the aim of this study was to determine adherence and attrition rates in a lifestyle intervention for people with metabolic syndrome.adherence and attrition data from a randomized controlled trial were collected. participants were classified as adherence group if they completed assessments at 3 and 6 months follow-up and as attrition group if they did not. physical activity and quality of life w...

computer-assisted language learning (call) is reaching an up most position in the pedagogical field of english as a second or foreign language (esl/efl). the present study was carried out to study the effect of using phonetic websites on iranian efl students’ pronunciation and knowledge of phonemic symbols. participants of the study included 30 efl female pre-intermediate students studying in k...

We present a detailed characterization of instruction cache performance for IBM’s J2EE-enabled web server, WebSphere Application Server (WAS). When running two J2EE benchmarks on WebSphere, we find that instruction cache misses cause a 12% performance penalty on current-generation Power5-based multiprocessor systems. To mitigate this performance loss, we describe a new call-chain based algorith...

This paper presents a proposal of a framework for the integration of web-based educational systems. It is part of an on-going research work (MEDEA project), whose final goal is to develop a general framework to build open Intelligent Tutoring Systems (ITS). We understand “open system” as a set of autonomous educational modules which communicate between themselves, following high-level pre-estab...

A novel application of web-based virtual laboratories to prepare students for physical experiments is explored in some detail. The pedagogy of supplementing physical laboratory with webbased virtual laboratories is implemented by developing a web-based tool, designated in this work as “eLIVE”, an acronym for Engineering Laboratory Instruction in Virtual Environment. Two physical experiments, on...

the present study investigated comparatively the impact of two types of input enhancement (i.e. textual vs. compound enhancement) on developing grammar ability in iranian efl setting. sixty-five female secondary high school students were selected as a homogenous sample out of about a 100-member population based on nelson language proficiency test. then, their grammar ability was measured based ...

This paper reports findings of a study that examined student performance and attitudes towards the use of information technology in virtual and conventional settings. Students were preservice undergraduate and graduate students enrolled in an educational media and technology course. All were fulltime, on-campus students, but one group completed the course entirely online. A Web-based survey was...

Personalization is a very crucial matter in Web-based educational systems, since these systems aim at reaching a large and heterogeneous group of learners in settings where no teacher may be available. The personalization needed in distance learning may be achieved by the integration of Intelligent Tutoring Systems with Web-based education. In this paper we describe an adaptive Web-based Algebr...
