One aim of physics laboratory instruction is to help students connect theory to practice. So experiments are often chosen in order to "demonstrate" specific concepts. Furthermore, students are expected to approach phenomena in a scientific way, that is, they should develop a hypothesis and plan their experiments accordingly. Although it is usually…

Physics labwork has for a long time now been an important part of academic physics education. But demands on physics education have changed. However, while seminars and lectures have easily been updated with the latest content, it is much more difficult to modernize labwork courses: mere changes of content require expensive new equipment, tight…

Details 26 experiments designed for use in secondary or college science classes. Includes activities for physical and biological sciences. Describes procedures, materials, safety, and analyses appropriate for each. (CW)

Reports on the 9th Biennial Conference on Chemical Education sponsored by the American Chemical Society. The conference theme: "Chemistry: Learning, Instructing, Presenting," was addressed by numerous sessions. Highlighted were presentations calling for an increase in process-oriented chemistry teaching, reduction of "science…

Describes a laboratory safety program at the University of Delaware. Includes a history of the program's development, along with standard safety training and inspections now being implemented. Outlines a two-day laboratory safety course given to all graduate students and staff in chemical engineering. (TW)

Despite efforts to engage students in the traditional lecture environment, faculty in Georgia Southern University's Physics Department became dissatisfied with lecture as the primary means of instruction. During the fall semester of 2006, our department began adapting the studio model to suit the needs of introductory calculus-based physics…

The purpose of the U.S. Department of Education's online newsletter "The Education Innovator" is to promote innovative practices in education; to offer features on promising programs and practices; to provide information on innovative research, schools, policies, and trends; and to keep readers informed of key Department priorities and…

During the past three years we have been designing and implementing a technology enhanced urban ecology program using geographic information systems (GIS) coupled with technology. Our initial work focused on professional development for in-service teachers and implementation in K-12 classrooms. However, upon reflection and analysis of the…

Clickers were used for real-time data collection in two introductory biology laboratory courses so that students could perform statistical analysis on large data sets. Student attitudes toward this use of clickers were surveyed and students were administered a pre- and posttest on statistical content. Capture of large data sets allowed instructors…

This study compares characteristics of fluency in student audio journals recorded in a laboratory setting with those recorded using mobile audio devices. Forty graduate students enrolled in four oral communication courses at an American university recorded weekly audio journals for a 10-week term. Students chose the environment in which they…

The reproducibility of experimental outcomes depends on consistent control of independent variables. In food-maintained operant performance, it is of utmost importance that the quantity of food delivered is reliable. To that end, some commercial food pellet dispensers have add-on attachments to sense the delivery of pellets. Not all companies,…

An inexpensive and automated method for presentation of olfactory or tactile stimuli in a two-choice task for rats was implemented with the use of a computer-controlled bidirectional motor. The motor rotated a disk that presented two stimuli of different texture for tactile discrimination, or different odor for olfactory discrimination. Because…

Does the physical environment improve an institution's recruitment efforts? More specifically, could a facility such as a laboratory of the future attract the best and the brightest students and faculty? This issue has been the subject of at least two studies--first, "How Do Students Choose a College?" in 1986 by the Carnegie Foundation for the…

A take-home experiment kit has been developed to reinforce the concepts in a first year physics course that both on and off campus students from a variety of educational backgrounds can successfully use. The kit is inexpensive and is composed of easy to obtain items. The experiments conducted with the kit are directed experiments that require…

In this paper, we discuss a simple apparatus and accompanying class activity that we have developed to illustrate the Biot-Savart law. Since students in introductory electricity and magnetism courses often find this law a mathematical mystery, we feel that a simple experiment such as this will provide the students a better understanding of the…
