Drawing for Teachers of Solid Geometry

Abstract

The College Entrance Examination Board in its Document No. 108, containing a definition of the requirements in geometry adopted by the board on April 21, 1923, has included an appendix on drawing which opens with the following paragraphs:“An important aid to the visualization of space figures is the ability to draw these figures on paper. The pupil should be trained to make neat free-hand drawings, inserting whatever construction lines are needed and supplementing the representation of the space figure by independent drawings of plane sections, whenever such contribute to clearness. Ruler and compasses may often be used with advantage, but no technical knowledge of descriptive geometry or the niceties of mechanical drawing forms any part of the requirement. The use of ruler and compasses in the examination is permitted and to a moderate degree, desirable but it is not prescribed.
