Levels of tolerance refers to the extent to which a teacher can tolerate different noise levels, activities, and pupil behavior.

Levels-of-processing framework postulates that memory does not comprise three (3) or even any specific number of separate stores but rather varies along a continuous dimension in terms of depth of encoding.

Levels-of-processing theory of memory is an alternative to the modal view of memory, proposed by Craik and Lockhart, that postulates that memory depends not on a particular memory store but on the initial processing done to the information at the time of acquisition. "Shallow" or "superficial" levels of processing, as in the processing at the level of visual shape or acoustic sound are thought to lead to less retention than "deeper" levels of processing such as in processing done on the meaning of the information.
