A simple, reliable, and cost-effective experiment is presented in which students synthesized citrate-capped gold nanoparticles (GNPs), functionalized them with poly(ethylene glycol) (PEG), and transferred the PEG-GNPs from water to the organic phase dichloromethane. The experiment introduces students to nanotechnology with foci on important…

Emerging interest in genomics in the scientific community prompted biologists at James Madison University to create two courses at different levels to modernize the biology curriculum. The courses are hybrids of classroom and laboratory experiences. An upper level class uses raw sequence of a genome (plasmid or virus) as the subject on which to…

This article describes how a collaborative class strategy and an introductory activity were used to develop students' thinking about business and management communication. The article focuses on teachers who want to integrate critical perspectives about business communication into their classes. A course ethos, learning groups, and an introductory…

In the online environment, students and instructors are virtually, but not physically, present in the same environment. In the online environment, technology mediates learning: it mediates communications and information transfer between the student and the instructor, between the student and the content, and among the students. Critics fear that…

Active-learning techniques have been advocated as a means to promote student engagement in lower-division biology courses. In this case study, mini-lectures in combination with active-learning activities were evaluated as strategies to promote a culture of learning and participation in a required botany course. These activities were designed to…

Ideally, college classes are small. Kilgore and Cook (2007) observed that large class size can be an obstacle to good teaching. However, there is financial and human resource value in delivering quality course content in large lectures. Consequently, large lecture classes are a fundamental part of the undergraduate student experience at many…

This study investigated the possible connection between effective laboratory activities and student performance on lecture exams. In a traditional undergraduate organic chemistry course for non-science majors, students could predict the products of organic reactions, but struggled to provide reaction mechanisms for those same reactions, despite…

A peer mentoring program was added to an introductory chemistry course at a large university. The introductory chemistry course prepares students with little or no previous chemistry background to enter the mainstream general chemistry sequence and is part lecture and part small-group problem-solving. Faculty instructors are responsible for the…

A guided-inquiry exercise conducted in both the lecture and laboratory components of a college introductory chemistry course for non-science majors is described. The exercise gave students the opportunity to independently determine the relationship between the temperature of water in an aluminum soda can and the intensity of implosion upon placing…

Much of modern mathematical research requires a serious level of commitment and ability on the part of the researcher and, as a natural consequence, precludes any real involvement by undergraduate mathematicians. However, to put it crudely, Computer Algebra Systems, can make experts of us all. With the use of such systems even the average…

Discussed is a series of lectures designed to illustrate the use of general organic chemical principles in molecular biology, introduce current research in interdisciplinary areas to the beginner, increase interest in organic chemistry, and bridge the gap between traditional organic chemistry, biology, and the consumer. An outline is presented.…

Discusses an analysis of 10 common introductory psychology textbooks. Argues that the books tend to present psychology as tedious, even silly, and as a canned, multimedia, self-teaching program. Concludes that replacing textbooks with lectures based on the instructor's personal knowledge and experience would improve the teaching of psychology. (SG)

Describes a college-level course in health psychology. Recommends a course divided between lectures and a class-designed research project. Reports that course evaluations by the students indicated that the students enjoyed the course design and assignments. (CFR)

Discusses methods of personalizing the large introductory college psychology class. Contrasts active learning by students with lecturing by professors. Suggests that separating the large class into smaller units can facilitate active learning. Argues that active learning also can be promoted in the large class setting. (SG)

Describes a method for promoting student interest and involvement in an undergraduate marriage and family course. Supplements lectures with problem-solving sessions for small groups. Uses session outcomes to encourage critical evaluation by the class. Combines the traditional scholarly approach with an interactive personal involvement. (NL)
