Keithley Sizemore, Elizabeth, "A Phenomenological Study of Differentiated Instruction for Fifth Grade Gifted and High Ability Learners through Math in Focus" (2015). Doctoral Dissertations and Projects. 1089.
his phenomenological study investigated the differentiation techniques implemented for gifted and high ability learners by fifth grade general classroom mathematics instructors utilizing the Math in Focus (Great Source/Houghton Mifflin Harcourt, 2009) Singapore Mathematics program in a suburban school district. To provide an understanding of the differentiation process currently being implemented by general classroom mathematics teachers, six participants completed an open-ended questionnaire and two representative participants were interviewed, observed, and asked to provide artifacts for analysis in the study. Data analysis using transcendental phenomenological reduction, including bracketing and horizonalization, revealed several overarching lessons. Participants analyzed multiple student data sources throughout the planning and implementation stages of providing differentiated instruction to identify students’ levels of readiness and appropriate task complexity. Flexible small groups were utilized to meet individual student needs through content differentiation. Diversity in enrichment and assessment resources, as well as targeted professional development and planning time were identified as necessary to improve the process of providing differentiated instruction.
