The Research On The Trend Of Development Of Chemical Experiment In College Entrance Examination From The View Of Problem-Solving

Since the new curriculum reform, the new curriculum aim ,which concerned not only with the training of scientific elite,but with the cultivating of scientific literacy of ordinary citizens,have gain more and more popularity. The problem-solving ,as one of the most important teaching method to develop student's inquiring ability ,begin to domain the chemistry experiment teaching area.We develop student's learning interest and motivation by problem-solving .And let them understand and grasp knowledge through the process of problem-solving activity,which is also an effective way to make them to form good habits of problem consciousness and spirit of innovation.The proposition in the chemistry paper of college entrance examination is under the process of continuously development and readjustment. To examine students'problem-solving ability through chemistry experiment paper, since its emergence, this kind of examination type has become the mainstream type in experiment teaching and examination at present.The research used the document study and textual analysis methods. And through a large number of information inquiry on the content and the developing process of problem-solving, and finally gain the theory and practice of the research,. By analysing the recent sixteen-years'experiment questions in chemistry paper of college entrance examination ,the research gain several aspects of the developing trend in experiment paper. The conclusions of the research are as follows:First, from the view of problem situation in experiment questions:1,The main presentation of problem situation in experiment questions in chemistry paper of college entrance are Algorithmic Problems and Rule-Using Problem.2,The characteristics of the algorithmic problems and rule-using problem have certain complexity, which brings certain difficulty in judging the problem situation by problem-solvers.Second, from the view of problem space in experiment questionsThe main presentation of problem space in experiment questions in chemistry paper of college entrance are Algorithmic Problems and Rule-Using Problem. And the spaces of the algorithmic problems and rule-using problems have certain complexity.Third, from the view of problem objectives in experiment questions1,The main strategies to reach the problem objectives in experiment questions in chemistry paper of college entrance are Algorithmic Problems,Rule-Using Problem and Troubleshooting Problems, while the using of decision and adhocery strategies are less than the former three strategies.2,The strategies of the algorithmic problems and rule-using problems have certain complexity,while the strategy of the troubleshooting Problems has become relatively simple.
