On the basis of previous studies, through literature studying, this paper exploredin how to combine learning and teaching materiasl, how to deal with the relationshipbetween students and teachers, so as to ensure the effectiveness of the chemicalpreparation before class,and draw the following conclusions:(1)The previewing task should be arranged according to the teaching content andthe students’ situation;(2)The students as the main body, the teacher as the leadership, to ensure theeffective preparation.Investigating through a combination of questionnaires and interviews tounderstand the basic situation of the region’s high school students preview beforechemistry class, find the main problems, after discussion and analysis, get thefollowing conclusions:(1)the purpose and role of the student’s knowledge of preview before chemistryclass widespread misunderstanding;(2) most students dont’t have the good habit of previewing and the methods ofpreviewing are single;(3)factors leading to random and inefficient status of preview before class areboth from students and teachers.Based on the conclusion of the above studies, the paper puts forward teachingsuggestions to improve the current status in two schools where the survey is made.(1)Teachers should strengthen the theory study, strengthen the preview guide.Guide students to science and chemistry class objective understanding, de termine thetarget, layout preview preview reasonable clear tasks, guiding students to master thereading method, implement supervision and feedback etc.(2) Students should actively respond to the guidance of teachers, master thepreview method, develop a preview habit. Students should be based on the type ofchemical knowledge, choose different preview strategy, at the same time, to regulateand Reflection on the activity of preview.Converting the random, casual preview to to the buffet guiding students to learnand giving the learning autonomy to students, will ignite the enthusiasm of students,improve the learning efficiency and create democratic, equal, harmonious teachingatmosphere.
