Purpose Augmentative and alternative communication (AAC) is an intervention approach that can promote communication and language in children with multiple disabilities who are beginning communicators. While a wide range of AAC technologies are available, little is known about the comparative effects of specific technology options. Given that engagement can be low for beginning communicators with multiple disabilities, the current study provides initial information about the comparative effects of 2 AAC technology options—high-tech visual scene displays (VSDs) and low-tech isolated picture symbols—on engagement. Method Three elementary-age beginning communicators with multiple disabilities participated. The study used a single-subject, alternating treatment design with each technology serving as a condition. Participants interacted with their school speech-language pathologists using each of the 2 technologies across 5 sessions in a block randomized order. Results According to visual analysis and nonoverlap of all pairs calculations, all 3 participants demonstrated more engagement with the high-tech VSDs than the low-tech isolated picture symbols as measured by their seconds of gaze toward each technology option. Despite the difference in engagement observed, there was no clear difference across the 2 conditions in engagement toward the communication partner or use of the AAC. Conclusions Clinicians can consider measuring engagement when evaluating AAC technology options for children with multiple disabilities and should consider evaluating high-tech VSDs as 1 technology option for them. Future research must explore the extent to which differences in engagement to particular AAC technologies result in differences in communication and language learning over time as might be expected.

Purpose This pilot study explored the effectiveness of an early storybook reading (ESR) intervention for parents with babies with hearing loss (HL) for improving (a) parents' book selection skills, (b) parent–child eye contact, and (c) parent–child turn-taking. Advancing research into ESR, this study examined whether the benefits from an ESR intervention reported for babies without HL were also observed in babies with HL. Method Four mother–baby dyads participated in a multiple baseline single-case experimental design across behaviors. Treatment effects for parents' book selection skills, parent–child eye contact, and parent–child turn-taking were examined using visual analysis and Tau-U analysis. Results Statistically significant increases, with large to very large effect sizes, were observed for all 4 participants for parent–child eye contact and parent–child turn-taking. Limited improvements with ceiling effects were observed for parents' book selection skills. Conclusion The findings provide preliminary evidence for the effectiveness of an ESR intervention for babies with HL for promoting parent–child interactions through eye contact and turn-taking.

Zusammenfassung. Am Beispiel des Rechnens in der Grundschule wird eine Weiterentwicklung des amerikanischen „Curriculum – based measurement” demonstriert. Ein ganzes Jahr lang erhalten 190 Kinder aus sieben Grundschulklassen und drei Sonderschulklassen alle zwei Wochen einen Rechentest. Bei den Tests handelt es sich um Zufallsstichproben aus Grundgesamtheiten von Aufgaben, die dem Lehrziel für jedes der Schuljahre entsprechend definiert sind. Für jedes Kind und jeden Termin wird eine eigene neue Zufallsstichprobe generiert, so dass kein Test zweimal gegeben wird, ein jeder aber die geforderte Fertigkeit kontentvalide erfasst. Solche Tests lassen sich als kriteriumsorientierte Binomialtests darstellen. Im vorliegenden Beitrag wird (1) das ursprüngliche Konzept und seine Weiterentwicklung kurz vorgestellt, (2) empirisch getestet, ob das neue Verfahren geeignet ist, von Klassenlehrern vertretbar eingesetzt zu werden, und (3) werden Ausblicke auf dringend erwünschte weiterführende Forschungen geboten. Die vorgelegten Daten erlauben, das Spektrum von Verläufen auf Klassen- wie Individualebene zu dokumentieren, aber auch, die Probleme und vielversprechenden Möglichkeiten des Ansatzes kritisch offen zu legen.
