A RESPONSE TO GILLMORE AND STALLINGS REGARDING A PAPER BY NEDLER AND SEBERA (1971).

Gillmore and Stallings criticize Nedler and Sebera's paper in terms of the experimental design, statistical analysis, and data errors in the report. I am responding because responsibility for the research design and analysis of the project in question was mine. To provide some context: Mrs. Nedler was responsible for developing the Early Childhood program reported on in the paper. She was assisted by a staff of about 12 professionals, including three teachers. Mrs. Sebera's responsibility was for testing and other data-gathering functions called for in an evaluation design developed by the Research and Evaluation Division, Southwest Educational Developmental Laboratory (SEDL), which I directed. That R&E staff included about 25 professionals, four of whom were statisticians. In October 1962 the R&E division published a complete evaluation report, wherein the project was described and results were reported. Neither Mrs. Nedler nor Mrs. Sebera has responsibility for the evaluation design, analysis, or report, although both were involved. However, Nedler and Sebera (hereafter, N & S) based the article in question on their own experiences and knowledge of the evaluation design and analysis described in the October 1969 report.
