These four issues relate to the consequences of using different observation intervals, schedules of observation, student sampling methods, and definitions of on-task and off-task behavior for reliability, means, and correlations of time on-task…

The consequences of using alternative measures of time and achievement are examined in an observational study of 18 elementary school classes. The extent to which choice of the same model linking time and learning for all students was implicated in the inconsistent results is examined. (Author/GK)

How various methodological decisions may influence studies of the effect of time-on-task on achievement are examined. Subjects were students in grades 2-5 in 18 classes taught by 12 teachers in a rural Maryland school district.

Extensive detailed observations of students, teachers, and instructional material were used to explore the plausibility of a causal model of the effects of reading behaviors and instruction on students' reading performance.…
