This report describes a process for increasing primary students' reading comprehension skills through the use of a guided reading program. The targeted population consisted of primary students in a northwest suburban area of a large city in the Midwest. The problems of poor reading comprehension scores were documented through the use of the Gates-MacGinitie Reading Tests and end of selection tests. Analysis of probable cause data revealed that students are lacking basic reading comprehension skills. Analysis of Guided Reading for Teachers Survey revealed inconsistent use of guided reading end of selection tests, fall and spring assessment and graphic organizers. Increase of English as a Second Language population has revealed low reading comprehension scores among these students. A review of solution strategies suggested by knowledgeable others, combined with an analysis of the problem setting, resulted in the selection of two major categories of Guided Reading Intervention: consistent use of graphic organizers and end of selection tests. Post intervention data indicated an increase in student reading comprehension skills through the use of graphic organizers and a guided reading program. Appendixes contain the teacher survey, a guided reading checklist, a sample end of selection test, and a consent letter. (Contains 40 references and 7 figures.) (Author/RS)
