Randomized experiments are often seen as the "gold standard" for causal research. Despite the fact that experiments use random assignment to treatment conditions, units are seldom selected into the experiment using probability sampling. Very little research on experimental design has focused on how to make generalizations to well-defined…

An alternative method of identifying effective schools, based on the concept of effective schools as statistically atypical, was tested. This paper investigates the issue of consistency of the identification of what is termed "exceptional" schools. The following tests were administered to all first through fourth graders in 431 schools…

A process-product study explored the relationship between quantity and quality of time spent on reading instruction and student achievement in reading. Subjects, 22 third and fourth grade teachers and their 480 students in a small school district in the Piedmont region of South Carolina, used self-report logs to record the quantity of time devoted…

A study compared the teaching methods of basal readers to writing/reading integration as they effect reading comprehension. Forty fourth-grade students from an urban area of New England completed the Reading Comprehension Subtest of the Comprehensive Test of Basic Skills (CTBS) for grade 3 as a pretest. A control group of 20 students were…

A study determined the effect of shared writing activities on reading comprehension. The subjects, 40 second- and third-grade students from a suburban school in Mercer County, West Virginia, completed the Reading Comprehension Subtest of the Comprehension Test of Basic Skills (CTBS) for grade 2 as a pretest. A control group of 20 students were…

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…

School effectiveness indices (SEIs), based on regressing test performance onto earlier test performance and a socioeconomic status measure, were obtained for eight subject-grade combinations from 485 South Carolina elementary schools. The analysis involved school means based on longitudinally matched student data. Reading and mathematics…

South Carolina's School Incentive Reward Program Program (SIRP) based on year-to-year gains in reading and mathematics achievement, which seemed to have face validity, was evaluated, particularly its use of the relative gains of students in only the highest grade in the school as the basis for the awards. When this requirement was relaxed so that…

Assesses the results of a study of spelling development on the junior high level. Concludes that spelling instruction in the upper grades is worthy of serious consideration. (NKA)

Ninth grade Elementary Secondary Education Act (ESEA) Title I evaluation results in reading and English-writing projects were compared, using the RMC Model A with local empirical norms, Model A with national interpolated norms, and Model B. The Comprehensive Tests of Basic Skills (CTBS)--Total Reading and Total Language subtests--were administered…

Funded through the Ohio Disadvantaged Pupil Program Fund, the Instructional Assistant Program of the Columbus, Ohio public schools provided direct instructional service to selected pupils in the classroom setting. The program was located in 60 buildings, with an equivalent of 147 assistants serving 202 teachers and 2048 pupils in kindergarten and…

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…

A study compared the reading achievement of first grade students who attended half-day kindergarten to that of students who attended full-day kindergarten. Subjects, 67 students in urban Newark, New Jersey, who had attended half-day and 66 students who had attended full-day kindergarten, were given the first grade Comprehensive Tests of Basic…

The accuracy of trait estimates obtained from three vertical equating methods was examined. The procedures studied included two anchor test designs and a single-group design. Data from two content areas and two grade combinations were studied. A three-parameter logistic model was used to perform the equatings. The results obtained were used to…

School effectiveness indices based on regressing achievement test scores onto earlier scores and a socioeconomic status measure were obtained for South Carolina students in grades one to four. Results were unstable across grades, and grade-to-grade correlations were more significant for mathematics achievement than for reading. (Author/GDC)
