The Impact of Dose and Dose Frequency on Word Learning by Kindergarten Children With Developmental Language Disorder During Interactive Book Reading

Method Thirty-four kindergarten children with DLD (aged 5;0–6;2 [years;months]) were taught 1 set of words using the Dose 6 and Dose Frequency 6 format from a prior study (Storkel, Voelmle, et al., 2017) and taught a different set of words using an alternative format, either Dose 4 × Dose Frequency 9 or Dose 9 × Dose Frequency 4, determined through random assignment. Word learning was tracked for each treatment via a definition task prior to, during, and after treatment. Results Results showed that children with DLD learned a significant number of words during treatment regardless of the dose and dose frequency format but that significant forgetting of newly learned words occurred in all formats once treatment was withdrawn. Individual differences in word learning were related to Clinical Evaluation of Language Fundamentals Core Language and Understanding Spoken Paragraphs scores. Conclusion When administered at an adequate intensity, variation in the dose and dose frequency of interactive book reading does not appear to influence word learning by children with DLD. Although interactive book reading continues to show promise as an effective word learning intervention for children with DLD, further development is needed to enhance the effectiveness of this treatment approach

Exploratory Study of a Team-Based Model of Transition Professional Development

This article shares the results from a quasi-experimental mixed-methods study of a promising transition-focused professional development approach. The 12-week team-based intervention resulted in positive outcomes among intervention group participants’ knowledge and capacities. The intervention group exhibited statistically significant changes in knowledge of transition assessment practices as well as in using various types of age-appropriate transition assessments and implementing effective practices associated with a comprehensive transition assessment process. At the program level, findings indicated team-level indicators showed statistically significant improvements. The study demonstrated teams who received the intervention were more likely to attain a program-level goal, which was substantially greater than the comparison teams. Implications for future research and practice are shared
