Reflections on the establishment of efficient classroom under the background of educational informatization

With the deepening of "school-based revolution", creating "efficient classroom" has become the main theme of "curriculum reform". Applying modern information technology to classroom teaching can make the teaching content abstract and concrete, impossible and possible, silent and vocal, difficult and easy to understand, make students integrate into vivid situations, stimulate students' enthusiasm and initiative in learning, greatly improve students' interest in learning and help improve classroom teaching efficiency.

At present, the new curriculum reform has become a common practice all over the country, and the situation is gratifying; In our county, the research on efficient classroom teaching has also been carried out, and various forms of efficient classroom teaching competitions have been held. However, some teachers don't understand the new curriculum concept in place and lack experience, which leads to the phenomenon that classroom teaching is a mere formality and inefficient. The "efficiency" of "efficient classroom" should not be measured by how teachers teach, but by what students learn and how they learn. In this sense, efficient classroom teaching should be an effective combination of high efficiency and high efficiency.

With the implementation of educational modernization and the popularization and application of high technology, information technology is increasingly applied to classroom teaching. Information technology, with its extensive information and multimedia means integrating sound, image and text, has many incomparable advantages over traditional teaching methods. Using information technology to teach intuitively and vividly can more effectively brew a good learning atmosphere for students, fully mobilize students' various sensory organs, generate positive interest in learning, and change passivity into active acceptance of information. Make classroom teaching achieve unexpected results.

Today, I want to discuss the advantages and functions of information technology in efficient classroom teaching with all teachers.

From a small point of view: the application of information technology in the classroom can reduce the content of teachers' blackboard writing. Environmental protection and no dust pollution have made great contributions to reducing teachers' occupational diseases.

In a big way:

Applying information technology to efficient classroom can turn abstraction into concreteness and effectively solve the key and difficult problems in teaching.

"Efficient classroom" means that in a relatively short period of time, teachers can enable students to acquire more and deeper knowledge and ability, and gain richer experience. Multimedia information technology is vivid and intuitive. Applying it to efficient classroom can create teaching materials that are close to students' reality and suitable for students' interests, which can not only arouse students' initiative and enthusiasm in learning, but also help to complete teaching tasks with high quality and efficiency. We used to have such teaching feelings, and sometimes we will encounter such problems in class. In class, the phenomenon of demonstrating experiments is often fleeting, and students often regret not observing the experimental phenomenon accurately. If the experiment is repeated, it will inevitably lead to a waste of time and materials. Using modern educational media, teachers can repeatedly play the experimental process, and can adjust the size, distance and speed of images according to the actual teaching needs, and guide students to observe with a clear aim, and the effect is very good.

In information technology, multimedia provides shape, sound, light, color, picture and text, which can create conditions for students to accumulate perception. Psychological experiments show that if the presentation of teaching information is purely visual, the students' attention concentration rate is much higher than that of pure auditory presentation, reaching 8 1.7% to 54.6%. If only auditory learning is used, the forgetting rate will be around 40% after three hours and around 80% after three days. If only visual learning is used, the forgetting rates are 25% and 50% respectively. If audio-visual sense is used together, it is 10% and 18% respectively. It can be seen that modern media is of great significance for acquiring and consolidating knowledge. So using it in "efficient classroom" can play a more "efficient" role.

For example, the contents such as "image of wave" and "interference and diffraction of wave" in physics class will be difficult for students to accept because they are abstract if students read textbooks or teachers play and teach them. We can play an animation with video, and show the vibration, propagation, diffraction and interference of waves to students through static, dynamic and fast speed. In chemistry teaching, some experiments are toxic and dangerous, so it is not appropriate to demonstrate them in class. You can play a video through multimedia, so that students can observe it repeatedly to achieve the purpose of understanding and mastering it. In primary school science and technology, the growth process of plants is a very long process. If multimedia is used to simplify the process of plant planting, germination, flowering and fruiting through video, and only highlight the key processes, students will be more intuitive and easier to understand. In geography class, you can also play some scenes that you can't see with your own eyes, such as acid rain, volcanic eruption or earthquake, for students to experience.

Maximize students' interest in learning and enhance their initiative in autonomous learning.

Creating an efficient classroom means taking appropriate forms in an effective space to stimulate students' learning enthusiasm and initiative, so that students can participate in the teaching process and gain effective knowledge and ability "; Confucius, a great educator, said: "The knower is not as good as the doer, and the doer is not as good as the musician. Einstein once said, "Interest is the best teacher". "Over the years, the traditional word-of-mouth teaching mode has dominated the world, and students are not bored, but' turn a blind eye'. Applying information technology multimedia teaching to efficient classroom can inject new vitality into the classroom. Multimedia attracts students deeply with its rich expressive force and strong interactivity, which can attract students' attention to the maximum extent, arouse students' interest, enter the new class smoothly, and achieve concise and efficient teaching effect. For example, when introducing a new class, teachers can give full play to the role of multimedia by playing demonstration experiments, life videos, science and technology short films and other means, thus stimulating students' interest in learning, improving their attention and enhancing their initiative and enthusiasm in learning.

3. Expand the teaching capacity and complete the teaching tasks efficiently.

The traditional teaching mode is that teachers dictate and write on the blackboard, which has slow teaching speed, small information and low efficiency. Applying information technology to efficient classroom can realize high-density knowledge transfer, optimize the processing of a large amount of information and greatly improve classroom efficiency. Graphics are not language, but they are more intuitive, vivid and contain more information than language. Animation uses words to output more advanced information than graphics.
