Combining explicit and sensitive indices for measuring L2 vocabulary learning through contextualized input and word-focused instruction
Journal Contribution - Journal Article
This study combines explicit (pen-and-paper) and sensitive (time-pressured) measures to gauge the impact of three instructional interventions (contextualized input with meaning-focused activities, contextualized input with word-focused activities, and decontextualized input with word-focused exercises) on the learning of 20 L2 French target verbs. Participants (N = 313, L1 = Dutch) completed a combination of explicit (form recognition, meaning recall, grammatical preference) and time-pressured sensitive tests (lexical decision, semantic relatedness, grammaticality judgment) as immediate and delayed posttests. Explicit posttests show the beneficial effects of word-focused instruction, and underline the efficiency of context for meaning-related knowledge. Sensitive posttests generally confirm the explicit results, but reveal differences between both word-focused conditions related to lexical processing and strength of knowledge. This study suggests that combining explicit and sensitive measures can provide a more complete picture about the effects of L2 vocabulary instruction and shows that contextualized and decontextualized word-focused instruction benefit vocabulary learning in a complementary way.
