Dissertations and Theses @ UNI

The use of inductive or inquiry techniques in the teaching of science has been emphasized. A possible technological aid to the inquiry process is the electronic computer. A review of the literature in this area led to the development of two program processors, one to produce simulated experiments, the other to generate problems for student use.

The first processor, SIM/G, can be used to produce tables or charts. Five sample programs were prepared to illustrate the use of the SIM/G processor. Directions for use of the processor have been given. Documentation has included both a complete verbal explanation and a …
