Procedures for implementing random assignment with trickle processing and ways they can be corrupted are described. A computerized method for implementing random assignment with trickle processing is presented as a desirable alternative in many situations and a way of protecting against threats to assignment validity. (SLD)

Describes a technique that sensitizes normative school-focused research and enables the practitioner's perspective to be incorporated into the research design. Bases procedure upon small group discussions called exploratory groups. Finds that the exploratory groups substantially influenced the extent that two related studies were able to address…

The authors investigated the efficacy of an interactive Web site, MyStudentBody.com: Alcohol (MSB:Alcohol) that offers a brief, tailored intervention to help heavy drinking college students reduce their alcohol use. They conducted a randomized, controlled clinical trial to compare the intervention with an alcohol education Web site at baseline,…

Enhanced interest in supervision training has corresponded with recognition of supervision as a profession in its own right. For many practicing professional counselors, supervision training has traditionally been unavailable. The present research used the Clinical Supervision Questionnaire to evaluate the effect of a supervision training program…

Children with autistic spectrum disorder and controls performed tasks of coherent motion and form detection, and motor control. Additionally, the ratio of the 2nd and 4th digits of these children, which is thought to be an indicator of foetal testosterone, was measured. Children in the experimental group were impaired at tasks of motor control,…

The role of recasts has been the subject of an increasing number of second language acquisition (SLA) studies in recent years, as has been the role of tasks. Few studies, nevertheless, exist that investigate the interaction between the two. The present study makes a preliminary excursion into this unexplored domain by examining the impact of two…

Purpose: This investigation sought to add to the extant literature on measures of normal tongue function, to provide information on measures of tongue function in a group of individuals with oral phase dysphagia, and to provide a comparison of these 2 groups matched for age and gender. Method: The Iowa Oral Performance Instrument was utilized to…

In activities requiring repetitive motions such as cycling, an individual gravitates to a natural cadence (NC). NC is seen as a "naturally occurring" phenomenon, a pace to which an individual reverts, as opposed to a consciously mediated pace, which is a learned ability. This article investigates this phenomenon by examining cyclists' NC, in this…

In the present study, voice onset time (VOT) measurements were compared between a group of individuals with moderate Alzheimer's disease (AD) and a group of healthy age- and gender-matched peers. Participants read a list of consonant-vowel-consonant (CVC) words, which included the six stop consonants. The VOT measurements were made from…

The purpose of this study is to design a constructivist learning environment that helps learning the limit concept. The study is a pretest-posttest quasi-experimental research. The control and the experimental groups were chosen from the students attending a calculus course. Worksheets were used to assess students' learning of the limit concept.…

Electronic performance support system (EPSS) technology provides a powerful mechanism for helping end-users operate complex systems. This article describes and discusses some research we have undertaken to explore their potential within academic library systems. Based on a needs analysis, an EPSS for supporting library users was designed and…

Two studies explored the role of implicit theories of intelligence in adolescents' mathematics achievement. In Study 1 with 373 7th graders, the belief that intelligence is malleable (incremental theory) predicted an upward trajectory in grades over the two years of junior high school, while a belief that intelligence is fixed (entity theory)…

This article reports on 2 studies with kindergarten and first-grade children from a low-achieving elementary school that provided vocabulary instruction by the students' regular classroom teacher of sophisticated words (advanced vocabulary words) from children's trade books that are typically read aloud. Study 1 compared the number of…

This study aimed at investigating the effect of multiple intelligences strategies comprising logical-mathematical intelligence, verbal-linguistic intelligence, intrapersonal intelligence and interpersonal intelligence on ninth grade students' reading comprehension achievement in an EFL setting. The population of the study consisted of all ninth…

This study reports an adaptive digital learning project, scientific concept construction and reconstruction (SCCR), that was developed based on the theories of Dual Situated Learning Model (DSLM) and scientific reasoning. In addition, the authors investigated the effects of an SCCR related to a "combustion" topic for sixth grade students…
