Criterion and Independent Variables and the Precision Indexes of These Variables as Used in Establishing a Formula for Predicting Reading Difficulty of Programmed Materials in Fourth Grade Science.
Shaw, Robert Arley
Developed was a procedure to determine the reading difficulty of fourth grade programed science materials. The materials used consisted of three units of programed science materials; the pupil sample consisted of 599 elementary school children in grades 4, 5, and 6. A regression analysis procedure was used to establish a readability equation, and various sampling techniques were set up to determine if the independent variables could be stabilized under the given sampling procedures. The criterion variable was validated by correlating the counts on this variable with five measures of achievement and an IQ score. Reliability of the error count was determined from past research. Concluded were the following: (1) the established equation was considered the best predictor of the reading difficulty of the materials under investigation, (2) the error count had some validity as a criterion variable in determining reading difficulty, (3) the programed materials satisfied the assumptions of good sequential development which were listed in the study, (4) the sampling procedure s used in this investigation did not serve to stablize all of the variables, and (5) for valid counts on the variables the total sample should be used, and to obtain measures on the total sample of material a computer is necessary.
