Numerous studies have shown that thinking aloud while reading can be an effective instructional technique in helping students improve their reading comprehension. However, most of the studies that examined the effects of think-aloud involve subjects reading individually and carried out in isolation away from the classroom context. Recently,…

Under the "Math Science Partnership Grant," the Maui Hawaii Educational Consortium sought scientifically based evidence for the effectiveness of Carnegie Learning's "Cognitive Tutor[R]" (CT) program as part of the adoption process for pre-Algebra program. During the 2006-2007 school year, the researchers conducted a follow-on…

The purpose of this study was to compare two non-parametric procedures, the Mantel-Haenszel (MH) procedure and the simultaneous item bias (SIB) procedure, with respect to their Type I error rates and power, and to investigate the conditions under which asymptotic distributional properties of the SIB and MH were obtained. Data were simulated to…

This protocol study: (1) tested the instructional use of a model of the decision processes involved in revising after feedback; (2) examined whether feedback specifying a text problem was a stronger cue to revision than feedback summarizing the point of a paragraph or predicting forthcoming text; and (3) compared the quality of texts revised after…

The pretest-posttest design referred to as Design 2 by Campbell and Stanley (1963) is commonly used in educational research and evaluation. The tenability of the assumption of a zero population difference commonly used with this design is questioned. A nonzero population estimate based on the mean difference observed in test-retest reliability…

Student team techniques, involving two conceptually distinct components--a cooperative reward structure, in which students are evaluated and rewarded based on the performance of the group as a whole, and a cooperative task structure, in which students are encouraged to peer tutor--have had positive effects compared to control methods on academic…

A study was conducted of experimental mortality (subjects' drop-out) in counter-attitudinal advocacy research, a line of research that explores the extent to which people can be induced to persuade themselves to a new attitude. Subjects were 54 volunteers from undergraduate speech classes. The study involved three stages: a pretest for attitude,…

THE PROJECT SOUGHT TO ESTABLISH VOCATIONAL ASSESSMENT PROCEDURES, PROVIDE A WORK CONDITIONING PROGRAM TO INCREASE WORK POTENTIAL, AND PROVIDE AFTERCARE SERVICE AND FOLLOWUP. THE MAJOR HYPOTHESIS WAS THAT PATIENTS GIVEN A PROGRAM OF WORK CONDITIONING WERE MORE LIKELY TO BE PLACED IN WORK SITUATIONS IN THE COMMUNITY AND TO REMAIN LONGER OUTSIDE THE…

A study was made to see if an educational program on the safe and proper use of pesticides would increase the opinion leadership activities of pesticide dealers and the amount of quality of information they conveyed to their customers and other dealers. The dealers selected came from eight rural counties and two urban communities in Nebraska; they…

Following specialized training in which naval dental assistants were taught to insert restorations in cavities prepared by dental officers, clinical tests were applied to determine how much more a dental officer can accomplish when he delegates certain procedures to specially trained assistants, to evaluate the quality of the restorations, and to…

A sample of 96 ninth-grade vocational agriculture students in 21 Illinois high schools participated in a study of the relationship between socioeconomic status and reading comprehension. An instructional unit was tested for reading level and rewritten at an easier level. Students were classified by socioeconomic class and randomly assigned to…

Studied was the effect of art education on productive changes in perceptual, cognitive, and attitudinal styles, and on the art aptitudes of disadvantaged youth. The study examined the assumption implicit in many school programs that art education is somehow beneficial to poor and minority group students. The research design divided teachers of…

Research indicates the existence of a relationship between the level of visual perceptual skills in the first grade and academic success in later grades. Special visual-motor training was given to some 275 primary school children with a like number of children acting as a control group. The control group was one grade ahead of the experimental…

The object of this study was to measure videotape recorded playbacks as a variable in mastery of a basic speech course in an experimental college program for low income underachieving students. The beginning speech course is required of all these students in the Experiment in Higher Education at Southern Illinois University. Experimental and…

An account is presented of the development of a job performance test for the Learner Centered Instruction (LCI) weapon control systems mechanic/technician Air Force course. The performance test was administered to the LCI experimental course subjects as well as the control course subjects upon graduation. Test items are, for the most part, based…
