This study examined the effects of a collaborative writing sequence on vocabulary learning among French elementary school students. Two sixth grade groups participated in this quasi-experimental study. Each group completed two preparation sessions and three writing sessions preceded by the explicit teaching of five target words. Participants in the experimental group wrote in teams of four while those in the control group wrote individually. Participants’ target word knowledge was measured prior to and upon completion of the intervention. Results of an ANOVA analysis of variance revealed no significant difference between the two groups on target word knowledge following intervention. Our findings suggest that collaborative writing and individual writing both lead to similar acquisition of vocabulary. Strategies for promoting vocabulary acquisition in the classroom are discussed.
