Learning vocabulary is a central but yet complex aspect of learning a language. Hence, researchers stress the importance of facilitating vocabulary development via a structured approach to target words and recycling. While teaching materials have the potential to provide this structure to all students in a classroom, few studies have investigated…

One of the major challenges for any L2 teacher is to integrate vocabulary components into a course. Determining what words to select in order to satisfy the goals of the course and what instructional methodology best suits the purpose of vocabulary learning are not easy tasks. Even more difficult is dealing with the formulaic terminology of a…

Vocabulary is often considered as a key predictor of second language ability, and how teachers and learners' beliefs and conceptualizations about vocabulary affect their teaching and learning has recently gained unprecedented momentum in the field of second language education. However, despite their importance, there is a paucity of research that…

This study investigates the impact of task-induced involvement and time on task on incidental second language (L2) vocabulary acquisition. Utilizing a 3 (task-induced involvement) × 2 (time on task) × 2 (post-test time) research design, three task-induced involvement conditions were employed based on the Involvement Load Hypothesis (ILH): reading…

In Thailand, the traditional teaching approach used for English language classes has been to explicitly teach English grammar, but in recent years the strategy has begun to shift towards the implicit teaching of language via communicative techniques. Within academic circles, there has been minimal agreement on the suitability of approaches used.…

With the aim of investigating effective approaches to extensive reading in Thailand, this study examined the vocabulary uptake and retention rate from reading 350 headwords graded reader. To determine the effects of reading a graded reader on students' vocabulary knowledge and retention, 20 words within four bands of different frequencies of…

This study investigated the lexical demands of English-as-an-additional-language (EAL) and general-audience podcasts and their potential for incidental vocabulary learning. Two corpora (i.e., one EAL and one general-audience) comprising 1,188,512 tokens were analyzed to determine the necessary vocabulary knowledge to reach 90% and 95% coverage.…

Recently vocabulary studies have mainly focused on two forms of vocabulary acquisition: incidental and intentional vocabulary acquisition. For incidental vocabulary acquisition, Task-induced Involvement Load Hypothesis (TILH) was put forward by Hulstijn and Laufer (2001) to investigate the vocabulary tasks by comparing their levels of involvement…

This study explored the effects of listening-based lexical focus-on-form (lexical FonF) on the acquisition and retention of morphologically complex words. One hundred eighty-two adult English learners with two levels of English proficiency (higher and lower proficiency) from a public university in mainland China were assigned to three different…

Research shows that meaning-focused reading offers opportunities for incidental grammar acquisition. However, the number of such studies remains limited and none have examined the role of both in-text encounters with grammar structures and reading comprehension in this learning. The present study filled these gaps. Employing a between-group,…

Working memory (WM) may be an essential component of incidental vocabulary learning and retention from captioned videos. However, how WM affects young learners' incidental vocabulary learning under different types of captions remains unclear. The present study employs a between-subject research design. The main purpose is to examine how two types…

The aim of this study is to analyze the effect of different schedules of repeated reading practice on intentional vocabulary learning, and constitutes a partial replication and extension of the authors' previous study on incidental vocabulary learning. Two groups of Taiwanese EFL learners (n = 72) engaged in five repeated reading sessions; one…

Mobile-based extramural English (EE) activities, including watching movies, playing digital games, and listening to music outside the classroom, have played an important role in increasing learners' interest in English as a foreign language (EFL). This mixed-method design study aimed to investigate the role of EE activities in the vocabulary…

The present meta-analysis aimed to improve on Involvement Load Hypothesis (ILH) by incorporating it into a broader framework that predicts incidental vocabulary learning. Studies testing the ILH were systematically collected and 42 studies meeting our inclusion criteria were analyzed. The model-selection approach was used to determine the optimal…

The increasing number of students with German as a second language (GL2) poses a great challenge for schools. Previous studies showed that especially young learners with a migration background are lagging behind in the acquisition of second language (L2) literacy. Experiencing problem behaviors (PB) in addition, might pose even greater challenges.…
