1、1On the teaching of physics experiments in the ground and lazyWith the requirements of quality education, students learn to not only master the basics, more importantly, by learning to lifelong learning ability. Physics is a discipline, such as physics experiments can be used to verify the laws of p
2、hysics, Discrimination of authenticity, so that students acquire perceptual knowledge, develop their operating ability in practice. Appropriate physical experiment teaching, can stimulate students interest in learning, develop good study habits, cultivate observation, hands-on, cooperation, communic
3、ation, communication skills, personality development. be seen, experimental teaching is very important, how to experiment with teaching worthy of our profound thinking. To this end, I personally experimental teaching ground “and” lazy “to talk about some superficial understanding. The ground is prep
4、ared to do more, that is fully prepared to do a demonstration experiment. Before class materials on the requirements of the demonstration experiment, we must try to ensure that the class do a good 2job, natural light such as optical experiments, you need to consider the lighting of the classroom and
5、 laboratory whether the differences, the differences in how to adjust. not to “talk test” approach instead of a demonstration experiment on the blackboard. Ground dug more than the increase, that is not confined to the laboratory to provide the material, multi-tap material in materials and life, acc
6、ording to the teaching requirements and features, student Zizhijiaoju, timely to increase the number of demonstration experiments and student grouping experiments by this experiment. can stimulate students interest. Talk about Newtons First Law of Motion to mobilize students bring their own heavy ob
7、jects (which may be such as books, pencils, paper (or even scrap paper of experience inertia, thus teaching methods, students under the guidance of teachers, and everyone hands. eye movement, brain, tongue, this teaching method instead of the audio-visual teaching, students interest in learning high
8、, strong, durable. Good change in ground research, namely research, 3combined with the school, the students real life, to improve the experiment or change the equipment uses to develop low-cost experiment, the experimental phenomenon is more obvious, more intuitive, easier to operate, the error is s
9、maller. Such as learning interference when two identical 20-cm length of wire angle was tied to the the RBI timer vibration needle about 30 , bend the other end is curved, power, and two curved side of the water at the vibration on the formation of coherent wave sources available stable interference
10、 pattern, easy to observe to understand the abstract concept of interference. Magical Dickens, a number of important laws of physics from the phenomenon of life on the basis of the observed experimental, in turn, these laws and has extensive application in the production and living. Attention to gui
11、ding students practice teaching, learning the combination explain physical phenomena, using knowledge of physics to solve practical problems, so that students feel academic use. Momentum theorem, such as learning, guide students 4to analyze why some people accidentally fell from the second floor, wa
12、s seriously injured falling from the 10th floor was left intact, what to do if they encounter a similar situation. Present demonstration experiments are mostly done by teachers and students into groups for experiments using the traditional “talk and play” mode of teaching. Knowledge-based, teacher “
13、arranged” too much, the student class experiment, experimental exercises and extra-curricular experiment, basically a small production is nominal, the students personality is not the development of easy bruising the feelings of the students of science can not give full play to the unique educational
14、 function of the experimental teaching abroad, experimental or demonstration experiments mostly completed by teachers and students , or side to guide students to the edge experiment. In view of this, I believe that teachers in some experimental teaching should be “lazy”. Experimental operation “lazy
15、” point. Grouping of students experiment to let the students do, to suffer 5setbacks in the experiment, re-thinking to solve, and finally experience the success. Gravity Measured using a simple pendulum, and some measured values with the actual values vary greatly, from measuring the pendulum length
16、, count the number of processing data to find a cause, and finally correct the errors, to improve the experiment, to get reasonable results. so that the students impressed the results obtained clearly higher than the stresses play “mode of teaching. “Lazy” a little preparation before class. Take full advantage of the lessons in physics teaching to develop students sense of participation and sense of cooperation. Some simple experiments by the students hands-on prep
