| The continuous development of educational technology promote the transformation of conventional education. Nowadays, educational technology represented by multimedia network technology has been widely used in education, in terms of optimizing classroom teaching, it has its unique advantages. Junior high school physics experiment is not only the prerequisite for learning physics well, but also the means to train junior high school students’science literacy and promote the development of thinking. It becomes a problem of how to use multimedia technology to improve the effect of junior high school physics experiment that every physics teacher needs to think about. Based on some related the theories of psychology and information technology,this paper investigate Junior high school teachers’present experiment teaching status by questionnaires and case analysis. Then propose some feasible improvement to remedy the shortcomings and hope that can provide some reference for frontline teachers.This paper contains the contents as follows:(1)By analyze the status of physics experiment teaching and effect of physics experiment teaching assisted by multimedia in two Junior high school in shenzhen and Xi’an,this paper points out some shortcomings in physics experiment teaching and the advantages in applying multimedia in physics experiment teaching in Junior highs schools.(2)Analyze applying multimedia technologies in physics experiment teaching in Junior highs school theoreticallly, summarize some feasible processes of physics experiment teaching in Junior highs school assisted by multimedia.(3)According to the two summarized teaching processes, from the aspect of application select "atmospheric" and "buoyancy" two cases to do instructional design and cases analysis.(4)Analyze and point out some problems that need to be focused on in applying multimedia technologies in physics experiment teaching in Junior high school.This study has got the following conclusions:(1)Currently teaching high school physics experiment where there are insufficient: ①For unintelligible physics experiment,considerable number of students adopt an indifferent attitude towards learning; ②There is a certain contradiction between students strong desire hands and unsafe physics experiments; ③In demonstration experiment teaching, both sides and rear students can’t see experimental phenomena; ④In exploratory experiment teaching, the way that first, teachers tell students do experiment steps in detail, then, let students do experiment themselves, is not good for student’ autonomous exploration and can hamper the development of student’ scientific quality.(2)The advantages of multimedia assisted teaching junior high school physics experiment have:①It’s a good supplement to traditional teaching physics experiment; ②It’s vivid, impressive,students can achieve good learning outcomes;③Enhancing students’ interest in learning.(3)To solve problems above, the author proposes improvement measures are: ①Through multimedia simulate the unintelligible and exiting security risks and not easy to achieve physics experiment; ②The author suggest a viable multimedia presentation process to physics experiment teaching; ③The author suggest a viable multimedia grouping inquiry process to physics experiment teaching.(4)The attentions of multimedia assisted teaching junior high school physics experiment are: ①Not the whole experiment teaching demonstration by the multimedia presentation; ②Multimedia assisted irreplaceable student self-exploration; ③Teachers should focus on improving the ability to take advantage of multimedia technology. |
