Blended learning: an Asian tale

Over the past few years increasing online learning is part of the normal educational experience of students. This paper examines the changes faced by two universities in different countries as they move to blend traditional face-to-face learning activities with those online. In particular, it reviews lessons that can be drawn for others moving into blended learning environments for successful implementation

Usability of Web-based Knowledge Portals to support Research Organizations

Usability refers to the effectiveness, efficiency and user satisfaction of a designed product or system. One of the most of productive ways of measuring usability goals is through questionnaires and surveys. In this paper, we discuss usability related issues from a users’ perspective in the design analysis of a web-based knowledge portal that was developed to support the knowledge management activities of an educational research organization. The original portal system initially experienced high levels of user participation. However in recent times, this trend had been reversed with flagging log-in access rates. Consequently, a criterion-based usability survey instrument was designed and implemented online to gather users’ responses and comments. The survey outcomes indicated that a large number of respondents used the portal sporadically with a significant number being completely unaware of many of its services. Thus based upon this feedback, the existing portal was revamped to ensure a more user-centric design model that focused on the cornerstone aspects of user control, ease of navigation, personalization services and clarity in visual presentation of information.Usability refers to the effectiveness, efficiency and user satisfaction of a designed product or system.

Technologies and the representation of ideas

There is a change afoot and it might prove a pivotal point for the world of digital education. Technologies are more focussed on what the user wishes to achieve as an outcome, pedagogies are less focussed upon integration of ICTs and more on the need for the technologies to represent the information and knowledge of the discipline. We are moving into a time where the technology can assist us to represent ideas in a variety of forms, to share resources and to assist with the creation of a new forms of representation. Additionally as we employ collaborative tools and access the Internet, we can co-construct representations of our understandings about the world

Search for composite and exotic fermions at LEP 2

A search for unstable heavy fermions with the DELPHI detector at LEP is reported. Sequential and non-canonical leptons, as well as excited leptons and quarks, are considered. The data analysed correspond to an integrated luminosity of about 48 pb^{-1} at an e^+e^- centre-of-mass energy of 183 GeV and about 20 pb^{-1} equally shared between the centre-of-mass energies of 172 GeV and 161 GeV. The search for pair-produced new leptons establishes 95% confidence level mass limits in the region between 70 GeV/c^2 and 90 GeV/c^2, depending on the channel. The search for singly produced excited leptons and quarks establishes upper limits on the ratio of the coupling of the excited fermio

Energy dependence of Cronin momentum in saturation model for p+Ap+A and A+AA+A collisions

We calculate $\sqrt{s}$ dependence of Cronin momentum for $p+A$ and $A+A$ collisions in saturation model. We show that this dependence is consistent with expectation from formula which was obtained using simple dimentional consideration. This can be used to test validity of saturation model (and distinguish among its variants) and measure $x$ dependence of saturation momentum from experimental data.Comment: LaTeX2e, 12 pages, 8 figure
