Study Details
Setting
The study took place in Davidson County, Tennessee. The language sessions were administered in the children’s classrooms or a nearby therapy room.
Study sample
Forty students with developmental delays participated in this study. The students were from two schools, a university-based preschool and a public school. The students from the university- based preschool had developmental delays of at least 20% of their chronological age in at least one developmental area on the Denver Developmental Screening Test. The students from the public school had scores more than one and one half standard deviations below the mean on four out of seven developmental areas. The 40 students were randomly assigned to two conditions: 20 received instruction with the milieu teaching method, and 20 received instruction with the communication training program.
Intervention Group
Milieu teaching is a naturalistic instruction method whereby the trainer follows the lead of the child in determining when to teach and what language form to elicit. In milieu teaching, the environment is arranged to include objects and activities that interest the child. Instructional strategies including incidental teaching and time-delay are utilized to encourage child communication. The goal of the milieu teaching method is that children learn to comprehend language structures from natural and informal adult modeling and active communication about the object or activity that is of interest to the child. When a child produces targeted language behavior during the activities, those utterances are consequated according to the child’s interest. For example, if a child requests a toy, giving the toy to the child serves as a functional consequence of the behavior. For students in both conditions, developmentally appropriate language targets were selected from the communication training program as the goals for the intervention. Children were separated into groups of two or three, and the sessions lasted 10 minutes per child. The treatment lasted for 60 sessions. The first half of each session consisted of a group activity (games, making collages, etc.); in the second half of the session, children could choose toys of interest to them from the variety of toys available.
Comparison Group
The comparison condition consisted of another treatment, called communication training. Communication training involves a more structured drill-and-practice approach than the naturalistic approach espoused by milieu teaching and uses a predetermined set of rules to select the trials and language targets. Comprehension of language targets was taught explicitly in this condition rather than implicitly in milieu teaching. The communication training group used consequences that included verbal feedback and tangible rewards to increase the likelihood of child response. For children with more significant disabilities, the rewards sometimes were not tied directly to a child’s utterance. The sessions were conducted for similar amounts of time and with the same numbers of students in both the intervention and comparison conditions.
Outcome descriptions
Nine eligible outcomes were assessed in this study, and all fall within the communication/ language competencies domain. For a more detailed description of these outcome measures, see Appendix B.
Support for implementation
All language teachers received 12 hours of group training. They also received individual and small-group training (ranging from two to ten hours depending on their entry skills, abilities in executing their assigned method, and the children’s specific needs). During the intervention period, the language teachers were observed on a weekly basis, and weekly group meetings were held to support teachers and solve training and behavioral management problems.
An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
