the interaction of radiation with cells and tissues has a random nature. therefore, understanding the random nature of cell killing that is determined by poisson distribution statistics is an essential point in education of radiation biology. radbiostat is a newly developed educational matlab-based software designed for computer-assisted learning of the target theory in radiation biology. altho...

This study examined the effectiveness of Telegram social network on the writing performance of adult English as foreign language (EFL) learners at intermediate level. To achieve this, Oxford Quick Placement Test (2004) was administered to 46 EFL learners at Zaban-e No language institute in Talesh, Iran. Those who met the selection criterion, i.e., performed one standard deviation above and belo...

In communication learning by second language, three abilities have to be improved; listening, speaking and writing abilities. In this sense, it is important to evaluate user’s pronunciation ability and to detect mispronunciations in English CALL (Computer-Assisted Language Learning) systems. In this paper, we propose three functions (segmentation, phrasing and pronunciation evaluation) in the C...

The technology developed for task-based spoken dialogue systems (SDS) has a significant potential for Computer-Assisted Language Learning. Based on the CMU Let’s Go SDS, we describe two areas in which we investigated adaptations of the technology to non-native speakers: speech recognition and correction prompt generation. Although difficulties remain, particularly towards robust understanding, ...
