Urgent need for a speech on the experience of physics in the second year of junior high school 10

Physics is very simple.

You've got a good 1234 column, and you can just write it with that.

What methods should be used to achieve twice the result with half the effort when learning junior high school physics?

1.Pay attention. When learning physics, we should first pay attention to observing the physical phenomena given by the teacher and the textbook, such as the questions raised in the textbook, the ** given, the experiments and the teacher's demonstration experiments.

The main aspects of observation are: the conditions under which physical phenomena or facts arise, the forms in which they manifest themselves, such as motion, deformation, temperature changes, results, etc. Secondly, we should consciously cultivate our habits and interests in observing physical phenomena in our lives.

2.It is necessary to pay attention to learning and summarizing the problem-solving methods of physics to help oneself gradually improve one's thinking ability. There is no special chapter in physics textbooks that introduces the learning methods of physics.

However, it can be said that the whole textbook is about the problem solving method of physics. This is because when textbooks explain physical concepts, laws, and formulas, they follow the steps of physics to solve problems. That is, questions are generally raised first, and then carried out through experimental research, observation, analytical reasoning, generalization and other steps.

Therefore, in the whole process of physics learning, while learning the problem-solving steps of the textbook, you should also pay attention to thinking to see if you can come up with experiments, methods and steps to solve the problem that are different from those in the textbook. In this way, while learning to inherit the thinking achievements of predecessors, they can also exercise and improve their ability to solve problems and innovate ability.

3.Pay attention to the method of memorization. Although learning junior high school physics requires attention to cultivating thinking ability, it is also necessary to pay attention to memory, and to memorize on the basis of understanding, rather than mechanical memory.

When memorizing, we should pay attention to finding patterns and characteristics, and be accurate. It is necessary to accurately memorize the various definitions, the literal expressions of the laws, and the "units" of various physical quantities. This is conducive to helping us form the ability to express physical words and language.

One of the biggest differences between physical formulas and mathematical formulas is that each factor in the formula has a "unit". Therefore, when memorizing the expressions of physical formulas, it is important to remember the physical units of each factor.

4.It is necessary to pay attention to experimentation and do as many experiments as possible. If you can't do experiments, you can't say that you have learned physics well.

Experimental hands-on ability mainly refers to hands-on ability such as observation, operation and production. When you start learning physics, you can pay attention to how the teacher does all kinds of demonstration experiments, such as the steps of the experiment, what to do first, what to do later, and the method of the experiment. When doing experiments, carefully experiment and practice according to the experimental steps and methods required by the teacher.

We should actively find ways to do the exploratory experiments and small productions on learning physical concepts and laws given by teachers and textbooks. This is very beneficial for enhancing hands-on ability. In addition, you can design your own experiments.

For example, if you want to design the experimental procedures and methods implicit in the illustrations and exercises in the textbook, you can design the experimental procedures and methods by yourself and conduct experiments. This develops your ability to innovate and solve problems hands-on.

Listen carefully in class, and the most important thing is to do exercises to consolidate.

When I started studying high school physics, I felt very different from junior high school physics, as if there was a gap between high school physics and junior high school physics. So how can you bridge the chasm and learn high school physics well? I think we should start with the difference between the knowledge structure and characteristics of high school physics and junior high school physics, and find new learning methods.

1. The difference between the characteristics of the knowledge structure of high school physics and that of junior high school physics:

1. The research problems of junior high school physics are relatively independent, while high school physics has a knowledge system. The first semester of the new senior high school.
