This article is based on results of a quasi-experimental study in which the efficacy of the strategies approach for reviewing grammar and punctuation concepts was assessed in a business communication course. The control group studied rules-based review materials; the treatment group studied strategies-based review materials. On the three sets of…

The aim of this study is to compare the effectiveness of conceptual change text instruction (CCT) in the context of energy in chemical reactions. The subjects of the study were 60, 10th grade students at a high school, who were in two different classes and taught by the same teacher. One of the classes was randomly selected as the experimental…

This study aimed to investigate the comparative value of experimenting with physical manipulatives (PM) in a sequential combination with virtual manipulatives (VM), with the use of PM preceding the use of VM, and of experimenting with PM alone, with respect to changes in students' conceptual understanding in the domain of heat and temperature. A…

This study examined the accuracy of a curriculum-based assessment for use during the eligibility process for Individuals with Disabilities Education Improvement Act (IDEA) services.

We report the results of a study designed to investigate the effectiveness of peer-led, small-group discussions in a large (N greater than 400) general chemistry course usually taught in a traditional lecture format. The administrative structure, the training of the peer facilitators, and the achievement of students exposed to this environment…

In this study, the implementation effects of a staff development program on cooperative learning (CL) for Dutch elementary school teachers were studied. A pre-test-post-test non-equivalent control group design was used to investigate program effects on the instructional behaviours of teachers. Based on observations of teacher behaviour during…

In order to examine whether any observed relationship between phonological awareness and reading ability in Down syndrome reflects the typical use of a phonologically based approach to reading, 12 children and young adults with Down syndrome were assessed for reading and phonological awareness skills. They were compared to a control group of 14…

We investigated the effects of a highly rated commercial electronic book (e-book) for young children on kindergarteners' emergent literacy skills within the context of paired peer versus individual use of the e-book. The sample of 110 kindergarteners had a mean age of 5.64 years and approximately equal numbers of boys and girls, randomly chosen…

Background: Response-contingent time-out has been shown to be an effective technique for enhancing fluency in people who stutter. However, the factors that determine individual responsiveness to time-out are not well understood. Aims: The study investigated the effectiveness of using response-contingent time-out to reduce stuttering frequency in…

Comprehending high-imagery sentences like "The number eight when rotated 90 degrees looks like a pair of eyeglasses" involves the participation and integration of several cortical regions. The linguistic content must be processed to determine what is to be mentally imaged, and then the mental image must be evaluated and related to the sentence. A…

To rule out threats to internal validity, proposes a control group design in which control group subjects are given an alternate treatment that they perceive as equally desirable to and that is similar in duration and procedures to the experimental treatment but that is concerned with dependent variables unrelated to the experimental treatment.…

The major aim of the present investigation was to determine if delinquent youths show neuropsychological deficits on the Lurias' Neuropsychological Investigation. Of the 11 general categories examined, only two, cutaneous and kinesthetic functions, did not statistically discriminate between a sample of 28 subjects from a California juvenile…
