influenced the answer rate and quality.In fact, chemical industrial process of problem solving is similar to Englishreading comprehension. Also is to give information to read, to guess, to infer. Soif the teachers can know the problem-solving strategies about English readingcomprehensions, and can apply them to industrial process problem of highschool chemistry problem solving, it will largely reduce the studens’ s fear andimprove the student’s answer rate and corrct rate.Through the literature, this study summarizes problem-solving strategies inEnglish reading comprehension were: extensive reading(skimming), intensivereading(to read), context of speculation, and inference. Researcher Applied thesestrategies analogy to high school chemistry industrial process in the problemsolving, then carried on the teaching experiment and interviews, and analyzedthe results,came to conclusion.Through this research, the flowing conclusions were drawn : the qualitativeresearch conclusion was that students felt a certain routine to solve the problems,they didn’t feel afraid, the students enhanced the confidence of the chemicalindustrial process problem solution; the Quantitative research conclusionsobtained that this reaserch had significant effect on improving students’ sachievement.The researchers puts forward the suggestions combining the research resultsand experiences : interdisciplinary problem-solving strategies of variousdisciplines can learn from each other; On the college entrance examinationchemistry examination paper, in addition to the chemical industrial processproblems presents in the form of flow charts, organic chemical synthesis problemalso appears in the form of a process, a comprehensive experiment topic oftenalso takes the form of process, the topic of these categories can use similarproblem-solving strategies. At the same time researcher points out the shortageof this research: The time of this practice research was shorter, the score of themore difficult chemical industrial process problem coultn’t achieve the idealeffect; The problem solving strategy remains to be improved; There weredifferences between the experimental group and control group on study externalfactors. the problem needing to further improve: the evaluations of this researchon teaching practice of analogy also need to improve.
