Action research was conducted to determine if explicit phonics instruction would bridge the gap between students and their grade-level peers. Fourth and fifth-grade students were taught for six-weeks utilizing Really Great Reading’s HD word program. Grade-level fluency probes were used to monitor student progress at the beginning and end of the six-weeks as well as the Diagnostic Decoding Survey (DDS). Findings concluded that all students’ fluency improved on their correct words per minute and accuracy as well as on the DDS. Further research would be needed to determine how long it would take for students to close the gap between them and their grade-level peers.
