1, which can increase the amount of classroom information.
Phenomenon and other real-life knowledge, students have not accumulated much, which is relatively poor, and can be reproduced well by using information technology. Provide students with a lot of perceptual materials in a short time, enrich their perceptual knowledge, and make reasonable guesses and inferences for them. Nowadays, science teaching requires students to store a lot of life science knowledge in their brains. Some things involved in teaching provide help. For example, students can watch boating, skating and swimming when they say "the role of force is mutual". When learning "the speed of object movement", by showing the footage of swimmers struggling in the Olympic Games, students' intuitive understanding of some phenomena can be deepened, so as to stimulate students' senses, arouse their enthusiasm for learning and stimulate their curiosity, which is conducive to the smooth progress of teaching. The application of information technology can break down the barriers of time and space. Through the analysis, induction and reasoning of a large number of facts and experiments, scientific concepts and laws can be obtained.
2, conducive to the understanding of knowledge.
In teaching, we will encounter some abstract knowledge and be influenced by experimental conditions. It is difficult to achieve the ideal teaching effect with traditional teaching means and methods. The rational use of information technology can visualize and concretize scientific knowledge, turn abstract into concrete, turn static into dynamic, and help students understand knowledge.
The rational use of information technology is conducive to the change of the speed of change. For example, energy conversion, especially kinetic energy into elastic potential energy, the deformation of the ball occurs in a very short time, which is not easy to observe. The computer can simulate the deformation process of the ball in "slow motion" and then release it, which is more intuitive and can be displayed repeatedly.
The rational use of information technology is conducive to the transformation of observation space. For example, we can't see the movement of molecules, and we can't see the force between molecules. As long as students imagine that the molecules in the model are constantly moving irregularly, the gaps between molecules and molecules of different colors enter the flash when different objects contact, the long-term diffusion phenomenon can be shortened to a very short time. Overcome the limitations of time and space. Enlarge micro knowledge into macro knowledge, build a bridge for students to explore micro knowledge, skillfully guide students to analyze its essence, cultivate students' micro imagination ability, help students understand, and make vague knowledge clear. Deepen the impression of knowledge. Can quickly break through the teaching difficulties.
3. It can broaden the classroom teaching space.
Optimizing the traditional teaching mode, in some exploratory experimental teaching which mainly focuses on students' guessing, discussion and experimental inquiry, students often feel pressed for time because there are many contents that need students' active participation. If information technology can be properly applied in these classes, it will help to improve the efficiency of classroom teaching. In the experiment of exploring "what factors are related to the heat absorbed by an object", in order to ensure the smooth progress of the inquiry, teachers must guide the assembly of experimental equipment involved in the experiment, the contents to be observed and recorded in the experiment and related matters needing attention. If the traditional teaching method is used, it is time-consuming and easy for students to listen to this, forget that and pay attention to this. Therefore, in teaching, we should first use information technology to display the experimental device on the big screen. Then click the mouse, and the main points will be fixed on the big screen with animation and word change. When students are operating, if there are any problems, they just need to look up and continue the experiment, and the effect is very good.
In learning, there are often problems or exercises with a large amount of reading and many contents. It takes time to lean against the blackboard in class. When these things happen, we can type the problem first and then project it on the big screen. Writing on the blackboard is effective and time-saving, and the answers can be presented in vivid forms such as animation to improve students' interest.
The pictures in the textbook can be scanned and stored, which is very convenient to use when making slides or asking questions about a certain knowledge point in the book. It is very helpful to solve knowledge difficulties, turn abstraction into image, turn static into dynamic and improve classroom efficiency.
4. It is beneficial to cultivate students' innovative thinking.
Internet helps to cultivate students' thinking ability. Using network and multimedia technology, we can build an informative and reflective learning environment and tools for students to explore freely, which is very conducive to the formation and development of their critical and creative thinking. It is a new requirement for teachers to tap students' innovative potential, protect their innovative personality and cultivate their innovative ability. Information technology provides conditions for teachers. When students have their own views on a scientific phenomenon, they can put forward or discuss with students or provide discussion and exchange through the computer network in time, and teachers can provide answers or find answers online by themselves. Such multi-question communication will make students' thinking more active, help cultivate students' innovative consciousness, and realize modern teaching thought with students as the main body and teachers as the leading factor. Broaden students' horizons, cultivate students' self-study ability and achieve the best teaching effect. Allow students to question textbooks, put forward different opinions, refute teachers, break through classics and deviate from classics. When teachers can't get answers to some questions, encourage students to explore by themselves and search online, so that students can learn to better use information technology and tap their innovative potential.
5. It can broaden the knowledge of teachers and students.
The application of information technology in education and teaching has surpassed the traditional teachers and provided a broad space for teaching activities. There are many new knowledge points in the new curriculum standards, such as "science in life", "scientific world", "thinking and discussing" and "thinking and doing". We should not only pay attention to life, but also understand it. There is a lot of knowledge in life that can't be understood one by one, and the knowledge in the scientific world and environmental protection depends on web browsers to query. For example, the information of "superconductor and semiconductor" has been applied in high-tech life, and the causes of "nano-materials and technology" and "greenhouse effect" have been solved. Encourage students to look up information online by themselves, and improve their interest in exploring scientific knowledge through their own understanding.
The application of information technology can make up for the limitations of traditional teaching methods, break the single teaching mode, realize the diversification of teaching and learning, and improve teaching efficiency. However, in order to make information technology play its powerful role in science teaching, we must pay attention to the rationality of the number selection and combination of various media of information technology. When using information technology, we must be targeted according to the actual situation of teaching materials and students' cognitive characteristics, and pay attention to the organic combination with traditional teaching methods to achieve the best teaching effect. Of course, to combine the application of information technology with traditional teaching best, it needs to be explored constantly in teaching.
