Introduces this special issue of the journal, which focuses on an important aspect of learner language--linguistic errors. Each of the nine articles are highlighted. (Author/VWL)

To overcome obstacles in error detection needed for intelligent feedback in computer assisted language learning (CALL), calls for a new focus on lexical items, both single words and multiword units of various types. Suggests single and multiword lexemes should not only be explicitly taught in CALL but could also provide the key to more effective…

Discusses selected theoretical aspects of providing error feedback for language learners. Theoretical considerations concerning the dialog with the learner about linguistic errors are discussed, and some conclusions for computer assisted language learning (CALL) system design are drawn. (Author/VWL)

Poses four important questions relevant to error diagnosis and correction in computer assisted language learning (CALL). These questions relate to the diagnosis of persistent second language (L2) learner grammar errors, whether these can be corrected, what types of feedback from the computer are most efficient for focusing the students' attention…

Presents four sets of natural language processing-based exercises for which error correction and feedback are produced by means of a rich database in which linguistic information is encoded either at the lexical or the grammatical level. (Author/VWL)

Reports a study on the impact of learner control on the error correction process within a web-based Intelligent Language Tutoring System (ILTS). During three 1-hour grammar practice sessions, 33 students used an ILTS for German that provided error-specific and individualized feedback. Results indicate the majority of students (85%) sought to…

This article discusses design and usability issues pertaining to context-sensitive "help" in computer-assisted language learning (CALL). As part of the discussion, we present a study in which we examined the effects of three independent factors on student usage of context-sensitive "help": feedback, exercise type, and language proficiency. Forty…

A convenient and user-friendly method for computer-based second-language instruction (especially exotic-alphabet languages) presents a "pool" of text chunks from which the student uses a mouse to select and drag the chunks to form answers. Several types of feedback, including edit markup, may be selected; revision consists of rearranging, adding,…

Zo eplicates in a synchronous learning environment a study that looked at the effectiveness of providing two types of corrective feedback to students in the classroom. Elementary learners of L2 English (N = 31) completed two communicative tasks, during which time they received either recasts (implicit feedback) or metalinguistic information…

Discusses how computer-assisted language learning programs can generate error messages to help students in different ways. The article points out that an easier solution is to program a computer to recognize several different kinds of generic errors not related to any particular question but applicable to many situations, in order to generate…

This study examined the relationship between discrimination error (determined by content analysis and tryout data) and confidence of response (determined by self report). Subjects were 63 undergraduate students enrolled in a biology class for nonmajors who received classroom expository information and read a text on the topic before they completed…

Describes a parser-driven Japanese tutor, "BANZAI," designed for second-language instruction and presents an empirical study of the program. Results indicate that ongoing rule-driven deductive feedback is more effective than example-driven inductive feedback for learning relatively complex structures whose grammatical rules are not…

A computer-based method of communicating syntactic knowledge to deaf students was designed, building on the visual orientation of deaf students and employing such American Sign Language techniques as visualization and directionality. The computer-based instructional treatments were presented as an educational game called the "Yes-No Game," with…

Describes theoretical and practical considerations related to the provision of feedback in the written compositions of advanced foreign language learners of French. Discusses the approach taken to teaching and assessing writing skills of students and considers how using a computer-based composition annotation program can contribute to reduction of…

Describes study of Army aviation students who were enrolled in training program that was designed to compare the effects of two strategies of error remediation during computer-based instruction (CBI). Treatments for the two experimental groups and a control group that had no CBI are described, and results of pretests and posttests are discussed.…
