This study investigated the use of wikis for collaborative writing projects. Fourth- and sixth-semester German students wrote several of the regularly assigned essay topics during one semester in collaboration with another student using a wiki. Participants used a variety of strategies in the planning, writing and revision phases of their essays.…

Wikis, as one of the Web 2.0 social networking tools, have been increasingly integrated into second language (L2) instruction to promote collaborative writing. This paper reports on a case study involving 35 university students at the beginning level who contributed to wiki pages over a period of 14 weeks. The affordances and constraints of using…

This article discusses the development and functionalities of an intelligent computer-assisted language learning (ICALL) system. By way of example, we describe "E-Tutor", an ICALL system for L2 learners of German that has been in use for a decade. Based on advancements in technology, user studies with L2 learners of German as well as feedback…

In this paper we present a system for automatic correction of errors made by learners of English. The system has two novel aspects. First, machine-learned classifiers trained on large amounts of native data and a very large language model are combined to optimize the precision of suggested corrections. Second, the user can access real-life web…

In this article, we present an approach to the automatic correction of preposition errors in L2 English. Our system, based on a maximum entropy classifier, achieves average precision of 42% and recall of 35% on this task. The discussion of results obtained on correct and incorrect data aims to establish what characteristics of L2 writing prove…

This paper presents a new version of Robo-Sensei's NLP (Natural Language Processing) system which updates the version currently available as the software package "ROBO-SENSEI: Personal Japanese Tutor" (Nagata, 2004). Robo-Sensei's NLP system includes a lexicon, a morphological generator, a word segmentor, a morphological parser, a syntactic…

Error diagnosis in ICALL typically analyzes learner input in an attempt to abstract and identify indicators of the learner's (mis)conceptions of linguistic properties. For written input, this process usually starts with the identification of tokens that will serve as the atomic building blocks of the analysis. In this paper, we discuss the…

This paper presents a "didactic triangulation" strategy to cope with the problem of reliability of NLP applications for computer-assisted language learning (CALL) systems. It is based on the implementation of basic but well mastered NLP techniques and puts the emphasis on an adapted gearing between computable linguistic clues and didactic features…

This study explores the relationship between scrolling, negotiated interaction, and self-initiated self-repair (SISR) in a task-based synchronous computer-mediated communication (SCMC) foreign language learning environment. Pairs of adult learners of German engaged in four jigsaw tasks over the course of one university semester. Video screen…

Recasts are an important type of implicit negative feedback that has attracted much attention in both L1 research and SLA research. The utility of recasts in face-to-face interaction has been empirically established, and the contingency of recasts is argued to be the key. However, the efficacy of recasts in computer-mediated communication (CMC),…

This paper describes the development and evaluation of a handwritten correction support system with audio and playback strokes used to teach Japanese writing. The study examined whether audio and playback strokes have a positive effect on students using honorific expressions in Japanese writing. The results showed that error feedback with audio…

Faced with the need to teach English to a large number of students, the "Universidad de Concepcion," Chile, has created an innovative Communicative English Program using ICT, which is made up of four modules covered in four academic terms. The English program aims to develop integrated linguistic skills with a focus on learning for authentic…

This exploratory study examines corrective feedback in native speaker-nonnative speaker (NS-NNS) and NNS-NNS dyads while participants were engaged in communicative and problem-solving activities via "Yahoo! Instant Messenger" (YIM). As "negotiation of meaning" studies of the 1990s have shown, linguistic items which learners negotiate in…

Computer-mediated communication (CMC) forms an integral part of the first-year Spanish course, "Spanish Without Walls" (SWW), designed for distance education. The CMC component of SWW supports bimodal (i.e., oral and written) interactions among students and the instructor and provides the same kinds of benefits as those in face-to-face…

This paper investigates the impact that a teacher's virtual presence--or lack thereof--has on students' chat behavior with regard to error correction, uptake, target language use, and on-task behavior. The data come from beginning German students engaged in pair and small-group chatting activities at a major American university. Transcripts from…
