pdf The Effect of the Intensity of Spelling Instruction of Elementary Students At Risk for School Failure Popular

This study examined the effects of varying intensity of the Direct Instruction program, Spelling Mastery, over a four-week summer remedial program for elementary students. Students received either two lessons a day (for a total of 36 lessons) or one lesson a day (18 lessons). No significant differences between groups were found on standardized measures or curriculum-based measures following intervention; however, all students demonstrated statistically significant growth in spelling skills, as measured by curriculum-based probes.
