This article presents a conceptual analysis of collaboration scripts used in face-to-face and computer-mediated collaborative learning. Collaboration scripts are scaffolds that aim to improve collaboration through structuring the interactive processes between two or more learning partners. Collaboration scripts consist of at least five components: (a) learning objectives, (b) type of activities...

Today's computer supported modelling environments could provide much more information about the users’ actions and problem solving processes than they usually store for later usage. Thus, relevant information about learning processes which could be used for reflection and analysis is lost. This paper describes an approach to tackle this issue by generating “reports”, in the sense of augmented s...

background: electronic learning (e-learning), is the use of electronic technology in education via computer and the internet. despite its slow adoption by faculty members, e-learning provides several benefits to individuals and organizations. this study was conducted to determine the factors influencing the adoption of e-learning by faculty members in tabriz university of medical sciences.    m...

this study investigated the effectiveness of explicit pragmatic instruction on the acquisition of requests by college-level english as foreign language (efl) learners in taiwan. the goal was to determine first whether the use of explicit pragmatic instruction had a positive effect on efl learners’ pragmatic competence. second, the relative effectiveness of presenting pragmatics through two deli...

this paper proposes an efficient tracking method for velocity control of an electro-hydraulic servo system (ehss) in the presence of flow nonlinearities and internal friction. the tracking method controller is a kind of feedback error learning structure. in the proposed method, the feedback error learning (fel) algorithm is used to control the velocity. there is no need to compute the system ja...
