An experiment is developed that requires the use of the NMR spectrometer via a NOESY1D experiment to determine the diastereoselectivity in the reduction of alpha-methylbenzoin with various reducing agents. Students must synthesize racemic alpha-hydroxyketones, perform reductions under chelating and non-chelating conditions, and quantitatively…

Ozone is a powerful oxidant and disinfectant, which can be used to clean environment as well as obtain pure drinking water. A series of experiments to produce and test ozone with simple equipment and material are presented.

A microscale experiment in which the simultaneous oxidation of an organic compound and the reduction of a metal ion are photocatalytically performed in an aqueous slurry containing TiO[subscript 2] irradiated with UV light. This experiment can be performed in the laboratory session with simple chemicals and equipments.

This article emphasizes the need for writing centers to give continued attention to online tutoring to achieve writing across curriculum (WAC) goals. The article offers a literature review covering the history and state of online tutoring and its relation to the WAC movement and writing fellows programs. We at Saint Joseph College have found that…

I was interested in whether the inclusion of a service-learning experience would affect students' attitudes and values about the environment. To investigate this question, I incorporated a service-learning project into the laboratory portion of one of the two sections of my non-majors biology course, and kept the lecture portions of the course…

Anatomy education in Pakistan is facing many of the same challenges as in other parts of the world. Roughly, a decade ago, all medical and dental colleges in Pakistan emphasized anatomy as a core basic discipline within a traditional medical science curriculum. Now institutions are adopting problem based learning (PBL) teaching philosophies, and…

Peer teaching has been recognized as a valuable and effective approach for learning and has been incorporated into medical, dental, and healthcare courses using a variety of approaches. The success of peer teaching is thought to be related to the ability of peer tutors and tutees to communicate more effectively, thereby improving the learning…

The laboratory has long been an important part of the undergraduate science experience. This paper reports on a qualitative, grounded theory study on students' perceptions of the purpose of the laboratory. Thirteen undergraduate chemistry students were interviewed about their experiences in the science laboratory to provide data on students'…

Remote laboratories are technologies that aim to increase the effectiveness of educational programs. European Remote Radio Laboratory (ERRL) is an e-learning project for students, teachers and technicians who will use very important devices of a radio frequency laboratory remotely. As a solution we have developed an e-learning system which aims to…

The polygraph (lie detector) may be an ideal vehicle for converting aspects of a physiology course into an interdisciplinary course, enabling discussion of interrelationships between science, technology and society (STS) and social dilemmas arising from technological developments. The authors present a way of incorporating the polygraph into a…

Social order is possible only if individuals forgo the narrow pursuit of self-interest for the greater good. For over a century, social scientists have argued that sympathy mitigates self-interest and recent empirical work supports this claim. Much less is known about why actors experience sympathy in the first place, particularly in fleeting…

This study assessed the effectiveness of an innovative science course for improving prospective elementary teachers' perceptions of laboratory learning environments and attitudes towards science. The sample consisted of 27 classes with 525 female students in a large urban university. Changing students' ideas about science laboratory teaching and…

Since Robert Millikan discovered the quantization of electric charge and measured its fundamental value over 90 years ago, his oil-drop experiment has become essential in physics laboratory classes at both the high school and college level. As physics instructors, however, many of us have used the traditional setup and experienced the tedium of…

Engineering education in India has witnessed a major change over the past few years. Substantial increase in the demand for high-quality education has led to the adoption of Information and Communication Technologies for extending the outreach of education. This paper presents a review of some of these technology-enhanced initiatives already taken…

This paper describes the effects of learning support on simulation-based learning in three learning models: experiment prompting, a hypothesis menu, and step guidance. A simulation learning system was implemented based on these three models, and the differences between simulation-based learning and traditional laboratory learning were explored in…
