Annotating the levels of teaching

According to our definition of knowledge levels, we divide knowledge into the following four levels: the first level is the factual and procedural knowledge, the second level is the knowledge of disciplinary concepts, the third level is the knowledge of disciplinary big picture, the fourth level is knowledge on the general ways of thinking and the methods of teaching and learning.

Correspondingly, we also divide the teaching activities into four levels: at the first level, one teaches the first level knowledge, or teaches each level of knowledge in isolation, and does not use up-down and left-right connections to promote meaningful learning of knowledge; at the second level, one teaches the second level knowledge via the connections between the first level and the second level, and also via the connections among the second and the higher level knowledge, and the connections within the second level; at the third level, one teaches the third level knowledge via the connection between the third and fourth levels, and also the connection between the third and the lower levels of knowledge, and the connections within the third level; at the fourth level, one teaches the fourth level of knowledge via the connections between the fourth level and the lower levels, and also the connections within the fourth level.

In this project, we need to encode the teaching level of the video records of actual classroom teaching according to the above concept of the level of teaching. This first requires our annotators to be able to see high-level knowledge by themselves, and to thinking in terms of the up-down and left-right connections.

Once we have a certain amount of labeled data, we can try to build an artificial intelligence algorithm to complete the labeling, and at the same time design a scale that measures the level of teachers’ teaching activities based on the labeling experience.

This research work can help us see the level of knowledge imparted by teachers in their daily teaching, so it can further assist teachers to improve the level of knowledge taught in classroom, or at least form this awareness.
