<div dir="ltr">Hi,<div><br></div><div>I am exploring teacher-child interactions in which a teacher is having small group conversations with about 6 children in each group. Each group is observed at five time points. The observations range from about 7-19 minutes.</div><div>I am measuring the children's expressive language in total number of words/min, MLU, and VOCD. </div><div><br></div><div>I am wondering about the VOCD measure. Some of the children do not produce 50 tokens, and therefore VOCD cannot be calculated for these children.</div><div>Is there a way of measuring lexical diversity in another way?</div><div>I know that TTR is problematic due to differences in speech sample length, which is indeed the case in my study.</div><div>Can number of different words in a rate per minute be an alternative?</div><div><br></div><div>I am thankful for ideas and support.</div><div><br></div><div>Best Regards,</div><div>Karin Edlund, Ph.D student, Sweden</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div></div>
