1、1High school chemistry experiment on the teaching and the integration of multimedia teaching techniquesAbstract: chemistry experiment in high school chemistry teaching is the most commonly used means. However, because the conditions necessary for experiments demanding. Therefore, in the traditional
2、teaching, the role of experiment has not been fully reflected in the experimental teaching using multimedia, you can overcome this limitation. Improve the timeliness of the experiment to ensure the safety of the demonstration experiment. Experimental operation to strengthen the normative students, f
3、or students to create the conditions for the experimental design. Enriching the students experimental knowledge. To maximize the role of the experiment. Paper Keywords: high school chemistry experiment, multi-media teaching technology In teaching. We have implemented multi-media tools generally incl
4、ude: computer technology, network technology, projectors, cameras, etc., which need to be flexible to use in teaching. Vary according to local conditions. Below, the author discusses 2here about several aspects of multimedia in teaching chemistry experiment First, in experiments using projection tec
5、hnology Experiments in chemistry teaching. Its purpose is to enable students to understand the material through the experimental process of change. Perceptual knowledge through experiments, which go up in rational thinking and questioning. A conclusion, and to improve their level of awareness and ca
6、pabilities. And. Experiments to some extent, can increase student interest in learning, improve student learning motivation and participation. And the fact that its experimental, scientific students convinced. Is to train students to observe, innovation an important way. So. Experimental demonstrati
7、on to really play a role. Can not play without the show, so that experimental demonstration experiment into speak. Experimental phenomena observed experimental phenomena into speaking. In order to improve the visibility of the demonstration experiment. Methods commonly used to enlarge the traditiona
8、l experimental apparatus, raising the experimental device, increasing the amount of experimental drugs to repeatedly show such results. However, 3amplification of laboratory instruments is limited. The results again show a waste of time. And some instantaneous phenomenon is asked in the experiment c
9、an not be seen arising. That affect teaching. And projection technology used in the experiment, can greatly improve the situation, to overcome the defects and improve the demonstration effect of projection technology is the main function of the experimental process and the phenomenon of amplificatio
10、n. To overcome the traditional experimental visibility of small defects. Enable all students to clearly observe the experimental process. In particular, some subtle and not easily observed phenomena. Projection technology to improve the scientific experiments. Enhance student learning motivation and
11、 involvement. To develop students ability to provide the conditions observed. Second, the chemistry experiment in how to use the camera, video technology In teaching. Sometimes the process involves some changes in the longer experiments, and in the course of the experiment will produce some marginal
12、 phenomenon which for students is a test of patience and attention to students in the experiment, 4however to always want to maintain a high level Note that it is not easy. And classroom time is limited. Teachers should let students in the limited time access to information as much as possible. Ther
13、e should be selective observation of the students time to give guidance. Observations to ensure that students learn the knowledge of the value. So. Using camera, editing techniques, processing of the whole process of experiment. Not only to provide students with the whole process of experiment. But
14、also highlight the important experimental phenomenon. The same time without losing the authenticity of the experiment. Some experiments with a certain degree of risk. For example there will be more intense reaction or produce harmful substances such as gas and so on. Therefore not suitable for exper

And to achieve the objective of teaching experiments through experimental video technology can also be caused by wrong operation in the true representation of the hazards. Aroused the attention of students. Experim
16、ent to help students master the correct steps and skills that teaching can enable students to correctly grasp the operating rules 5and correct understanding of experimental apparatus. The success of the experiment play a role. Functional effects of video technology. Full advantage of this effect. Can demonstrate the authenticity of the experiment, such as: high-speed or slow the experimental procedure can be put as the fast, s
