Described and evaluated is a new wave form analyzer and an electrolysis apparatus. (SL)

Describes a general chemistry course taught by the Keller Plan, or personalized system of instruction, at a university with a large minority enrollment. Evaluation shows that students feel that they are learning more and getting higher grades. (MLH)

Described is the history of experimental biology in American universities during the period 1870 to 1910. A discussion of the causes for the use and success of experimental biology in America is included. (SL)

Describes the construction and application of two new types of detectors that use the discharge provoked in a gas by the passage of a charged particle as the means of detection. (MLH)

Examines the mathematics of the exponential function and some examples of its application in analyzing inflation. (MLH)

Describes an elementary one-semester course in the physics of sound and light with an emphasis on applications in art, music, photography, and theater. (MLH)

Includes five brief articles on: solar-heating demonstration equipment, mercury or sodium vapor lamp spectroscopy, an apparatus for simulating variable stars, a voltage-to-frequency converter, and an introductory absorption experiment for low-energy beta particles. (MLH)

The National Science Foundation has a long supported the use of "Wisconsin Fast Plants" (rapid cycling "B. rapa") in the teaching of Biology (K-12). I believe that the opportunity is at hand for biologists to significantly extend past efforts made by our colleagues at the K-12 level to higher education. Biology faculty can realize the many…

This study explored how science and scientists were produced and reproduced within the setting of a university biology department. Building upon recent work in anthropology of education and feminist science studies, the study examined the reflexive questions of whether increased women's representation in science changes science practice and…

The authors advocate that students frequently lack fundamental numerical literacy on the order of millions or billions, and that this comprehension is critical to grasping key evolutionary concepts related to the geologic time scale, the origin and diversification of life on earth, and other concepts such as the national debt, human population…

This paper describes a theoretical framework for the investigation of some specific types of visual learning difficulties commonly experienced by biology undergraduates. The framework was developed based on the findings of three simple qualitative pilot studies. A variety of neurological, cognitive and cultural mechanisms can influence what humans…

Studied the effectiveness of using small individual molecular model kits to enhance achievement by university freshmen in a chemistry course. Concluded that students with experience of visualizing chemical concepts shifted their methods of learning from mere rote recall to critical reasoning. (CC)

Discusses the theory and experimental procedures for using Young's eriometer to determine the diameters of blood corpuscles, lycopodium powder, and wool fibers. (CC)

Describes a college microbiology course in which traditional lectures were abandoned in favor of guided learning objectives and student initiative. A statistical analysis of the data indicates that student achievement on the nonlecture-plus-lab system was not so great as on the traditional lecture-plus-lab course. (JR)

Discusses the properties desirable in a natural area to be used as a teaching tool in college courses such as general biology, botany, zoology, entomology, and ecology. Describes the use of a natural area at Harford Community College, Maryland, and outlines the community involvement in planning and utilizing the area. (JR)
