Iterative Evaluation: NRS. An Example.
Leinhardt, Gaea; Engel, Mary
The use of increasingly more informative evaluations of a single innovation are documented. The innovation, The New Primary Grades Reading System (NRS), was implemented in a variety of settings, and the evaluations track the implementation from the early stages of pilot testing through large-scale adoption of the program. NRS is characterized as an eclectic code-breaking approach to beginning reading instruction as opposed to a whole-word approach. It employs letter-sound correspondences, synthetic phonics, analytic phonics and linguistic techniques such as displaying differences and similarities in spelling patterns. NRS is both individualized and adaptive. Once all the students are at or above Level III and receiving instructions from audio cassettes, the teacher is free to"travel" around the room to diagnose, prescribe, teach and monitor student progress and to assess student performance. Many studies of the effectiveness of NRS have been conducted. A sample of seven of the 20 or more studies are reported here. There is one within-school study, five within-district across-school studies, and one across-district study. In all cases there is pre/posttest information on grade 1 students. Cumulation of evidence across settings allows for greater confidence in conclusions drawn from the evaluation. (Author/RL)
