This article investigates the conditions under which diagrammatic representations support collaborative argumentation-based learning in a computer environment. Thirty dyads of 15- to 18-year-old students participated in a writing task consisting of 3 phases. Students prepared by constructing a representation (text or diagram) individually. Then…

A concrete example is used to illustrate maximum likelihood estimation of a structural equation model with two unknown parameters. The fitting function is found for the example, as are the vector of first-order partial derivatives, the matrix of second-order partial derivatives, and the estimates obtained from each iteration of the Newton-Raphson…

In years past, pencils and paper, chalk and chalkboards were common sights on school campuses. Fast forward to 2007--personal laptops, PDAs and PowerPoint presentations are the communication tools of choice. The traditional images that came to mind when remembering one's school days are no longer. Evolving technology and innovations in school…

The experience of "virtual reality" can consist of head-tracked and stereoscopic virtual worlds, spatialized sound, haptic feedback, and to a lesser extent olfactory cues. Although virtual reality systems have been proposed for numerous applications, the field of education is one particular application that seems well-suited for virtual…

Background: The area of research aimed for a more efficient e-learning is slowly widening from purely technical to the areas of psychology, didactics and methodology. The question is whether the text or background color influence the efficiency of memory, i.e. learning. If the answer to that question is positive, then another question arises which…

This Independent Learning Project (ILP) discusses the best practices in educational technology to improve the behavior, instruction, and learning of at-risk youth, for whom technology offers unique opportunities. Research is compiled from numerous scholarly print and online sources. A guide for teachers provides detailed strategies, software…

Purpose: To describe the nature and frequency of the aided language stimulation program and determine the effects of a 3-week-long aided language stimulation program on the vocabulary acquisition skills of children with little or no functional speech (LNFS). Method: Four children participated in this single-subject,multiple-probe study across…

This paper examines the difficulty in reading French experienced by English students at Advanced Subsidiary Level (AS), taken at age 17, and the need for vocabulary learning to assist comprehension. Research has shown that intermediate learners need knowledge of some 5000 word families, and that specifications for the General Certificate of…

Over a period of 150 years, photographic images have contributed to how we see and think about the world, ourselves, and others. Individuals who are particularly resistant to therapy and those who communicate better with the use of visual aids may not benefit from standard counseling practices alone. Although verbal communication is vital in most…

In an effort to better prepare undergraduate students to read and critically evaluate scientific literature, a journal club experience was introduced into a university's bachelor of science curriculum. As a result of this experience, students have been found to be more thoughtful, poised, and articulate presenters, a fact that they, the students,…

Six older adults with probable Alzheimer's disease (AD) were trained to recall a name-face association using the spaced retrieval technique. In this study, we retested these persons in a 6-month follow-up program. For half of the participants, three booster sessions were administered at 6, 12, and 18 weeks after original training to promote…

This paper reports on exploratory research that examined how students learn Science with an interactive whiteboard. In this study, the IWB was found to support a range of multimodal representation types including verbal, graphic, tabular, mathematical, pictorial and kinaesthetic. The affordances offered by the technology are discussed in this…

This study investigated the effectiveness of three different levels of enhancement strategies utilized to facilitate students' learning from static and animated visualization when taking the time-on-task into consideration. Participants were randomly assigned to six treatment groups, and then took four criterion measures. The time-on-task was…

Many epistemic activities, such as spatial reasoning, sense-making, problem solving, and learning, are information-based. In the context of epistemic activities involving mathematical information, learners often use interactive 3D mathematical visualizations (MVs). However, performing such activities is not always easy. Although it is generally…

After a teaching experience with the children of Ecuador with so little support, the author has come to greatly appreciate what is available for teachers in the states. Sometimes the best encouragement for a new teacher of FLES is a success story straight from the classroom. In this article, the author shares a few of the tools she has picked up…
