Interest is the internal force to promote knowledge, which can generate strong learning motivation. With interest in physics, you will have a self-demand for learning from your heart, a strong thirst for knowledge, and consciously improve your ability to learn physics. Interest in physics can be cultivated from the following aspects.
1. Stimulate physics learning interest through observation and experiment.
Physics is a highly experimental subject. Physicists study physical problems in various ways, but the most basic one is observation and experiment. Almost all the laws of physical phenomena are discovered through experiments. Experiments play a key role in understanding and mastering physical knowledge. For example, when talking about recoil movement, you can simulate the demonstration of a cannon. (l) Make a small hole in the upper part of the bottle as the ignition hole, and screw it with paper to block it.
(2) Inject 10- 15 ml dilute sulfuric acid, a small amount of copper sulfate solution and 2 ~ 3g zinc particles into the vial. Copper sulfate is added to improve the chemical reaction rate of dilute sulfuric acid and zinc particles.
(3) Put the cork on the smooth floor.
(4) aim a 20 cm long paper stick at the small hole and ignite it immediately. Just listen to the "clang", the rubber plug shoots a distance of more than ten meters, and at the same time, the car bounces back more than one meter.
This novel and unique experiment greatly aroused students' curiosity, stimulated their enthusiasm and initiative in learning physics, and also stimulated their interest in learning.
2. Stimulate interest in physics by studying physical historical materials and historical stories.
Learn the spirit of independent thinking, hard study and innovation of senior physicists, and overcome the difficulties in physics learning with tenacious will.
3. Overcome physical problems and stimulate interest in learning.
Through students' independent thinking and unremitting efforts, a series of physical problems are solved by using the physical knowledge they have learned, which enhances students' confidence and interest in learning physics. When some problems are solved by their own efforts, students feel extremely gratified.
Second, mastering methods is the key to improving ability.
Mastering methods can accelerate the process of transforming knowledge into ability.
1, using the method of comparative analysis, deeply understand the essential differences of related physical concepts.
As we know, most physical concepts are based on experiments, put forward empirical formulas, and then formed through strict theoretical argumentation. Concept is the basis of judgment and reasoning, and it is also the basis of studying physical phenomena and argumentation. Most of the problems that often appear in the study of physical phenomena and arguments are related to conceptual errors, and conceptual confusion is more common in conceptual errors. Seriously affect the accuracy of physical conclusions and the logic of argument. In the process of learning concepts, we often perceive and understand the same factors of related concepts, but it is not easy to perceive and understand the essential differences between concepts. For example, the content of Newton's third law is easy for students to perceive, but when analyzing the force of an object, they often confuse the balance force, the acting force and the reaction force. The reason for confusion is that they all act on a straight line, equal in size and opposite in direction. If they knew their differences, they wouldn't be confused. Their differences are as follows:
(l) The acting force and reaction force act on two different objects, and the balancing force acts on one object.
(2) Action and reaction are two forces with the same nature, and balance force is two forces with different properties. Therefore, we should pay attention to the comparative analysis of related concepts and deeply understand their essential differences.
2. Clarify the logical relationship of physical concepts by classification and generalization.
In learning, we should pay attention to classification and generalization, and classify related concepts with the help of charts.
For example:
3. Research on problem-solving methods to cultivate students' ability to analyze physical problems with mathematical knowledge.
Most of the time spent studying physics is spent on solving problems, and the assessment of grades also depends on problem-solving ability, because problem-solving ability is the comprehensive ability of students to analyze and solve physical problems by using the mathematical knowledge and skills they have learned, which reflects the quality and level of a student's physical thinking. Therefore, it is necessary to study the method of solving problems, especially the method of solving multiple problems, so as to cultivate students' flexibility, multidirectional and originality in solving problems.
4. Master the method of "breaking the contract" and constantly consolidate what you have learned.
The method of "breaking the agreement from the blog" is to sort out the knowledge structure, that is, systematize and organize, and form a knowledge system that is easy to remember. The specific method is to review and summarize the learned knowledge in time, and weave various comparison charts, formula tables and problem-solving thinking modes through synthesis, generalization, comparison and classification, so as to have a more complete understanding of the learned knowledge and make the learned knowledge materials from thick to thin. Generally speaking, it is easy to master and remember, which makes the knowledge more solid and helps to develop the habit of defining conceptual problems, calculating ideas and reasoning problems.
Thirdly, inspiring thinking is the basis of cultivating self-study ability.
Thinking ability is the core of intelligence. To promote the development of intelligence, it is necessary to open the door of students' thinking, keep the brain in a positive thinking state and integrate what they have learned. Only in this way can self-study ability be relied on and thinking can be further developed.
To cultivate students' thinking ability, teachers must be good at "asking questions" to arouse the waves of exploring questions in students' hearts, so that students can learn, explore and forge ahead with these questions, thus cultivating students' independent thinking ability.
Teachers are not only "suspicious", but also emphasize the cultivation of students' ability to find and ask questions, which meets the requirements of the times to cultivate pioneering talents. Teachers' "doubts" only stimulate students' thinking, and students' "doubts" are the starting point for them to realize the leap in understanding textbooks. In a sense, it is more important for students to have their own ability to find problems than to cultivate their own ability to solve problems.
Fourth, strict training is a means to cultivate application ability.
Any kind of ability can be truly acquired through repeated practice. A boxer taught his apprentice to clench his fist, and a musician taught his apprentice to shut up. Physics is a science with a logical theoretical system. The content of physics is rich and complex. It has abstract concepts and laws, as well as experimental methods and mathematical tools. At the same time, there are many practical contents related to production and life. Therefore, in the process of learning physics, students must master the internal relationship between old and new knowledge, and train students to master and use elementary mathematical tools to solve physical problems in a planned and step-by-step way. It is useless if we simply memorize or recite some definitions, laws and formulas when studying physics without understanding their physical meanings. The sum of the essential attributes of a physical concept is the connotation of the concept. The sum of phenomena reflected by the concept is the extension of the concept. Only by fully understanding the connotation and extension of the concept and organically linking them can we correctly understand the essence of the concept. The same is true of physical laws and formulas. Only through the strict training of repeated use-positive, negative and variable use, can we accurately understand the inevitable and organic connection and transformation between conditions and conclusions, and can we firmly grasp these laws and formulas and use them flexibly to achieve the purpose of digestion.
In a word, with the development of modern science and technology, the requirements for human intelligence are getting higher and higher. In order to meet the needs of the four modernizations, it is very important to cultivate architectural talents with high scientific and cultural level and comprehensive quality.
