Plastics: Mold Design And Fabrication, Duane H. Rippe

Graduate Research Papers

Students have often asked if additional molds were available which would make different objects other than golf tees. Literature provided with the injection molder described several methods of mold construction which could be fabricated in the school shop. The writer considered the possibility of making another mold, however, a time factor and limited experience prohibited construction.

The problem seemed to be appropriate for the Projects Course 33:270 at the University of Northern Iowa. The course and research involved would assimilate the needed information to construct a mold and to teach plastic injection mold construction more effectively.

An Evaluation Of Demonstrations On Inductor Theory, Boyd Warner Wasson

Dissertations and Theses @ UNI

The writer sought an improved approach for teaching theory of electronics to high school students. This approach was intended to require less expense and time needed to provide classroom instruction on electrical theory.

The purpose of this study were to:

(1) Prepare a number of demonstrations to illustrate phenomena associated with coils or inductors and their use in practical electronics.

(2) Prepare equipment and gather parts needed to perform demonstrations. Ease of construction and economy were important considerations.

(3) Evaluate the effectiveness of the demonstrations on student comprehension and the ability to apply information taught.
