Reviews research on the effectiveness of recasts in first and second language acquisition, paying particular attention to how recasts have been defined and how their impact has been assessed in observational and experimental studies. Concludes that recasts appear to be most effective in contexts where it is clear to the learner that the recast is…

The history of mathematics is full of rich examples that can help students to see the place of the discipline within our cultural heritage. Valuable as this can be, it also has the unfortunate side-effect of making students think that all the math has already been done and they do not get a sense that the subject is dynamic and growing.…

This article offers an analysis of the process of error recovery as observed in the development and use of collections databases in a university museum. It presents results from a longitudinal case study of the development of collaborative systems and practices designed to reduce the number of errors found in the museum's databases as museum…

This paper presents comments on the article by D. Westen and J. Weinberger, which stated that '...science can be viewed as the history of confirmatory biases" (p. 609). This comment's authors prefer an alternative formulation: The history of science can be viewed as a constant and largely successful struggle to overcome confirmatory biases.…

The correction for attenuation due to measurement error (CAME) has received many historical criticisms, most of which can be traced to the limited ability to use CAME inferentially. Past attempts to determine confidence intervals for CAME are summarized and their limitations discussed. The author suggests that inference requires confidence sets…

Comments on the response offered by Cheng and Novick to White's initial comments on Cheng's and Cheng and Novick's previous articles. White asks if regularity information necessary for causal learning. He and Cheng and Novick agree that the causal relation is understood as a generative relation, but disagree on how this understanding comes about.…

Recasts have figured prominently in recent SLA research, with studies documenting significant advantages for learners exposed to this type of negative feedback. Although some researchers have suggested that such findings imply a beneficial role for negative evidence (i.e., information regarding the impossibility of certain utterances in the…

The study investigated EFL students' ability to comprehend and analyze advertisements and identify their stylistic features. Results of a test with sixty six EFL college students showed lexical and structural features that are easy to identify and those that are difficult to identify. Responses also reflected the difficulty level of the lexical…

This article presents a survey of computer-based tracking in CALL and the uses to which the analysis of tracking data can be put to address questions in CALL in particular and second language acquisition (SLA) in general. Adopting both quantitative and qualitative methods, researchers have found that students often use software in unexpected ways,…

Students were trained to perceive filled pauses (FP) as a bad speech habit. In a series of classroom sensitivity training activities, followed by students being rewarded to observe twenty minutes of live television from the public media, no differences between male and female Business Communication students was revealed. The practice of teaching…

The purposes of the current study were to (1) determine the relationship between the number of practice strategies students could articulate and their performance improvement scores, (2) identify trends in students' 5-minute practice behaviors, and (3) compare students' achievement based on their practice procedures. Participants were 65 eighth…

Since students enter college with a basic knowledge of the mechanics of writing, including grammar, spelling, and punctuation, most student writing mistakes amount to a failure to see what they have actually written. Thus, instructors must help students to apply knowledge they already have and to see their own errors through careful proofreading.…

This paper addresses the question of how grammar checkers may help or hinder students by analyzing the performance of the Microsoft Word 97's Grammar Checker at flagging and explaining errors frequently made by college students. Thousands of sentences were fed into the program. Results indicate that it caught some of the errors reliably (e.g.…

This study identified and described the ways in which negative evidence was made available and accessible to learners during two widely practiced classroom activities. One was a teacher-led discussion that emphasized communication of subject matter content. The other was a teacher-led sentence construction exercise that focused on application of…

For the purposes of this paper, proofreading will be defined as the final step of revising a paper. The paper describes what one writing lab, the Writing Center at the University of Connecticut, does to provide students with one-to-one help with their writing. It explains that services in the center include individual tutorials, a grammar hotline,…
