Theory and Practice in Teacher Education Publications and Other Works

Document Type





A professional development (PD) program for Strategic and Interactive Writing Instruction (SIWI) integrating effective PD features was implemented with teachers over three years. Using a one-way analysis of variance (ANOVA), it was examined whether length of participation in PD impacted knowledge and ability to faithfully implement. Findings indicate significant improvements with each year of PD; those who participated for three consecutive years received the highest possible ratings on knowledge as measured by the Levels of Use (LOU) and instruction as measured by the SIWI observation and fidelity instrument. Additionally, because of modifications to the PD program, it was examined whether the year of one’s PD involvement impacted outcomes. Findings reveal that outcomes were strongest during the last year when SIWI mentors were present.
