The Analysis Of Verbal As Coding Data In The Process Of Chemical Problem-Solving In The Net For Senior Students

Since 1960s, the study of thinking strategy in solving problem is one of the important researches in psychology and pedagogy. After 1980s, the research of solving problems focus on the collecting and training of thinking strategy, but it is not easy to see some positive research of combining chemistry study with net study by using the form of oral report at home.Under the net, this research tries to analyze and compare the presentation code of chemistry by using thinking strategy. In the experiment, by inputting the presentation code of chemistry problem solution and carrying on the code statistics of different thinking strategy, the data of testing will be collected and analyzed by means of SPSS 10.0. We can summarize the effective and successful thinking strategy of solving chemical problems. The result showed:1.Differences of 'reasoning' and 'insight learning 'for senior students in solving problems of calculation.2. Differences of 'repeating' and 'mistaken attempt' for senior students in solving problems of organic chemistry.3. The existing differences of 'students setting up problems 'and 'insight learning' in solving experimental problems.4. when senior students solve different chemistry problems, there arenot only obvious differences on code frequency of 'explanation hypothesis' and 'reasoning', The code frequency of 'explanation' and 'hypothesis' is also obvious higher than senior chemistry experiment, frequencies on 'hypothesis' on chemistry calculation is higher than on organic chemistry, and 'reasoning frequency' on organic chemistry is lower than on experiment.According to different types of chemistry problems, senior students can improve their correct and efficient rate on problem solution by adapting different thinking strategy and carrying on special subject training .It can help set up a foundation for the experiment of training the thought strategy in solving chemical problems under the network environment, It can also provide believable proofs for the writing of the materials of Network Training Course in solving problems of thinking strategy for senior students.
