A Study On The Practice Of Chemistry Experiment Skills Evaluation For Senior Middle School Students

Classroom is the main position of chemistry teaching, classroom teaching is the student to obtain chemical knowledge, development capacity, improve the consciousness of the main channel, and chemistry classroom teaching chemistry experiment is one of the important means. The chemical experiment plays an important role in the chemistry teaching. Through classroom observations and interviews, the writer can see now the status quo of the chemical experiment teaching of high school chemistry teacher and the present situation of the students experiment skill training.Chemistry is a based on the experiment of natural science, the experiment is the base of chemistry learning, and that subliming the theory of chemistry learning. With the deepening of curriculum reform, chemical pay more attention to the development of students, to return to the life world of students. Chemical experiment is particularly important.This thesis mainly adopts the literature analysis, statistical analysis, interview method, research methods, such as the status quo of the cultivation of students’ chemical experiment skills and to investigate. From shenyang, liaoning province a key senior high school grade’s teachers and students as the research object, undertake to the student classroom observation, interviews of teachers, and supplemented by statistical analysis of observation scale method, in order to more fully understand the current situation of middle school students’ chemistry experimental skills. Will look at scale is applied into the teaching of chemical experiment, and the current situation of chemical experiment teaching of middle school students’ experimental skills before, and the conclusion.In the practice teaching and teaching observation, through theoretical analysis, practical teaching analysis, prove that using the method of "observing scale" indeed chemical experiment can help students improve the classroom skills to master the situation.The author hopes that this paper can the study of secondary school chemical experiment skill training and evaluation play a positive role, to cultivate the students’ experimental skills and effective evaluation of students’ experimental skills to provide the reference.
