High School Chemistry Teacher Sign The Form To Optimize The Coding Strategy

The teaching strategy is one of the key influence aspects about teaching qualities,which can guarantee the teaching goal realization.Some research have indicated that, if we research teaching strategy from information theory angle,we can unify each kind of situation under teaching strategy in the information transmission, accepts, the processing and the feedback process,make the teaching strategy more systematized, realize the education process optimization. But material demonstrate that, at present ,people carry on the research of chemistry teaching strategy from the information theory angle is few. Therefore, the author bases on the high school chemistry teaching, selects information signifying and information form optimization in teacher code which is the important link in education information transmission ,uses methods about questionnaire survey, experimental study, interview, lesson plan analysis and so on, inquires the signifying as well as the form optimization strategy of teacher information coding.The results are as follows:(1)The high school chemistry teachers have already utilized many optimized method about information encoding, not on their initiative, but their information signifying as well as the form optimization tactical level need enhancement.(2)Process that the teachers transform the transmitting course contents to suit the symbolic form which the student receives easily is named the Signifying process of teaching information encoding. The empirical study indicates that, the student gain the information which is verbal symbol as central multi-signal combination way more easily. But the different combination way have the influence to the student on information acquisition deviation, gaining the relates between the concept. The non-written signal combination way's have different influence to medium live students and the female student obviously. Simultaneously, the degree of students like different signal combination way also have the difference, the student most like the writing and the graph combination symbol .(3) According to each kind influence of student chemistry study, Signifying strategy that symbol diversification,verbal symbol as central multi-signal combination way ,hierarchical symbol which is proposed by the author can promote student's chemistry study effectively.(4)The process that maintaining in the transmiting information essence content not be affected, the teacher may further carry on the control and the choice to the information form through each method is named chemistry information form optimization. The empirical study indicate that,the means of"appropriate piecemeal","enhances the form intensity"affect in chemistry teaching obviously,and the affection differently between female sthdents and male sthdents,and the different affection to medium live students and the female students obviously.(5) According to each form optimization method to high school chemistry study influence,the form optimization strategy that"unifiy enhance the form intensity and enhance the hypothesized content intensity""take seriously to use appropriate piecemeal in the concept teaching","reduction disturbance information prominently"which is proposed by the author can enhance the efficiency of student chemistry study.
