Stonecutter Mills, Inc., is a textile manufacturing company with a major production facility in Spindale, North Carolina. In the past few years, Stonecutter Mills employees have been given an opportunity to spend up to 2 hours a week on company time to participate in PLATO-supported learning at Isothermal Community College. Employees could choose to participate in PLATO curricula to improve specific technical skills associated with their jobs at the mill, improve their performance on General Educational Development (GED) testing, or improve specific reading, writing, and mathematics skills needed to pass the Comprehensive Adult Student Assessment System (CASAS) performance levels identified for their job areas at the mill. Approximately 140 different employees have used the PLATO system in this arrangement to date. This evaluation provided a detailed profile of PLATO use within this unique learning environment. The data collected during this evaluation included the PLATO data file for March 1995 through September 1997 as well as interviews with one of the program coordinators/instructors. Analyses of the data indicate that the average amount of time spent per curriculum was very high, as were the average number of tries for mastery. Almost every learner completing each module and course also mastered the module/course master tests. Suggestions for followup investigations are included. (Contains 76 figures and 20 tables.) (SLD)
