    The ModelER intervention package is built on theory supporting the importance of language input (Gallway & Richards, 1994; Hart & Risley, 1995, Tomasello, 2003) and effective instructional components as highlighted in AAC modeling research (Sennott et al., 2014).

    ModelER

    The Improving Partner AAC Training (ImpAACt) series of studies (e.g. Binger et al., 2008) effectively used variants of a specific strategy instructional package (Read, Ask, and Answer [RAA] and related variants) to teach partners to better engage in shared storybook reading with beginning communicators who use AAC. These studies demonstrated positive results in the form of increased communication turns (Kent-Walsh et al, 2010; Rosa-Lugo & Kent-Walsh, 2008), increased multi-symbol communication turns (Binger et al., 2008, Binger, Kent-Walsh, Ewing, & Taylor, 2010), and increased use of morphological forms (Binger, Maguire-Marshall, & Kent-Walsh, 2011). ModelER has been designed to build on the findings of the ImpAACt research, but to optimize for generalization beyond the context of shared storybook reading, because of the importance of promoting interventions that can be used across multiple contexts (e.g. play, academics, snack/ meal times) for children learning to use AAC.

    The major components of ModelER are (a) model - modeling AAC use (Sennott et al., 2014); (b) encourage - encouraging communication through time delay/ expectant delay (e.g. Halle, Baer, & Spradlin, 1981); and (c) respond - responding to child communication attempts through AAC recasting (Camarata & Nelson, 2006; Nelson et al., 1996; Harwood, Warren, & Yoder, 2003). AAC modeling is the foundation of the intervention and is designed to provide a model of language use (pragmatics), content (semantics), and form (syntax and morphology) for the individual with CCN learning to use AAC. Encouragement to communicate, in the form of a time delay, is designed to provide opportunities for the child to initiate a communication turn, showing them that the adult communication partner is waiting and interested. As a support to the child’s communication attempts, the respond component focuses on recasting the child’s utterance by repeating their utterance, and expanding it in a meaningful way. The respond component is designed as an adaptation of the recasting intervention described in Nelson et al. (1996), which described that the recast maintains the basic meaning of what they child says, focuses on expanding the length of utterance, and keeps the conversation turns flowing. The hope is that the child can better attend to the more advanced structures being modeled because the utterance is based on what they just previously communicated. Put together, the sequence of modeling, encouraging by waiting for the child to take a turn, and then responding through AAC recasting is designed to create individualized, language-rich multi-turn communication sequences.

    Read and Talk

    The Read and Talk component of the package refers to reading a book and talking about it through making comments or asking questions. The Read and Talk components create a learning environment that would be typical of an early childhood shared reading context. Variants of shared storybook reading, such as dialogic reading, that includes engaging in conversation with the child, has extensive empirical support in general education (Dale et al., 1996; Whitehurst et al., 1988), special education (Ezell & Justice, 2005), and AAC specific literatures (Bedroisian, 1999; Sennott et al., 2014; Stephenson, 2009). Dialogic reading interventions (e.g. Dale et al., 1996) are comprised of reading with children and asking targeted questions, which matches the approach the RAA strategy ImpAACt studies took (e.g. Kent-Walsh et al., 2010), which primarily focused on reading and question asking. By including commenting in addition to question asking, the approach taken in the Read and Talk components of the intervention expands on the scope of adapting dialogic reading for children using AAC. The decision to include both commenting and question asking was made because question asking has the potential to place the child into a passive or question prompt–dependent role, which could be detrimental to individuals who require AAC (Light & Kelford Smith, 1993). Instead, this approach is designed to teach the communication partners to model multiple pragmatic functions, comments, and questions, with the objective of promoting the children taking increasingly independent turns such as making comments or asking questions themselves.

    Table 2.4.1: MODELER Implementation checklist
    Strategy Step Description
    Model EA models one or more AAC symbols during a communication turn using the iPad based AAC system.
    Encourage EA provides a time delay, or wait time, until child takes a communication turn or five seconds.
    Respond EA responds to a child communication turn with an AAC recast by repeating some portion of the child’s utterance and attempts to expand the utterance and models one or more AAC symbols during a communication turn using the iPad-based AAC system
    Read EA reads a page or page spread in the book and uses ModelER
    Talk EA makes a comment or asks a question using ModelER

    Conclusion

    For children who are minimally verbal and use AAC it is important to develop an expressive language system and to have an appropriate language learning environment. The iPad combined with a communication app has become a very popular AAC system, creating more opportunities for these children to have access to expressive language. A number of useful resources have been introduced in this chapter from various web sources. Specifically, the naturalistic communication intervention MODELER has been introduced.

    In considering the language learning environment of children, we know about the importance of language input described across general language acquisition (Gallway & Richards, 1994; Gerken, 2008; Hart & Risley, 1995, Tomasello, 2003), sign language (Bavelier et al., 2003; Newport & Supalla, 2000), and AAC (Goosens, Crain, & Elder, 1992; Romski & Sevcik, 1996; Sennott et al., 2013; Smith & Grove, 2003). AAC researchers have developed interventions that target providing models of AAC use. Sennott and colleagues have developed a package intervention called MODELER (Model, Encourage, Respond) that is designed to help the child’s communication partners provide AAC models in an easy, interactive format throughout the day.
