Rj. Pritchard et Jc. Marshall, EVALUATION OF A TIERED MODEL FOR STAFF-DEVELOPMENT IN WRITING, Research in the teaching of English, 28(3), 1994, pp. 259-285
This study sought to determine the value of a tiered model of staff de
velopment for five districts using Teacher Consultants (TCs) drawn fro
m a parent district with a long writing project history. In these outr
each projects, these TCs actualized the National Writing Project (NWP)
principle of regarding teachers as expert consultants to their collea
gues. Stake's Contingency and Congruence Evaluation Model was used to
establish 1) the relationships among the preconditions necessary for s
uccessful implementation of the staff development program, 2) the proc
esses by which the program was to be implemented, and 3) the outcomes
which were intended. Data across five replication sites consisted of e
valuations from 366 participants; self-reports of changes in skill lev
els by 191 participants; self-reports of classroom practices implement
ed by 216 participant and control teachers; and pretest and posttest s
cores on essays written by 3,927 students of participant and control t
eachers. It was determined that most required preconditions were obser
ved; that all intended processes of the programs in the replication si
tes were successfully accomplished; and that the expected outcomes in
replication sites were, in fact, achieved. In terms of outcome data, m
ost of the analyses reflect significant differences in writing achieve
ment between treatment and control subjects, favoring students of trai
ned teachers. A survey of classroom practices indicated that trained t
eachers at all levels implemented more varied composition activities t
han did non-trained teachers. The results are viewed in light of the l
iterature on effective staff development and, in particular, on the NW
