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…

There is a misconception among undergraduate students that global warming is caused by holes in the ozone layer. In this study, we evaluated the presence of this and other misconceptions surrounding atmospheric chemistry that are responsible for the entanglement of the greenhouse effect and the ozone hole in students' conceptual frameworks. We…

Presented are some descriptive background materials and the directions for an experiment which provides an introduction to on-line computer instrumentation. Assumes students are familiar with the Purdue Real-Time Basic (PRTB) laboratory computer system. (PR)

Describes an experimental use of computer terminals for instructional purposes in a university-level general physics course over a two-year period. Programs have been written to simulate physical problems otherwise difficult for the student to investigate. (Author/DS)

An experiment assigned in a role-playing'' modern physics lab for juniors who are challenged to obtain accurate measurement with suboptimum apparatus through correct analysis. They also investigate the influence of systematic errors using a small computer. (DF)

Describes the use of a desk-top computer as an aid to analyze strobe photographs. Applications are illustrated for collision of pucks and the motion of a ball on a rubber band. (DS)

Explains a technique to create animated films for aid in the instruction of relativistic mechanics through the use of a computer. (CP)
