Cultivation Study Of The High Three Students' Concept Of Conservation In The Chemical Review Lessons

The fundamental purposes of high school chemistry are enhancing all the students'science literacy. What kind of knowledge about the overall development of the people will be greater value? How to make the chemical education in the secondary school has an continuous effection in students development all over their lifetimes? The Prof. Song Xiqi had pointed out:"students can establish basic chemical concept should be the first target of chemical education in high school."The uniform examination outline of new ordinary senior high school chemical course standard on recruitment of students in China's colleges in chemistry, pointed that the chemistry test"On the basis of the test for the further the necessary knowledge, skills and methods, Comprehensive inspection of the chemical scientific literacy."The concept of conservation is the basic concept in whole science of chemistry, also is the most substaintial part of the chemical basic concept.For the above reasons, we raised this subject. The subject's goal is to discuss the value of learning chemical conservation in high school, to structure strategies in cultivating the high three students'concept of conservation in the chemical review lessons, which will provide some reference value for the chemical review.This research is on cultivating the high three students'concept of conservation in the chemical review lessons, its major as following:First, by the review of literature and theoretical research, we confirmed the basic connotation of chemical conservation, and the value, and cleared up the carrier of content of cultivating the conservation by combining the specific content of high school chemistry curriculum.Second, to know students' the forming condition of chemical conservation we consulted other experts'style and content of writing questionnaires, and compared the survey of experimental class and control class. The research data is dealed with statistical software, spss177.0, so to take the preliminary conclusions:the two classes of students'chemistry results is match, their chemistry conservation idea formed as moderate to inferior in quality.Third, according to research data and theoretical analysis, we have proposed some teaching strategies in cultivating the high three students'concept of conservation in the chemical review lessons.Fourth, in order to verify the effectiveness of the teaching strategies, we had a teaching of empirical research of the high three students of conservation in chemistry review by "chemical conservation" subject basing on detail of high school chemistry curriculum. The review of the experimental class reflecting the chemical conservation, compared with control class of the traditional way in reviewing.After the research, by questionnaire survey, combined with interviews of students to find the results. We found that experimental class is superior to the control class in chemical test about chemical knowledge and chemical conservation knowledge. So we made the previous teaching strategies are effective and feasible.Finally, we made a discussion of the questions existing in the research, which will provide the reference value for further research.For limited of the time, the sample and the personal level, there must be some loss in the questionnaire, design of preparing teaching, implementation of the experiment and data analysis. As a result, the conclusions of this study need further examination and completement.
