This study examined changes in rhythmic arm shaking and laterality biases in infants observed longitudinally at three points: just prior to, at, and just following reduplicated babble onset. Infants (ranging in age from 4 to 9 months at babble onset) were videotaped at home as they played with two visually identical audible and silent rattles…

We report two experimental studies on the potentially detrimental effects of nonshared, external representations in an instructional setting. Domain experts viewing an external representation responded to E-mail inquiries for medical advice written by people who were unable to see this external representation. Based on research on expert-layperson…

Purpose: The purpose of this paper is to describe the Images for All digitisation project at the Royal Scottish Geographical Society, and lessons learned from it. Design/methodology/approach: This paper describes the background to the project and collections held. It focuses on the development of the project web site, the digitisation of 100…

This article details a heuristic history teachers can use in assigning and evaluating multimedia projects in history. To use this heuristic successfully, requires more than simply following the steps in the list or stages in a recipe: in many ways, it requires a reorientation in what it means to think like an historian. This article, as much as…

This article explores PowerPoint slideshow's capacities for introducing history teachers and students to the pictorial and digital turns for representing and narrating the past. Based upon this research, the author argues that image-dominated PowerPoint slideshow provides teachers and students with a unique and powerful tool for composing and…

This paper introduces various visual models for the analysis and description of learning processes. The models analyse learning on two levels: the dynamic level (as a process over time) and the functional level. Two types of model for dynamic modelling are proposed: the session trace, which documents a specific learner in a particular learning…

There's no shortage of library management books out there--but how many of them actually tackle the little details of day-to-day management, the hard-to-categorize things that slip through the cracks of a larger handbook? "Library Management Tips that Work" does exactly that, addressing dozens of such issues facing library managers, including: (1)…

This paper investigates learner response to a novel kind of intonation feedback generated from speech analysis. Instead of displays of pitch curves, our feedback is flashing lights that show how much pitch variation the speaker has produced. The variable used to generate the feedback is the standard deviation of fundamental frequency as measured…

Introduction: This paper extends a series on summaries of Web objects, in this case, the alt attribute of image files. Method: Data were logged from 1894 pages from Yahoo!'s random page service and 4703 pages from the Google directory; an img tag was extracted randomly from each where present; its alt attribute, if any, was recorded; and the…

The equations for the liquid and gas lines in the binary temperature-composition phase diagram are derived by approximating that delta(H)[subscript vap] of the two liquids are equal. It is shown that within this approximation, the resulting equations are not too difficult to present in an undergraduate physical chemistry lecture.

At the risk of seeming to make exaggerated claims for visual methodologies, what I set out to do is lay bare some of the key elements of working with the visual as a set of methodologies and practices. In particular, I address educational research in South Africa at a time when questions of the social responsibility of the academic researcher…

The purpose of this practice brief is to provide schools, districts, and states with background knowledge about best practices for older students who struggle to read. It focuses on the reading skills that adolescents need to more fully access content-area curricula and, in turn, secure a productive future. The authors define adolescent reading as…

Poland subscribes to an abstinence-only model of reproductive health education called "Education for Life in the Family." The aim of this study was to determine if the perceptions of adolescent mothers could be used to improve delivery of the Polish model of education. This study was conducted using focus group interviews with fourteen…

This article presents the findings from classroom based research into the use of SMART Boards (interactive whiteboards) with kindergarten children. SMART Boards have been used successfully over the past 8 years at Abbotsleigh Junior School as innovative ways to enhance teaching and learning and facilitate assessment in primary Science. Key…

This study employs the Excel function to design dynamic visual activities for factors and multiples word problem learning. A teaching experiment was carried out eight times in 4 weeks on three fifth grade students. The result showed that after using multiple-linked representations activities, students made greater progress in understanding target…
