Exploration Of Optimizing Instruction Design In Chemistry Experiment

The experiment is the foundation of chemistry and its importance is obvious. Teachers tend to impart the knowledge but neglect the experimental part,in the current chemistry teaching for senior middle school, Under the new curriculum standard, this research emphatically discusses the chemistry experiment class optimized design By studying the present situation of the middle school chemistry experiment teaching and anglicizing the problems, as well as researching the chemistry experiment questions in recent NMET tests, I want to optimize chemistry experiment teaching and make the class teaching free. In this way, the students can master the knowledge easily.The degree paper can be divided into four parts.The author has analyzed the present situation and the prospects of NMET tests system. The essay can be summarized in five parts: NMET tests system is relatively fair; NMET tests system needs to reform, then it can adapt to the society better; NMET tests is not the causes of examination-oriented education. It has the same goal of Quality-oriented Education; NMET tests itself is consummating unceasingly. The proposition of NMET tests presents the new characteristic; the proposition of chemistry NMET tests pays great attention to the ability and the diathesis examination. The author pointed out that, chemistry NMET tests set high goals for scientific and cultural qualities today. Examinee's innovation spirit, chemistry thought ability, the experimental ability and the application ability will be the inspection key point, chemistry experiments as the important constituent of chemistry, may enhance middle-school student's scientific quality.The second part conducts the research in the proposition of NMET tests. The proportion of experimental chemistry questions is enlarging. It has highlighted the tendency that chemistry subject attach importance to the ability and the quality. The author sorts the questions into operational, principal, information migratory and the experimental design questions. Each kind of questions has carried on the examination from the different ways. According to the feature of the experiment questions, the elementary knowledge of experiment is remembering no longer, its examination depth is enlarging; Practice ability of relating the actual is gradually becoming the key point; Studying the research of inquiry learning has manifested encouragement of scientific research ability; The design experiment has restrains the positive guidance function to the excessive assignments tactic. Through the above analysis, we can sort chemistry experiment ability into: the ability of operating, the ability of discovering, choosing subjects, and the ability of designing and estimating the experiment plan, the ability of observing and recording the experiment, the ability of thinking and self-learning.The third part is the investigation. In order to know the situation of chemistry experiment teaching in ordinary high school, the author has carried on the survey to the students of grade 3 from ten ordinary high schools. We have analyzed the research in these factors: demonstrating experiment, students? experiment, the situation of experiment grouping, tendentiousness of the way, the situation of the test report, the assessment of experiment. On the whole, the situation of demonstrating experiment and the students? experiment is good. But the development rate of town school is lower. The facilities of the students? experiment must increase input. The situation of students? experiment report is not optimistic, it has many problems. The students are inclinable to look other students making experiment and do the experiment from the books. They are unwilling to design the experiment or take part in the extracurricular experiment. The type of experiment instruction is approaching transition from "the confirmation" to "the exploration". The way of experiment evaluation still pays great attention to the written examination and neglect the operation test. In view of the above phenomenon, this document has made analysis and put forward the proposal.The fourth part has studied the basic questions of instruction design, intends to establish the author(?)view of instruction design. It has pointed out the optimized instruction design in chemistry experiment emphasizes that teaching must face all student, take the student as the main body. We have analyzed the investigation item by item. Aiming at actual condition of current chemistry experiment teaching, we have optimized the instruction design of chemistry experiment. The key point which this article discusses is optimized processing of teaching content in chemistry experiment lessons, choosing the proper teaching method, choosing and utilizing the teaching media.The fifth part has summed up and reflected four aspects of the full text. It has drawn the research conclusion, specifically has pointed out the next research question.The entire paper has presented an open research system.
