Presents Part II of a description of a computer-oriented course on process control which has been offered at the University of Wisconsin for undergraduate students. Lecture topics and laboratory experiments are also included. (HM)

A modification of the Ames test for detecting carcinogens and mutagens using a strain of bacteria is described. A suggestion is given for checking the correctness of procedures by using particular hair dyes which have been shown to be mutogenic. (Author/SA)

Urges the use of plastinated specimens as an alternative to traditional dissection in biology classrooms. Suggests that plastinated biological specimens heighten student interest and enhance teaching. Interview responses of students, teachers, and administrators to the use of plastinated specimens in selected high schools were found to be very…

Introduces an alternative method to determine the mechanics of a moving object that uses computer vision algorithms with a charge-coupled device (CCD) camera as a recording device. Presents two experiments, pendulum motion and terminal velocity, to compare results of the alternative and conventional methods. (YDS)

Describes a technique for using lecture-laboratory facilities and faculty office facilities to provide students a site for intensive laboratory exercises. Provides a layout of the lecture-laboratory facilities and energy systems of the facilities. Presents an instructional example on the concept of the natural frequency of single-degree-of-freedom…

The purpose of this study was to explore how science teachers' epistemological beliefs and teaching goals are related to their use of lab activities. Research questions include: (1) What are the teachers' epistemological beliefs pertaining to lab activities? (2) Why do the science teachers use lab activities? (3) How are the teachers'…

Experimental physics is seen as an essential part of tertiary physics education. Students are supposed to develop practical skills and advance from closed "cookbook" experiments to open experiment and design experiment procedures independently. As a consequence tertiary practical physics courses increase in the level of challenge…

An environment appropriate for activity-oriented science is one that contains sufficient work space, equipment, and materials for students to practice and master the essential elements. This publication was developed to aid Texas school administrators, teachers, and architects to upgrade existing science facilities or plan new ones for…

This is the final report of the evaluation of Project CAUSE, a three year project to improve the laboratory portions of undergraduate physics courses at North Texas State University. The report is divided into six sections. Included in the overview are goals and purposes, the instructional format, and the evaluation plan. Demographic profiles…

Criticizes the way organic chemistry teaching laboratory experiments are approached from the viewpoint of physical chemistry. Compares these experiments to cooking. Stresses that what matters is not the practice of the finger skills of organic chemistry but practice in the style of thinking of organic chemists. (CW)

Indicates that the most dangerous laboratory hazards are the least dramatic ones and that hazardous chemicals are often used in laboratories without proper precautions. Selected sources of information essential for secondary schools and recommendations for safe practices and chemical use statistics from a study of Ohio high schools are given. (DH)

Describes a general purpose microcomputer-based system designed to support small-scale experimentation in the physical sciences in student laboratories. System requirements, teacher reactions, and educational implications are discussed; design criteria are established; and examples are given of the system's application to some simple experiments.…

Explains two approaches to the automatic arrest of a potentiometric titration. (SA)

Discusses the cognitive outcomes of physics laboratory exercises and suggests three types of experiments which should be added to those normally used in physics courses. (HM)

Describes a physics laboratory for college students, in which the students participate in a firsthand noninertial experience. The equipment and problems are described. (SA)
