Measurable Outcomes of Two Methods of Teaching Experimental Geometry
To determine scientifically how the lecture demonstration method compares with the individual-laboratory method of teaching, when geometric material is presented as a laboratory science, is the problem. The pro cedure consisted of forming two parallel groups of pupils which were nearly alike in mental equipment as measured by those factors which were considered likely deter minants for successful achievement in school subjects, and which were about at the same point on the learning curve in terms of achievement in geometry. The group which was taught by the lecture-demonstration method was designated the control group and the one taught by the individual-laboratory method was designated the experimental group.
