Open access academic lectures are potential sources for incidental vocabulary learning. These lectures are available in various formats (transcripts, audios, videos, and video with captions), but no studies have compared the learning of vocabulary in these lectures through different input modes. This study adopted a pretest-posttest design to…

There has been little research investigating how mode of input affects incidental vocabulary learning, and no study examining how it affects the learning of multiword items. The aim of this study was to investigate incidental learning of L2 collocations in three different modes: reading, listening, and reading while listening. One hundred…

Academic lectures are potential sources of vocabulary learning for second language learners studying at universities where English is the medium of instruction, as well as those in English for Academic Purposes (EAP) programs. Topic-related vocabulary is likely to occur frequently in academic texts, and academic speech consists of a reasonable…

This study used a pretest-posttest-delayed posttest design at one-week intervals to determine the extent to which written, audio, and audiovisual L2 input contributed to incidental vocabulary learning. Seventy-six university students learning EFL in China were randomly assigned to four groups. Each group was presented with the input from the same…

Previous research has furnished evidence that alliterative expressions (e.g. "a slippery slope") are comparatively memorable for second language learners, at least when these expressions are attended to as decontextualized items (Lindstromberg and Boers, 2008a; Boers et al., 2012). The present study investigates whether alliteration…

The researchers completed a corpus-driven analysis of 688 texts written for children, language learners, and older readers to determine the vocabulary size necessary for comprehension and the potential to incidentally learn vocabulary through reading each text type. The comparison between texts written for different audiences may indicate their…

This study investigated the effects of repetition on the learning of collocation. Taiwanese university students learning English as a foreign language simultaneously read and listened to one of four versions of a modified graded reader that included different numbers of encounters (1, 5, 10, and 15 encounters) with a set of 18 target collocations.…

Previous research investigating the effects of unassisted and assisted repeated reading has primarily focused on how each approach may contribute to improvement in reading comprehension and fluency. Incidental learning of the form and meaning of unknown or partially known words encountered through assisted and unassisted repeated reading has yet…

This article examines the effects of synonymy (i.e., learning words with and without high-frequency synonyms that were known to the learners) on word knowledge in a study of 84 Japanese students learning English. It employed 10 tests measuring 5 aspects of word knowledge (orthography, paradigmatic association, syntagmatic association, meaning and…
