Research addressing the effectiveness of feedback for learning has focused on many dimensions of feedback, including the timing (Kulik & Kulik, 1988), type (Mory, 2004), and amount of available information (Dempsey et. al, 1993). Much of the feedback research in education has tacitly assumed that the available information is perceived, and any…

Like any infrastructure technology, Virtual World (VW) platforms provide affordances that facilitate some activities and hinder others. Although it is theoretically possible for a VW platform to support all types of activities, designers make choices that lead technologies to be more or less suited for different learning objectives. Virtual World…

Second Life is a three-dimensional (3D) electronic environment where members can socialize, hold virtual meetings, or conduct economic transactions. Utilizing virtual environments like Second Life is believed to provide educators with a new medium for teaching and information dissemination that bypasses the normal boundaries associated with…

The increasing complexity of human body models enabled by advances in diagnostic imaging, computing, and growing knowledge calls for the development of a new generation of systems for intelligent exploration of these models. Here, we introduce a novel paradigm for the exploration of digital body models illustrating cerebral vasculature. It enables…

Learning embryology remains difficult, since it requires understanding of many complex phenomena. The temporal evolution of developmental events has classically been illustrated using cartoons, which create difficulty in linking spatial and temporal aspects, such correlation being the keystone of descriptive embryology. We synthesized the…

This paper describes a study aimed to identify most common impediments related to the introduction of an open-source mathematical software package GeoGebra. We report on the analysis of data collected during a three-week professional development programme organised for middle and high school teachers in Florida. The study identified challenges…

In this paper we report on the sustained research and development work at the AMSTEL Institute of the University of Amsterdam to improve mathematics and science education at primary and secondary school level, which has lead amongst other things to the development of the integrated computer working environment Coach 6. This environment consists of…

Pre-laboratory activities have been known to improve students' preparation before their practical work as they assist students to make available more working memory capacity for actual learning during the laboratory. The aim of this investigation was to compare two different teaching approaches which supported a pre-laboratory session by using the…

An Internet-based e-learning system offers many benefits over traditional learning environments. It provides a time, class size, and geographical location independent learning platform to students in addition to being able to consolidate e-learning content from a vast amount of Internet Web sites and deliver it to students. However, as the…

After the first observation of life under the microscope, it took two centuries of research before the "cell theory" was established. Luckily, today's teachers can take advantage of computer technology and speed up the discovery process in their classrooms. This article describes how computer-based instructional programs can be used to engage…

How can cognitive load in visual displays of computer simulations be optimized? Middle-school chemistry students (N = 257) learned with a simulation of the ideal gas law. Visual complexity was manipulated by separating the display of the simulations in two screens (low complexity) or presenting all information on one screen (high complexity). The…

The rapid acceleration of online course offerings presents a design challenge for instructors who want to take materials developed for face-to-face settings and adapt them for asynchronous online usage. Broadcast lectures are relatively easy to transfer, but adapting content is harder when classes use small-group discussions, as in role-playing or…

Spatial skills are known to vary widely among normal individuals. This project was designed to address whether these individual differences are differentially related to large-scale environmental learning from route (ground-level) and survey (aerial) perspectives. Participants learned two virtual environments (route and survey) with limited…

In the nineteenth century many people tried to seek a value for the most famous irrational number, [pi], by means of an experiment known as Buffon's needle, consisting of throwing randomly a needle onto a surface ruled with straight parallel lines. Here we propose to extend this experiment in order to evaluate other irrational numbers, such as…

Virtual reality (VR) that immerses users in a 3D environment through use of headwear, body suits, and data gloves has demonstrated effectiveness in technical and professional education. Immersive VR is highly engaging and appealing to technically skilled young Net Generation learners. However, technical difficulty and very high costs have kept…
