The purpose of this thesis is to conduct a study of the elements which cause difficulty in the reading of maps, charts, and graphs and the effect which the elements have on programming the reading of maps, charts, and graphs for instruction. The experiment was made to determine (1) if work of this kind is profitable for students and (2) which elements cause the greatest difficulty for students: (a) types of graphic aids used; (b) the numbers of aids used: (c) the depth of thought required to answer the questions.
