A Research On The Teaching Connection Of Exploring Experiment In Chemistry Teaching Of Junior And Senior Middle School

The teaching connection of chemistry teaching in junior and senior middle school has always been paid great attention in the chemistry teaching of middle school. The teaching material of chemistry in middle school has changed greatly in the process of innovation of new teaching. The standard of junior and senior middle school chemistry teaching, especially the standard of experiment, intensifies the exploring experiment in teaching. The new teaching material of chemistry has focused on the design of the content and learning requirements of exploring experiment in junior and senior middle school as a whole. However, it is quite difficult for a graduate of junior middle school to adjust himself to the learning requirements of chemistry exploring experiment in senior middle school, and it takes time for him to do so. As a result, the problem of the teaching connection and transition in the chemistry exploring experiment of junior and senior middle school come into existence.The research on the chemistry exploring experiment of junior and senior middle school is beneficial to stable transition of the initial teaching of chemistry to the basic education of it. After analyzed the related research on this aspect in China, the author of this paper thinks that although a great deal of papers on the middle school chemistry exploring experiment have appeared after the innovation of new teaching, few of them focused on the systematic research of the three aspects in the student-oriented exploring experiments of middle school emphasized in the new teaching, i.e.,"knowledge and skill","process and method"and"attitude and value", still less on that of the teaching connection of chemistry exploring experiment in middle school. This paper has connected the teaching standard of chemistry in junior and senior middle school especially that of the experiment with the related exploring experiments in the experiment teaching material in order to solve the possible problems existing in the connection process of the teaching requirement and experiment content. As for the three aspects existing in the students and teachers of junior and senior middle school in their chemistry exploring experiment, after the basic research, the author connects the humanism development theories involving in the new teaching and the learning theories of structuralism, and proposes some connected strategies in the exploring experiment teaching of junior and senior middle school in order to harmonize the three aspects.It requires a jointed effort of schools, teachers and students in order to successfully connect the exploring experiment in junior and senior middle school. In such process, the prerequisite is the change of education concept and emphasis of the awareness of connection, the base is paying attention to the initial education of chemistry, the foundation is focusing of the connection in the content of exploring experiment in teaching material, the key point is intensifying the exploring of the connection of teaching method in experiment, the importance is intensifying the directing of the connection in the process and method of experiment, and the guarantee is the inspiration of students'affection. The teaching of exploring experiment must base on the teaching standard and teaching material, intensify the connection of the learned and unlearned experiment knowledge with the experiment skills, and connect students'experiment knowledge with their experiment skills. At the same time, the teachers should pay attention the characteristics of chemistry, develop the process and method of exploring experiment, improve the students'experimental skill and make efforts in the connection and transition of exploring experiment processes and methods in junior and senior middle school. Chemistry teachers in middle school should also pay attention to the connection of theories and practices, relate chemistry with daily life, science and technology and social producing, note the latest output of science and technology related to chemistry in order to teach students in time. Improving the evaluation method in experiment teaching and paying attention to the formation of students'science attitude and method are also important in their study. Such improvements make students feel the process of the formation of knowledge and the multi-angled learning method, i.e., combing exploration of science, cooperation with others and learning by themselves, through their learning of experiment knowledge and skill. Such process is also helpful in promoting the development of students'attitude and value system, and the connection and transition of exploring experiment teaching in junior and senior middle school in order to help them to achieve the change of initial teaching to basic science education in chemistry and improve their science accomplishment in it.
