The Study Of Cultivating Chemical Practical Thinking In Junior High School Students

A new round of curriculum reform emphasizes students carry on efficient conversion applications at the basis of understanding the knowledge.The chemistry curriculum standard explicitly pointed out it Should be begin of the experience of students and is about to experience the reality of social life,and helping students understand chemistry and the close relationship of human life,paying attention to the human face of chemically related social problems,cultivating the students' sense of social responsibility,participation and decision-making ability.It shows that chemistry teaching penetration STSE education in the middle school,cultivating students' chemistry practical thinking,improving students' ability to use chemical knowledge to solve the problem of daily life related to chemical,which is of great significance.On the basis of this topic in the literature,with the sternberg ternary theory as the theoretical guidance,the class 5 grade 3 of students in experimental middle school as the research object,combined with the actual,designing the questionnaire and investigation,also analysis of the main factors affecting the development of students' chemistry practical thinking;Putting forward the teaching approach;supplemented with content and problems of chemical for Grade Seven and STSE education;In the form of new courses,experiment,practical activity presents four sets of teaching design;also choose two comparable classes in experimental middle school to conduct the practice research,the class of 220 as the experimental,220 as comparative classes,Design scale test before and after the test,performance evaluation and practice;analysis data and draw conclusions finally.In the study of teaching practice in one semester,the chemistry practical thinking of students has strengthenned,the students' ability of practice,use and implementation has improved,the ability of use chemical knowledge to solve everyday problems about chemical has enhanced.Overall,the development of the students of chemistry practical thinking also has the very big promotion space.
