1、1Improve the efficiency of experimental review on the optimization of physics experiment teachingThe main content of physics teaching is to do a good job teaching the concepts and laws, and the teaching of physics concepts and laws must be cited experiments for exploration. Because the experiment is
2、 an important physics research methods and tools, is also an important part of physics teaching. Interesting experiment can stimulate the interest of students to study physics, the intuitive nature of the experiment can enhance students physical concepts and laws of the memory, orientation of the ex
3、periment can inspire students to take the initiative thinking, the credibility of the experimental students concepts and laws a correct understanding. A projection technology, enhanced the effect of the demonstration experiment Demonstration experiment, a combination of physics teaching in theory an
4、d practice is an important means to enhance students interest in learning, inspire students to positive thinking, is the starting point to understanding the laws of things, the 2teaching of physics experiments an important part of students by observing the demonstration, thinking summarize, in order
5、 to identify regularities and draw the right conclusion. However, some experimental observations demonstrates the target high and subtle phenomenon, and due to constraints, teachers can only speak on the table demonstrate back row students see clearly the experimental phenomenon, which increases the
6、 students difficulty in understanding the process of a direct impact on the effectiveness of teaching. projector will demonstrate the phenomenon of amplification, so that it clearly displayed on the screen. both for students observing and thinking, but also shorten the observation time, thereby enha
7、ncing the effect of the demonstration experiment. For example, in the determination of the density of this experiment, the purpose of the experiment is to practice scales, learning to use the graduated cylinder, and learn to use a balance and graduated cylinder to measure the density of matter in th
8、is experiment, students are first learning the use of graduated cylinder to measure liquid volume and measurement the size of a small piece of 3metal. before doing the experiment, teachers should be teaching students how to use the graduated cylinder, the proper reading. smaller scale graduated cyli
9、nder, teacher demonstrates explain, most of the students is not clear when the use of projection technology. scale amplification, it is easy to see students. Experimental video, to enhance students experimental skills The key to the students to experiment with the first viewing period of the experim
10、ent made by operating video, look at the experimental operating the video at the same time, the teachers to use slow motion, pause, look back at the other methods, make it clear to students the experimental problems that need attention and the experiment was a success is what. visual image to enligh
11、ten students to do this experiment pointed out that a correct the method of operation so that the inevitable can effectively stimulate the students experiments a positive nature, in order to enable students in a relaxed and happy teaching and learning environment carry out the correct operation, obs
12、ervation, reflection and exploration. 4For example, the “balance measured mass of the object of this experiment, students for the first time the actual operating balance due to the reported experiments, listed in the” Note “more, more steps to adjust the balance, students often can not start right b
13、alance or simply not dared to touch it. to face this before now on this section of the experimental course, I first put it again video, so that students carefully watched, and timely prompt attention issues and methods of operation in the readings, close-up of the scale freeze, so that students lear
14、n the correct reading, the teacher prompts each cell represents the number of grams of the quality of the measured object is equal to the weight of the total mass plus scale readings, how to clean up after finished experiment equality. students after watching the video a few minutes to go hands-on o
15、peration, it was easy to do it. Experimental video, to improve the efficiency of experimental review Before modern educational technology has not yet entered school teaching activities, the review of the physical experiments, can only rely on the 5explanation of teachers and students reading to reca
16、ll the process of experiment, results and laws, the students it is difficult to see the experiment process and phenomena, because time does not allow one semester experiment in a school year and the entire textbook system to do it again to the students. However, the use of experimental teaching video, but can enable students to watch some physics experiments operating in the ape to the edge of hours, complete process
