Hypotheses of population genetics are derived and tested by students in the introductory genetics laboratory classroom as they explore the effects of biotic variables (physical traits of fruit flies) and abiotic variables (island size and distance) on fruit fly populations. In addition to this hypothesis-driven experiment, the development of…

For distance-education students, the requirement for a laboratory course can present a significant hurdle to completing degree requirements. To better serve these nontraditional students, the authors developed a distance version of the laboratory course to provide a hands-on experience similar to that of on-campus students. In order to make the…

Explains an online introductory biology course that applies the inquiry approach to hands-on laboratories. Evaluates learning objectives such as the knowledge of biology, reasoning, attitudes, and graphing skills. (YDS)

Describes the use of simple projects to help freshmen-level chemistry students develop chemical knowledge and an aptitude for the research process. These projects pose a new problem to students without presenting a detailed experimental procedure. Guiding questions help students design their own experiments and stimulate students to think…
