A single subject alternating treatment design across three teacher-student dyads was used to investigate the comparative impact on student academic engaged time (AET) of three common opportunities to respond (OTR) interventions, a) guided notes, b) class-wide peer tutoring, and c) response cards. Subjects were three students with…

Scientific inscriptions--graphs, diagrams, and data--and argumentation are integral to generating and communicating scientific understanding. Scientific inscriptions and argumentation are also important to learning science. However, previous research has indicated that learners struggle to understand and learn science content represented in…

We analyze the interaction of 3 students working on mathematics problems over several days in a virtual math team. Our analysis traces out how successful collaboration in a later session is contingent upon the work of prior sessions and shows how the development of representational practices is an important aspect of these participants' problem…

This study describes the classroom environment that students with visual impairment typically experience in regular Australian early education. Adequacy of the classroom environment (teacher training and experience, teacher support, parent involvement, adult involvement, inclusive attitude, individualization of the curriculum, physical…

Established in 1873, Drury College in Springfield, Missouri, provided a unique experience for their undergraduate students. A limited amount of research has been conducted on the institution but no work has been done to specifically look at the undergraduate student experience. Using archival research methods and information from literature on…

The present study focuses on the short-term effects of electronic entertainment media on memory and learning processes. It compares the effects of violent versus non-violent computer game content in a condition of playing and in another condition of watching the same game. The participants consisted of 83 female and 94 male adolescents with a mean…

E-learning has seen incredible growth in the first decade of the 21st century. This growth is particularly noticeable in institutions of higher education. Even though distance learning has long been the method by which remote students have obtained course credit through correspondence study, e-learning is popular even among traditional on-campus…

The authors used functional magnetic resonance imaging (fMRI) to investigate neural activation during a semantic-classification/object-recognition task in 13 persons with Down syndrome and 12 typically developing control participants (age range = 12-26 years). A comparison between groups suggested atypical patterns of brain activation for the…

We constructed a simple demonstration setup to simulate an extrasolar planet and its star revolving around the system's centre of mass. Periodic dimming of light from the star by the transiting planet and the star's orbital revolution simulate the two major ways of deducing the presence of an exoplanet near a distant star. Apart from being a…

How many children entering a classroom already have a day/night explanation that employs a turning Earth? This question ought to be of interest to most teachers, along with questions such as "What are children thinking after one's teaching of this topic?" The author has used a simple diagram and tick-box response sheet to help him assess the range…

This paper represents a response to Kaufmann's article in this issue on the subject of heteronarrative analysis. The author highlights three elements of Kaufmann's argument to be especially persuasive: the use of narrative as an organizing principle of identity; the propensity of identity to be inflected by heteronormative logic; and the use of…

People typically seek treatment for addiction only when faced with a major crisis. Understanding the trajectory of substance use and treatment seeking may assist in identifying points for intervention. In this study I explored the use of visual methods with in-depth interviews to represent people's substance use, critical events, and treatment…

The purpose of this study was to examine the effects of visual supports on the performance of the Test of Gross Motor Development (TGMD-2) for children with autism spectrum disorder (ASD). Participants (N = 22) performed the TGMD-2 under three different protocols (traditional protocol, picture task card protocol, and picture activity schedule…

With the advent of technologies that allow lecturers to develop presentations using software such as Microsoft PowerPoint, Apple Keynote, and OpenOffice Impress (referred to generically here as "slideware"), lectures and meetings are beginning to resemble cinematic experiences rather than the text filled transactions that have been the norm for…

Most undergraduate chemistry courses and a few high school honors courses, which focus on physical chemistry and quantum mechanics, are highly mathematically-oriented. At the Technion, Israel Institute of Technology, we developed a new module for high school students, titled "Chemistry--From 'the Hole' to 'the Whole': From the Nanoscale to…
