Chemometric techniques such as partial least-squares (PLS) regression have been applied with huge success to a wide array of chemical problems including multicomponent analysis of analytes in complex mixtures. Despite this, there are few examples of laboratory pedagogical exercises that involve students in the acquisition of chemical data from…

Describes four experiments at the college freshman and sophomore levels which incorporate pre-lab viewing of visual aids, open-ended laboratory experiences, and use of the low-cost digital computer in both CAI and computational modes. (Author/DS)

Describes a laboratory exercise in ethology that has proven to be successful in teaching the analytical power of biological observation to students at the University of Wisconsin. (JR)

By using minimal equipment it is possible to demonstrate Faraday's Law. An electronic desk calculator enables sophomore students to solve a difficult mathematical expression for the induced EMF. Polaroid pictures of the plot of induced EMF, together with the computer facility, enables students to make comparisons. (PS)

Discusses how a spreadsheet might be used in an introductory physics laboratory. Describes three categories of spreadsheet uses, advantages of spreadsheet, layout, accuracy, and modifications. Gives an example of the variable mass rocket problem with typical display. (YP)

Introduces a computer solution of the oscillation of a mass suspended by a spring in a viscous liquid. Describes the equations of motion, spreadsheet solution, copying the formulas, plotting the results, and extending the applications. Presents spreadsheet and physics formulas for the step-by-step solution and spreadsheet solution. (YP)

A technique for the numerical identification of bacteria using normalized likelihoods calculated from a probabilistic database is described, and the principles of the technique are explained. The listing of the computer program is included. Specimen results from the program, and examples of how they should be interpreted, are given. (KR)

Presented is an experiment where the concentrations of three metal ions in a solution are simultaneously determined by ultraviolet-vis spectroscopy. Availability of the computer program used for statistically analyzing data using a multivariate linear regression is listed. (KR)

The use of microcomputers in the undergraduate chemistry laboratory is presented. Examples are included which can be implemented in the PET 2001. (SA)

Introduces two hands-on experiences, related to rotational motion and moment of inertia. Discusses the experimental procedures and provides figure of apparatus. (YP)

Discussed is a program created to serve as an instructional tool for teaching basin analysis. Described is the use of the program for interpreting plots resulting from backstripping methods. Included in the discussion are implementation, applications and availability of the "Subside!" program. (CW)

Describes a laboratory experiment using AMPAC (a computer program) in conjunction with infrared spectroscopy. The experimental procedure and a list of questions for discussion are provided. Typical data are presented. (YP)

The assumptions common to all capture-recapture models for estimating population size are reviewed. A simulation using either a playing board, counters, and dice or computers is described. Classroom implications of using the board game are discussed. (KR)
