Abstract

Since 1926, various aspects of the general botany teaching program at Iowa State College have been studied. Victor (1933) and Dietz (1935) described studies dealing with teaching procedures and techniques and evaluation practices. Kreutzer (1935) and Dietz and Gould (1939) reported on certain phases of the testing program, particularly the practice of grouping students enrolled in Botany 101 according to scores made on pretests. Bragonier (1941) described the methods used in constructing and evaluating the pretests. The value of grouping the students for instructional purposes is generally acknowledged within the botany department, however, the means by which the students are grouped is not as well accepted and, consequently, was chosen as the subject for this study.
