迪肯代写Essay:CTD

       The study concluded that CTD was effective on sight words to all participants but since this was a group trial each child's performance differed. All the participants increased with intervention prompts but with individual response they remained in the low levels. The study supports previous studies that constant time delay is effective with one-to-one instruction but can be implemented in small group instruction successfully (Wolery, Ault, Gast, Doyle, & Mills, 1990).Reading Racetrack is a method for teaching sight words as well as reading. It uses a game style racetrack which the child has to follow to the finish line. Hyde, McLaughlin, & Everson, (2009) replicated a study with two elementary children in the Pacific Northwest. The children, one female in the sixth grade and one male in the fifth grade, both met state and federal criteria for learning disability and received services in a resource room for reading and writing (Hyde, McLaughlin, & Everson, 2009).  The materials used in the study were Dolch Sight word sets 3-4, a stop watch, graph paper, pens, data collection sheets and drill sheets designed as a race track. The sight words were placed on the racetrack randomly so no similar words were together. Two 28 cell racetracks were used, racetrack one had seven sight words repeated in random order and racetrack two was a review racetrack for 28 previous words and this reinforced previous learning (Hyde, McLaughlin, & Everson, 2009).
