Materials science can be taught by applying organic light-emitting electrochemical thin-film devices and in this method students were allowed to make a light-emitting device by spin coating a thin film containing ruthenium (II) complex ions onto a glass slide. Through this laboratory method students are provided with the opportunity to learn about…

An exciting laboratory environment is activated by the preparation and novel use of magnetic materials to decontaminate water through adsorption and magnetic removal of metals and organics. This uncomplicated technique is also adaptable to the possible application of adsorbents to numerous other environmental substances.

The Kirby-Bauer method is regularly used to test bacterial susceptibility to antibiotics, and is often employed in the classroom for teaching this concept. In this exercise, additional materials and instructions were given to students for the preparation of garlic extract and loading on blank BBL paper discs. They were further instructed to test…

Following the brewing process from grain to glass, this course uses the biological and chemical principles of brewing to teach science to the nonscience major. Discussion of the scientific aspects of malting, mashing, fermentation, and the making of different beer styles is complemented by laboratory exercises that use scientific methods to…

This paper discusses the development of an interactive approach to teaching and assessing a micro anatomy curriculum in an innovative medical school program. As an alternative to lectures and labs, students are engaged in interactive seminars focused on discussion of clinical and research-based cases matched with normal histology and pathology…

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…

In today's knowledge economy, technology is utilized more than ever to deliver instructional material to the learner. Nonetheless, information may not always be presented in a manner that maximizes the learning experience, resulting in a negative impact on learning outcomes. Drawing on the Task-Technology Fit model, a research framework was…

Traces the inception of laboratory activities in the instruction of physics in American secondary and higher education institutions. In particular, the impact of Edwin Hall on secondary school physics instruction is described. (CP)

A low-cost tensile testing machine was built for testing polymeric films. This apparatus also allows for tear-strength and flexural tests. The experimental results, obtained from common-use materials, selected by the students, such as plastic bags, illustrate important aspects of the mechanical behavior of polymeric materials. Some of the tests…

Twelve science activities involving the common paper food bag and the small plastic food bag are described. (DT)

Describes the use of student projects within a traditional biology laboratory class to incorporate openness, inquiry techniques, and student choice into course teaching. Included is a list of sample investigations. (CC)

This second volume, a compilation of reprints of experimental notes in physics, was prepared by the American Association of Physics Teachers (AAPT) Committee on Apparatus and by the AAPT Executive Office in response to requests received by the Association for a completely new edition. The goal of the Committee was to provide a selection of…

Describes a computer-based instructional model for the physiology laboratory. Attempts to develop an efficient and low-cost system designed to provide dynamic student/machine interaction are discussed. (MA)

Describes the laboratory procedure suitable for an introductory organic chemistry procedure. (CP)

A five-week introductory unit on electricity, structured in a historical perspective provided by the letters of Ben Franklin, is described. (CP)
