The Analysis On Elements Of Thinking Of Chemical Experiment And The Research On Its System Of Textbook

According to recent teaching situation of chemical experiments, we analyses teachers' misapply of the mode and methods of experimental teaching and expatiates contradictions between teachers' teaching and characters of students' thinking. Based on the contents of experiments in textbooks, the effect on the value of experiments which is from the choice and the structure of contents of experiments is put forward. Then main problems and obstacles in problem solving of chemical experiments are found through test. Therefore, the teaching and the contents of chemical experiment can make restricts on the development of students' problem solving in experiments.So the thinking of chemical experiments is chosen as the object of this paper. The main aim of this research is to integrate the thinking of chemical experiment with the system of textbook, and help students develop their thinking of chemical experiment. Then students will improve their ability of problem solving in chemical experiments by doing experiments. Thereby, the value of experimental teaching can be well performed.The thinking of chemical experiment is the core of thinking of the experimental problem solving, and it's also the hardcore of the ability of chemical experiment. It's composed of the purpose, content and material, process and method, outcome, character, monitor and habits of behavior. The building of chemical experiments' contents will provide the way to compile chemical experiment textbooks. Contents of experiments in textbooks can be established by using its mode of process. The further structure of textbooks can be designed with its theoretical strategy and experiential strategy.At last, with the experience that the writer taken part into writing textbook of "experimental chemistry" and the modeling of contents and process of thinking of chemical experiment, we explore the textbook based on the thinking of chemical experiment. The textbook will act on developing the students' thinking of chemical experiment and improving their ability of chemical experiment through the chemical experiment's problem solving.
