Legibility in the Lecture Hall.
Bartlett, Albert A.; Thomason, Michael A.
Physics Teacher, v21 n8 p531 Nov 1983
Recommends black chalkboards, wet-washed before every lecture and advocates the use of Railroad Crayon chalk because its softness and larger size result in a wide high-intensity line. The resulting contrast improves the visibility of material written on chalkboards. (Source for the chalk is provided.) (JM)
