1, learning pyramid:

Distinguish the types of active learning and passive learning, and different learning methods basically determine the retention rate of learning content and learning effect. The enlightenment to teachers mainly lies in designing different types of learning activities according to the different requirements of learning goals, so as to realize learning goals faster and better.

Learning Pyramid is the research result of Maine National Training Laboratory. It is displayed in digital form, and learners can still remember the content (average learning retention rate) after studying with different learning methods for two weeks. This is a theory of modern learning style. It was first discovered and put forward in 1946 by Edgar Dale, an American scholar and famous learning expert.

2. The Tower of Dell Experience:

Distinguish between abstract experience, observation experience and doing experience. I think this may be put forward by people engaged in training and development, and it also corresponds to the 72 1 model in the field of learning and development. From this point of view, I think this one is more inclined to 70% learn while doing; 20% learn from others, so-called masters take their apprentices and look at excellent people, 65,438+00% training courses and online learning.

Nowadays, many training courses emphasize training camp, practical operation and peer learning, which is based on this learning theory. All kinds of teaching emphasize student-centered, students are the main body of learning, and teachers are the guides and designers of learning. Maybe the lower the pyramid, the closer it is to students. However, it should be noted that higher learning is based on lower learning. Without knowledge, understanding and application, it is difficult to rely on analysis, synthesis and evaluation.

Learning experience is divided into concrete and abstract, and it is proposed that learning should develop from visual image to abstract thinking, which is in line with the law of human cognition. In the transition diagram of "tower of experience" from concrete to abstract, audio-visual teaching materials are at the more concrete end, which constitutes the theoretical basis for the application of audio-visual teaching materials in teaching.

This paper puts forward the theoretical basis for the classification of audio-visual teaching materials, that is, it should be based on the concrete or abstract degree of learning experience it can provide. Emphasis is placed on the classification according to the role of teaching media in the teaching process, rather than simply enumerating. This basic classification idea, which seems very simple at present, lays a foundation for the classification research and selection of teaching media in the future.
