[Linganth] FW: Word Gap intervention evaluation studies?

[Woolard, Kathryn]

Many thanks to those who’ve responded with suggestions. Here is one from Michele Koven, who’s having trouble posting to the list.

So far I haven’t found evaluations/critiques of evaluations of the actual interventions such as Providence Talks or the 30 Million Word Initiative, which particularly interest me. Cartmill 2016 mentions that it was too early for those at the time of writing.

Best to all,
Kit

Hi,

Here is a popular press link that summarizes Doug Sperry’s findings that challenge the word gap.

Does anyone have references for, and/or a critical summary of, follow-up evaluation studies of home language socialization interventions based on the “Word Gap” model, such as “Providence Talks” or other LENA-based interventions?
Brief googling has led me only to short (glowing) news reports 2017-18 and an unpublished ms. of a Brown University study of Providence Talks, which falls far short in research standards in my view. For evaluation of change in child language skills, it uses only a self-administered parent evaluation form devised and provided by LENA itself to its participants.

Thanks for any leads.
