Purpose: Variability in the input plays an important role in language learning. The current study examined the role of object variability for new word learning by preschoolers with specific language impairment (SLI). Method: Eighteen 4- and 5-year-old children with SLI were taught 8 new words in 3 short activities over the course of 3 sessions.…

This study investigated the effect of input-based tasks on the acquisition of vocabulary and grammar by beginner-level learners of L2 French and reported the introduction of task-based teaching as an innovation in a state secondary school. The experimental group (n = 19) completed a series of focused input-based language tasks, taught by their…

Both the input directed to the child, and the child's ability to process that input, are likely to impact the child's language acquisition. We explore how these factors inter-relate by tracking the relationships among: (a) lexical properties of maternal child-directed speech to prelinguistic (7-month-old) infants (N = 121); (b) these infants'…

The present study was designed to investigate empirically the effect of Vocabulary Self-Selection strategy and Input Enhancement strategy on the vocabulary knowledge of Iranian EFL Learners. After taking a diagnostic pretest, both experimental groups enrolled in two classes. Learners who practiced Vocabulary Self-Selection were allowed to…

Input enhancement's role to promote learners' awareness in L2 contexts has caused a tremendous amount of research. Conspicuously, by regarding all aspects of input enhancement, the study aimed to find out how differently many kinds of input enhancement factors such as bolding, underlining, and capitalizing impact on L2 learners' vocabulary…

Vocabulary as a significant component of language learning has been widely researched. As well, it is well documented that vocabulary could be learned through listening and reading. In addition, measuring productive vocabulary has been a chief concern among scholars. However, few studies have focused on meaning-focused listening input and its…

Adult second language (L2) learners have often been found to produce discourse that manifests limited and non-native-like use of multiword expressions. One explanation for this is that adult L2 learners are relatively unsuccessful (in the absence of pedagogic intervention) at transferring multiword expressions from input texts to their own output…

One crucial aspect of Content and Language Integrated Learning (CLIL)-based foreign language learning in instructional settings is vocabulary growth. As a consequence, research should be interested in how CLIL fosters vocabulary learning. Noticing an apparent shortage of data-driven quantitative research on vocabulary growth in this field of CLIL…

We trained forty German-speaking children aged 1;8-2;0 in their comprehension of UNTER [UNDER]. The target word was presented within semantically organized input in the form of a "narrative" to the experimental group and within "unconnected speech" to the control group. We tested children's learning by asking them to…

In the present study, the comparative effects of comprehensible input, output and corrective feedback on the receptive acquisition of L2 vocabulary items were investigated. Two groups of beginning EFL learners participated in the study. The control group received comprehensible input only, while the experimental group received input and was…

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…

The study aimed to investigate whether or not negotiation of meaning is effective in L2 vocabulary acquisition of Chinese learners of English in the classroom setting. In the study there were two experimental groups (pre-modified input and negotiation of meaning) and two control groups (pre-modified input). The four groups were required to do a…

The present study was an attempt to investigate the effects of premodified input, interactionally modified input and modified output on 80 EFL learners' comprehension of new words. The subjects were randomly assigned into four groups of pre modified input, interactionally modified input, modified output and unmodified (control) groups. Each group…

Current literature points to the importance and benefits of extensive reading. Extensive reading provides contextualized clues for better reading comprehension (Krashen, 1982), and substantial linguistic input (Bell, 1998) needed for language development. Several studies have found a correlation between extensive reading and specific linguistic…
