Collocations are of great importance for second language learners, and a learner's knowledge of them plays a key role in producing language fluently (Nation, 2001: 323). In this article we describe and evaluate an innovative system that uses a Web-derived corpus and digital library software to produce a vast concordance and present it in a way…

Mobile devices could facilitate human interaction and access to knowledge resources anytime and anywhere. With respect to wide application possibilities of mobile learning, investigating learners' acceptance towards it is an essential issue. Based on activity theory approach, this research explores positive factors for the acceptance of m-learning…

Programs like PowerPoint and Keynote have become standard tools for teaching. Despite their ubiquity, an increasing number of educators blame them for both a deskilling of teachers and a dumbing down of students. This article examines some of the concerns that surround slideware-assisted teaching and offers guidelines and heuristics concerned…

Cloud computing is a technique for supplying computer facilities and providing access to software via the Internet. Cloud computing represents a contextual shift in how computers are provisioned and accessed. One of the defining characteristics of cloud software service is the transfer of control from the client domain to the service provider.…

This work is intended to describe a framework aimed to address the challenges in the development of mobile Collaborative Learning applications. Firstly, the paper offers an overview of some of the main principles of Collaborative Learning that will be the basis of the framework, which is based on three main pillars: collaboration and communication…

Since Java applets seem to be on the retreat in web application, other approaches for displaying interactive mathematics in the web browser are needed. One such alternative could be our open-source project JSXGraph. It is a cross-browser library for displaying interactive geometry, function plotting, graphs, and data visualization in a web…

Unexpected events often distract us. In the laboratory, novel auditory stimuli have been shown to capture attention away from a focal visual task and yield specific electrophysiological responses as well as a behavioral cost to performance. Distraction is thought to follow ineluctably from the sound's low probability of occurrence or, put more…

This study assessed whether two persons with multiple disabilities would be able to control environmental stimulation using body swing (changing standing posture) and a Wii Balance Board with a newly developed standing posture detection program (i.e. a new software program turns a Wii Balance Board into a precise standing posture detector). The…

Back in 2008, the authors were looking for a tool that would replace the library's Outlook folders and much of what the library had stored on shared network drives. So they were mainly looking for something that would hold their documents, allow them to better organize those documents, offer an easy way to search for those documents, and be easy…

Based on the demonstrated value of peer reviews in the engineering industry, numerous industry experts have listed it at the top of the list of desirable development practices. Experience has shown that problems (defects) are eliminated earlier if a development process incorporates peer reviews and that these reviews are as effective as or even…

ADCs (analog-to-digital converters), especially Pipeline and Sigma-Delta converters, are designed using complex architectures in order to increase their sampling rate and/or resolution. Consequently, the learning of ADC devices also encompasses complex concepts such as multistage synchronization, latency, oversampling, modulation, noise shaping,…

We describe the main features of a program written to perform electronic marking of quantitative or simple text questions. One of the main benefits is that it can check answers for being consistent with earlier errors, so can cope with a range of numerical questions. We summarise our experience of using it in a statistics course taught to 200…

The "p"-median clustering model represents a combinatorial approach to partition data sets into disjoint, nonhierarchical groups. Object classes are constructed around "exemplars", that is, manifest objects in the data set, with the remaining instances assigned to their closest cluster centers. Effective, state-of-the-art implementations of…

This article demonstrates how mind-mapping software can be used to help premedical students combine, learn, retain, apply and relate medical terminology sharing the same root/base, the same prefix or suffix, cognates, derivatives, singular and plural forms and relate details which radiate out from the centre. It shows how the mind-mapping software…

Students learn best when teachers get out of the way. Unfortunately, university classrooms continue to be intensely teacher-centric, are driven by the teacher's agenda and calendar, and embrace simple models rather than complex alternatives. These simple types of learning environments frustrate students' development of the risk-­taking and choice…
