The imagination effect occurs when students learn better from imagining concepts and procedures rather than from studying them. Cognitive load theory explains the effect by better use of available working memory resources and increased productive, intrinsic cognitive load. The effect has been found in numerous empirical studies. However, in the…

As one type of the most extensively used sentences, English questions are must-learn grammatical structures for learners of English as a foreign language (EFL). However, it is commonly seen that English learners across proficiency levels produce ungrammatical English questions. To determine the source of learners' erroneous production, we…

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…

This article reports on two studies, testing how three different types of input (skewed first, skewed random and balanced) affect second language (L2) learning of English present counterfactual (IF-Is) and past counterfactual (IF-IIs) conditionals, two constructions differing in complexity. The experiment included a proficiency test, a pretest, a…

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…

Lexical inference through reading is considered an important method for vocabulary building; however, empirical research has not consistently offered strong evidence of the application of lexical inference in second language vocabulary learning. A recently burgeoning line of research focuses on second language (L2) lexical inference of compounds…

The present article argues for a conceptual distinction between corrective feedback and mediation that emphasizes the status of the latter not as an instructional practice but as a defining feature of human psychology (Vygotsky, 1987) that has direct implications for how instruction might be approached. Specifically, Sociocultural Theory (SCT)…

Knowledge of English affixes plays a significant role in increasing knowledge of words. However, few attempts have been made to create a valid and reliable measure of affix knowledge. The Word Part Levels Test (WPLT) was developed to measure three aspects of affix knowledge: form (recognition of written affix forms), meaning (knowledge of affix…

Most second language researchers agree that there is a role for corrective feedback in second language writing classes. However, many unanswered questions remain concerning the linguistic features to target and the type and amount of feedback to offer. This study examined essays by 151 learners of English as a second language (ESL), in order to…

This study explored the potential effects of communicative tasks developed using a reformulation of a task-based language teaching called Automatization in Communicative Contexts of Essential Speech Sequences (ACCESS) that includes automatization of language elements as one of its goals on learner attention to form in task-based interaction. The…

The purpose of this exploratory longitudinal study was to evaluate the efficacy of two new forms of recasts (i.e., elaborated and paraphrased recasts), each of which was designed to be more in accordance with contested views of input processing. The effectiveness of the two new forms of recasts was compared to that of conventional standard…

Previous research investigating the effectiveness of textual enhancement as a tool to draw adult second language (L2) learners' attention to the targeted linguistic form has consistently produced mixed results. This article examines how L2 form recognition and reading comprehension are affected by different types of textual enhancement.…

This quasi-experimental study investigated the noticeability and effectiveness of three corrective feedback (CF) techniques (recasts, prompts and a combination of the two) delivered in the language classroom. The participants were four groups of high-beginner college level francophone learners of English as a second language (ESL) (n = 99) and…

Drawing on longitudinal data, this study explores the dynamic relationship between the development of conceptual knowledge of language and the emergence of sociostylistic variation in second language (L2) speech. Participants include eight intermediate-level US university learners of French who participated in a concept-based pedagogical…

This paper presents the results of a parallel classroom experiment investigating the effects of processing instruction, traditional instruction and meaning-based output instruction on the acquisition of the English past simple tense. The subjects involved in the present studies were Chinese and Greek school-age learners of English residing in…
