Two approaches to spelling instruction were compared by measuring which program was more successful. Thirty-two fourth-grade students participated; instructional intervention spanned 6 months. The control group used the materials and procedures of the Macmillian Basal Series. The experimental group used the Spelltex Individualized Spelling Kit. The results of each program were measured by using the California Test of Basic Skills, Level 1 spelling test for grade four. The means of the two groups were compared by using a "t" test. Results indicated: (1) no significant difference between the total group of students using the individualized approach and the total group of students using the basal series; (2) no significant difference between the girls in the control group and the girls in the experimental group; and (3) no significant difference in spelling abilities between the boys using the Macmillian Basal Series and the boys using the Spelltex Individualized Spelling Kit. (Eight tables of data and 38 footnotes are included; 38 references, a list of the steps in the individualized plan, the 5-day basal speller plan, and 6 tables of data are attached.) (RS)
