Students seldom think about language unless they are instructed to do so or are made to do so during learning activities. To arouse students’ awareness while learning English for Specific Purposes (ESP), this study formed a computer-supported collaborative learning (CSCL) community to engage teachers and students from different domains and countries in intercultural communication. Participating...

This document describes a non-intrusive method for measuring one-way delay of IP packets. Furthermore it describes how to use NetFlow Version 9 to export the data of such measurements and evaluation processes.

This study explores the construct validity of speaking tasks included in the TOEFL iBT (e.g., integrated and independent speaking tasks). Specifically, advanced natural language processing (NLP) tools, MANOVA difference statistics, and discriminant function analyses (DFA) are used to assess the degree to which and in what ways responses to these tasks differ with regard to linguistic characteri...

The primary purpose of this study is to examine science student teachers' experience with educational technology, their intentions for their own use, their intentions for their students’ use, and their beliefs in the value of educational technology in science instruction. Four-hundred-forty-eight science student teachers of different disciplines and levels participated in the study. A questionn...

A general parameter process defined by a continuum of random variables is not jointly measurable with respect to the usual product σ-algebra. For the case of independent random variables, a one-way Fubini extension of the product space was constructed in [11] to satisfy a limited form of joint measurability. For the general case we show that this extension exists if and only if there is a count...

In any distance-education situation students and tutors are at a distance from each other at least in the sense that they are not in the same room while learning and teaching. This means that distance education relies on media. It has two constituent elements, on the one hand the presentation of learning matter, which can be described as one-way traffic, on the other hand interaction between st...
