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 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 investigates the effects of cognacy on vocabulary learning. The research expands on earlier designs by measuring learning of English-Japanese cognates with both decontextualized and contextualized tests, scoring responses at two levels of sensitivity, and examining learning in a more ecologically valid setting. The results indicated…

This study investigated (1) the extent of vocabulary learning through reading and listening to 10 graded readers, and (2) the relationship between vocabulary gain and the frequency and distribution of occurrence of 100 target words in the graded readers. The experimental design expanded on earlier studies that have typically examined incidental…

Many contemporary textbooks for English as a foreign language (EFL) and books for vocabulary study contain exercises with a focus on collocations, with verb-noun collocations (e.g. "make a mistake") being particularly popular as targets for collocation learning. Common exercise formats used in textbooks and other pedagogic materials…

This study investigated the potential of pre-learning frequently occurring low-frequency vocabulary as a means to increase comprehension of television and incidental vocabulary learning through watching television. Eight television programmes, each representing different television genres, were analysed using the RANGE program to determine the 10…

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…
