Simulations on computers can allow many experiments to be conducted quickly to help students develop an understanding of statistical topics. We used a simulation of a challenging problem in statistics as the focus of an exploration of situations where members of a problem-solving group are physically separated then reconnected via combinations of…

The Educational Object Economy (EOE) emerged from research on end-user authoring tools for multimedia software and, by 1997, developed into a library of over 2000 freely available interactive simulations for learning. The organization's original goals and its ongoing interest in alternative methods of software authoring led to continuing…

Facts, or skills? Content, or process? Teachers of history and social studies teachers often lock horns over these questions, trying to define the nature of their field and its role in secondary education. Teachers of history often focus on content, presenting the past as a series of important people and events, an accumulated cultural lore that…

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…

This article describes a project in which certain key concepts in probability were explored using graphics calculators with year 10 students. The lessons were conducted in the regular classroom where students were provided with a Casio CFX 9850 GB PLUS graphics calculator with which they were familiar from year 9. The participants in the…

The purpose of this study was to examine the effect of a Socratic animated agent on user performance in a computer-based CD player disassembly simulation. Vocational Education students were randomly assigned to one of two versions of the simulation. One version offered text-based feedback in the form of statements; the other one featured an…

A real-life analytical assignment is presented to students, who had to examine an air conditioning coolant solution for metal contamination using an atomic absorption spectroscopy (AAS). This hands-on access to a real problem exposed the undergraduate students to the mechanism of AAS, and promoted participation in a simulated industrial activity.

Purpose: The aim of this work is to implement bootstrapping methods into software tools, based on Java. Design/methodology/approach: This paper presents a category of software e-tools aimed at simulating laboratory works and experiments. Findings: Both students and teaching staff use traditional statistical methods to infer the truth from sample…

Virtual flight can be very entertaining, and computer-based simulators can also be educational, if organized and used correctly. When Berea College decided to find a flight simulator suited to the school's educational goals, the faculty settled on an ANT-18 Link trainer. This article begins with a discussion of Link trainers' history, and then…

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…

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…
