原文请参见国家引发的有关资料Teaching Program of Physics of Full-time Ordinary Senior Middle School of China(Tentative revised edition)ﻩPhysics is a basic science and the foundation of development of the whole natural science and modern technology, so it plays an indispensable part in the knowledge-oriented economy Physics knowledge is widely applied in modern life, social production, science and technology. The physical approach to research is of universal significance to the exploration of the nature. For students at the stage of senior middle school, the learning of basic knowledge of physics and its experimental skills, the training of scientific methods and scientific thinking and the nurturing of scientific attitude and scientific style, are very important in enhancing their cultural quality, enabling them to adapt themselves to modern life and continue the study of science and technology. ﻩPhysics course is a major course in ordinary senior middle school. The teaching of physics should follow the strategic thinking of “education should face modernization, face the world and face the future”, implement the educational principle of the state and make better contributions to the fulfillment of the tasks and the aim of ordinary senior middle school。
I. Teaching Aim(1) To let students learn the basic knowledge of physics comprehensively and its practical applications, and understand the relationship between physics and other branches of learning, and the relationship between physics and technological progress and social development as well2) To let students get training in scientific methods and cultivate their abilities in observation, experimentation, scientific thinking, problem analysis and solution. (3) To foster students’ aspiration towards science study and their down—to—earth attitude, let them build up a sense of innovation and offer education in dialectical materialism and patriotism as well. II. Course Arrangement This program provides the teaching contents and requirements of two categories of physics so as to meet the demands of students with different interests and advantages. Compulsory Physics Course It is the physics in the basic requirement, and compulsory for all students, called Class I Physics for short.Compulsory Plus Elective Physics Course It is the physics in the higher requirement, suitable for students with a better foundation, called Class II Physics for short。
III. Determination of Teaching ContentsThe teaching contents should help to enhance the students’ quality in science and culture, and help their further study so as to meet the needs for talents in the 21st centuryThe ordinary senior middle school serves a high-leveled basic education. The physics in senior middle school should emphasize the foundation and take the most important and most fundamental knowledge as the main contents of the course The teaching contents should be constantly renewed with the times. The relationship between classical physics and modern physics should be handled well, the contents of modern physics should be added properly and attention should be paid to the infiltration of viewpoints of modern physics in teaching of classical physics so as to open the students’ thinking and vision。
Physics knowledge has wide applications and the teaching contents of senior middle school should include the practical knowledge closely connected to fundamental knowledge Students should be enlightened to understand the physical principles in practical problems Achievements in modern science closely associated with the fundamental knowledge should be introduced to them Students should not only know the conclusions in physics knowledge, but also learn about the process of the generation and development of knowledge and know how mankind’s cognition on the nature has been deepening step by step. Some historical background and the evolution of physical thinking should be introduced in the teaching as well. The arrangement of the teaching contents should be reasonable in quantity and degree of difficulty, and allocation of teaching hours should be flexible so as to guarantee students’ lively and active study and development。
IV. Points of Attention in Teaching(1) Guide students in their enthusiastic and active study and cultivate their habit and ability of independent thinkingConstantly reform teaching methods, carefully study students’ psychological characteristics and law of cognition, be good at enlightening their thinking and arouse their interest in learning so as to enable them to acquire knowledge and abilities enthusiastically and actively. Encourage students to air their views and cultivate their questioning habit. Start from the actual conditions, suit the teaching to the ability of the students, and raise different demands for different students so as to enable them to learn and develop in an enthusiastic, initiatively and effective way. Foster the students’ habit and ability to think independently. The teacher should not lecture too intensively, should leave room for students to think, probe and explore for themselves. Give encouragement and guidance to them in their active and independent probing into questions. Guide them to master the correct learning methods, learn how to read the textbook properly and sum up the knowledge they have learned。
Try to improve students’ ability to acquire new knowledge and enable them to collect information and broaden their knowledge independently (2) Stress the teaching of physical concepts and lawsEmphasis should be given to the process of establishment of the concepts and laws, and to the understanding of them Enable students to be clear about the physical facts on which the concepts and laws are based, understand the meanings of the concepts and laws, understand the conditions to which the laws apply, and know the distinction and connection between relevant branches of knowledge. The teaching of concepts and laws should be clear in the way of thinking so as to make students know their origin and development, really understand the truth in them and master the methods to research。
