This is one of a series of reports which provide definitions of and descriptive data on the variables used in the Comparative Study of Phase IV of the Individually Guided Education (IEG) Evaluation Project. Phase IV investigated three curriculum programs specifically designed to be compatible with instructional programming for the individual student: (1) the Wisconsin Design for Reading Skills Development (WDRSD); (2) Developing Mathematical Processes (DMP); and (3) Prereading Skills (PRS). Information on instructional methods and pupil outcomes for grades 2 and 5 was collected from achievement monitoring and domain referenced tests, teacher logs, and classroom observations. This report focuses on three variables created from the observational data: nonapplied, available, and engaged time. Nonapplied time is time within the designated skills period spent in unrelated activities. Available time is the time actually available for skill instruction. Engaged time is the portion of the instructional period when students are actively involved in learning. Tables 1-8 report average number of hours and percentage of observed nonavailable, available, and engaged time, by period, for reading and math skills by grade. Tables 13-16 enumerate reading and math general objectives for each grade, and provide the total number of hours and percentages of time allocated to each objective. (BS)
