Abstract
As the focus on health-related physical education increases, promoting physical activity leading to the development of physical fitness becomes an important component of school physical education programs. To determine the status and effect of teaching processes related to physical activity and fitness in physical education, it is necessary to have instrumentation that produces reliable, valid, and usable scores for the population in which they are used. The purpose of this study is to compare the data produced by the previously validated and often used System for Observing Fitness Instruction Time (SOFIT) instrument (McKenzie, Sallis, & Nader, 1991) with a computerized instrument, the Computer-SOFIT (C-SOFIT). The categories of the C-SOFIT instrument are exactly the same as those of the interval coding system, the SOFIT instrument. C-SOFIT is a duration coding instrument that was written in the C computer language and pilot tested in a number of classes with different coders to make it usable in physical...
