recent years have witnessed an increased attention to form focused instruction and consciousness raising activities (ellis, 2002; doughty & williams, 1998) on the one hand and extensive and meaningful exposure to the target language (klapper & rees, 2003; day & bamford, 1998) on the other. due to significance attributed to above mentioned issues by scholars, this study attempted to bridge them ...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
background: falling has a great importance among the elderlies. even if no physical injury occurs, it can cause fear of fallingdown again and, consequently, reduce older adults’ activities. with regard to the prevalence of falling among older adults, its prevention is essential. therefore, the present study was aimed to define the effect of need-based education on prevention of older adults’ fa...
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
Many human activities follow a loosely defined script in which individuals assume roles. Encoding such scripts in a formal representation makes it possible to build systems that observe human activity in order to provide services. In this paper, we present a conceptual framework in which scripts for human activit y are described as scenarios composed of actors and objects within a network of si...
Engineering design is a kind of human activity that makes use of many different knowledge sources. Basically, this may be well-structured explicit, domain specific knowledge or tacit, implicit and experience-based knowledge. Both types of knowledge have their particular roles in design, and thus in knowledge-based design support systems. In this paper several issues concerning knowledge-based d...
knowledge is to be maintained and owned by all, then the relations between academic, Western or conventional mathematics and the different mathematical knowledges and practices of different groups and individuals have to be brought into dialogue with each other, to be connected and contextualised. By valuing different kinds of mathematics and ways of knowing (and doing) mathematics, different p...
This paper is a result of research activities within wearable communications carried out at the Ericsson Norway Applied research center in collaboration with the University of Oslo. The research activities are based on the conviction that the user and usability should be in focus. The research is grounded on a field study conducted to investigate a highly mobile activity, namely bike messenger ...
