The goal of the present set of experiments was to identify the conditions under which readers evoked prepotent-response inhibition to prevent interference from reactivated misconceptions. In Experiment 1, participants with varying inhibition ability read refutation texts that addressed common misconceptions and control texts. Overall, participants…

This article reports a classroom-based study of the effects of two types of corrective feedback (CF) on the acquisition of 3rd person "-s." One hundred and nine Chinese university students completed three communicative tasks: One group received implicit CF consisting of a single corrective move (implicit recasts), a second group received…

The current study investigated whether there exists a differential effect of direct and indirect corrective feedback (CF) on the acquisition of rule-based features (simple present) and item-based features (prepositions). Fifty students enrolled in an EFL writing class were divided into four groups. Each group received one of the following…

This study investigates whether gesture-enhanced recasts lead to better production of the English regular past tense. Fifty-nine low-intermediate ESL students at a US university took part in communicative activities in class, during which they received, respectively, no feedback, verbal recasts, or gesture-enhanced recasts, the latter being a…

This study aimed to investigate the effects of the integration of indirect feedback and concordances on improving grammatical accuracy in Thai EFL undergraduate students' writing and to explore the students' perceptions toward the intervention. Thirty third-year undergraduate students who studied at a government university in Bangkok were the…

This study explored the relative effect of recasts on second language (L2) Korean learners' accuracy development of the object relative clauses (RCs) and the honorific subject-verb (S-V) agreement in Korean and its relationship with language analytic ability (LAA). Forty-five L2 Korean learners participated in the study and five Korean native…

This quasi-experimental study, using a pretest-treatment-posttest-delayed posttest design, investigated the effects of two comprehensive corrective feedback strategies: direct corrective feedback (DCF), and metalinguistic explanation (ME) on L2 learners' written syntactic accuracy. The participants were 90 Turkish EFL learners. After ensuring…

The study investigated the interaction patterns of six ASEAN EFL university students when they worked in small groups on two collaborative writing tasks: a descriptive essay and an argumentative essay. Both groups were homogeneous in terms of gender and heterogeneous in terms of home countries. Data collection included pre- and posttest writing,…

Experts generally believe that written corrective feedback (CF) positively affects writing quality and learners' accurate use of language. However, researchers have not yet identified the most effective type of written CF or sufficiently explored the relation between type of written CF and targeted linguistic category. Thus, this study…

This study examines the effects of mixed oral corrective feedback (CF) on L2 learners' oral production accuracy. Twenty-four EFL learners from two intact classes in a Turkish university participated in the study. The two classes were randomly assigned to be an experimental and a control group and completed five communicative tasks. The learners in…

The study investigates to what extent English as a second language (ESL) learners develop explicit and automatised explicit knowledge of two target-forms (third person singular 's' and future conditional if-clause) after input and output based instruction and whether learning effects differ depending on the target forms. The study follows a…

Adopting the approaches of "pattern hunting" and "pattern refining" (Kennedy & Miceli, 2001, 2010, 2017), this study investigates how seven freshman English students from Taiwan used the Corpus of Contemporary American English to discover collocation patterns for 30 near-synonymous change-of-state verbs and new ideas about…

This study explored whether form-focused instruction (FFI) and peer corrective feedback (CF) facilitated vocabulary development during peer interaction (PI). Third-semester learners of German were assigned to a PI group (peer interaction only), PI FFI group (peer interaction and form-focused instruction), or PI FFI CF group (peer interaction,…

Three groups of EFL freshman students were concurrently enrolled in a grammar and a writing course. One group was taught the grammar and writing courses by the same instructor; the other two groups were taught grammar and writing by two different instructors using the same textbook but different instructional and assessment techniques. The study…

An earlier investigation found that the performance of advanced students in a quantum mechanics course did not automatically improve from midterm to final exam on identical problems even when they were provided the correct solutions and their own graded exams. Here, we describe a study, which extended over four years, in which upper-level…
