In this paper, we explore how the typical second year undergraduate topic of matrix diagonalisation can be applied to solve a geometric problem which arises frequently in Vector Calculus: to find the curve of intersection of a plane and a surface. We use GeoGebra, which offers a cost-free and dynamic interface, to explore a specific variant of…

Reading comprehension is key to knowledge acquisition and to reinforcing memory for previous information. While reading, a mental representation is constructed in the reader's mind. The mental model comprises the words in the text, the relations between the words, and inferences linking to concepts in prior knowledge. The automated model of…

In recent years, machine translation post-editing (MTPE or PE for short) has been steadily gaining ground in the language industry. However, studies that examine translators' perceptions of, and attitudes towards, MTPE paint a somewhat negative picture, with PE pricing methods and rates being a major source of dissatisfaction. While the European…

We describe a statistical seminar designed to provide a common foundation in core statistical concepts among all students as they enter a social work PhD program. Student feedback surveys assessed students' statistics preparation prior to entering the program, and pre- and posttests were compared for increases in statistical knowledge. Nearly half…

This paper presents Programming Adaptive Testing (PAT), a Web-based adaptive testing system for assessing students' programming knowledge. PAT was used in two high school programming classes by 73 students. The question bank of PAT is composed of 443 questions. A question is classified in one out of three difficulty levels. In PAT, the levels of…

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…

For competences development of learners and professionals, target competences and corresponding competence development opportunities have to be identified. Personal Recommender Systems (PRS) provide personal recommendations for learners aimed at finding and selecting learning activities that best match their needs. This article argues that a…

The authors teach upper-level science courses in cell biology, genetics, and biochemistry at a public, four-year "community university" that serves a demographically diverse population of traditional and nontraditional students. In this article, they describe some of the issues they have found to be particularly significant at their "community…

Data-logging exercises in science classrooms assume that with the proper scaffolding and provision of contexts by instructors, pupils are able to meaningfully comprehend the experimental variables under investigation. From a case study of knowing and learning in a fish hatchery using real-time computer statistical software, we show that…

This paper describes how the Multi-Attribute Utility Theory can be combined with adaptive techniques to improve individualised teaching in an Intelligent Learning Environment (ILE). The ILE is called Web F-SMILE, it operates over the Web and is meant to help novice users learn basic skills of computer use. Tutoring is dynamically adapted to the…

This article is about a computer lab project in which prospective teachers used Geometer's Sketchpad software to create two-dimensional nets for three-dimensional shapes. Since this software package does not contain ready-made tools for creating non-regular or regular polygons, the students used prior knowledge and geometric facts to create their…

Interactive multimedia programs have found their way into the hands of young children. This case study attempts to determine how two year old children interact with interactive multimedia technology, and addresses the following questions: is it appropriate to include the interactive multimedia technology in the same context as other objects like…

Examines assumptions inherent in open-ended learning; describes features of open-ended learning environments; and discusses implications for research, development, and implementation of open-ended learning systems. Highlights include context and experience; learner control; higher-order cognitive skills; understanding versus knowing; orienting…

Job advertisements listed in "American Libraries" and "Library Hotline" from January 1993 to January 1997 and archived through the Hypertext Archives for LIBJOBS from August 1995 to January 1997 were examined to determine the job opportunities and qualifications for systems librarians. The job opportunities were analyzed in…

Presents a sampling of questions from a districtwide survey that was designed to determine elementary and secondary school librarians' prior knowledge about and use of computers and software; what software and hardware was available at each school and how it was used; training needs; and the interpretation of policies on purchasing.
