This paper explores the potentially powerful role e-assessment practices can have on culture change in learning and teaching. This paper demonstrates how new e-assessment practices can ‘push back’ through educational institutions. This is done by applying the work of Gibbs and Simpson (2004/5) to e-assessment practices. To illustrate the practical effects of this evidence-based framework, the a...
introduction : this in vitro study was designed to evaluate the effect of smear layer removal on push-out bond strength of white mineral trioxide aggregate (wmta) and calcium-enriched mixture cement (cem). materials and methods: dentin discs with 3 mm thicknesses were divided into 4 groups ( n =15): group 1: irrigation of the canal with normal saline and filling with wmta; group 2: irrigation w...
this article analyses the push and pull factors that bring visitors to the iranian national parks. the study used a structured questionnaire to collect data on these factors and the socio-demographic profile of the visitors. survey conducted in boujagh national park, an area of 3177 hectares located in the north of the iran, produced 400 questionnaires. the factor analysis identified four push ...
This paper explores the broad issues of why the meaningful use of ICT to engage in deep learning has not been widespread in K-12 schools. We argue a critical reason is the lack of sustainability in the implementation of ICT-enabled pedagogies in schools, arising from a failure to understand the conditions for systemic innovations. We describe the key issues related to sustainability from litera...
We present the architecture of UbiData an adaptable framework for mobile computing information dissemination systems. Applications built upon this framework communicate using dynamic channels, an information push model with extensions to capture mobilityspecific requirements. We also introduce the development process for UbiData’s applications.
We examine the effect of variability on the performance of an assembly system where two stations feed another station and a competing system where two independent stations are fed by a single station. We study the impact of variability in processing times, variability due to unreliable workstations, and variability due to imperfect yield. The above impact is examined for both PUSH and PULL manu...
