The first organizer was put forward by Ausubel. This is a strategy put forward by Ausubel in the early 1960s to improve the organization and presentation of teaching materials. Advance organizer is a representative figure of cognitive psychology. An important concept of educational psychology put forward by American educational psychologist Ausubel in 1960 is also one of his main contributions to teaching theory.

According to Ausubel's explanation, when students are faced with new learning tasks, if the original cognitive structure lacks the appropriate upper concepts to absorb new knowledge, or the original concepts are not clear or consolidated enough, it is necessary to design a guiding material to be presented before the learning materials are presented.

It may be a concept, a law or an explanatory text. It can be a concrete model with easy-to-understand language or intuitive image, but it is higher than the material to be studied in the level of generalization and tolerance, and it can build a bridge between old and new knowledge.

This kind of guidance material is called the advance organizer. Organizers in advance can obviously promote students' learning and help them understand unfamiliar textbooks when they learn unfamiliar new knowledge and lack the necessary background knowledge preparation.

The use of advance organizers helps to promote the transfer of learning, and has a significant role in promoting the transfer test items that need to solve problems. If the learning materials only require mechanical memory, the effect is not obvious.
