Comparative Study Of Recitation And Review In Seventh Grade Programmed Geography, Jacob Max Setzer
Comparative Study Of Recitation And Review In Seventh Grade Programmed Geography, Jacob Max Setzer
All Master's Theses
The purpose of this study was to compare the effectiveness of two methods of reinforcing learning gained from programmed material in seventh grade geography classes. The means used for evaluating effectiveness were: (1) comparing retention of the factual knowledge of the material by students exposed to the two methods immediately after completing the material, and, after a time lapse of six months, and (2) comparing the ability of students to transfer their factual knowledge of the material immediately after completing the material, and, after a time lapse of six months.
A Comparison Of Two Textbooks Used In An Eighth Grade Slow Learner Mathematics Program, Douglas Kirk Pederson
A Comparison Of Two Textbooks Used In An Eighth Grade Slow Learner Mathematics Program, Douglas Kirk Pederson
All Master's Theses
It was the purpose of this study to determine whether a textbook designated for use with slow learners was a more suitable teaching device than the regularly assigned textbook. It was the hypothesis of this study that slow learner mathematics students would show no significant differences in achievement due to the utilization of different texts.

Testing An Earth-Science Aid, Florence Black
Iowa Science Teachers Journal
Making a collection is not always considered an erudite use of laboratory time. It has been said that study of rocks, for example, entails a good deal more than discovering that a specific specimen can be assigned a specific name. This is freely admitted to be true, but this writer has discovered that assigning the proper name to a specimen demands a more careful and memorable examination of discriminating details of rock types, for example, and that it leads to a useful familiarity with variations of a single rock type.
