Indexen Voor Beurtwisselingsinitiatief in Tweede-Taal Verwerving

For optimal second language acquisition (SLA) classroom interactions have to allow normative speaking children to participate actively, because such initiative-rich participation enhances the children's development of linguistic and communicative competence. This article focuses on turn-taking initiatives. Turn-taking initiatives vary in their initiative strength. Restricting analysis exclusively to strong initiatives yields an incomplete picture of the contribution of a conversation to SLA. Less strong initiatives, too, must be taken into account. To analyze each utterance for its initiative value, a turn-taking taxonomy was developed, leading to turn-taking indices that represent the mean initiative value of all utterances by a speaker. Language data from kindergarten conversations show that only results on strong initiatives differ from results on turn-taking indices. It is argued that in order to assess the value of a conversation for SLA both kinds of measures, strong initiatives as well as indices, are necessary.
