While the great scientists of the past recognized a need for a multidisciplinary approach, today's schools often treat math and science as subjects separate from the rest. This not only creates a disinterest among students, but also a potential learning gap once students reach college and then graduate into the workforce. "Cases on…

Briefly summarizes methods of presenting laboratory information. Suggests that approaching lab problems requires a combination of methods structured into a problem-oriented learning experience. Focuses on the relationship of the gloxysome to the chloroplast and the steps involved in solving the problem. (DDR)

Introduces a chemistry unit, the "Evolving Atom", based on a problem-based learning approach designed for non-science majors. Uses the case method to address memory loss in mice during instruction. (Contains 14 references.) (YDS)

Describes the investigative case-study approach in biology, a variant of problem-based learning. Students develop questions that lend themselves to scientific investigation and develop their own investigative approaches. Contains 16 references. (DDR)

In its use of complex, real-world problems to introduce concepts and motivate learning in an active and cooperative learning environment, problem-based learning is a powerful alternative to the passive lecture in introductory college science. Use of technology and multimedia instruction, focus on large classes, and use of interdisciplinary…
