The purpose of this study was to investigate the 'locality' of the relationship between attitudes towards science, self-beliefs and science achievement for senior high school students in Australia, Cyprus and the USA. These relationships were examined with the use of the structural equation modeling software, AMOS. The data for this study were…

In this paper it is presented a virtual organizational environment, conceived with the integration of three computer programs: a manufacturing simulation package, an automation of businesses processes (workflows), and business intelligence (Balanced Scorecard) software. It was created as a supporting tool for teaching IE, its purpose is to give…

Privacy is a requirement that has not received the required attention in most e-learning platforms. Based on the results of a survey we identified weaknesses of e-learning platforms and describe improvements we made in Moodle as a proof-of-concept.

Computing limits of functions is a traditional part of mathematical analysis which is very difficult for students. Now an algorithm for the elimination of quantifiers in the field of real numbers is implemented in the program Mathematica. This offers a non-traditional view on this classical theme. (Contains 1 table.)

This paper reports on a design experiment in the domain of number sequences conducted in the course of the "WebLabs" project. We iteratively designed and tested a set of activities and tools in which 10-14 year old students used the "ToonTalk" programming environment to construct models of sequences and series, and then shared…

In this paper we consider geometrical construction problems and their role in mathematical education. Owing to the main features of construction problems (accuracy in making conclusions, strict structure, rigorous language and constructivistic nature), they can be fruitfully used in teaching mathematics and computer science. We shall try to shed…

This article describes possibilities for technology use among students with mild disabilities. It considers characteristics of assistive technology from the standpoint of strategies associated with universal design for learning and Type I and Type II software applications. After a brief description of assistive technology definitions, legislation,…

Background: Computer software is widely used to support literacy learning. There are few randomised trials to support its effectiveness. Therefore, there is an urgent need to rigorously evaluate computer software that supports literacy learning. Methods: We undertook a pragmatic randomised controlled trial among pupils aged 11-12 within a single…

This paper concerns the use of Information and Communications Technology (ICT) in music classrooms, with the focus on the secondary school music curriculum in the United Kingdom. In particular, it reports on a study of learners in a UK school using software designed to support practical music skills. The paper begins by briefly raising and…

Finite mixture models are well known to have poorly behaved likelihood functions featuring singularities and multiple optima. Growth mixture models may suffer from fewer of these problems, potentially benefiting from the structure imposed on the estimated class means and covariances by the specified growth model. As demonstrated here, however,…

In the last years, Instructional Design has seen the development of visual notation systems for supporting and enhancing the design process. Some of them concern the definition of learning goals, while others address the definition of learning activities or learning materials. These tools supposedly reduce the cognitive load and enhance design…

Concept mapping is a powerful learning technique that can be enhanced by computer technology. Software tools are already available for the preparation of concept maps but as yet, few systems provide feedback on their content. The claim made by this article is that by enlisting the student as an assessment partner, computer-based feedback becomes…

Computer-assisted assessment (CAA) has become increasingly important in education in recent years. A variety of computer software systems have been developed to help assess the performance of students at various levels. However, such systems are primarily designed to provide objective assessment of students and analysis of test items, and focus…

In spring 2003, the Distance Education Network (DEN), Viterbi School of Engineering at the University of Southern California (USC), had 860 students and more than 1,000 enrollments in 70 courses toward 10 different degrees. Typically, for assignments in engineering courses, professors require students to show how their answers are derived so that…

Tandem language learning occurs when two learners of different native languages work together to help each other learn the other language. First used in face-to-face contexts, Tandem is now increasingly being used by language-learning partners located in different countries who are linked via various forms of electronic communication, a context…
