This booklet summarizes forty-two Initial Teaching Alphabet (i.t.a.)research reports, highlighting the major features of each study. With minor variation, usually resulting from an absence of complete information, each abstract indicates the number and type of students involved, their grade level, and how they were assigned to experimental or control groups. The reading materials used by each of the groups, the comparability and specific training of teachers, as well as how they were assigned to classes are cited where possible. This information is followed by a list of the evaluation instruments used, the duration of the study, and the percentage of students who made the transition to traditional orthography at the time they were tested. In each abstract, results are summarized with references to the administration of instruments or final observations based on the children's ability to read in traditional orthography. (WR)
