The Research On The Character Of The Distribution Of The Importance Of The Teaching Contents In Chemistry Classes And The Correlationship With Teaching Time In Senior School

With the reform of the new curriculum fully implemented in our country, not only themajority of the people who works on the teaching theory or the people who works on theteaching management, but also the teachers who work in the senior school, are studying andpracticing the ideas of the new curriculum, new teaching and evaluating methods. With theguidance of the ideas of the new curriculum, all Chemistry teachers are devoting themselvesto develop various teaching methods and strategies to teach in high efficiency in the class andto improve the teaching quality, and they all design the teaching process elaborately in orderto fully establish the three-dimensional objectives of new chemical curriculum. Thus, it isessential for us to participate in the Chemistry class and study in detail. In theory, thebackground of this paper is according to the model of CPUP and corresponding literatures byZheng’s group from Northeast Normal University.In this paper, the evaluatin of the twelve selected samples are trough literature analysis,observation of the classes and statistical analysis, in order to obtain the the character of thedistribution of the importance of the teaching content in Chemistry and the relationship between theteaching time in senior school. The primary conclusions are as follows:1. Teachers in the twelve selected samples all used more than20elemental contents.2. The distribution of the elemental contents of different importance in quality classes isequal to normal classes, and the teachers can master the teaching contents reasonably.The assignment of the teaching contents in the quality classes is similar to the normalclasses.3. With the increase in the importance of the teaching contents, the teaching time alsoprolonged in the quality classes. Nevertheless, the teaching time from long to short innormal classes is D, A, B, C.4. In quality classes, the elemental contents of different CID were establishedalternately, and the distribution of the CID-teaching process presented serrationobviously. It shows that the distribution of the important teaching contents isalternate, variational, and well-organized. Teachers can master the teaching timereasonably, and keep the class in good step.5. Although the elemental contents of different CID were also established alternately inthe normal classes, it just appeared in the first thirty minutes in the class. After that,teachers paid more attention to the exercises, so that a relief station appeared. As aresult, the percentage of the teaching time and the frequency of the elementalcontents of class D are high in the normal classes. 6. The evaluation of quality classes and normal classes through P-P showed normaldistribution.7. In quality classes, the coefficients of the importance of the teaching contents and thecorresponding teaching time are r=0.622and p=0.000, respectively. It suggests thatthere is a good relationship between the mportance of the teaching contents and thecorresponding teaching time. It means that the more importance of the teachingcontents, the longer is the corresponding teaching time.8. There is no relationship between the importance of the teaching contents and thecorresponding teaching time in normal classes.I wish that this paper can provide a new approach to calculate and design their teachingprocess.
