There is considerable evidence that incidental vocabulary acquisition through reading accounts for a large portion of the growth in word knowledge for both first (L1) and second (L2) language acquirers. In this paper, we evaluate the Markov Estimate of Semantic Association (MESA) technique for detecting small, incremental gains in vocabulary…

Enhancement Techniques are conducive to incidental vocabulary learning. This study investigated the effects of two types of enhancement techniques-multiple-choice glosses (MC) and L1 single-gloss (SG) on L2 incidental learning of new words and retention of them. A total of 89 university learners of English as a Foreign Language (EFL) were asked to…

The primary aim of this investigation was to determine what combination of target word variables (frequency, patternedness, length, cognateness, lexicalization) could best predict the difficulty of incidentally acquiring vocabulary through reading. A group of adult English First Language (EL1) (n = 20) and adult English as a Foreign Language (EFL)…

Previous studies have shown that intentional learning through explicit instruction is effective for the acquisition of collocations in a second language (L2) (e.g. Peters, 2014, 2015), but relatively little is known about the effectiveness of incidental approaches for the acquisition of L2 collocations. The present study examined the incidental…

This article reports on a classroom-based experiment that tested the effects of three vocabulary teaching constructs (involvement load, spacing, and intentionality) on the learning of English verb-noun collocations--for example, "shelve a plan." Laufer and Hulstijn's (2001) "involvement load" predicts that the higher the…

Based on a prior study by Chen and Truscott, the present study investigated the possible effects of repetition (repeated exposure) and L1 lexicalization on the incidental acquisition and retention of 10 English target words by 90 Persian-speaking EFL learners at an Iranian university. Seven aspects of vocabulary knowledge were measured, including…

This study investigates an instantiation of a 3D virtual world-based Japanese learning curriculum within the context of a Japanese as a foreign language (JFL) classroom. Through a mixed-method case study approach, participants' natural acquisition of Japanese in a 3D virtual environment was examined. In the present study, four sources of data from…

Recent years have witnessed a strong and increasing interest in the incidental learning of second language grammar. While much of this research has focused on the acquisition of second language word order or noun-determiner systems, relatively fewer studies have examined the learning of second language morphology. Results of studies that have…

This study investigates the relative effectiveness of different teaching approaches on the learning of formulaic sequences. Three comparisons were made in this study: the effects of explicit teaching of formulaic sequences versus teaching embedded in traditional coursebook instruction, the effects of the degree of salience of the sequences in the…

Dynamic assessment (DA), stemmed from both Vygotsky's (1978) learning theory and Feuerstein's (1979) theory of mediated learning experiences, is an alternative to static assessment. It focuses on both instruction and assessment aiming at promoting learning through mediation. DA has been widely researched in different linguistic areas, but there is…

Formulaic sequences (FS) are frequently used by native speakers and have been found to help non-native speakers sound more fluent as well. We hypothesized that explicitly teaching FS to classroom ESL learners would increase the use of such language, which could further result in increased second language (L2) fluency. We report on a 5-week study…

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…

Focus on form instruction is a kind of instruction that draws students, attention to linguistic elements as they arise incidentally in meaning based instruction. There are different types of focus on form instruction. The present study was designed to investigate the effect of incidental focus on form on grammatical accuracy among Iranian L2…

This study investigated the effects of differing densities of glossing on the uptake of target words and the comprehension of idea units from a reading text. The focus was whether different densities of glossing would create trade-off effects. Thirty-three Malaysian ESL learners were assigned to three different conditions: high-density glossing,…

The present study investigated the effect of form-focused and non-form-focused tasks on EFL learners' vocabulary learning through written input. The form-focused task aimed to draw students' attention to the word itself through word recognition activities. Non-form-focused tasks were divided into (a) the comprehension question task, which required…