Emphasize the application of the concepts and laws in real life, enable students to use the physical knowledge they have learned to explain phenomena, analyze and solve actual problems so as to consolidate their knowledge in its application, deepen their understanding of the concepts and laws, and raise their ability to analyze and solve problems in real life. What is the main and what is the secondary should be clearly distinguished from each other in teaching, and the key points should be emphasized。
Key concepts and laws should be taught better and should be fully used to develop the students’ intelligence, cultivate their ability and foster their spirit of science At the same time, pay attention to the step-by—step development, for knowledge should be expanded and deepened step by step and ability should be improved step by step as well. The emphasis in class teaching should be laid on the understanding of the concepts and laws, instead of doing too many exercise questions Of course, it is necessary to do a certain number of questions in physics study, but the quantity and degree of difficulty of the questions should be suitable for the actual condition of the students, and it is not proper to seek the number of questions. Let students understand that, independent thinking is needed in problem solving; mechanically application of some set type is not good. Only in this way can their ability can be improved。
3) Emphasize demonstration and students' experimentationObservation of phenomena, demonstration of phenomena and experimentation by the students may enable the students to acquire specific and clear knowledge, which are the foundations for understanding of concepts and laws. Observation and experimentation play an indispensable role in cultivation of students’ abilities in observation and experimentation, fostering of their down—to—earth attitude and arousing of their interest in learning. Therefore, it is necessary to strengthen demonstration and students’ experimentation by all means. All the demonstration experiments and students’ experiments specified in this program should be done well。
In addition to demonstration experiments, the contents of demonstration should also include hanging charts, models, projections and slide shows, etc. Modern teaching means such as the computer should be brought into full play.The requirements in the experiments by the students must be attained. Schools with better conditions should add some experiments for the students, especially some experiments of an exploring nature. The teacher should try his best to carry forward students’ enthusiasm and initiative in the experiment, and offer better guidance to them. Encourage students to think carefully, use both their hands and brains, be able to operate independently and be good at cooperating with others as well. Teach students to abide by the rules of the laboratory. (4) Strengthen the cultivation of abilitiesIn teaching of physics, attention must be paid to the cultivation of students’ abilities in many aspects。
Strengthening the cultivation of abilities is a major task in physics education. That traditional teaching idea of purely passing on knowledge should be done away with. On the other hand, it is not good either to instill the methods and abilities into the minds of the students as a kind of new knowledge, which cannot really improve their abilities, either. The cultivation of students’ observing ability and experimenting ability should be done through observation of phenomena and demonstrations, and through their own experiments。
The observing ability to be cultivated basically means the following aspects: able to observe on purpose, able to distinguish the main features of the object of observation, and able to know the changing process of the object and its condition for change The experimenting ability to be cultivated basically means the following aspects: able to know the purpose of the experiment clearly, able to understand the principles and methods of the experiment, able to use the instruments correctly, able to control the experimenting conditions and deal with the troubles in the experiment, able to analyze the data gained from the experiment and draw a correct conclusion, able to know the concepts of the error and the significant digits, and able to write the experiment report independently and briefly. Students' thinking abilities of abstracting, generalizing, analyzing, synthesizing, deducting and judging and their verbal abilities of expressing themselves in scientific language should be developed through the formation of concepts, the drawing of laws, the establishment of models and the application of knowledge and so on. Students’ ability to use mathematics to solve problems should be developed, which mainly includes the following aspects: able to understand the physical meanings of the formulas and the pictures, able to use mathematics to do logical deduction and draw conclusions in physics. They should learn to use pictures to express and solve problems。
