Briefly analyze the advantages and disadvantages of various teaching media

When communicating with many teachers, they have listed the advantages and disadvantages of the use of teaching media, which is worthwhile for fellow teachers in Guangfa to learn from:

What are the advantages?

1, teaching activities in the process, with advanced e-learning media can really improve teaching efficiency.

2, from the theoretical, visual, auditory media resources, become a cognitive tool for students, so that students in the media "function" to obtain information, processing information, understanding things, and cultivate the ability.

3, the media can be used to create a situation to stimulate interest in contact with new knowledge; teaching new knowledge of the new teaching time, the media can be used to anatomize the difficulties, highlight the key points, solve the doubts, drumming up the passion to explore new knowledge; consolidate the new knowledge of the reinforcement of the time, the media can be used to reproduce the context of the rationality of the categorization, application of the expansion to improve the mastery of the new knowledge of the ability to do so.

4, the use of visual, auditory media, often can be poor mental state into a good learning state, or to maintain the original good mental state, to ensure that the main learning effectively, the natural teaching effect will be the best.

5, the advantages of modern teaching media, it is vivid image, expressive, wide range of uses, especially through the charts, text, sound, like multi-level and multi-angle presentation of the teaching content, creating a three-dimensional teaching space, to strengthen the students listen to the visual sensory *** with the same stimulus to facilitate the students' comprehension and literacy more profound.

Drawbacks can not be ignored:

1, although intuitive and time-saving, but after all, is not a real student hands-on experiments, the student's role in the main body is completely stifled. Traditional teaching media compared to modern media have their insurmountable limitations.

2, heavy quantity, light quality. Many teachers one-sided pursuit of a lesson in the process of teaching activities as much as possible with modern advanced media, it seems that the more e-learning media used in the class the better, the recordings, projections, television, computer full set of move out, kind of use. As a result, the whole class has become a display of modern teaching media, so that the teachers are busy, the watchers are dazzled, the listener is panicked, and the role of the real media in teaching and learning to reduce. Some even make a class all multimedia courseware, from beginning to end of the whole computer-controlled operation, the big screen in accordance with the designer's ideas demonstrated in the end. As a result, students in the teaching of the main position is not, in the teaching of the activities canceled, teachers and students of two-way communication has been diluted, reducing the application of advanced media, "quality", classroom teaching is not effective.

3, heavy "bring", light technology. The development of advanced media resources, the production of advanced media courseware is the need for technology. The process of design itself is the re-creation of teaching resources, the process of re-innovation of the teaching content, demanding, difficult and laborious, but in order to maximize the use of will pursue the "bring" policy, the rigid use of ready-made e-learning materials and resources. Do not care about the quality of the "brought" teaching software. As a result, the operation of the mismatch "jam" phenomenon is often seen; sound or image fuzzy classroom order caused by chaos; textbook knowledge is simple and repetitive serious impact on the enthusiasm of many students. So all these things, leading to the advanced media in the process of teaching activities in the value of a serious depreciation.

4, heavy "new wave", light tradition. Some teachers over-exaggerate the role of modern teaching media, that as long as the audio-visual, projection, computers into the classroom, for the teaching process, teaching all the problems will be solved, that the more "fine, new" advanced media, the more you can improve the efficiency and quality of teaching and learning, and as a result of the traditional media of teaching (such as: board drawings, wall charts, model, As a result, the traditional teaching media (such as: drawings, wall charts, models, experiments, etc.) out of the classroom teaching and learning stage. As a result, teachers and students can *** with the completion of the board with a slide to replace the board, should be seen to touch the physical model with a physical projector to replace.
