This paper addresses four issues in the design and execution of behavioral observation in classrooms. 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. All students were pre-tested in February 1978 in reading, language arts, math and social studies using the Comprehensive…

Four elements of a model of effective instruction are instructional Quality; Appropriate levels of instruction; Incentive; and Time. In the QAIT model, all four elements must be adequate, and improvements in multiple elements may produce larger learning gains than improvement in any one. (SK)

This collection assembles some of the most important works from the writings of Robert E. Slavin and presents them in individual chapters with introductions and commentary to set them in context. The works cited give educators and educational researchers a single source for the most important work of Slavin and his colleagues. The first section,…

A discussion of tracking, or student grouping by academic ability, looks at arguments for and against such tracking, outlines several alternatives, including cooperative learning, active teaching strategies, and extended learning time for low-achievers. It is concluded that tracking is ineffective, harmful to many, and undermines democratic…

Component-building research on practical issues of instructional design can make a substantial contribution to research-based school improvement. Component-building research consists of rigorous within-school experiments that test various components of instruction for effects on student achievement. Research would address practical issues that…

This paper describes the second year of the Success for All program, which tries to assure that each student in an inner-city school succeeds in acquiring basic skills in the early grades. The program was first implemented in the 1987-88 school year in Abbottson Elementary School in Baltimore. First year results revealed substantially higher…
