Different Version Of High School Chemistry Textbook Dysplasia Study

Cultivating students'scientific literacy accross the board has reached a consensus in scientific education all around the world.According to some extent investigations, there are some defects in the structure of Chinese students'scientific literacy obviously, espacially lack of innovative capabilities and practical abilities. What's more, it was verified that the teaching of ill-structured problem solving is helpful to enhance students' innovative capabilities and practical abilities, thus improve the scientific literacy. It needs some curricula as carrier for the instruction of ill-structured problem solving, and textbooks embody the curricula content, which are the principal media for teaching and learing. Teachers should be familiar with the ill-structured problems in textbooks before teaching them to a better instruction. Therefore, it is wise to know if there are ill-structured problems in three sets high school chemistry textbooks of the compulsory module in the context of new course, and to explicit where are they and how many ill-structured problems and how they are distributed in every textbook. Further more, the characteristics and defects and improving methods of ill-structured problems in the textbooks will be studied. All these problems has great value and should be answered urgently.The related papers of ill-structured problem were illustrated in this study firstly,then the ill-structured problems in three sets chemistry textbooks of the compulsory module in senior middle school were analyzed and counted. The conclusions are as follows:1.There are some ill-structured problems in three sets chemistry textbooks of the compulsory module in senior middle school, which lies in the columns of textbooks, and the percent of ill-structured problems is different in diverse columns.2. In terms of quantity, the ill-structured problem in the textbook published by pepole education press is the most, shandong technology and science press are less than its, jiangsu education publishing house is the fewest.3.In terms of percentage(the number of ill-structured problems account for the proportion of all the problems in compulsory module), the version of shandong technology and science press is the most, pepole education press is the second, jiangsu education publishing house is the fewest.4. The characteristics of the ill-structured problems in three common version are as following mainly:possess various and open answers or no answer at all, and they are related to everyday experiences.In order to optimize the ill-structured problems and make the instruction of ill-structured problem solving effectively, some suggestions are given hereinafter: 1.Textbooks'authors should design ill-structured problems in all sorts of columns during the key period of knowledge formation and consolidation.2.Teachers should learn and research on ill-structured problems, make great efforts to be the designer of ill-structured problem, the supporter and the guider of ill-structured problem solving.3.Education Administration should increase education investment and provide enough teaching facilities and resources to support the instruction of ill-structured problem.
