What is it about small groups that make them so powerful? The answer is straightforward: Groups tend to solve problems better than even the brightest individuals because "many hands make light work," and "two heads are better than one." This is especially true when the groups are diverse and individuals act somewhat independently. In this month's…

Case study teaching had a long tradition in law and business before it made the jump to medical school education in the form of Problem-Based Learning (PBL) in the 1970s. Today, both the University of Delaware's Clearinghouse and the University of Buffalo's National Center for Case Study Teaching in Science (NCCSTS) have hundreds of cases and…

In this problem-based learning activity designed for nonscience majors, students assume the roles of scientists working for a public relations firm. Teams of students design communication products illustrating links between climate change and pollen allergies. Students develop a variety of process skills critical to scientists, including working…

Presents a scenario about a planet that uses problem based learning to teach evolution and ecology to freshman biology students. (YDS)

Presents a case study to teach about the relationship between sinkhole development and groundwater levels in Orlando, Florida. Discusses the relationship between groundwater levels and sinkhole formation in a karst terrane. Includes discussion questions. (YDS)

Uses a problem-based teaching approach to teach about the geological origins of the Galapagos Islands, colonization, species formation, and threats to biodiversity. Discusses finches, tortoises, and sea cucumbers and provides instructions for student discussions. (YDS)

Explains the steps necessary to write a case study. Illustrates the development of a case study for a freshman Evolutionary Biology class. (YDS)

Presents a rear-end car accident scenario to teach about forces and kinetic energy in a problem-based learning format. Includes four parts: (1) "A Bad Day for Sandy Dayton"; (2) "The Emergency Room"; (3) "The Facts of the Case"; and (4) "Judgement Day". Discusses the major issues of the questions, introduces scientific concepts, and initiates…

Reviews the origin of problem based learning (PBL) and variations of PBL. Suggests that PBL is simply one way of case study learning. (Author/KHR)

Describes a project that applies problem based inquiry learning units to an introductory chemistry laboratory curriculum. Uses web technologies to support instruction. (Contains 25 references.) (YDS)

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…

Describes a problem-based human biology course for undergraduate nonscience majors. Discusses the nature of problem-based learning, effectiveness of problem-based learning in a nonmajors' science course, course development, and implications. Contains 14 references. (JRH)

Presents a chemistry report on methamphetamine synthesis downloaded from the Internet and asks students to point out errors and answer questions about the text. Discusses the methods of methamphetamine synthesis and major issues in writing a case study. (YDS)

Presents a classroom activity in which students identify the possible ways of reducing NOx emissions to reduce ground-level ozone. (YDS)

In this article, the author discusses how to properly implement a case study. Specifically, he discusses how much information should be put into a case study. The author suggests to clearly know what the goals of a case study are before starting to write it. He states that in most cases, the straightforward approach without contradictions poses…
