To identify effective methods for boosting incidental vocabulary learning, this study examines the impacts of two tools--bimodal presentation (BP) and lexical elaboration (LE)--on vocabulary acquisition through repeated encounters with target words during meaning-focused reading. In a quiet and comfortable place conducive to full concentration on…

Recreational reading is in a decline for upper elementary aged readers, and along with this decline comes consequent declines in students' ability to make meaning from what they read and their acquisition of different language forms, including the acquisition of new vocabulary words. However, one reading format is increasing in popularity: graphic…

Retrieval practice of isolated words (e.g., with flashcards) enhances foreign vocabulary learning. However, vocabulary is often encountered in context. We investigated whether retrieval opportunities also enhance contextualized word learning. In two within-subjects experiments, participants encoded 24 foreign words and then read a story to further…

The authors examined the influence of context meaning consistency on incidental vocabulary acquisition during reading. "Context meaning consistency" refers to informational context that reflected the same meaning (i.e., consistent) or different meanings (i.e., inconsistent) across two self-paced reading sessions for a given item (both…

We explored whether knowledge building through read alouds of a conceptually coherent (CC) set of texts might support children's incidental acquisition of vocabulary in these texts and listening comprehension of related texts. Eleven classrooms of first (n = 83) and second grade students (n = 112) were randomly assigned to read alouds of either a…

This study investigated the effects of processing three types of texts, namely expository texts, narrative texts, and a combination of both known as twin texts, on incidental vocabulary acquisition and retention in L2 learners. College freshmen (N = 109), who were lower to upper intermediate learners of English, were assigned into a control group…

For elementary learners of Japanese, one of the main difficulties in reading is to distinguish words written in kana. This paper reports on a survey of elementary level learners with two different levels of proficiency to investigate the effectiveness of Japanese graded readers with parts of speech color-coded to distinguish nouns, verbs,…

This study measures the threshold level of depth of word knowledge in L2 incidental learning and reading comprehension. I administered the Word Associates Test (WAT; Read, 2004) to measure depth of word knowledge. Based on participants' scores on the WAT, they were divided into three proficiency groups: high proficiency (HP), intermediate…

This study examined whether the reading passages in the new series of English-language textbooks for high-school students in Vietnam fostered reading comprehension and incidental vocabulary acquisition through reading by looking at four factors: the number of unfamiliar words in the texts, the importance of these words for text comprehension, the…

Purpose: The purpose of this study was to investigate the effects of word-related factors (i.e. frequency, range, dispersion and cognateness) on first-language English (L1E) readers' (n = 20) and second-language English (L2E) readers' (n = 20) incidental acquisition of vocabulary through the reading of an authentic novel.…

Second language (L2) learners comprehend more when they are prepared for novel vocabulary that they encounter in a text. Input-based incremental (IBI) vocabulary instruction (Barcroft, 2012) provides L2 instructors and learners with a means of achieving this goal by (a) presenting optimal input to learners at the right time during a…

This study compared the effects of the reading-while-listening condition and the reading-only condition on English as a foreign language (EFL) learners' acquisition of the four dimensions of vocabulary knowledge: form recognition, grammar recognition, meaning recall, and collocation recognition. Accordingly, 24 words within four frequency groups…

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…

In the late 1980s Batia Laufer worked with teachers who believed that to understand a text it was enough to understand 80% of the text's word tokens. In response, Laufer set out to calculate the minimal text coverage, i.e., percentage of running words in a text the reader should understand to comprehend it reasonably well. In 1992, she explored…

In the field of second language acquisition (SLA), a large base of research has shown the great influence of L2 reading on L2 vocabulary acquisition. Nevertheless, researchers have also found that acquiring new vocabulary happens rather gradually and in small amounts. Without altering the incidental nature of vocabulary acquisition through…
