METHODS OF COMPUTING AND EVALUATING RESIDUAL GAIN SCORES IN THE READING PROGRAM.
RANKIN, EARL F., JR.; TRACY, ROBERT J.
THE "RESIDUAL GAIN" STATISTIC DEVELOPED BY MANNING AND DUBOIS IS PRESENTED AS A TOOL FOR THE MEASUREMENT OF INDIVIDUAL DIFFERENCES IN IMPROVEMENT RESULTING FROM TRAINING. RANKIN AND TRACY UTILIZED RESIDUAL GAIN MEASURES IN EVALUATING READING PROGRESS AND NOTED THEIR POTENTIAL AS A RESEARCH TOOL IN STUDYING CORRELATES OF READING IMPROVEMENT. IN COMPARING RESIDUAL GAINS WITH CRUDE GAIN (THE SIMPLE DIFFERENCE BETWEEN PRE- AND POST-TRAINING MEASURES), A DISCREPANCY IN GRADES ASSIGNED FOR IMPROVEMENT IN ALMOST HALF THE CASES WAS FOUND. CRUDE GAINS TENDED TO UNDERESTIMATE THE PROGRESS OF SUPERIOR IMPROVERS (AS MEASURED BY RESIDUAL GAIN) AND TO OVERESTIMATE THE PROGRESS OF INFERIOR IMPROVERS. TWO COMPUTATIONAL FORMULAS OF PRIMARY INTEREST TO THE RESEARCHER, THE Z-SCORE METHOD AND THE RAW SCORE METHOD ARE PRESENTED WITH DESCRIPTIONS OF THEIR ADVANTAGES AND DISADVANTAGES. A COMPUTATIONAL METHOD FOR EVALUATING RESIDUAL GAINS IN TERMS OF DERIVED SCORES BASED ON THE NORMAL DISTRIBUTION CURVE IS DESCRIBED. A SHORT GRAPHICAL METHOD FOR ASSIGNING EVALUATION CATEGORIES TO RESIDUAL GAINS IN THE CLASSROOM IS PRESENTED. THE METHODS FOR ESTIMATING AND EVALUATING RESIDUAL GAINS WITHOUT LABORIOUS CALCULATION SHOULD MAKE THE TECHNIQUE AVAILABLE TO READING TEACHERS WITH AN ELEMENTARY KNOWLEDGE OF STATISTICS. THREE REFERENCES ARE INCLUDED. THIS ARTICLE APPEARED IN "JOURNAL OF READING," VOLUME 10, MARCH 1967. (RH)
