In this paper, we give a detailed account of the design principles and construction of activities designed for learning about the relationships between position, velocity and acceleration, and corresponding kinematics graphs. Our approach is model-based, that is, it focuses attention on the idea that students constructed their own models--in the…

Communication of emotions is of crucial importance in music performance. Yet research has suggested that this skill is neglected in music education. This article presents and evaluates a computer program that automatically analyzes music performances and provides feedback to musicians in order to enhance their communication of emotions.

Furthermore, students' satisfaction ratings indicated that LearnStar reviews were more enjoyable and conducive to participation than traditional reviews.…

This note describes a method for evaluating the sums of the m -th powers of n consecutive terms of a general arithmetic sequence: { S[subscript m] = 0, 1, 2,...}. The method is based on the use of a differential operator that is repeatedly applied to a generating function. A known linear recurrence is then obtained and the m-th sum, S[subscript…

This article reports on our experiences in providing interoperability between the ARIADNE knowledge pool system (KPS) (Duval, Forte, Cardinaels, Verhoeven, Van Durm, Hendrickx et al., 2001) and several other heterogeneous learning object repositories and referatories.

When most academic technologists tackle computing, their time is occupied by laptops and servers--relatively small-scale stuff. A couple of blades here, a couple of blades there. Generally, even for network managers, the processing power rarely stacks up to anything awe-inspiring. Sometimes, however, computing can be bigger and broader than many…
