Small group instruction has several benefits according to research. It allows teachers to better meet the individual needs of students and provides more opportunities for feedback and scaffolding of lessons. Research shows it can improve self-esteem and academic achievement. Effective small group instruction consists of grouping students flexibly according to their skills and needs, focusing instruction on areas like decoding, comprehension and vocabulary. Lessons involve strategy instruction, reading practice, discussion and assessment to evaluate progress. Teachers use data from assessments to form initial groups and determine instructional focus.
