Characteristics of study sample as reported by study author.
| White | 100% |
The study intervention took place in a secondary school in Florida, via an online tutoring system that connected the students to an instructor at a local university. The intervention occurred during a study hall period immediately after lunch.
The study sample included four secondary school students who had been diagnosed with LD. All four students were White. Damon was a 14-year-old male in eighth grade; Carson was a 15-year-old male in ninth grade; Jake was a 16-year-old male in tenth grade; and Monica was a 13-year-old female in sixth grade.
SRSD was used to teach students strategies for both planning and writing. An undergraduate research assistant delivered the instruction via online chatting and video conferencing through the use of Adobe Connect and Google Docs. The structure of the intervention included up to five lessons, where the fifth lesson would be repeated if the student did not meet prespecified criteria. Students were taught how to use the “POW+TREE” mnemonic strategies. POW reminded students to pick ideas, organize information, and then write and check their work. TREE prompted students to think of a topic sentence, reasons, examples, and an ending. During training, students could also earn points towards reinforcers. These reinforcers were described as “items valued at two dollars or less.” A preference assessment was used to develop a list of reinforcers, based on students’ preferences. Post-training essay probes were administered immediately following SRSD instruction.
The study uses a multiple probe design across participants. During the baseline condition for each student, teachers taught their classes as usual.
The tutor received 4 hours of training in applying the instructional procedures of SRSD.
An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
