A workshop with virtual consultation practice-based professional development model for self-regulated strategy development persuasive writing instruction was evaluated in a randomized controlled trial. Nineteen general education teachers and 564 Grade 5 and 6 students in 16 low-wealth rural schools participated. Following training, teachers provided instruction in their inclusive classrooms. Results indicated that students receiving instruction improved in the number of persuasive elements and words written when compared with students in the control group. Differences in element type were evaluated with largest effects noted for reasons and explanations. Student group differences were noted with nonstruggling students having greater gains than struggling students.
