Providing small or inadequate portions of preferred materials such as blocks, crayons, or crackers is another way to arrange the environment to promote communication. During an activity the children enjoy, an adult can control the amount of materials available so that the children have only some of the parts that are needed to complete the activity. When the children use the materials initially provided, they are likely to request more. Providing inadequate portions of an interesting and desirable material creates a situation in which children are encouraged by the arrangement of the physical environment to communicate their needs for additional materials. For example, during snack time, an adult can encourage requests by presenting small servings of juice or pieces of a cookie rather than a whole cookie. A child who enjoys watching the teacher blow bubbles can be encouraged to make requests if the teacher blows one or two bubbles and then waits for the child to request more. When children initiate language with requests for more, the teacher has the opportunity to model and prompt more elaborate language as well as to provide functional consequences for the children's communicative attempts. For example:
Teacher: (Blows two bubbles and stops.)
Child: "More"
Teacher: "Blow more bubbles?"
Child: "Blow more."
Teacher: (Blows more bubbles)
Choice Making
There are many occasions when two or more options for activities or materials can be presented to children. In order to encourage children to initiate language, the choice should be presented nonverbally. Children may be most encouraged to make a choice when one of the items is preferred and the other is disliked. For example, the adult may hold two different toys (e.g., a big yellow dump truck and a small red block) and wait for the child to make a verbal or nonverbal request. If the child requests nonverbally, the adult has the option of prompting the child to verbalize ("Tell me what you want") or simply modeling a response for the child ("Yellow truck"). Children's verbal requests can be followed with expansions of their language ("You wanted the yellow truck") or models of alternative forms for requesting ("Yellow truck, please").
Assistance
Creating a situation in which children are likely to need assistance increases the likelihood that they will communicate about that need. The presence of attractive materials that require assistance to operate may encourage children to request help from adults or peers. A wind-up toy, a swing that a child needs help getting into, or an unopened bottle of bubbles are all examples of materials that can provide a nonverbal prompt to ask for help.
Sabotage
Setting up a "sabotage" by not providing all of the materials the children will need to complete a task (e.g., paints and water but no paintbrush following an instruction to paint), or by otherwise preventing them from carrying out an instruction, also will encourage them to make requests. This environmental strategy requires children to problem solve and indicate that something is wrong or missing. They must first determine what is needed, and this initial discovery may require prompts from an adult. The missing materials are cues for the children to communicate that something is not right or that additional materials are needed. Sabotage is an effective prompt for language when the cues are obvious and children's cognitive skills are sufficiently developed to make detection of the missing material easy and rapid. Sabotage should be carried out in a warm, engaging manner by the teacher; the episode should be brief and never frustrating to the child.
Silly Situations
The final environmental strategy is to create a need for children to communicate by setting up absurd or silly situations that violate their expectations. For example, an adult who playfully attempts to put a child's shoes on the adult's feet may encourage the child to comment on the absurd situation. During snack time, an adult can set up an absurd situation by placing a large piece of modeling clay or a colored block on a child's plate instead of a cracker, then waiting expectantly for the child to initiate a verbal or nonverbal request.
Children develop expectations for the ways things should be in everyday environments. They learn routines and expect that things will happen in a particular order. When something unexpected happens, they may be prompted to communicate. Of course, children must have expectations before the expectations can be violated. Thus, use of this strategy must be tailored to the individual skills of the children and to their familiar routines. For example, a child who always stores articles of clothing and materials in a specific "cubbie" will probably notice when an adult places a silly picture over it; a child who does not consistently use a specified "cubbie" would be unlikely to notice and respond to such a change in the environment.
