The purpose of this study was to compare the isolated effects of cover-copy-compare (CCC) with the combined effects of CCC and two types of performance feedback (i.e., digits correct and incorrect per minute) on sixth grade students' mathematics fluency and accuracy. An alternating treatments design was employed to compare treatments across 16…

An adapted alternating treatments design was used to evaluate and compare the effects of two procedures designed to enhance math fact accuracy and fluency in an elementary student with low cognitive functioning. Results showed that although the cover, copy, compare (CCC) and the taped problems (TP) procedures both increased the student's math fact…

Two quasi-experimental field studies were conducted to evaluate the psychometric equivalence of computerized and paper-and-pencil job satisfaction measures. The present research extends previous work in the area by providing better control of common threats to validity in quasi-experimental research on test mode effects and by evaluating a more…

We assessed the effects of using LearnStar[TM], an interactive, computer-based teaching tool, as an in-class exam review method. Students with higher LearnStar review scores had higher grades. Furthermore, students' satisfaction ratings indicated that LearnStar reviews were more enjoyable and conducive to participation than traditional reviews.…

A method is presented for generalized canonical correlation analysis of two or more matrices with missing rows. The method is a combination of Carroll's (1968) method and the missing data approach of the OVERALS technique (Van der Burg, 1988). In a simulation study we assess the performance of the method and compare it to an existing procedure…

"How New York City's Charter Schools Affect Achievement" estimates the effects on student achievement of attending a New York City charter school rather than a traditional public school and investigates the characteristics of charter schools associated with the most positive effects on achievement. Because the report relies on an…

Relatively few experimental studies have examined the effectiveness of study guides on student exam performance. The authors compared exam scores for students who were given instructor-generated study guides versus students who generated their own study guides. Participants were undergraduates enrolled in three identical sections of an…

A Monte Carlo study examined the statistical performance of single sample and bootstrap methods that can be used to test and form confidence interval estimates of indirect effects in two cluster randomized experimental designs. The designs were similar in that they featured random assignment of clusters to one of two treatment conditions and…

Purpose: In conjunction with curricular changes, a process to develop integrated examinations was implemented. Pre-established guidelines were provided favoring vignettes, clinically relevant material, and application of knowledge rather than simple recall. Questions were read aloud in a committee including all course directors, and a reviewer…

The purpose of the analyses reported in this paper was to compare performance on the GED (General Educational Development) Tests, U.S. edition, across three groups of examinees: (a) graduating high school seniors in the GED Tests U.S. 2001 norm group, (b) GED Tests candidates who took one or more tests in the U.S. in 2002-2004, and (c) GED Tests…

"Algebra for everyone" has been a popular reform, though not commonly implemented and not fully evaluated. Through investigation, one might be able to determine whether courses deemed equivalent to a traditional college preparatory algebra course provide an equitable understanding of algebra concepts and skills, while controlling for…

The project of comparative cognition benefits from common measures across species. We report here on five experiments using the violation of expectancy looking time measure with free-ranging rhesus macaques ("Macaca mulatta"), each designed to build on current knowledge concerning spontaneous representations of number. Each subject, tested in only…

We use data on statewide end-of-course tests in North Carolina to examine the relationship between teacher credentials and student achievement at the high school level. The availability of test scores in multiple subjects for each student permits us to estimate a model with student fixed effects, which helps minimize any bias associated with the…

In this study, the research problem was: "Is the computer based physics instruction as effective as laboratory intensive physics instruction with regards to academic success on electric circuits 9th grade students?" For this research of experimental quality the design of pre-test and post-test are applied with an experiment and a control…

This study compared four methods for setting item response time thresholds to differentiate rapid-guessing behavior from solution behavior. Thresholds were either (a) common for all test items, (b) based on item surface features such as the amount of reading required, (c) based on visually inspecting response time frequency distributions, or (d)…
