The Effects of a Computerized Taped Intervention on the Accuracy of Letter Identification

Letter names are some of the many preschool accomplishments that are of particular relevance to later academic challenges. However, many children enter school without having fluent letter name knowledge. The current study evaluated the effects of a taped-letter (TL) intervention delivered through PowerPoint on the accuracy of letter identification in three young children using a multiple probe across participants design. The participants were trained to say the letter name when the PowerPoint provided a printed letter on the screen and to echo the computer model of the correct response. Each training was followed by an assessment in which the participant was tested on letter identification accuracy. The TL intervention was successful in increasing letter identification to at least 23 letters for all participants within 8-11 intervention sessions. These results extend and add to the findings of previous studies demonstrating the effectiveness of taped interventions in teaching academic skills and demonstrate that similar taped interventions can be easily developed to teach early academic skills using a computerized platform.

This study evaluates the effectiveness of a taped-letter intervention delivered through PowerPoint in improving letter identification accuracy in preschool children. The results show that the intervention successfully increased letter identification for all participants within 8-11 sessions, demonstrating the potential of similar taped interventions in teaching early academic skills.
