computer-supported collaborative learning (cscl) is a new trend in educational sciences. this study investigates how knowledge sharing and transferring can be facilitated by using cscl in a problem-solving setting. intervention of research is education regarding sustainable water resources management (swrm) by computer-supported collaborative learning (cscl). the purpose of this research was to...

This paper evaluates a textbook called Traveller 4 that is used in the second grade of secondary schools Riyadh City, Saudi Arabia, considering its general appearance and design, objectives, content, social cultural contexts, tasks activities, usefulness for developing language skills. The also reviews literature concerning evaluation, referring to various theoretical empirical studies have con...

This study aimed at providing learners with an opportunity not only to bring together their core and disciplinary knowledge to acquire major skills of learning English as a foreign language (EFL), and the intellectual challenge of these issues at the interface of media, language and religion, but also help the materials generators to produce suitable types of content to be delivered through the...

In this paper, we combine existing NLP techniques with minimal supervision to build memory tips according to the keyword method, a well established mnemonic device for second language learning. We present what we believe to be the first extrinsic evaluation of a creative sentence generator on a vocabulary learning task. The results demonstrate that NLP techniques can effectively support the dev...

this study builds on laufer and hulstijn’s (2001) motivational-cognitive construct of task-induced involvement in learning vocabulary and addresses itself to its strong claim that the depth of processing is the overriding factor in learning words. the paper first re-examines the effect of processing load and then of task type on the initial learning and retention of words. to do so, 60 efl lear...

We discuss two NIST coordinated evaluations of automatic language recognition technology planned for calendar year 2015 along with possible additional plans for the future. The first is the Language Recognition i-Vector Machine Learning Challenge, largely modeled on the 2013-2014 Speaker Recognition i-Vector Machine Learning Challenge. This online challenge, emphasizing the language identificat...

In this paper we evaluate the Parallel-Horus parallelization strategy, and propose some approaches for further optimization. Also, we compare the Parallel-Horus approach with other strategies described in the literature. Furthermore, we investigate if adding automatic task parallelization is possible, and if this can be done in a user-transparent way.
