A Teaching Strategy Study About Promting The Shou Heng Thinking Capability Of Chemical Caculation Of Senior High School Students

The educationalists thought:the education main purpose promotes student's intelligence development, raises student's power of thought.Recent years our country new curriculum reform was precisely according to such some advanced theories. Such as in the senior high school chemistry's calculation.Working out the chemical caculation problem is the process of a comprehensive comprehension and the application chemistry notion, priniple, not simple arithmetical operation. Still usually involve some in methods and skill, but these thinking capability of methods and skill is higher request to the student. Passing these make the student learn how to think, improve the student's thinking capability. The association test, the interview and the comparison class teaching experiment's form have been carried on in this paper.The interview with the Shanghai some Key Middle school's six chemistry teachers have been carried on. The two class students of science and the tow class students of arts have carried on the association test.The two class students of science have carried on the principle regular professional training and the comparison teaching experiment.The study conclusion:1 The Shou Heng thinking capability of Gao Er's students regardless the student of science or the student of arts are all lower.2 The high teacher lets the student contact the stoichiometric Shou Heng question to be few, has not made special, system's theory introduction and the training to the conservation thought. Teachers Gao Er generally makes the student get in touch with this kind of subject more, but the method for training is simple, the effect all generally isn't good, when the students meet a similar subject next time,they still can't make out.3 Several kind of editions the teaching materials do not have system's theory introduction or the special training about the stoichiometric parts. 4 The author designed new teaching plan, carry on training to the student, the result displays:it is useful to training the student by displaying the thinking process of Shou Heng question.
