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...

the present study aims to investigate the relative effectiveness of different types of pragmatic instruction including two collaborative translation tasks and two structured input tasks with and without explicit pragmatic instruction on the production of apologetic utterances by low-intermediate efl learners. one hundred and fifty university students in four experimental groups and one control ...

We investigate how supervision (in the form of explicit instruction) interacts with distributional learning in the acquisition of the perception of a novel vowel contrast in a second language. An experiment with non-Dutch-speaking Bulgarians reveals that listeners who receive bimodal distributional training without explicit instruction can acquire new Dutch vowel contrasts, and that listeners w...

With the aim of more emphasis on pragmatics and its inclusion in EFL classrooms, this study attempted to investigate the effectiveness of obtrusive and unobtrusive focus on form instructions on learners’ pragmatic performance of criticizing in English. 54 Iranian learners, all at intermediate level, participated in this study, and they were divided into three groups: 19 participants receiving o...

The problem we address is practical design of methods for users, especially relatively non-technical end users, to author rules that drive rule-based intelligent agents. We are concerned especially with networked applications of intelligent agents in the realm of information access, e.g., news, mail, Web pages, and the like. For these applications, an important value of intelligent agents is th...

The present study aimed to examine any possible relevance of perfectionism as a personal trait variable, in moderating the effectiveness of meta-cognitive instruction on bottom-up and top-down sub-processes of listening comprehension with a sample of EFL learners in Iranian context. To this end, 94 female EFL learners were selected from among 136 EFL learners at Andisheh Language Institute in M...

This paper mainly discussed the application of explicit instruction and implicit in second language teaching environment through comparison analysis. The discuss reason why is better than from two perspectives, first one direct instruction, error correction. Finally concluded that has more advantages suitable for teaching.

Homophonous verb forms are notoriously difficult to spell. Two intervention studies - one with secondary-school students and university compared the effectiveness of an Explicit Direct Instruction (EDI) teaching approach that was very interactive traditional instruction (TI) on Dutch homophonous spelling. The two approaches differ in attention dedicated identification grammatical functions teac...
