Effects of sentence writing in second language lexical acquisition

This study compared the effects of writing new words in sentences with word-picture repetition learning alone. Second language (L2) Spanish learners attempted to learn 24 new Spanish words in one of two conditions while viewing word-picture pairs. In Experiment 1, in the no sentence writing condition, the participants viewed 4 repetitions of each word for 6 seconds each. In the sentence writing condition, they viewed 1 repetition of each word for 48 seconds and were asked to write the word in a Spanish sentence. In Experiment 2, the participants were shown one repetition of each word for 24 seconds in both the sentence writing and no sentence writing conditions. Immediate and delayed posttests on productive vocabulary knowledge were administered in both experiments. Scores were submitted to analyses of variance. Condition and time were independent variables. Target word production was scored based on syllables and whole words produced. Results of both experiments indicated strong negative effects for the sentence writing conditions, suggesting that sentence writing can inhibit word form learning during the initial stages of L2 lexical acquisition.
