The research paper evaluated the effects of the Self-Regulated Strategy Development (SRSD) persuasive writing strategy called STOP & DARE on six 5th grade students, including three English Language Learners. Pre- and post-tests measured changes in students' use of persuasive elements, essay quality, and knowledge of STOP & DARE. Results showed significant gains in students' use of persuasive elements like rebuttals, transitions, and conclusions. Essay quality scores also moderately improved on average. Three students demonstrated particularly large improvements between 2.5-5 points in their writing scores. While two students scored slightly lower, overall the intervention improved students' persuasive writing abilities.
