Influence of Trend Estimation and Subject Familiarity on Practitioners' Judgments of Intervention Effectiveness.
Skiba, Russell; And Others
Journal of Special Education, v22 n4 p433-46 Win 1989
After special education resource teachers (n=27) were taught to use a standard trend estimation procedure as an aid in visual analysis of their students' charts, interrater agreement with reliability judges increased from .56 to .78. Prior knowledge of student performance was found to have an effect on visual inference. (Author/JDD)
