Contribution of the Study to Gifted EducationThis study has demonstrated how a single-subject reversal (ABA) design can be used in the field of gifted education to demonstrate the effectiveness of an intervention recommended in the literature. The advantages of the research design are that the experiment could be carried out relatively easily, with recruitment and testing taking a relatively short period of time. The actual implementation of the research took a period of 4 weeks, and a documented effect could be determined after this period. No control group was needed, as the subject acted as her own control through the collection of baseline data.Perhaps most interesting is that even a child of advanced verbal ability will not readily demonstrate his or her higher level language ability when given lower order questions. This idea clearly challenges the idea that a child-centered, open-ended curriculum is all that is needed in the early child- hood context to challenge and develop children with advanced language abilities. Although there have been calls for higher order thinking skills to be taught to young gifted children, there is no research that has demonstrated the ways in which young gifted children respond to higher order thinking questions in the preschool or child care setting. This preliminary study provides a useful platform for building an evidence base for the effectiveness of this type of intervention with young potentially gifted children.
