English-medium instruction (EMI) is gaining popularity among EFL higher education institutions. However, not all EMI programs provide the same English immersion as those in the Anglosphere. The researcher targeted English medium university textbooks as a research focus, since they are first and foremost learning material of specialist knowledge…

This longitudinal study investigates the effect of mode of reading on the incidental learning of collocations and factors that affect learning. One hundred Vietnamese pre-intermediate learners of English as a foreign language (EFL) were assigned to either an experimental group or a control group (no treatment). In 9 weeks, the experimental group…

English-medium instruction (EMI) has become a nationwide trend in Taiwan's higher education institutions. Behind this rapid growth is the widespread belief that EMI provides English immersion, which facilitates incidental learning of the target language. However, not all EMI programs in EFL contexts provide the same immersion as those in the…

This study analyzed eTandem video-conferencing exchanges between five pairs of university students of English as a foreign language (EFL) and Spanish as a foreign language (SFL). The exchanges, which involved discussion of seven tasks, took place on a weekly basis. Drawing on an interactionist perspective (Ellis et al., 2001a; Loewen, 2005), the…

Previous studies on lexical focus on form (FonF) have mostly centred on FonF in reading with a few pre-selected lexical items. This study investigated the contribution of oral incidental FonF to developing learners' lexical knowledge in a free discussion EFL class. Incidental FonF was provided to 15 upper-intermediate learners who participated in…

An English reading class of 10th graders (N = 50) was asked to self-construct English word cards for unknown vocabulary incidentally encountered when completing textbook readings. The students were assigned this task to determine what linguistic and nonlinguistic elements they would self-select to include on the cards and whether the appearance of…

Academic lectures are potential sources of vocabulary learning for second language learners studying at universities where English is the medium of instruction, as well as those in English for Academic Purposes (EAP) programs. Topic-related vocabulary is likely to occur frequently in academic texts, and academic speech consists of a reasonable…

Ensuring second language (L2) learners have an adequate breadth and depth of L2 vocabulary knowledge is a key pedagogical objective in L2 learning contexts. For this reason, establishing guiding principles that successfully enhance the efficacy of L2 vocabulary knowledge development is of strong importance. The current study investigated the value…

This article explores the pedagogical practices used by high school teachers in integrating disciplinary and language knowledge in a multilingual context where English is the medium of instruction. Specifically, we explored the way high school teachers implement the English Across the Curriculum (EAC) strategy in their content subjects. EAC is an…

We investigated how positive, negative, and neutral mood states influence aspects of second language acquisition, either directly or in interaction with certain personality characteristics (openness, intuition, emotional intelligence, foreign language anxiety, and impulsivity). After completing individual differences questionnaires, 120…

This study investigates the potential benefits for incidental vocabulary acquisition of implementing a particular sequence of input--output--input activities. More specifically, learners of English as a foreign language (EFL; n = 32) were asked to watch a TED Talk video, orally sum up its content in English, and then watch the video once more. A…

Research on corrective feedback (CF) and language teachers' beliefs and practices on the provision of CF has been mainly limited to learners' non-target-like use of grammar, vocabulary, pronunciation, and spelling (non-formulaic forms). Consequently, learners' non-target-like use of formulaic sequences, that is, collocations, idioms, lexical…

This paper computes estimates of the potential for Extensive Reading (ER) and Extensive Viewing (EV) to support the academic and discipline-specific vocabulary needs of students. While research into ER/EV for general vocabulary is well-established, only recently has academic vocabulary begun to be researched. Given curriculum time constraints,…

Language researchers and teachers have long been interested in the timing of learning, and the distributed practice effect, whereby greater inter-session intervals result in longer retention, is well-known (Kim & Webb, 2022). Many L2 studies have focused on the intentional learning of lexis (Edmonds, Gerbier, Palasis, & Whyte, 2021),…

This study examines the effect of textual enhancement on learners' attention to and learning of multiword units from captioned audiovisual input. We adopted a within-participants design in which 28 learners of English as a foreign language (EFL) watched a captioned video containing enhanced (underlined) and unenhanced multiword units. Using…
