Many second language acquisition researchers (e.g., Doughty & Williams, 1998; R. Ellis, 2007; Long, 1996, 2007; Lyster, Lightbown, & Spada, 1999; Russell & Spada, 2006) have advocated the use of negative feedback to promote learner noticing of errors and the internalization of correct forms. At the same time, the true efficacy of this practice is…

People are generally skilled at using a confidence scale to rate the strength of their memories over a wide range. Specifically, low-confidence recognition decisions are often associated with close-to-chance accuracy, whereas high-confidence recognition decisions can be associated with close-to-perfect accuracy. However, using a 20-point rating…

The concept of fail-forward can be used as a teaching technique to motivate students to learn from their mistakes. For example, when students are allowed to re-work incorrect responses on a test for a partial grade they are failing-forward. In this paper we look at the effects of failing-forward on student effort in online learning environments.…

In order to explore effective ways to develop Chinese English learners' communicative competence, this study first briefly reviews the advantages of communicative language teaching (CLT) method which widely practiced in the Western countries and analyzes in details its obstacles in Chinese classroom context. Then it offers guidelines for…

The question of whether marking speed is related to marking accuracy is important for training examiners and planning realistic marking schedules. We explored marking speed in the context of a past examination for an international biology qualification for 14- to 16-year-olds. Forty-two markers with differing backgrounds experimentally marked 23…

Too many multiple-choice tests are administered without an evaluative component. Teachers often return student assessments or Scantron cards--computerized bubble forms--without review, assuming that the printing of the correct answer will suffice. However, a more constructivist approach to follow up multiple-choice tests can make for more…

To investigate the pedagogical effectiveness of oral corrective feedback (CF) on target language development, we conducted a meta-analysis that focused exclusively on 15 classroom-based studies (N = 827). The analysis was designed to investigate whether CF was effective in classroom settings and, if so, whether its effectiveness varied according…

This study surveys the opinions of both teachers and students involved in the Year 1 course "University English" in the Language Centre at City University of Hong Kong. The survey involved 265 students and 37 teachers. The issues studied were: 1.) How useful is peer and teacher feedback? 2.) How effective are direct vs. indirect…

Researchers in career and technical education often ignore more effective ways of reporting and treating missing data and instead implement traditional, but ineffective, missing data methods (Gemici, Rojewski, & Lee, 2012). The recent methodological, and even the non-methodological, literature has increasingly emphasized the importance of…

Pronunciation errors may be caused by several different deviations from the target, such as voicing, intonation, insertions or deletions of segments, or that the articulators are placed incorrectly. Computer-animated pronunciation teachers could potentially provide important assistance on correcting all these types of deviations, but they have an…

In this paper, we give two unexpected applications of a Hamming code. The first one, also known as the "Hat Problem," is based on the fact that a small portion of the available code words are actually used in a Hamming code. The second one is a magic trick based on the fact that a Hamming code is perfect for single-error correction.

This paper investigates the influence of three factors on pronunciation accuracy of Chinese adult foreign language learners. Ten target sounds including phonemes and syllables are included in the pre-test, an analysis of which shows that the mispronunciation of the randomly chosen target sounds mainly results from L1 negative transfer. It is…

Chinese Students' English has its own characteristics. It is of significance to analyze and study these characteristics. The paper uses the corpus approach to study the misuse of tenses in Chinese College students' CET-4 compositions of the sub-corpus of "Non-major College Students" in the Chinese Learner English Corpus (CLEC). Nine…

This study uses Monte Carlo simulations to demonstrate that regression-discontinuity designs arrive at biased estimates when attributes related to outcomes predict heaping in the running variable. After showing that our usual diagnostics are poorly suited to identifying this type of problem, we provide alternatives. We also demonstrate how the…

Poor performance on the antisaccade task has been proposed as a candidate endophenotype in schizophrenia. Caveats to this proposal, however, include inconsistent findings in first-degree relatives of individuals with schizophrenia, and substantial heterogeneity in individuals with the disorder. In this study, we examined antisaccade performance in…
