M. Gettinger, EFFECTS OF INVENTED SPELLING AND DIRECT INSTRUCTION ON SPELLING PERFORMANCE OF 2ND-GRADE BOYS, Journal of applied behavior analysis, 26(3), 1993, pp. 281-291
Four second-grade boys, 2 rated by their classroom teacher as below av
erage and 2 as above average in basic language skills, participated in
a 16-week spelling investigation. The participants alternately receiv
ed, in counterbalanced order, 5 weeks of an invented spelling approach
that incorporated 15-min creative writing periods and 5 weeks of dire
ct instruction that involved 15-min periods of guided practice on spel
ling word lists. At the end of 10 weeks, each condition was replicated
for 3 additional weeks. Although direct instruction resulted in more
targeted words spelled correctly, invented spelling resulted in more n
ontargeted words spelled correctly, higher preference ratings by child
ren, and higher teacher ratings of the quality of 3 of the children's
writing samples.
