Data gathering for research on teaching in physical education appears to be heading into a new era, an era in which electronic data collection tools will merge with older measurement techniques to make the processes of storing, analyzing, and transporting data more efficient. The rapid development of microcomputing technology has reached the stage in which portable computers are now practical as state-of-the-art tools for on-site research projects. This article addresses one of the most critical problems for doing research on teaching using time based variables. In the past, when duration recording was the observational technique, there were two ways to collect data: either through multiple stop watches or through interval recording. Both methods have their limitations—one in the manipulation of the several watches and the other in converting interval data to accurate units of time. Outlined in this article is a microcomputer program for on-site duration coding, data analysis, permanent storage, and mainframe support for research on teaching physical education. The system is complex by design but practical to use. It produces total observation time, total time by category, frequency by category, mean length of occurrence, and the percent of total time each category was observed.
