Interaction is crucial to student satisfaction in online courses. Adding synchronous components (virtual classroom technologies) to online courses can facilitate interaction. In this study, interaction within a synchronous virtual classroom was investigated by surveying 21 graduate students in an instructional technology program in the southeastern United(More)
PURPOSE Benign epilepsy with centrotemporal spikes (BECTS) is associated with mild cognitive deficits, especially language impairment. This study aimed to clarify whether children with BECTS with left- or right-hemispheric, or bilateral focus have specific neuropsychological language deficits when compared to healthy controls, whether these deficits(More)
Mobile technology opens the door for a new kind of learning called here and now learning that occurs when learners have access to information anytime and anywhere to perform authentic activities in the context of their learning. The purpose of this study was to investigate the effects of here and now mobile learning on student achievement and attitude. The(More)
This study investigated the effects of several elements of instruction (objectives, in,ormation, practice, examples and review) when they were combined in a systematic manner. College students enrolled in a computer literacy course used one of six different versions of a computer-based lesson delivered on the web to learn about input, processing, storage(More)
Executive Summary The use of computers has become pervasive and essential in today's world. Most of the universities offer a basic computer literacy course to the students. To meet the demand of computer-literate graduates, it is important to determine what constitutes a desired computer literacy course and how they should be taught. Formative evaluation of(More)
Instructional elements remain the foundation of current instructional design practice. Practice is the instructional element provided after learners have been given information required to master an objective and Navigation is the non-instructional element guides the learner on the sequence of instruction. Linear Navigation can be referred to as program(More)
BACKGROUND The mechanisms of childhood and perinatal arterial ischemic stroke (AIS) are poorly understood. Multiple risk factors include cerebral arteriopathy, congenital cardiac disease, infection, sickle cell disease, and maternal-fetal conditions in neonates. For infections and parainfectious conditions being the most important a possible inflammatory(More)
Studying morphological changes of subcortical structures often predicate neurodevelopmental and neurodegenerative diseases, such as Alzheimer's disease and schizophrenia. Hence, methods for quantifying morphological variations in the brain anatomy, including groupwise shape analyses, are becoming increasingly important for studying neurological disorders.(More)
