Explanation

A small class of two to three students is best served by writing on paper (d), since all can gather around one sheet.

A medium class of ten to fifteen students suits a flip chart or white board (a), visible to a small group.

A large class of twenty to twenty-five students suits PowerPoint slides (b) projected for wider viewing.

An extra large class of more than thirty students needs an oval presentation with a display screen (c) for full reach.

The principle is that the display medium must scale with the number of viewers and the viewing distance.

Edgar Dale's Cone of Experience similarly ranks media by how directly and widely they convey content.
