Abstract:
|
Classrooms are rated on the effectiveness of instructions given to students. A rater rates the effectiveness scores on n instruction items in a classroom. Cost constraint prevents each of available KB raters from rating all JB classes. Instead, K raters are randomly assigned to a block in which each rater rates J classrooms in the block. This design creates B incomplete blocks. This paper finds a design of an experiment that leads to an optimal choice for n, J, K and B to yield consistent ratings of classroom instructions.
