How to Cultivate Students' Scientific Concept in Physics Teaching

Physics is a natural subject with a long history. With the development of science and technology and the progress of society, physics has penetrated into all fields of human life. In the development of modern science and technology and science and technology education, physics plays a vital role in enhancing students' awareness of science and technology and improving their understanding that science and technology are the primary productive forces. So, how to cultivate students' awareness of science and technology in physics teaching?

First, give full play to the role of classroom teaching as the main channel.

Classroom teaching is the main position for teachers to spread physics knowledge and the main way for students to acquire physics knowledge. To strengthen science and technology awareness education, we must start with classroom teaching and give full play to the role of classroom teaching as the main channel.

1. Highlight the practicality of knowledge. Physics is a practical science, which is closely related to industrial and agricultural production and daily life. In teaching, teachers should combine the specific teaching content, closely link with the actual production and life, and highlight the practicality of knowledge. Physical knowledge and laws are summaries and abstractions of natural phenomena. Through the introduction of these knowledge, students are more aware of the position and role of scientific knowledge in daily life, industrial and agricultural production and even high-tech fields, so as to believe and love science more, and establish a good sense of science and technology and the idea that science and technology are the first productive force.

2. Pay attention to the teaching of physics history. The history of physics development is an important part of physics teaching. Through the teaching of the history of physics development, students can not only understand the history of physics development and the typical deeds of some famous physicists, but also cultivate their good sense of science and technology. Teachers must strengthen the teaching of the history of physics in practical teaching, and choose appropriate materials of the history of physics according to the specific teaching contents, such as Galileo's free fall experiment, Newton's law of motion, Einstein's theory of relativity and so on. And seize the opportunity to educate students on the history of physics. At the same time, in practice teaching, students can be properly introduced to the great achievements China has made in aerospace and high-tech fields since the founding of the People's Republic of China, especially since the reform and opening up. Through the introduction of these knowledge, students can better understand the attitude of scientists towards science, learn scientific methods and their spirit of loving and dedicating themselves to science, understand the great power that science and technology have brought to social development and modernization, establish national self-esteem and self-confidence, and get a good education on scientific and technological awareness.

3. Strengthen experimental teaching. Strengthening experimental teaching is helpful to cultivate students' hands-on operation ability, observation ability, independent analysis and problem-solving ability, as well as their scientific attitude of seeking truth from facts, innovative consciousness and creative ability, and at the same time, educate students on scientific and technological awareness. According to my teaching experience of more than ten years, the author thinks that strengthening experimental teaching can start from the following aspects: (1) reforming classroom demonstration experimental teaching. Some demonstration experiments are changed to the form of students' demonstration on stage or experiment while talking, so as to provide more hands-on opportunities for students. (2) Pay attention to students' experimental teaching. In students' experimental teaching, teachers require students to conduct it in the form of "preview-experiment-observation record-analysis and discussion-summary report", organize students to seriously discuss the problems existing in the experiment, analyze the reasons, find out the solutions to the problems, and write experimental reports realistically according to the actual situation of the experiment, so as to cultivate students' serious and realistic scientific attitude and ability to analyze and solve problems independently. (3) Strengthen the teaching of experimental exercises. In the teaching of experimental exercises, the program of "designing the scheme by yourself-discussing the scheme-selecting the scheme-experimental verification-summary report" is mainly adopted, so that students can participate in the experimental design and pass the experimental verification. This can better cultivate students' awareness of scientific research, innovation and creation.

Second, actively organize extracurricular activities in physics.

Physics extracurricular activities are also an important position to strengthen students' scientific and technological knowledge and consciousness education. Compared with classroom teaching, extracurricular activities are more flexible and selective.

1. Extracurricular fun experiment. According to students' knowledge base, interesting physics experiments are carefully designed, so that students can complete experiments such as "dropping bombs on airplanes", "jet rockets" and "boiling water in paper pots". Through these experiments, we can not only stimulate students' interest in learning and exercise their practical ability, but also help students get rid of superstition, emancipate their minds and establish a scientific outlook on life and values.

2. Small technology products. According to the actual situation of the school, actively organize students to use extracurricular activities to carry out scientific and technological production activities, such as homemade bell, homemade parallel light source, pinhole camera, periscope, homemade measuring cylinder, stair light switch circuit, etc. , and organize exhibitions and evaluations. The development of scientific and technological activities can not only train students' scientific and technological production ability, but also lay a good foundation for students to make simple teaching tools after work in the future.

3. Guide students to read popular science books. Teachers should guide students to read relevant popular science books according to their knowledge base, so that students can learn more about scientific knowledge and the new trend of scientific and technological development, increase their scientific and technological knowledge, and organize regular activities such as "practical physics knowledge contest" to arouse students' enthusiasm for learning and reading, so that students can master more scientific and cultural knowledge and cultivate their scientific and technological reading ability.

4. Hold lectures on popular science knowledge. Scientific and technological knowledge is closely related to social development, production and life. When holding a lecture on science and technology, we should carefully select materials or write a speech according to relevant materials. According to the materials collected at ordinary times, we can collect materials such as military science, aerospace technology, communication technology, space technology, examples and contributions of scientists, and educate students on ideological and moral and scientific quality. You can also contact physics in social life, let students collect information, make special presentations in class, and introduce the application of popular science knowledge and physics knowledge by blackboard newspaper.

5. Organize social investigation activities. In social investigation activities, students can use the knowledge in textbooks to solve practical problems in life and production. For example, after learning "hydropower and wind energy utilization", they can investigate local energy use and environmental pollution, and put forward suggestions for improvement. They can also investigate noise pollution, the use of heat engines, electricity consumption in rural areas and so on in combination with the contents of textbooks.

In a word, strengthening the education of students' scientific and technological awareness and cultivating students' good scientific and technological awareness are the needs of scientific and technological development and the needs of cultivating qualified talents in the new century.
