Not long ago, the authors participated in EDUCAUSE 2009 in Denver. Because they were delivering a presentation on instructional uses of Twitter, their ears and eyes were wide open for other presentations mentioning social networking in general and Twitter specifically. At a lively "debate", the negative commentary focused on three things: Twitter…

In this paper we consider prior definitions of the terms "ill-defined domain" and "ill-defined problem". We then present alternate definitions that better support research at the intersection of Artificial Intelligence and Education. In our view both problems and domains are ill-defined when essential concepts, relations, or criteria are un- or…

This article reports on the findings obtained from an exploratory study on the effectiveness of feedback in a computer-based learning environment. The main aim of the study was to gain insight into learning outcomes and student perceptions in relation to different types of feedback. This aim was operationalised in terms of an investigation amongst…

Technology is a natural part of education for all students across a variety of subjects, including mathematics, as educators work to prepare students for tomorrow's work force and align their curriculum and teaching with national standards such those developed by the National Council of Teachers of Mathematics (NCTM, 2000). This article reviews…

The Integrating Data Analysis (IDA) approach to undergraduate education developed by the American Sociological Association (ASA) and the Social Science Data Analysis Network (SSDAN) has been embedded in the undergraduate sociology curriculum at Lehman College, The City University of New York (CUNY), since 2003. This study draws on student and…

This paper reports the observations made and experience gained from developing and delivering an online quantitative methods course for Business undergraduates. Inspired by issues and challenges experienced in developing the online course, a model is advanced to address the question of how to guide the design, development, and delivery of…

Advances in computer and interface technologies have made it possible to create three-dimensional (3D) computerized models of anatomical structures for visualization, manipulation, and interaction in a virtual 3D environment. In the past few decades, a multitude of digital models have been developed to facilitate complex spatial learning of the…

Numerous studies have indicated that the provision of appropriate computer-mediated support to second language (L2) learners results in different vocabulary learning outcomes. However, there is no study available that investigates the transition in their way of learning vocabulary under the influence of technology-based support. This article…

"Present text accompanying pictures aurally to promote learning" is a well established principle of instructional design. But recently, it was shown that under certain conditions visual texts can be preferable. Instructional pacing seems to be one of these conditions that mediate effects. Especially, enabling learners to pace an…

In a series of three experimental studies, the effectiveness of three-dimensional computer simulations to aid the understanding of chemical structures and their properties was investigated. Arguments for the usefulness of three-dimensional simulations were derived from Mayer's generative theory of multimedia learning. Simulations might lead to a…

Graphing is a key skill in the study of Physics. Drawing and interpreting graphs play a key role in the understanding of science, while the lack of these has proved to be a handicap and a limiting factor in the learning of scientific concepts. It has been observed that despite the amount of previous graph-working experience, students of all ages…

Learning management systems (LMS) serve as the primary online technology for student learning in many universities. Although they are only one "solution", they are often regarded as all encompassing. How university teachers reconcile their beliefs about such technologies with their pedagogical beliefs remains a relatively unexplored…

This work reports on the construction of a rated database of spontaneous speech produced by second language (L2) learners of English. Spontaneous speech was collected from 28 L2 speakers representing six language backgrounds and five different proficiency levels. Speech was elicited using formats similar to that of the TOEFL iBT and the Speaking…

Results of a study designed to determine the effectiveness of implementing three-dimensional (3D) stereo images of a human skull in an undergraduate human anatomy online laboratory were gathered and analysed. Mental model theory and its applications to 3D relationships are discussed along with the research results. Quantitative results on 62 pairs…

This article describes the influence of tool and task design on student interaction in language learning at a distance. Interaction in a multimodal desktop video conferencing environment, FlashMeeting, is analyzed from an ecological perspective with two main foci: participation rates and conversational feedback strategies. The quantitative…
