A study determined the effect of shared writing activities on reading comprehension. The subjects, 40 second- and third-grade students from a suburban school in Mercer County, West Virginia, completed the Reading Comprehension Subtest of the Comprehension Test of Basic Skills (CTBS) for grade 2 as a pretest. A control group of 20 students were instructed throughout a 6-week period in a literature-based classroom where activities were limited to a basal format. The experimental group of 20 students also engaged in the same literature; however, they were also instructed in a wide range of writing activities. The experimental group did score significantly higher then the control group on multiple-choice responses based on a variety of comprehension questions. Results indicated that students who practiced and strengthened their comprehension skills by using writing activities displayed a difference in comprehension skills measured by a multiple choice format.
