This dissertation reports the results of a one-year pilot study conducted to determine the feasibility of a small group-discovery method with a class of college freshmen studying calculus. The class consisted of twelve volunteer students who had A or B grades in their high school mathematics courses. The pilot class scored slightly better on a…

This study compares the relative effectiveness of a meaningful verbal approach and a guided discovery approach to learning selected science principles at the seventh and ninth grade levels. A total of 72 subjects were randomly selected from the seventh and ninth grades of Arnold Junior High School and Cleveland Senior High School and made up two…

Reported are the results of a study designed to test the effects of a programed unit in fundamentals of logic on the ability of college capable junior high school students to verbalize mathematical generalizations. The independent variables were the presence or absence of study of the logic unit, and ability level being college capable (I.Q.…

Some ways in which exploratory activities of the preschool child involve science concepts are described. The role of adults knowledgeable about both science and child development is stressed. Emphasis is placed on hands-on experiences. (EB)
