Concepts in fields such as astronomy often invoke scales of space and time that far exceed any that are perceived in daily life. Consequently, learners sometimes develop inappropriate intuitions of scale that in turn impede an understanding of related ideas. We investigate whether exposure to virtual 3D simulations of the solar system advances students’ understanding of phenomena for which misc...

English language teaching (ELT) writing practitioners have long attempted to improve EFL/ESL learners’ competence in writing with recourse to either instruction or feedback. Likewise, researchers have, to date, mainly focused on either of these treatments to enhance language learners’ composing ability. Which treatment leads to more significant improvements is, however, unclear. Moreover, of th...

This study investigated the effects of planned focus-on-form instruction (pFFI) on developing oral grammatical accuracy in Iranian English EFL learners. To this end, 60 lower-intermediate EFL learners studying English in a private English language institute in Tehran, Iran, were randomly assigned to two classes. Both classes received a task-based instruction on grammatical points elicited in or...

Class attendance of computer science courses in higher education is typically not overwhelming. Anecdotal reports and the authors’ experiences with a low-resource mode of peer instruction indicated increased class attendance after a lecture with such concept tests. This has been evaluated systematically with a 3-year computer science module using a medium-resource, software-based, Audience Resp...

Web-based learning environments, such as eLearning and distance learning systems, have become more common and popular in commercial and educational settings. They constitute a growing business today, and the concept of learning ‘anywhere, anytime’ has received much attention. These systems are still in their infancy, however, and are faced with various challenges to become fully effective tools...

This study explored the effectiveness of an inquiry-based cellulase laboratory unit in promoting inquiry in undergraduate students in biotechnology. The following tools were used to assess the students’ achievements and attitude: conceptual understanding test, concept mapping, students’ documents, CLES questionnaire, students’ self reflection, and interviews. Judging from their conceptual under...

Design of a programmable Multi core processor to implement compute several complex multimedia applications is presented. The Processor is expected to complete the given task with minimum latency. The hardware must adhere to minimal area and power requirements. This paper gives design details for enhancement of performance parameters of multi core processors. It is necessary to optimize the proc...

The uses of Internet technology within educational settings reflect particular perspectives on a host of issues including ability, race, and learning styles, but are often not examined for their implicit ideological or epistemological foundations. Web accessibility (ensuring that web content is accessible to persons with disabilities), though laden with progressive intent, is increasingly conne...

Software testing is presented as a so-called theme within which different authors and groups have defined different subjects each of these subjects having a different focus on testing. A uniform concept of software testing is non-existent and the space of possible coherent perspectives on software testing, each fitting within the theme, is viewed as being spanned by five dimensions, each dimens...
