Photography can be a useful tool for teaching biology at both the macroscopic and the microscopic levels of organization. While more complex, taking photographs of microscopic specimens is a procedure that can be performed with all students. In this article, the authors outline a general approach that can be followed to develop a specific protocol…

Recrystallization of benzoic acid is an excellent way to remove insoluble impurities. In a traditional organic laboratory experiment, insoluble impurities are removed through the recrystallization of benzoic acid utilizing water as the recrystallization solvent. It was our goal to develop a peer-led, problem-solving organic laboratory exercise…

A new project-based lab was developed for third year undergraduate chemistry students based on real world applications. The experience suggests that the total analytical procedure (TAP) project offers a stimulating alternative for delivering science skills and developing a greater interest for analytical chemistry and environmental sciences and…

It is challenging for biomedical engineering programs to incorporate an indepth study of the systemic interdependence of cells, tissues, and organs into the rigorous mathematical curriculum that is the cornerstone of engineering education. To be sure, many biomedical engineering programs require their students to enroll in anatomy and physiology…

Describes a training program for teaching assistants who presented laboratory instruction in a biology course and attended weekly seminars, in addition to being observed and video-taped while teaching. (LS)

Describes an exercise that teaches Mendelian inheritance using human traits which students find exciting and relevant. (LS)

An experimental psychology course which analyzes the broad probability of operant conditioning is described. (DE)

A course in teaching research methods in an experimental child psychology course is described. (DE)

Describes a method in which the effect of impurity ions in the dielectric is taken into account in the operation of the Kerr cell. (Author/CP)

Describes a course designed to contribute directly to the teacher's ability to teach chemistry at the high school level with particular emphasis on planning and running a laboratory. Outlines the topics and occurrences in the course week by week. (GS)

By using a computer to simulate experimental situations, engineering laboratory courses can provide more ambitious experiments as well as experiments demanding more calculations. (SD)

Describes how to adapt physical science laboratories which depend on visual data input for blind students. Gives instructions for graph construction, use of the tape recorder, solving mathematical problems with a Braille abacus and other suggestions for physical science labs. (BR)

Describes a simple method for extracting bacterial DNA for use in laboratory investigations to study genetic transformation in bacteria. (BR)
