A Study On The Solving Of Primitive Chemistry Problems Of High School Students

Chemistry plays an important role in human development, servicing the life and production, it has been widely used in life and production. Chemistry teaching is to train students to use chemical knowledge to solve practical problems. To study and solve the problem of high school students in the past, students often have difficulty in solving practical problems, in order to solve this problem, we can refer to the original chemical problems as new teaching materials.The original chemical problems are scientific phenomena and facts which are derived from the nature, social life and production practice,they had never been transformed by human beings,keeping the original state and can reflect scientific concepts, law nature.They have unique role on the cultivation of students’ thinking quality, stimulating learning motivation and training innovative ability.This study analysis the characteristics and educational functions of the original chemical problems through the literature study and theoretical analysis methods.Through the survey and interviews, empirical research, exploration of students to solve the original chemical problems and obstacles factors affecting students to solve the original chemical problems.With the submitted test for students volume analysis,we have found that the high school students have obstacles in the process of solving the original chemical problems, mainly in the following four aspects:high school students have a problem representation disorder solved the original chemical problems, high school students have obstacles of knowledge application solved the original chemical problems, high school students have solved the original chemical problems the quality of senior high school students with obstacles obstacles will solve the original problem of chemistry thinking method. And through the interview factors solved the original chemical problems were analyzed, according to the interviews of the students, comparing with the chemistry exercises,the students think the original chemical problems is difficult, and it mainly effected by the representation ability and knowledge application ability, psychological quality and thinking method. According to the research and empirical analysis of the original chemical problems in chemistry teaching suggestions.To choose the appropriate actual level and the progress of teaching students, classroom teaching in the original chemical problems in gradient questions, reduce the original chemical problems, in addition, gradually infiltrated the original chemical problems in chemical operation,which can help the students learning how to solve the original chemical problems.
