A Laboratory-Centered General Chemistry Course For College Freshmen, Alexander Vavoulis

University of the Pacific Theses and Dissertations

In order to give the laboratory-centered course a trial run and to compare it with a lecture-centered course it seemed necessary to the author that both courses should be taught and compared. The latter gave rise to the following hypotheses:

1. Students in a laboratory-centered general chemistry course show more favorable attitudes toward chemistry than do students in a lecture-centered course.
2. Students in a laboratory-centered course show as good a subject-matter mastery as students in a lecture-centered course.

A New Approach To General Chemistry Laboratory In College (With) A Laboratory Manual For General Chemistry, Constantine G. Vlassis

University of the Pacific Theses and Dissertations

Statement of the problem. This study was carried out to determine: (1) what advantages a laboratory-centered general chemistry course might have over the conventional laboratory course, and (2) whether improved understanding of laboratory work leads to better learning of chemistry. The four following questions were raised in connection with the study or this problem:

1. What is the need for a laboratory-centered course?
2. What has been done in the past to meet this need?
3. Can students learn chemistry more effectively in a laboratory-centered course as compared to the conventional course?
4. Is a laboratory-centered course to be preferred over the conventional course …

Experimental And Observational Geometry, Albert D. Field

University of the Pacific Theses and Dissertations

Geometry has the distinction of being one of the oldest subjects given in the high-school.

Its subject-matter was formulated and organized by the Greeks into a fine system of thought before the time of Christ. Since leaving the hands of the Greeks, geometry has received only a few minor changes, and these largely in recent years.

Heretofore, the study of geometry has been made almost entirely dependent upon memory and reasoning. Geometricians have been slow in adopting the laboratory and observational methods.

This thesis has been written to encourage the student in his work of observing geometrical forms, and in …
