What The SRSD Research Tells Us
Steve Graham: At the present time there's about 100 studies taking a look at the effectiveness of SRSD. They've all been successful in the sense that student's performance has improved. One of the things that's happened over time is who's been involved in those studies have really ranged. Starting with kids mostly with learning disabilities, preceding the kids with ADHD, kids who have emotional behavioral problems, kids w sever cognitive problems, but also a lot of work with kids in general.
Barbara: We started with the upper elementary school student, the third, fourth, fifth, sixth grade. Most of the research in those early years were in that elementary level, and then as doctoral students came through Karen and Steve's programs and began to do their own research, there started to be more research on the middle school student, the high school student, and now even at the college level. The research has expanded to show that this same exact structure and strategy works for all ages.
Debra: Steve Graham and Shar Kiuhara, Karen Harris and myself conducted a meta analysis of writing intervention research. This essentially means that we went out and collected all o the research papers that have been published. What we found is that SRSD has the highest effect size of any writing intervention out there.
Karen Harris: It has been recognized in writing next as having the single largest effect of any research to approach to writing instruction. There are many things out there yet that have not been researched. We tend to get effect sizes that are Steve Graham likes to call them dancing on the moon size.
Steve Graham: What you're usually looking is about a full effect size or 1.0, and 99 out of 100 studies, it's been effective. What are the chances of 99 out of a 100 studies resulting in improved writing performance if it wasn't effective. We also see what kids write, so that's the other way without a number on it, we see where they start, we see what they do at the end, you show that to teachers, it's pretty obvious.
Robert Reid: SRSD is scientifically based. It's based on 50 years of research and cognitive science and educational psychology, and every element in SRSD is based on sound cognitive science. So you really shouldn't be surprised that it works.
