This article investigates three teachers' conceptions and use of inquiry-based instructional strategies throughout a professional development program. The professional development program consisted of a 2-week summer inquiry institute and research experience in university scientists' laboratories, as well as three academic year workshops. Insights…

In this paper we describe the recent changes to the curriculum of the second year practical laboratory course in the School of Physics and Astronomy at the University of Nottingham. In particular, we describe how Matlab has been implemented as a teaching tool and discuss both its pedagogical advantages and disadvantages in teaching undergraduate…

Though deceptively simple to teach, chromatography presents many nuances and complex interactions that challenge both student and instructor. Time and instrumentation provide major obstacles to a thorough examination of these details in the laboratory. Modern chromatographic method-development software provides an opportunity to overcome this,…

The Microelectronics WebLab at MIT allows students to do actual (not simulated) laboratory research on state-of-the art equipment through the Internet. This study assesses the use of WebLab in a junior-level course on microelectronic devices and circuits in 2004-05 and 2005-06. In quantitative surveys and qualitative interviews, students and…

The study aimed to correlate the performance of Pohnpei Campus freshman students in the College of Micronesia-Federated States of Micronesia during the fall semester 2009 to students' socio-demographic characteristics, parents'/guardians' socio-demographic characteristics, and school characteristics. The Student Survey Questionnaire gathered data…

America's advantage has historically been its people's creativity, flexibility and entrepreneurship. But just as painters need to be proficient in technique and theory to produce great masterpieces, the next generation of Americans will likely require a solid grounding in mathematics and science for their creativity to be maximized in a world…

Although researchers in higher education propose alternatives to traditional approaches to assessment, traditional methods are commonly used in college or university science courses. The purpose of this study was to explore the feasibility and validity of Prospective Science Teachers' (PSTs) concept maps as authentic assessment tools in a…

"Keeping Pace" has several goals. First, it strives to add to the body of knowledge about online education policy and practice and make recommendations for advances. Second, it serves as a reference source for information about programs and policies across the country, both for policymakers and practitioners who are new to online…

The commercial simulator Aspen Chromatography was used in the computer laboratory of a dual-level course. The lab assignments used a cookbook approach to teach basic simulator operation and open-ended exploration to understand adsorption. The students learned theory better than in previous years despite having less lecture time. Students agreed…

Uniform illumination levels in the classroom and focused brightness on the "teaching wall" made good sense for students in Henry Ford's era. If you were training to take your place on the assembly line, you needed to focus on the work at hand and ahead to your supervisor, but the future no longer belongs to students who look only straight ahead.…

In the applications of instrumental analysis lessons, advanced instruments with the needed experiments are needed. During the lessons it is a fact that the more experiments are performed, the more learning will be. For this reason, experiments that do not last long and should be performed with more simple instruments and that increase students"…

In undergraduate engineering labs, lab reports are routinely copied. By ignoring this form of plagiarism, teaching assistants and lab technicians neglect their role responsibility. By designing courses that facilitate it, however inadvertently, professors neglect their causal responsibility. Using the case of one university, we show via interviews…

An experiment related to the measurement of fluorescence lifetime for an undergraduate instrumental analysis or physical chemistry laboratory that highlights relative rates of electronic transitions in molecules and introduces students to data collection of a pulsed signal is illustrated. The experiment of the long fluorescence lifetime of…

This article presents the methodology and results for a simple approach to the measurement of the transition temperature of a superconducting material, in a pre-university laboratory session, using readily available apparatus (and some liquid nitrogen).

The author discusses mentoring and training strategies that enhance adjunct faculty members' teaching effectiveness in undergraduate science laboratories and foster a sense of common enterprise within the institutional environment. These strategies include the preparation of an "Adjunct Faculty Handbook", mentoring and peer-support programs, and…
