The authors Lila Carson, Susan Miller and Karen Noll from Valdosta State University in Valdosta, Georgia present some very useful information on how to use vowel drills to facilitate /r/ production.
We were very pleased that they used The Entire World of R Advanced Screening as their pre- and post-test assessment. The Entire World of R Advanced Screening looks at 32 different types of /r/, including vocalic /r/ and /r/ blends in multiple contexts and complexities. The assessment provides detailed information to determine present level of performance for an initial baseline. This information from the screening is invaluable in selecting intervention targets and monitoring the response to treatment. Data from the screening as the article displays is sufficiently rich enough to collect data for a research study. We feel this is the most comprehensive evaluation tool for /r/ and the authors apparently agreed.
What has been your experience with The Entire World of R Advanced Screening? How has it help you in your evaluation and treatment?
