In this quasi-experimental study, 165 learners of English for academic purposes at a university in China were randomly assigned to five experimental groups and a control group. Each experimental group encountered 19 target collocations in the same academic lecture in one of the following input modes: (a) reading, (b) listening, (c) reading while…

Knowledge of English affixes plays a significant role in increasing knowledge of words. However, few attempts have been made to create a valid and reliable measure of affix knowledge. The Word Part Levels Test (WPLT) was developed to measure three aspects of affix knowledge: form (recognition of written affix forms), meaning (knowledge of affix…

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…

This study investigated Vietnamese EFL learners' knowledge of verb-noun and adjective-noun collocations at the first three 1,000 word frequency levels, and the extent to which five factors (node word frequency, collocation frequency, mutual information score, congruency, and part of speech) predicted receptive knowledge of collocation. Knowledge…

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.…

Japanese university students learning English as a foreign language (EFL) encountered 10 target words in 3 sets of 10 short contexts that were rated on the amount of information available to infer the target words' meanings. One group of learners met the target words in contexts rated more highly than the contexts read by the other group. A…

Previous research investigating the effects of contextualized and decontextualized tasks on vocabulary learning has focused on whether or not learners were able to gain knowledge of meaning and form. To date, research has generated little evidence indicating that context facilitates vocabulary learning. Decontextualized tasks tend to be equally or…
