Describes an organic-biological experiment that illustrates an important chemical commercial process and the use of microorganisms as chemical reagents. (MLH)

Describes an experiment in which the iodonation of aniline reaction is shown to undergo catalysis in solution of sodium lauryl sulfate which forms micelles with negatively charged pseudo surfaces. (MLH)

Describes an advanced undergraduate experiment in which the stepwise stability constants of hi(II)-cysteine chelate are determined. (MLH)

Describes an experiment in which ph values serve as a basis for separating the acidic aspirin from phenacetin and caffeine on an ion-exchange column. (MLH)

Described is a physics experiment in which small bits of metal on a water surface will move towards, and away from an electrostatically charged rod. The explanation for the motion of the metal bits deals with their shape and the electrical force on the water surface. (SL)

Describes an advanced undergraduate laboratory experiment for studying thermionic emission. The cathode of a type 922 photodiode is used as an emitter over a temperature range from room temperature to 80 degrees centigrade; the thermionic emission current varies by a factor of 3000 over this temperature range. (MLH)

The agencies listed in this document are amending the Federal Policy for the Protection of Human Subjects, which was published in the Federal Register on June 18, 1991, to change all references to the Office for Protection from Research Risks (OPRR) to the Office for Human Research Protections (OHRP); revise the footnote found at the end of…

This report contains five action research papers in science education. Papers include: (1) "Does Classroom Size in an Industrial Technology Laboratory Affect Grades and Success in Class?" (Chad Bruns); (2) "The Effects of Project Based Learning on Students' Engagement, Independence, and Interest in Physical Geology Class" (Jill…

Universities and colleges are a critical component of the nation's research system. The condition and availability of research facilities at these institutions influence the work of current and future scientists. Recognizing the need for information on the amount and quality of scientific and engineering (S&E) research space, Congress mandated…

Noting that at Saint Mary's University (where the authors teach) the issue of spirituality is in the forefront of education and is seamlessly woven into required courses throughout four years of college in an attempt to "enhance students' spiritual and personal lives," this paper positions writing centers as a place for student inquiries…

This paper describes attempts to bring writing center planning for a global, multicultural world to Rivier College, New Hampshire, a small, predominantly white, Catholic college. It explains how the writing center has been instrumental in leading this planning process. The process began with education on four broad issues regarding diversity and…

This series of issues of a newsletter called "The Dangling Modifier" begins with Volume 1, Number 1 (Fall 1994) and concludes with Volume 9, Number 2 (2003). The newsletter is subtitled "A National Newsletter by and for Peer Tutors in Writing" for the majority of the issues--the last issue changes the subtitle to "An…

For one graduate student administrator at the University of Wisconsin-Milwaukee, some examples of what she considers to be teacher apathy are: complaints by the writing laboratory director that a teaching assistant (TA) was not using the recommended readings but a Nietzsche essay to have his students explore a contemporary political issue, and…

Based on concern for the equality of learning opportunities in laboratory work, this study aims to explore the meanings of learning opportunities from a theoretical literature review, and to investigate the distributions of learning opportunities from practical laboratory instruction. Considering both the nature of science activities and the…

For the purposes of this paper, proofreading will be defined as the final step of revising a paper. The paper describes what one writing lab, the Writing Center at the University of Connecticut, does to provide students with one-to-one help with their writing. It explains that services in the center include individual tutorials, a grammar hotline,…
