This research assessed the value of case study methodology in the design of an educational computer simulation. Three sources of knowledge were compared to assess the value of case study: practitioner and programmer knowledge, disciplinary knowledge, and knowledge obtained from a case study of teacher practice. A retrospective analysis revealed…

This article describes a study that investigates learner responses to three distinct types of corrective feedback for misspellings produced by English learners of German. Twenty-eight beginner and intermediate students used an online parser-based system for German that recorded student interaction with the software over 15 weeks. The study…

In this paper we present eTeacher, an intelligent agent that provides personalized assistance to e-learning students. eTeacher observes a student's behavior while he/she is taking online courses and automatically builds the student's profile. This profile comprises the student's learning style and information about the student's performance, such…

The "quantum efficiency" (QE) is an important property of a light detector. This quantity can be determined in the undergraduate physics laboratory. The experimentally determined QE of a silicon photodiode appeared to be in reasonable agreement with expected values. The experiment confirms the quantum properties of light and seems to be a useful…

A number of educational researchers have developed pedagogical approaches that involve the teacher in discovering and helping to correct misconceptions that students bring to their study of their subject matter. During the last decade, several computer systems have been developed to support teaching and learning using this kind of approach. A…

An emerging trend in physical education curriculum has been sparked by the influx of a relatively new technology to the market referred to as Active Gaming or Exergaming. Exergaming has become a new buzzword identified by Popular Science as one of the ten new terms predicted to enter mainstream vocabulary in the next few years. Defined as video…

In this paper we present a system for automatic correction of errors made by learners of English. The system has two novel aspects. First, machine-learned classifiers trained on large amounts of native data and a very large language model are combined to optimize the precision of suggested corrections. Second, the user can access real-life web…

A crucial question for automatically analyzing learner language is to determine which grammatical information is relevant and useful for learner feedback. Based on knowledge about how learner language varies in its grammatical properties, we propose a framework for reusing analyses found in corpus annotation and illustrate its applicability to…

This study examined the tensions surrounding the implementation of a technology-rich educational innovation called Quest Atlantis (QA) in a local public elementary school. Three qualitative case studies of three classrooms implementing the innovation and a subsequent cross-case analysis were undertaken to illuminate: 1) the reasons why teachers…

Appropriate educational technologies have the potential to make physics' concepts more accessible through visualization, modeling and multiple representations. Students are engaged in more powerful scientific activities and they are able to perform investigations that would not be possible without the use of technology. This paper presents…

The use of the Web to deliver open, distance, and flexible learning has opened up the potential for social interaction and adaptive learning, but the usability, expressivity, and interoperability of the available tools leave much to be desired. This article explores these issues as they relate to teachers and learning designers through the case of…

Educational hypertexts usually include graphical overviews, conveying the structure of the text schematically with the aim of fostering comprehension. Despite the claims about their relevance, there is currently no consensus on the impact that hypertext overviews have on the reader's comprehension. In the present paper we have explored how…

One critical issue arising in the educational use of collaborative learning concerns the teacher's difficulty in evaluating the contribution and participation of each student in group-work. This article aims to illustrate and discuss a methodology that enables evaluation of the collaborative learning process based on co-writing in a wiki…

The changing nature of literacy is well documented within the literature, challenging educators to examine their pedagogies in light of the needs of learners in the current climate. The development and creation of non-linear texts within primary classrooms is of current interest as they reflect the types of texts accessed and created by users of…

Working as a legislative reference librarian at the Connecticut State Library exposes the author to many complex topics. Law, by nature, is a multidisciplinary field involving social issues and legal ramifications. Each year when the legislature is in session (January-June during even years, February-May during odd years), the Legislative Bill…
