Describes a project that enables students to emulate a scientist in the classroom setting through collaboration on research projects, use of research literature, and communication with scientific peers. Student groups focus on investigations of the cellular and molecular aspects of a disease. (DDR)

Describes two investigative labs that use live plants to illustrate important biological principles, include quantitative analysis, and require very little equipment. Each lab is adaptable to a variety of class sizes, course contents, and student backgrounds. Topics include the evolution of flower size in Mimulus and pollination of Brassicas. (DDR)

Describes an experiment to demonstrate a simple method for measuring fungus growth by monitoring the effect of temperature on the growth of Trichoderma viride. Among the advantages that this experimental model provides is introducing students to the importance of using the computer as a scientific tool for analyzing and presenting data. (AIM)

Data sharing among multiple lab sections increases statistical power of data analyses and informs student-generated hypotheses. We describe how to collect, organize, and manage data to support replicate and rolling inquiry models, with three illustrative examples of activities from a population-level biology course for science majors. (Contains 1…

The study investigated specific student behavior in introductory and advanced college laboratories in botany, chemistry, geology, physics, and zoology. Behaviors were observed, described, and classified with no effort made to induce change, detail underlying conditions, or identify correlates. (Author/RE)

Investigations that facilitate experimental design, the concept of replication, data analysis, and other aspects of scientific study are described. A list of materials, the recommended plants, and the directions for building the hydroponics unit are included. (KR)
