This article reviews the empirical research on incidental vocabulary acquisition in English reading in the latest twenty years from three aspects: its comparison with intentional vocabulary acquisition, its affecting factors and previous studies of its problems. Teaching implications have also been provided.

Vocabulary development is a crucial aspect of literacy. It is our duty as teachers to enrich the language of our students to better prepare them for a successful lifetime of communication. This paper offers several methods to enhance levels of speech in the classroom. Some of the techniques included are the use of repetitive reading, reading…

Developing young children's vocabulary is essential for later reading success; thus, early childhood classrooms require a comprehensive vocabulary approach that teaches academic vocabulary. Yet even providing young children with child-friendly definitions of sophisticated words can be a challenge. First, the authors outline the components of a…

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…

Providing glosses that explain the meanings of unknown words is a common method of promoting learners' learning of new words. Numerous studies have shown that compared with no-gloss condition, glosses benefit the learning of the meaning of new words. This study combines both online (i.e., eye-tracking) and offline (i.e., immediate vocabulary…

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…

Vocabulary is an essential factor in English language learning. The competency in vocabulary acquisition enables learners to develop their language skills, especially, reading skill. Presently, with the advent of technology, teaching media with visual aid is used worldwide for media-assisted language learning. The study aimed to develop, implement…

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…

Research has shown a strong positive relationship between vocabulary knowledge and reading comprehension (Elleman, Lindo, Morphy, & Compton, 2009; Crosson & Lesaux, 2013; Lubliner & Smetana, 2005). Vocabulary acquisition is possible for all learners through explicit vocabulary instruction and incidental word learning (Cunningham,…

Learning style matching is a neglected factor that may affect the complex process of second language (L2) incidental vocabulary acquisition through reading. The purpose of the current study is to investigate whether there is any difference in L2 incidental vocabulary acquisition and retention through reading when learners' perceptual learning…

Hyperglossing -textual and/or pictorial representations of lexical items is found to be aiding the development of decoding, and narrow reading is a useful strategy for L2 reading pedagogy. Although the research on glossing provides mixed findings regarding the benefits, it is also acknowledged that glossing improves especially incidental…

Provision of multiple-choice (MC) glosses, which combines the advantages of glosses and inferring, has recently gained its share of supporters as a potential technique for enhancing L2 texts and increasing word gain for L2 learners. Upon taking an actual TOEFL, the participants underwent a vocabulary pretest to ensure that the target words were…

This study investigated whether enhanced extensive reading contributed to significant gains on the incidental acquisition of English prepositions. English as a Foreign Language (EFL) secondary school students in Korea ("N" = 12) received enhanced extensive reading instruction for one semester in an after-school program. Pre-and…

Reciprocal peer tutoring can be an effective supplement to teacher-led instruction, but students need to have the tutoring skills necessary to teach their peers successfully. Previous studies have addressed the challenge of providing essential information to a naive tutor, allowing for correct modeling and feedback. The present study compared…
