Much knowledge in chemistry exists at a molecular level, inaccessible to direct perception. Chemistry instruction should therefore include multiple visual representations, such as molecular models and symbols. This study describes the implementation and assessment of a learning unit designed for 12th grade chemistry honors students. The organic…

A problem-posing system is developed with four phases including posing problem, planning, solving problem, and looking back, in which the "solving problem" phase is implemented by game-scenarios. The system supports elementary students in the process of problem-posing, allowing them to fully engage in mathematical activities. In total, 92 fifth…

Technological infrastructure is often taken for granted in our day to day lives until it breaks down, usually because it invisibly supports tasks otherwise. Previous work in HCI has focused on how people react and deal with breaks in infrastructure as well as how to help people to fix or exploit these breaks. However, few have sought to understand…

Prompting students to self-explain during problem solving has proven to be an effective instructional strategy across many domains. However, despite being called "domain general", very little work has been done in areas outside of math and science. In this dissertation, I investigate whether the self-explanation effect holds when applied…

This paper discusses the results of experiment on teaching CALL elements to second year Linguistics students as a part of syllabus of practical studies in IT course. The syllabus of the CALL part of IT course is described which is followed by the discussion about experience in implementing it, achieved results and arisen difficulties.

This article investigates research on the use of network-based three-dimensional virtual worlds in computer-assisted language learning (CALL). The significant features of the major types of virtual world currently utilized are examined, as are the hypothesized advantages and issues associated with their use. This is followed by a critical review…

The draw of simulations is that by replicating a simplified version of reality they can illustrate the repercussions that individual choices create. Students can play the role of a judge, an ambassador, or a parliamentarian and can experience first hand how their decisions play out. As a discipline, we assume that such practices are an improvement…

The use of cadavers to teach anatomy is well established, but limitations with this approach have led to the introduction of alternative teaching methods. One such method is the use of three-dimensional virtual reality computer models. An interactive, three-dimensional computer model of human forearm anterior compartment musculoskeletal anatomy…

In this paper, we take a designer's look at how the activities and data of learning and assessment can be structured in immersive virtual game environments called Massively Multi-Player Online Games (MMOG). In doing so, we examine the channels of evidence through which learning and assessment activities are derived in MMOGs, offering examples of…

The present study examines the effect of activating the connection between meaning and phonology in spelling exercises in second-grade spellers (n=41; 8 years and 3 months). In computer-based exercises in a within-subject design, semantic and neutral descriptions were contrasted and provided either before the process of spelling or in feedback.…

The purpose of this study was to investigate the effects of variations in text density levels and the cognitive style of field dependence on learning from a CBI tutorial, based on the dependent measures of achievement, reading comprehension, and reading rate, and of lesson completion time. Eighty college undergraduate students were randomly…

When it comes to technology, many schools know what they want. They want targeted and scalable solutions that enhance learning and meet the NETS.S. And the teachers in those schools want simple, strategic instructional frameworks for developing their students' basic and digital age skills while meeting diverse learning needs. But as many…

An online testing system developed for entry-skills testing of first-year university students in algebra and calculus is described. The system combines the open-source computer algebra system "Maxima" with computer scripts to parse student answers, which are entered using standard mathematical notation and conventions. The answers can…

This article describes the development of the spiritual fitness component of the Army's Comprehensive Soldier Fitness (CSF) program. Spirituality is defined in the human sense as the journey people take to discover and realize their essential selves and higher order aspirations. Several theoretically and empirically based reasons are articulated…

An embodied approach to reading comprehension suggests that emerging readers must learn to map words and phrases onto their remembered experiences, but this is made difficult by the necessity of focusing attention on decoding. Having children manipulate toys to correspond to what they are reading overcomes this problem, but introduces its own…
