The modern workplace environment is filled with interruptions due to the necessity of coworkers to communicate with each other. Studies have revealed that interruptions can disrupt the ability of a knowledge worker to concentrate on a task, which can impact task performance (TP). Communication interruptions are due, in part, to the unavoidable…

While many studies examining the effectiveness of using dynamic geometry software exist, few studies exist at the elementary school level. An extensive data analysis of student performance on New York State Math Assessments revealed that students in the fifth grade may not have had a clear understanding of interior angles sums of polygons, more…

This study involved the evaluation of the efficacy of a planned instructional program to facilitate understanding of the macroscopic, submicroscopic and symbolic representational systems when describing and explaining chemical reactions by sixty-five Grade 9 students in a Singapore secondary school. A two-tier multiple-choice diagnostic instrument…

This article summarizes the creation and implementation of a concurrent support class for TRS 92--Intermediate Algebra, a developmental mathematics course at Fort Lewis College in Durango, Colorado. The concurrent course outlined in this article demonstrates a statistically significant increase in student success rates since its inception.…

Through a study conducted in a core Foundations of Mathematics course at Western Oregon University, the authors investigate the thesis that peer-grading helps future elementary and middle school teachers improve their own attitudes about writing and assessing mathematics. Study participants were asked to provide scale responses to a series of…

This study introduces a learning environment integrating annotations with a dual-slide PowerPoint presentation for classroom learning. Annotation means a kind of additional information to emphasize the explanations for the learning objects. The use of annotations is to support the cognitive process for PowerPoint presentation in a classroom. The…

This pilot study of 1st graders who are academically at risk examined the effectiveness of child-centered play therapy (CCPT). The experimental group received biweekly, 30-minute play therapy sessions for 8 weeks. Findings indicated that these 1st graders participating in CCPT (n = 21) demonstrated a statistically significant increase on the Early…

Dichotic listening test (DL) is an important tool to disclose speech dominance in healthy subjects and in clinical cases. The aim of this study was to probe if focal epilepsy in children reveals a corresponding suppression of the ear reports contralateral to seizure onset site. Thus, 15 children and adolescents with clinically and…

Objective: This pilot study investigates the impact of an online, interactive simulation involving an Arab American Muslim patient on the knowledge, skills, and attitudes of 2nd-year medical students regarding culturally competent healthcare, both in general and specific to Arab American Muslim patients. Method: Participants (N = 199), were…

Background: Health professionals are looking to nutrition-based youth health interventions in K-12 schools to combat the growing obesity crisis; however, none have explored the influences of interventions guided by constructivist learning theory. Purpose: This study examined the influences of a constructivist-oriented nutrition education program…

Science teaching deals with abstract concepts and processes that very often cannot be seen or touched. The development of Java, Flash, and other web-based applications allow teachers and educators to present complex animations that attractively illustrate scientific phenomena. Our study evaluated the integration of web-based animated movies into…

Enthusiasm for problem-based learning (PBL) is widespread, yet there exists little rigorous experimental evidence of its effectiveness, especially in K-12 populations. Reported here is a highly controlled experimental study of PBL in a middle school population. Between- and within-subject comparisons are made of students learning the same material…

This study investigates the effectiveness of two variants of a prompting strategy that guides students to focus on important issues when learning in an ill-structured domain. Students in three groups studied individually Software Project Management (SPM) cases for a week, using a web-based learning environment designed especially for this purpose.…

This study investigates, through an experimental design, the effectiveness of a professional development program on teacher knowledge and practices and on student learning. The program consisted of a series of video-based modules designed to respond to needs of U.S. teachers, as highlighted by findings from the 1999 Third International Mathematics…

Williams syndrome (WS), a neurodevelopmental genetic disorder due to a microdeletion in chromosome 7, is described as displaying an intriguing socio-cognitive phenotype. Deficits in prosody production and comprehension have been consistently reported in behavioral studies. It remains, however, to be clarified the neurobiological processes…
