Based On Light Signal Of Chemical Experiment Design And Teaching Research

If practice is the foundation of the people to know the world, the experiment may be the basis for the students to understand chemistry. Chemical experiment is an important part of chemical discipline, it plays an important role in teacher’s teaching and students’learning, so the research of the chemical experiment teaching is of great significance.This article compared through two light color change experiment, flame color reaction in middle school and fluorescent probe experiment in university. After comprehensive understanding the present situation of middle school’s experiment teaching and university’s and summarizing by the questionnaire survey, we gained the following conclusions:Experiment teaching between middle school and college needs a further connection, except increasing the experimental skills, we should also cultivate the students" thinking habit and scientific literacy, which makes students adapt the university experimental teaching more quickly.Exploratory experiment makes students learn autonomous and manage themselves, this is beneficial for students adapt college learning environment more esaily.Experimental teaching fits the law of human memory, the changes of the experimental phenomenon easily attract students curiously, which will cause the students’interest in learning and make some underachievers regain their learning interest and confidence. So the development of the experimental teaching helps to eliminate the polarization of the class, then all students can get consistent advance.Therefore, experimental teaching has a new meaning. Teachers need to pay attention to carry out exploratory experiment or self-designed experiment, to exam students’ skills in autonomous study and self management. At the same time, they should also care about underachievers and their progress in the experiment to eliminate polarization.
