CAL and FE: A Welsh perspective

The core of this paper is the result of an investigation into the use of computer‐aided learning (CAL) in further education (FE) colleges in Wales: All institutions surveyed used CAL to some extent in teaching or learning, and academic staff were in some way involved in producing CAL materials in almost all. However, student numbers were found not to be a good indicator of the degree to which CAL is used Furthermore, only two‐thirds of colleges approached claimed to have received any external funding for CAL and distance learning involved only a small proportion of FE students. Nevertheless, the general conclusion drawn is that all FE colleges in Wales use ICTs (information and communication technologies) extensively, although there are significant differences in the equipment/student ratios, and there appears to be little strategic college‐wide planning concerning such developments

Developing cross‐cultural communicative competence via computer‐assisted language learning: The case of pre‐service ESL/EFL teachers

Based on a qualitative research project, this article presents a view on the use of computer technology to develop a critical cross‐cultural communicative competence in English as a Second Language (ESL) / English as a Foreign Language (EFL) for pre‐service teachers. The article includes a brief critical theoretical framework, some classroom pedagogical implications, and a data‐based discussion of pre‐service teachers’ views. These views included: (1) critical views and an awareness of cultural power relations in computer‐assisted language learning (CALL), (2) uncritical views and a lack of awareness of cultural power relations in CALL, and (3) uses of metaphors in CALL. The powerful contribution of CALL can be found in its potential for providing ways to connect people and build communities, for offering opportunities for cross‐cultural communicative competence to be developed and used, and for improving processes of democratization via computer‐mediated communication. However, a socio‐cultural criticism revealed that this powerful tool, like any other media, is non‐neutral because it can serve to reinforce further the hegemonic aspects of education, that is, the dominant culture will be strengthened and protected via computer technology. Computer‐based technologies and software are increasingly incorporated into the curricula of ESLIEFL teacher education programmes. However, this integration is often done in ways that seem to leave unquestioned the potential cultural and hegemonic ramifications of such technology. Hence there is a need for a more critical technological competence

Technology Policy, Gender, and Cyberspace

Event based sampling occurs when the time instants are measured everytime the amplitude passes certain pre-defined levels. This is in contrast with classical signal processing where the amplitude is measured at regular time intervals. The signal processing problem is to separate the signal component from noise in both amplitude and time domains. Event based sampling occurs in a variety of applications. The purpose here is to explain the new types of signal processing problems that occur, and identify the need for processing in both the time and event domains. We focus on rotating axles, where amplitude disturbances are caused by vibrations and time disturbances from measurement equipment. As one application, we examine tire pressure monitoring in cars where suppression of time disturbance is of utmost importance

Differences in intention to use educational RSS feeds between Lebanese and British students: A multi‑group analysis based on the technology acceptance model

Really Simple Syndication (RSS) offers a means for university students to receive timely updates from virtual learning environments. However, despite its utility, only 21% of home students surveyed at a university in Lebanon claim to have ever used the technology. To investigate whether national culture could be an influence on intention to use RSS, the survey was extended to British students in the UK. Using the Technology Adoption Model (TAM) as a research framework, 437 students responded to a questionnaire containing four constructs: behavioral intention to use; attitude towards benefit; perceived usefulness; and perceived ease of use. Principle components analysis and structural equation modelling were used to explore the psychometric qualities and utility of TAM in both contexts. The results show that adoption was significantly higher, but also modest, in the British context at 36%. Configural and metric invariance were fully supported, while scalar and factorial invariance were partially supported. Further analysis shows significant differences between perceived usefulness and perceived ease of use across the two contexts studied. Therefore, it is recommended that faculty demonstrate to students how educational RSS feeds can be used effectively to increase awareness and emphasize usefulness in both contexts
