Smaller, faster computers, bullet-proof t-shirts, and itty-bitty robots--such are the promises of nanotechnology and the cylinder-shaped collection of carbon molecules known as nanotubes. But for these exciting ideas to become realities, scientists must understand how these miracle molecules perform under all sorts of conditions. This brief…

Graduate Teaching Assistants (GTAs) are frequently asked to lead discussion groups. These groups generally take the form of tutorials, review sessions, or problem-based learning classes. In their preparation, what to teach is often emphasized over how to teach. The primary intent of this article is to provide a few simple teaching strategies for…

Pedagogy, the art and science of teaching, should be the driving force behind the design of any teaching facility. What is taught and how it is taught should determine the size, type, and configuration of educational space. The statement seems obvious, but often miscommunication and ill-considered compromises can divert a capital project from an…

This article describes a field biology course specifically designed for students planning to teach in the elementary or middle-level grades. The fundamental goal of the course is to improve students' science literacy and enhance their ability to apply science concepts in the classroom.

Genomics profoundly affects society, because genome sequence information is widely used in such areas as genetic testing, genomic medicine/vaccine development, and so forth. Therefore, a responsibility to modernize science curricula exists for "post-genome era" educators. At my university, we developed a BS biotechnology program within a liberal…

Instructors used an electronic response system to enhance student-centered learning in large and small college biology classes. The system worked well to engage students in learning the subject matter and to assess their prior knowledge and misconceptions. It provided useful feedback to students as well as instructors. Problems encountered…

A survey of 55 colleges showed that the learning environments in introductory science courses are not always as supportive as they should be. Furthermore, most innovative teaching techniques, as recommended by the National Science Education Standards (NRC 1996), are used only occasionally, despite students viewing them as helpful.

This brief article consists of the author's personal observations after attending the Society of College Science Teachers/National Science Teachers Association national convention. The author focuses particularly on the need to make an effort to encourage more graduate students to attend this type of conference, citing the importance of…

The hallmark of an open-ended case study is the possibility of multiple outcomes to the problem at hand. This adds to the realism, provokes higher-order thought, and attracts many instructors to case analysis. Yet, there are circumstances in which a closed-ended approach, having a single correct answer, may be preferred. In this article, the…

The Medicinal Plants of the Southwest summer workshop is an inquiry-based learning approach to increase interest and skills in biomedical research. Working in teams, Hispanic and Native American students discover the chemical and biological basis for the medicinal activity of regional plants used by healers. (Contains 4 tables and 1 figure.)

We describe a team-taught course entitled Chaos in Science and Literature. Our course goals were to place science in a nontechnological context, emphasizing its intellectual and cultural aspects, and to provide a forum for the exchange of ideas between "scientists" and "humanists," with the authors serving as role models. (Contains 4 figures.)

Exposing students to content outside of the classroom encourages them to take control of their learning. This article describes three methods for redesigning courses to create more class time for the development of higher-order skills. The combination of in-and out-of-class activities improves student learning without sacrificing course content.…

The effectiveness of an issues-based approach to nonmajors biology was investigated. The integration of online critical-thinking exercises and in-class discussions of science-related issues did not improve exam scores. However, students did indicate that the discussions enhanced their appreciation of science and stimulated them to think more…

A serendipitous finding involving static magnetic fields can be used to design experiments suitable for both science and nonscience majors. It has been reported that organisms respond differently to high-gauss magnetic fields generated by north poles than they do to those generated by south poles. Experimental tests of this hypothesis are ideal…

A successful undergraduate research experience depends on a good mentor/ teacher. Surveys, interviews, and focus group discussions reveal that students and their mentors agree that research learning is very different from classroom learning. They do however disagree about some of the dynamics and priorities of the mentoring relationship. (Contains…
