The classroom refers to a general, widely found, class of learning environments with the following characteristics:
- A single (primary) explainer and multiple (usually ,at least three) learners, all within the same room (i.e., in geographical proximity), with the explainer usually at the front of the room and having access to tools such as chalkboards or display screens for showing slides or computer screens.
- The explainer is generally considered the authority figure of the classroom. The explainer controls the main action in the classroom (the use of the chalkboards or display screens, as well as all loud conversation), though individual pieces of it may be delegated to different learners.
- With respect to the material being covered, learners are expected to have sufficiently similar levels of background knowledge to make the classroom setting feasible; in practice, there may be significant differences between learners' background.
