The persistent challenge of foundational literacy acquisition necessitates targeted interventions. This case study examines the implementation and outcomes of a phonics-focused reading intervention at Oakwood Elementary School, targeting a cohort of first-grade students identified as reading below grade level. The intervention, delivered over one academic semester, aimed to improve decoding skills, phonemic awareness, and overall reading fluency through explicit, systematic instruction. The central thesis is that a structured, phonics-intensive approach, when delivered with fidelity and supported by ongoing assessment, can significantly enhance the reading proficiency of struggling first graders.
Oakwood Elementary initiated the intervention in January 2023, selecting 15 students from three first-grade classrooms who demonstrated low scores on the DIBELS (Dynamic Indicators of Basic Early Literacy Skills) assessment, specifically in areas of phoneme segmentation and non-word decoding. The intervention group received 30 minutes of small-group instruction daily, separate from their core literacy block. This instruction was delivered by a reading specialist trained in Orton-Gillingham principles. The curriculum emphasized direct teaching of letter-sound correspondences, blending sounds to form words, segmenting words into sounds, and practicing with decodable texts. For instance, early lessons involved daily drills on the sounds of consonants like 'm', 's', and 't', followed by blending exercises to form words such as "mat," "sat," and "tam." As the semester progressed, the instruction moved to digraphs (e.g., 'sh', 'ch') and short vowel patterns, with students regularly reading passages containing only words that aligned with the phonics skills taught.
Student progress was monitored bi-weekly using the same DIBELS measures used for initial identification, alongside informal running records and teacher observation logs. A comparison of pre- and post-intervention DIBELS scores revealed a statistically significant improvement in the intervention group's average score, particularly in the phoneme segmentation fluency (PSF) and nonsensical word fluency (NWF) subtests. For example, the mean PSF score increased from 15 correct sounds per minute to 38, and the NWF score rose from 10 correct sounds per minute to 29. This suggests that the explicit phonics instruction directly addressed and improved the students' ability to manipulate sounds within words and decode unfamiliar words. Anecdotal evidence from the reading specialist and first-grade teachers also pointed to increased confidence and engagement among the participating students during regular classroom reading activities. One student, previously reluctant to read aloud, began participating actively, demonstrating improved word recognition and less hesitation.
Despite the positive quantitative and qualitative results, the intervention faced several practical challenges. Class scheduling proved difficult, occasionally requiring students to miss other subjects. Furthermore, ensuring consistent fidelity to the Orton-Gillingham approach across all sessions required careful planning and professional development for the reading specialist, especially when addressing the diverse needs within the small group. The limited availability of decodable texts that precisely matched the targeted phonics skills also presented a minor hurdle, necessitating some adaptation of materials. Nevertheless, the study's findings at Oakwood Elementary support the hypothesis that a targeted, phonics-based intervention can be a powerful tool for remediating reading deficits in early elementary grades. The gains in decoding and phonemic awareness provide a solid foundation for further literacy development.