Emphasis should be laid on both the quantitative calculation and the qualitative and semi-quantitative analysis Students' abilities of problem analyzing and solving should be fostered through the application of their knowledge. They are required to be able to use the concepts, laws and models they have learned to carry out specific analysis for actual problems, clarify their physical process and conditions, and find out the thinking clue and the approach to solve the problems, In this way, they will develop their power to analyze and solve problems flexibly. (5)Maintain a close tie with practiceThe teaching of physics should be closely connected to practice and enable students to understand and apply their knowledge in the combination of theory and practice. Here the practice refers to natural phenomena, modern life, scientific experimentation, practical problems in all industrial sectors and the development of modern science and technology, etc. Attention should be paid to the commonly concerned social and economical problems of the present time, such as energy sources, the environment and so on, so as to make students understand the relationship between physics and technological progress and social development, and know the role of physics from a broader vision。
Cultivate students' sense of application, paying attention to both the discoveries of the scientists and their inventions Encourage them to show concern for practical problems and aspire to apply their physics knowledge to the practical life (5) Carry out theme—researchThe theme-research in the senior middle school is an important way to cultivate students' ability of use their knowledge comprehensively, their ability to collect and handle information, their ability to analyze and solve problems, their ability of verbal expression and their ability to cooperate and coordinate with each other. This activity will also help them develop the habit of independent thinking and stimulate their sense of innovation. A theme-research should mainly focus on the cultivation of those abilities and senses, rather than on the learning of a specific knowledge. The teacher should offer guidance to the theme—research, but should avoid giving specific steps and methods. It is necessary to encourage students to adopt different methods and put forward different opinions.The theme—research may be roughly classified into several types such as explorative physics experiments, fabrication of things in science and technology, study report of new scientific and technological problems, social investigation, vision-broadening study and so on. In the appendix, we have suggested some examples of theme-research for teachers and students to choose, and other topics may be suggested, too. The teacher may recommend different types of research to his students according to their own merits and interests.The result of a theme—research may be a short treatise, or a science report, or a self-made instrument or device.The theme-research should be carried out both in class and outside class. The program has allocated 4 hours for each theme, and it must be guaranteed in the teaching. There should be 2 hours for students to report and exchange ideas. (6) Give play to the educational function of physics course in the field of ideology and moral attitudeThe physics course should guide students to believe and love science, and let them think about the relationship between science & technology and human society. Let students receive the education in dialectical materialism unconsciously together with the learning of knowledge, cultivate their down-to-earth scientific attitude, and educate them to start from practice, respect facts and do according to the objective laws.Introduce the important events in the development course of physics and the stories of scientists to inspire their sense of innovation。
Introduce the contributions our country made to science and technology in history, and introduce the achievements our country has made in socialist construction and in modern science and technology so as to develop their patriotic sentimentV. The Teaching Contents and Requirements of Compulsory Physics CourseNote(1) The compulsory physics course is the course in the basic requirement, its contents and requirements should aim to improve students' scientific and cultural quality and its contents should include the main aspects of physics knowledge。
2) In the compulsory physics, emphasis should be laid on the development of students' observing ability, scientific thinking ability and the ability to adapt themselves to modern social life (3) There are two levels for the teachingLevel A: It is the lower level. The contents of knowledge listed in this level should not be dealt with in detail at the stage of senior middle school, or they have already been discussed in detail at the junior middle school stageLevel B: It is the higher level with higher requirements。
The contents marked with * are ones to be chosen and should be used as much as possible in the teaching, at least 4 hours should be used for it (4) In the following “demonstration” column, what have been listed are mainly the demonstration experiments. Other demonstration means should be determined by the teacher himself. In order to increase the students’ chances of practical operation, some demonstration experiments may be arranged as experiments in class, in the manner of experimenting while teaching, so as to help students observe phenomena carefully and improve their observing and experimenting abilities. This kind of experiments in class normally are qualitative in the main, and has no high requirement in the quantitative aspect. (5) According to the teaching plan, the total hours of compulsory physics course is 158, and they should be allocated in the following way: 101 hours for lecturing (including students’ experiments in class), 17 hours for students' experimentation, 16 hours for theme-research (4 themes), and 24 hours for flexible use (including the time for students to arrange themselves).The following are the teaching contents to be finished before the end of the compulsory physics course and the requirements for them.1.
