This study extends previous research that explores how visualization affordances that computational tools provide and social network analyses that account for individual- and group-level dynamic processes can work in conjunction to improve learning outcomes. The study's main hypothesis is that when social network graphs are used in instruction,…

Recursion is a concept that can be used to describe the phenomena and natural occurrences in many different fields. As many applications utilize computer software to model recursion, recursion is a particularly important concept in the computing discipline. However, it is a difficult concept for many undergraduate students to master. A Recursion…

Motor imagery (MI) refers to the mental rehearsal of a movement without actual motor output. MI training has positive effects on upper limb recovery after stroke. However, until now it is unclear whether this effect is specific to the trained task or a more general motor skill improvement. This study was set up to advance our insights into the…

This school-based study analyzed the impact of RGI on lung functioning (forced expiratory volume in 1 s [FEV[subscript 1]] and forced expiratory flow 25-75 [FEF[subscript 25-75]]) and by employing a multiple baseline design across 3 high school students with asthma and clinically diagnosed anxiety disorders. The RGI intervention took place for a…

A robust and reasonably simple experiment is described that introduces students to the visualization of nanoscale properties and is intended for a first-year laboratory. Silver nanoprisms (NPs) that display different colors due to variation of their plasmonic absorption with respect to size are prepared. Control over the size of the silver…

Computer-supported collaboration by spatially distributed group members still involves interaction problems within the group. This article presents an empirical study investigating the question of whether computer-supported collaborative problem solving by spatially distributed group members can be fostered by evoking knowledge and information…

Communicating an understanding of the forces and factors that determine a protein's structure is an important goal of many biology and biochemistry courses at a variety of levels. Many educators use computer software that allows visualization of these complex molecules for this purpose. Although visualization is in wide use and has been associated…

This paper deals with the design of interactivity in visualization tools. There are several factors that can be used to guide the analysis and design of the interactivity of these tools. One such factor is flow, which is concerned with the duration of interaction with visual representations of information--interaction being the actions performed…

This article describes a model for teaching Java Programming Language through Dynamic Learning Objects. The design of the learning objects was based on effective learning design principles to help students learn the complex topic of Java Programming. Visualization was also used to facilitate the learning of the concepts. (Contains 1 figure and 2…

This article begins with a definition of dyslexia as genetic, involving language processing and phonological awareness. It goes beyond reading and writing difficulties to include, for example, sequencing, orientation, short-term memory, speed, circumlocution, organisational skills, visual thinking, self-esteem and anger. Dyslexia, though…

In this article, the author begins with a proposition asking what if visual thinking were privileged in the English classroom and then proceeds to elaborate on a curriculum grounded on three principles: (1) sense and perception as starting points; (2) meta-conceptual links between visual and verbal texts; and (3) the art of visualization in…

A word cloud is a special visualization of text in which the more frequently used words are effectively highlighted by occupying more prominence in the representation. We have used Wordle to produce word-cloud analyses of the spoken and written responses of informants in two research projects. The product demonstrates a fast and visually rich way…

The students' difficulty which was found is in the problem of understanding, drawing diagrams, reading the charts correctly, conceptual formal mathematical understanding, and mathematical problem solving. The appropriate problem representation is the basic way in order to understand the problem itself and make a plan to solve it. This research was…

This article reports on a study analyzing the digital skills of 91 low-income students enrolled in writing remediation. Findings suggest that technological demands widen the equity dimensions of the college preparation gap by aggravating the academic challenges remedial writers already face. Suggestions to support the compound literacy needs of…

"Be a CHANGEMASTER" is a practical guide for school and district leaders that provides 12 strategies for overcoming resistance to change. Unlike more theoretical books, this text shows how to adopt a coaching style of leadership as a systemic change strategy. Numerous examples demonstrate how the strategies used in this book have led to…
