This paper contributes to a research program within extensive reading (ER) and "Reading in a Foreign Language" using corpora to simulate ER input to develop vocabulary through incidental learning to 9,000 words. This helps researchers/teachers evaluate ER. If corpora indicate no 'pathway' from smaller to larger vocabulary sizes through…

The incidental or implicit learning of vocabulary has long been a topic of interest in various disciplines. In studies on foreign language acquisition, reading is often the activity that researchers use to generate their findings. "Reading in a Foreign Language" has maintained its position at the forefront of this research, consistently…

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…

Aka (2019) conducted an year-long large-scale study demonstrating that Japanese high school students who undertook extensive reading performed better than a control group who undertook grammatical instruction. Those showing the greatest gains were those of lower and intermediate proficiency. The students' achievement was measured in terms of…

This study looks at how much input is needed to gain enough repetition of the 1st 9,000 words of English for learning to occur. It uses corpora of various sizes and composition to see how many tokens of input would be needed to gain at least twelve repetitions and to meet most of the words at eight of the nine 1000 word family levels. Corpus sizes…

Extensive reading is one of a range of activities that can be used in a language learning course. Ideally, the choice of activities to go into a course should be guided by principles which are well supported by research. Similarly, the way each of those activities is used should be guided by well-justified principles. In this article, we look at…

This study investigates the vocabulary learning opportunities in an ELT course book designed for upper-intermediate learners. All the words appearing in the 12 chapters of the text were analyzed. The results suggest that the text would provide opportunities to deepen knowledge of the second 1,000 most frequent words in English, and would provide a…

Opportunities for incidental vocabulary acquisition were explored in a 121,000-word corpus of teacher talk addressed to advanced adult learners of English as a second language (ESL) in a communicatively-oriented conversation class. In contrast to previous studies that relied on short excerpts, the corpus contained all of the teacher speech the…

This longitudinal case study tracks an adult second-language (L2) learner's quality and quantity of encounters with 20 vocabulary items in an English for Academic Purposes course over 3 months. The learner completed pretest and posttest vocabulary knowledge interviews, submitted course materials and notes for analysis, and was observed during…

This study examined the rate at which English vocabulary was acquired from the 3 input modes of reading, reading-while-listening, and listening to stories. It selected 3 sets of 28 words within 4 frequency bands and administered 2 test types immediately after the reading and listening treatments, 1 week later and 3 months later. The results showed…

Fourteen collections of children's reading materials were used to investigate the claim that collections of authentic texts with a common theme, or written by one author, afford readers with more repeated exposures to new words than unrelated materials. The collections, distinguished by relative thematic tightness, authorship (1 vs. 4 authors),…
