This paper introduces process modeling and mining as an approach to process analysis for CSCL. This approach is particularly relevant for collaborative learning that takes a project-based form, and is applied in this study to online chat data from teams working on a complex task. The groups differed in terms of the number of members and the amount of scaffolding aimed at group processes and tas...

Systematic phonics instruction in first language education has recently received considerable research attention due to its critical role in facilitating phonological awareness and processing skills. However, little is known about the effects of systematic phonics instruction on foreign language reading and spelling in an EFL context. This study examined the effects of spelling-based phonics in...

the purpose of this study was to investigate the effect of call/web-based instruction on improving efl learners’ pronunciation ability. to this end, 85 students who were enrolled in a language institute in rasht were selected as subjects. these students were given the oxford placement test in order to validate their proficiency levels. they were then divided into two groups of 30 and were rando...

A codesign approach for complex video compression systems is presented. The system is based on a exible and programmable VLIW (Very Long Instruction Word) architecture. The design approach can be subdivided into two phases: a quantitative analysis for deriving the main processor structure and a cosynthesis for generating the processor hardware and the compiler back-end. The analysis results of ...

The goal of this thesis is to explore how foreign language learning can be facilitated through the use of intelligent computer-assisted language learning (ICALL) based on natural language processing (NLP) methods. ICALL was provided in the form of a task-based dialog system that gives corrective feedback.We investigated how different parameters of the interaction affect the learning progress. B...

Online interactive exchange offers the learner many opportunities to use the target language to negotiate both meaning and form in a social context that is crucial for second language acquisition. This paper discusses a pilot study using synchronous electronic chats combined with task-based instruction (TBI) to enhance learners’ communication skills. TBI focuses on the two-way exchange of infor...
