This paper analyses the role of Computer Algebra Systems (CAS) in a model of learning based on competences. The proposal is an e-learning model Linear Algebra course for Engineering, which includes the use of a CAS (Maxima) and focuses on problem solving. A reference model has been taken from the Spanish Open University. The proper use of CAS is…

This article deals with gender phenomena in the context of digital literacy. Studies show that computer use, computer skills, and computer-related self-concepts are subject to gender differences. These differences may affect classroom interactions as well as learning processes and have therefore to be considered carefully by teachers who apply…

In a recent meta-analysis of distance and online learning, Bernard et al. (2009) quantitatively verified the importance of three types of interaction: among students, between the instructor and students, and between students and course content. In this paper we explore these findings further, discuss methodological issues in research and suggest…

On-line college courses present a mandate for student identity verification for accreditation and funding sources. Student authentication requires course modification to detect fraud and misrepresentation of authorship in assignment submissions. The reality is that some college students cheat in face-to-face classrooms; however, the potential for…

The aim of the present study was to develop an on-line assessment system with constructed response items in the context of elementary mathematics curriculum. The system recorded the problem solving process of constructed response items and transfered the process to response codes for further analyses. An inference mechanism based on artificial…

This article presents an educational exercise in which statistical process control charts are constructed and used to identify the Steroids Era in American professional baseball. During this period (roughly 1993 until the present), numerous baseball players were alleged or proven to have used banned, performance-enhancing drugs. Also observed…

The increasing presence of multiple Information and Communication Technologies (ICT) in the classroom does not guarantee an improvement of the learning experiences of students, unless it is also accompanied by pedagogically effective orchestration of those technologies. In order to help teachers in this endeavour, it can be useful to understand…

This article presents findings from what we believe to be the first large-scale study of its kind on the use of ICT (information and communications technology) in English language classes in China. Participants are 400 EFL (English as a foreign language) teachers from different types of schools in Beijing. The purpose of the study was to examine…

In April 2006, Apple released a beta version of Boot Camp, a free software product that enables the installation of Windows XP (Home Edition or Professional with Service Pack 2) on an Intel-based Mac. (A beta version is not the final version, but it is ready for end users to try and test.) Essentially, Boot Camp splits your Mac into two hard…

Program animation systems have not been as widely adopted by computer science educators as we might expect from the firm belief that they can help in enhancing computer science education. One of the most notable obstacles to their adoption is the considerable effort that the production of program animations represents for the instructor. We…

While discussion of the criteria needed to assess learning objects has been extensive, a formal, systematic model for evaluation has yet to be thoroughly tested. The purpose of the following study was to develop and assess a multi-component model for evaluating learning objects. The Learning Object Evaluation Metric (LOEM) was developed from a…

New social-sharing applications are transforming the Internet from a "read-only" (Web 1.0) environment to a "read-write" ecology that many are calling Web 2.0. These tools (e.g., weblogs and wikis) enable Internet users to publish information online almost as easily as they can read online, and they have tremendous potential for learning. This…

These proceedings contain the papers and poster of the 6th International Conference on Educational Technologies 2019 (ICEduTech 2019), which has been organised by the International Association for Development of the Information Society and co-organised by the Lingnan University, in Hong Kong, February 8-10, 2019. ICEduTech is the scientific…

Professional astronomers use specialized software not normally available to students to determine the rotation periods of asteroids from fragmented light curve data. This paper describes a simple yet accurate method based on Microsoft Excel[R] that enables students to find periods in asteroid light curve and other discontinuous time series data of…

This article studies various holiday distributions, the most interesting one being Easter. Gauss' Easter algorithm and Microsoft Excel are used to determine that the Easter distribution can be closely approximated by the convolution of two well-known uniform distributions. (Contains 8 figures.)
