Setting
The study took place in Grade 3 classrooms across four academic years in a metropolitan school district of the Southeast United States. SBI classroom instruction was implemented at the classroom level, and SBI tutoring was implemented in small groups.
Study sample
Of the 243 AR students in this contrast, 46 percent were female, 75 percent were eligible for subsidized lunch, 64 percent were African American, 28 percent were European America, and nine percent identified as other. Also, seven percent were Hispanic, two percent were English language learners and 12 percent were in special education. All students in this contrast were at-risk for mathematics difficulties.
Intervention Group
The intervention in this contrast (Tier 2 SBI tutoring) included instruction in small groups of 2 to 4 students. Three 20-30 minute tutoring sessions were conducted each week (totaling roughly 940 minutes across all session). The intervention took place after the general math problem solving unit was taught in the regular classroom. The content in the Tier 2 intervention mirrored the content in the Tier 1 classroom, but the Tier 2 intervention was more targeted on the most difficult concepts, used more manipulatives, included more opportunities for scaffolding to support student learning, and taught students self-regulation strategies. The sessions had four 3-week units, with each unit addressing a specific problem type (shopping list, buying bag, half, and pictograph). Each unit began with 5 sessions of instruction that covered the underlying concepts and structural features of the problem type and used concrete objects. The students and instructor would explain together why and how they used each step in a solution strategy. Over time the students worked on problems independently. In sessions 6-9, the problems now varied in cover story and had transfer features (different question or irrelevant information). Self-regulation strategies were included in the intervention during some of the cohorts but not all.
Research assistants served as the tutors.
Comparison Group
Students in the control group for this contrast did not receive SBI Tier 2 tutoring. Some of them did receive SBI Tier 1 classroom instruction (but some did not).
Support for implementation
All research assistants (RAs) received a one day training session that provided with instructions, demonstrations, and scripted materials to study. RAs then practiced in pairs before conducting one lesson for a project coordinator who graded the delivery of the instruction. RAs were also given a three-hour training before the start of each unit, and all sessions were audiotaped from which RAs received corrective feedback.
