Convergence Analysis On Experimental Operates Skill Training For Junior And Senior Chemistry Textbook(People’s Education Press)

Chemistry is a discipline based on experiments and it is originated from experiments and is dependent on experiments. Experiments offer us an important way to learn chemistry, experience chemistry and explore chemistry. By observing, thinking and deducting the experimental phenomena, we get to know the tiny atoms and molecules,to realize four basic reaction types,to understand the nature of acid, base and salt, and also to master the reaction principle about things and so on. Mastering the basic experimental skill, lays down a firm found for students to do various chemical experiments. An adequate and coherent experimental skill training will help students carry out chemistry experiments smoothly.Experiments in the chemistry textbook play a guiding role for teaching. If the textbook attaches importance to the basic experimental skill, teachers will focus attention on students’basic skill training during the experiment. So the textbook compile scientifically relation to learning effect. Therefore, if experiment operational skills training link with each other, it will conduce students understand and accept it. Students’ability formation depends on certain operational rules or operation procedures. To complete an experimental task successfully also depends on the basis of practice; and it will help students improve experiment ability and develop students’ scientific explore skills. But everything has to be built on the success of the experiment operation, based on the experiment operational skills training convergence. It is the guarantee of operating experiment successfully.This thesis, under the guidance of the new curriculum theory, will carry out a systematic analysis for junior and senior high school chemical textbooks. It makes a statistic for the experiment content, experiment illustrations, experiment sheets, experiment operating skills, experimental apparatus, using times and so on. Using the requirements that are suggested for both experiments and basic operational skills in the Standard Curriculum as a criterion, and applying the four stage theory on operation skills,which contains operational direction,operational imitation,operational integration and operational skill,the thesis will make from the following six aspects gradation,consolidation,progression,effective migration,integration a careful analysis about the reasonableness and scientificity in the arrangements of the experimental contents, in order to see whether it is proper for students developing operational skills. By the gradation analysis, finding out the experiment operating skills in the junior chemical are in different levels, shows different requirements from simpleness to complication; by the consolidation analysis, finding out most experiments operating skills in textbook are full exercise, based operating skills strengthen well, but the textbook gives few exercise in some based operation; by progressive analysis, finding out the textbook arrangement regards the exercise logics, correspond to the students physical and mental development, help them to accept more in the exercise; by the effective migration analysis, finding out the similar operating skills exercise in junior textbook are making effective movement for the senior section, promote new experiment skills foundation; by the integration analysis, finding out skilled operating skills is enough for integration application, textbook arrangement is from skills to ability, achieve transition from operating skills to integration thinking, by qualitative to quantitative analysis, finding out qualitative experiment are major compartment in junior chemical textbook, quantitative experiment are major in senior textbook, achieve accurate requirements of "quantity".1wish the analysis above can offer a valuable reference for the practice of teaching,and making textbook serves well for education.
