Background: Several theorists maintain that exact number abilities rely on language-relevant processes whereas approximate number calls on visuo-spatial skills. We chose two genetic disorders, Williams syndrome and Down's syndrome, which differ in their relative abilities in verbal versus spatial skills, to examine this hypothesis. Five…

Background: Child survivors of a catastrophic earthquake in Turkey were evaluated three and a half years after the event, and three years after a sub-group participated in a teacher-mediated intervention developed by the authors. The goal of this follow-up study was to determine the long-term effectiveness of the original intervention. Methods:…

This paper reviews studies that have contrasted the effectiveness of structured-input instruction with output-based instruction. It then presents results from a study comparing the relative effects of structured-input and output-based instruction on students' ability to comprehend and produce direct object pronouns in second language French. Three…

This study examines interventions designed to improve communication between individuals who take care of children with ADHD. A teacher rating of 6,171 elementary school children identifies 1,573 children with ADHD or with high risk for ADHD. Parent interviews and information from teachers are collected on 243 children who are randomized into…

This research compared the effects of a Programmed Learning Sequence (PLS) (Dunn & Dunn, 1993) versus Traditional Teaching (TT) on 100 sixth-grade Bermudian students' test scores on a Fractions Unit. Fifty-three males' and forty-seven females' learning styles were identified with the "Learning Style Inventory" (LSI) (Dunn, Dunn,…

For beginning programmers, inadequate problem solving and planning skills are among the most salient of their weaknesses. In this paper, we test the efficacy of natural language tutoring to teach and scaffold acquisition of these skills. We describe ProPL (Pro-PELL), a dialogue-based intelligent tutoring system that elicits goal decompositions and…

The purpose of this study is to demonstrate that dynamic assessment based instruction increases children's learning by using a quasi-experimental research design in Korea. In this study, dynamic assessment is defined as a measurement method of the zone of proximal development (ZPD) as well as the qualitative and quantitative diagnostic information…

Universities have recognized student attrition as a problem for some years, and measures to improve this critical issue are being sought. One such effort used at Lamar University is the Monitored Probation (MP) program. The MP program is a comprehensive early intervention academic retention program intended to assist with the academic success of…

Although substantial literature exists regarding learning with visuals, most consider text the primary channel with varying amounts of visuals explored as a secondary channel. This study considered the effectiveness of visuals-only procedural guides versus visuals plus added text, using visuals as the primary channel and using visuals developed…

This study examined the effects of two training methods (interest-based method vs. traditional method) in improving independent problem solving performance of students with mild mental retardation representing three cultural backgrounds (African-American, European-American and Nigerian) as measured by Edeh Scale of Interpersonal Problem…

Contrary to conventional expectations, the reality of computing education in Taiwan's vocational schools is not so practically oriented, and thus reveals much room for improvement. In this context, we conducted a quasi-experiment to examine the effects of applying web-based problem-based learning (PBL), web-based self-regulated learning (SRL), and…

This study investigated the effects of the WebQuest Writing Instruction (WQWI) program on Taiwanese EFL learners' writing performance, writing apprehension, and perception of web-resource integrated language learning. Participants were students from two junior college classes. One class received traditional classroom writing instruction and the…

This research project consists of a randomized experiment in a few of the Reynoldsburg City Schools. The primary purpose of this research is to produce scientifically based evidence of the comparative effectiveness of the "Scott Foresman Science" ("SFScience)" program. The question being addressed by the research is whether…

This research project consists of a randomized experiment in St. Petersburg Catholic Schools. The question being addressed by the research is whether "Scott Foresman Science" is as effective as the current curricula being used in the participating campuses of the Roman Catholic Diocese of St. Petersburg. The research focuses on 3rd, 4th,…

This research project consists of a randomized experiment in Visalia Unified School District. The question being addressed by the research is whether "Scott Foresman Science" is as effective as or more effective than the curriculum being used at each site. Since Scott Foresman Science provides a significant reading component, the authors…
