A Commodore-64 microcomputer was used to develop a system which is useful for a variety of teaching laboratory and real time control applications. Hardware and software requirements and examples of experimental work with the system are provided. (JN)

Found that in an introductory biology course at the University of Massachusetts Amherst, adoption of the Data Aggregation Project (free software that allows students in a course to aggregate a large body of data for some particular problem) resulted in an increase in the number of data points students analyzed per semester by a factor of almost…

Describes the construction of an inexpensive light sensor that can be used to measure irradiance in aquatic habitats. Includes a list of tools and materials, details of construction, and usage of the light sensor. (DDR)

It is desirable that the undergraduate pharmacy student gain some experience in the collection and mathematical treatment of pharmacokinetic data. An experiment to provide the student with data for obtaining pharmacokinetic parameters is described, including lists of materials and equipment, with a student consent form appended. (MLW)

Introduces the analysis of a river as an excellent way to teach geochemical techniques because of the relative ease of sample collection and speed of sample analysis. Focuses on the potential sources of sample contamination during sampling, filtering, and bottle cleaning processes, and reviews methods to reduce and detect contamination. Includes…

Explains how controlling student access to data can be used as a strategy enabling students to take the role of a research geologist. Students develop models based on limited data and conduct field tests by comparing their predictions with the additional data. (DDR)
