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…

Four experiments were conducted to examine the role of orthotactic probability, i.e. the sequential letter probability, in the early stages of vocabulary acquisition by adult native speakers and advanced learners of German. The results show different effects for orthographic probability in incidental and intentional vocabulary acquisition: Whereas…

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…

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…

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…

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 compares the impact of second language (L2) reading and listening on the incidental acquisition and retention of five dimensions of vocabulary knowledge--spoken form, written form, part of speech, syntagmatic association, and form-meaning connection--at the level of recognition (form-meaning connection was measured also at the level of…

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…

This study investigates the role of morphological awareness in the incidental learning of Mandarin Chinese characters among Chinese as second language (CSL) learners. Participants of the study were 20 college-level international students, uniformly Thai in language background, enrolled to study CSL at Southwest University, Chongqing, China. The…

In this paper the incidental language acquisition of 11-year-old Flemish children (n = 30) who have not received any formal English instruction is investigated. The study looks into children's English proficiency and the learner characteristics that can be associated with it. In order to measure the children's English proficiency, a receptive…

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…
