Use of I-Ready in Tiered Instructions for ESL Students: A Quantitative Case Study

The objective of this study was to investigate the effects of implementing tiered instructions in conjunction with the I-Ready online program on the academic advancement of English as a second language (ESL) learners. The research utilized a quantitative case study design to examine the diagnostic test scores at the one academic year’s commencement, midpoint, and conclusion. The RAT framework assisted the investigation. Data was obtained from a sample of 45 ESL third-grade students. Students in Tier 1 who needed further assistance in achieving proficiency standards were allocated to small groups during the regular lesson. In contrast, students in Tier 2 were provided with a multi-tiered system of support (MTSS) block with a different teacher, and Tier 3 students were assigned to the learning lab for the personalized I-Ready lessons. The study’s findings revealed that implementing tiered instructions significantly enhanced students’ academic performance. Superior outcomes were achieved in phonics, high-frequency words, and vocabulary. This research study has contributed to the advancement of ESL teaching and learning by providing a foundation for future investigations into the efficacy of the online tiered approach in aiding ESL students.
