Serious games open up many new opportunities for complex skills learning in higher education. The inherent complexity of such games, though, requires large efforts for their development. This paper presents a framework for serious game design, which aims to reduce the design complexity at conceptual, technical and practical levels. The approach…

We studied students' conceptions of correctness and their influence on students' correctness-related practices by examining how 159 students had analyzed the correctness of error-free and erroneous algorithms and by interviewing seven students regarding their work. We found that students conceptualized program correctness as the sum of the…

The rapid increase in demand for American Sign Language (ASL) instruction between 1998 and 2002 created pervasive challenges in effectively assessing and documenting ASL learner performance. To address these challenges, we designed and developed the "Avenue ASL" e-assessment environment: an integrated, network-based software system to capture,…

We discuss the introduction and teaching of partial differential equations (heat and wave equations) via modeling physical phenomena, using a new approach that encompasses constructing difference equations and implementing these in a spreadsheet, numerically solving the partial differential equations using the numerical differential equation…

This correlational study examined the relationship between gender and the students' attitude and prior knowledge of using one of the mathematical software programs (MATLAB). Participants were selected from one community college, one state university and one private college. Students were volunteers from three Calculus I classrooms (one class from…

This study documents problem solving approaches that high school students develop as a result of using systematically Cabri-Geometry software. Results show that the use of the software becomes an important tool for students to construct dynamic representations of the problems that were used to identify and examine different mathematical relations.…

This study explores students' attitudes to the provision of formative feedback on academic work using audio files together with the ways in which students implement such feedback within their learning. Fifteen students received audio file feedback on written work and were subsequently interviewed regarding their utilisation of that feedback within…

Researchers increasingly suggest that accessibility remains a prominent issue across the World Wide Web (www). This study raises awareness about issues of access in higher education. This qualitative research design utilized a listserv that invited university based webmasters to use freeware to evaluate the overall accessibility of their…

We analyse the stability of the spring inverted pendulum with the vertical oscillations of the suspension point. An important factor in the stability analysis is the interaction between radial and oscillating modes. In addition to the small oscillations near the upper position, the nonlinearity of the problem leads to the appearance of limit-cycle…

This article presents the results of a comprehensive survey of integrated library system (ILS) vendors conducted by the author and commissioned by "Computers in Libraries" CIL. The survey was intended to: (1) provide an up-to-date comparison of functionality currently available in ILS products; (2) provide a comparison of support services…

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…

Catawba Valley Community College has introduced digital storytelling (DS), an innovative instructional method that has produced extraordinary results. Digital storytelling uses affordable software to craft powerful multimedia presentations of student writing. Students create 3-to-4-minute movies with images, voiceovers, and music. This project…

We observe that recruitment efforts aimed at alleviating the shortage of skilled workforce in computer engineering must be augmented with strategies for retaining and motivating the students after they have enrolled in our educational programmes. At the University of California, Santa Barbara, we have taken a first step in this direction by…

Design patterns have become a widely acknowledged software engineering practice and therefore have been incorporated in the curricula of most computer science departments. This paper presents an observational study on students' ability to understand and apply design patterns. Within the context of a postgraduate software engineering course,…

The form factors of handheld computers make them increasingly popular among K-12 educators. Although some compelling examples of educational software for handhelds exist, we believe that the potential of this platform are just being discovered. This paper reviews innovative applications for mobile computing for both education and entertainment…
