Instructional videos for teaching second language (L2) vocabulary often feature an instructor onscreen. The instructor in the video may involuntarily produce beat gestures with their hands, as occurs in real teaching settings. Beat gestures highlight key information in speech by conveying the rhythm of the language, but do not themselves convey…

We investigated the effectiveness of two different teaching methods based on two different theoretical views of how languages are learned in oral proficiency after three years of L2 French instruction. The first method is commonly used in the Netherlands and is in line with structure-based (SB) principles, viewing language as a set of grammar…

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 article offers a methodological synthesis spanning 35 years of instructed second language acquisition research on the efficacy of form-focused instruction. Eighty-eight (quasi-) experimental studies were sampled from six academic journals: "Applied Linguistics," "Language Learning," "Language Teaching Research,"…

This study investigates the effects of input-based and output-based instructions on the acquisition of second language (L2) request modifiers. Four intact classes were randomly assigned to textual enhancement (TE), input flooding (IF), output-based instruction (OI), and control (CO) groups. The TE group watched some captioned videos on requests…

Learners entering higher education may learn specialized vocabulary of new disciplines in their second language (L2) with or without support from their first language (L1). However, these learners cannot rely on an established conceptual representation in L1 when learning L2 specialized vocabulary. The effects of learning a new concept in L1 prior…

This study employs eye-tracking to investigate how first (L1) and second language (L2) glosses affect lexical uptake and reading behaviors in L2 learners of English. The study also explores the relationship between lexical uptake and reading behaviors as a function of gloss type. To investigate this, 81 Korean university students were asked to…

This article reports on an experimental study that set out to investigate and compare the effectiveness of a direct and an indirect approach to data-driven learning (DDL) in facilitating Chinese learners' mastery of a challenging type of lexico-grammatical resource (i.e. hedges) in an undergraduate English-as-a-foreign-language (EFL) writing…

This study examined the effect of feedback, feed up (comments on goals and students' success in achieving goals) and feed forward (comments on the next step in learning during the semester) on writing motivation, writing self-efficacy, and writing anxiety. Two hundred and ten female intermediate language learners (age[subscript mean] = 17.2) were…

The present study deals with the effect of audio-visual material for second language (L2) pragmatic learning in the foreign language classroom. More specifically, it analyzes whether being exposed to captioned and non-captioned input in an experimental condition entailing no instruction on pragmatics might have any influence on the learners'…

The present study employed a mixed methods quasi-experimental design to investigate the effectiveness of applying motivational strategies and mental imagery (i.e. visionary techniques) to facilitate second language (L2) vocabulary learning. Four treatment sessions were integrated into a six-week language course offered to 150 intermediate students…

This study compared the effectiveness of deductive instruction and guided inductive instruction for developing semantic radical knowledge of Chinese characters. The evaluation was conducted through a quasi-experimental 3-week intervention involving 46 intermediate learners of Chinese as a foreign language (CFL). The results indicated that guided…

Prior research showed that interleaved practice (studying multiple skills at once) is more effective than blocked practice (studying only one skill at a time). This study aims to replicate the benefits of interleaved practice on the proceduralization of second language (L2) syntax and further examines the role of working memory (WM) in different…

This article examines the influence of different reading conditions (i.e. reading only and reading with first language marginal glosses), number of word encounters (one, three, and seven) while reading, and combinations of these two variables on new word retention. This study considered a total of six possible combinations. Six groups of Chinese…

This study examined the optimal learning schedule for second language vocabulary within an authentic classroom setting in Hong Kong. Following a pretest, treatment, delayed posttest design, fifty-two primary school students (Cantonese first language) studied 20 English adjectives over two learning episodes under spaced-short (1-day interval) or…
