Effectiveness of a self-instructional program to prepare home economics teachers to teach pupils to apply generalizations

The purpose of this experiment was to determine the effectiveness of a self-instructional program to prepare home economics teachers to teach pupils to apply given generalizations. The criterion of effectiveness was a paper and pencil test in two equivalent forms developed to measure the ability of pupils to apply generalizations. One test was administered by the researcher immediately following the teaching of a three-week foods unit which was limited to generalizations concerning the preparation of vegetables, quick breads, and starch sauces and puddings to a ninth-grade home economics class. An equivalent form of the immediate post test was administered by the researcher three weeks later to test retention. The immediate post test had a coefficient of reliability greater than .91 determined from scores of 104 ninth-grade pupils. The product moment coefficient of reliability between the two tests was .95
