Presented in two reports, this study on reading comprehension investigated whether expository passages with adjacent-to-text activities facilitate the learning of reading comprehension skills at the same time that they improve comprehension of text content, and whether written feedback increases the effectiveness of adjacent-to-text activities. Good, average, and poor readers in a combination fifth-sixth grade classroom were randomly assigned to participate in adjacent-to-text activities, adjacent-to-text activities with the use of an answer key, or reading only the text (control). Activities were designed to develop the Level E Skills identified for the "Wisconsin Design for Reading Skill Development." This second report contains the following six appendixes: the environmental reader called "Life in the Ecosystem," used in the study, the adjacent-to-text activities for each unit, a list that classifies each activity according to the skills and objectives of the Level E test, the answer keys, the content comprehension tests, and directions for the students participating in the treatment groups.
