description: Children in care (e.g., foster care) are at risk of a variety of negative developmental outcomes. Of particular concern are their often poor academic outcomes. Indeed, children in care often have below grade-level performance on math and reading, increased rates of school drop out, and learning disabilities. Despite these difficulties, relatively little research has been conducted to try to ameliorate the problem. The present thesis, consisting of three independent randomized controlled trials (RCTs), sought to address the need for improved educational outcomes for children in care. The first RCT was an evaluation of a one-on-one tutoring program, TutorBright. Children in care were randomized to either a tutoring group or a waitlist control group and assessed on their math and reading skills, as well as on other educationally relevant domains (executive functioning, behaviour, and caregiver involvement in school-related activities), pre and post test. ANCOVA via multiple regression revealed that the children in care that had received tutoring, compared to the waitlist control group, made significantly greater gains in reading comprehension (Hedges’ g = 0.34), reading fluency (g = 0.16), and math calculation (g = 0.39). Moreover, executive functioning and self-reported symptoms of PTSD (for older children) were significant moderators of the effects of tutoring. No significant spill-over effects of tutoring were found. The second RCT, building upon previous RCTs by Flynn et al. (2012) and Harper and Schmidt (2016), evaluated whether a shorter version (i.e., 15 weeks) of a one-on-one Direct Instruction tutoring program, Teach Your Children Well (TYCW), was as effective as a longer version of TYCW (i.e., 25 weeks) on improving the math and reading skills for children in care. ANCOVA via multiple regression did not reveal any significant group differences in academic performance for any of the WJ-III subtests. Collapsing across the two intervention conditions, follow-up paired samples t-tests revealed significant improvement in Letter-Word Identification (Cohen’s d = 0.22), Reading Fluency (d = 0.36), Calculation (d = 0.38), Math Fluency (d = 0.47), Applied Problems (d = 0.30), and Broad Reading (d = 0.30) and Broad Math (d = 0.40) composite scores, suggesting that the 15-week and 25-week TYCW programs were equally effective in improving math and reading skills. Moreover, an attribute-treatment interaction analysis revealed that children with higher executive functioning benefited more from the shorter tutoring dosage for Calculation. The third RCT was a small pilot study that aimed to assess whether working-memory training (WMT) can enhance: 1) working memory capacity, in the short and longer term (i.e., immediately following the completion of WMT and 6-months later), 2) symptoms of Attention Deficit Hyperactivity Disorder (i.e., inattention, hyperactivity, and executive functioning) in the short and longer term, and, 3) math and reading skills at 6-months post WMT. The findings from this study suggested that WMT can improve verbal working memory (g = 0.35) as well as visuo-spatial short-term memory (g = 1.10) in the shorter term but not in the longer term. Moreover, WMT did not have a significant impact on improving symptoms of ADHD or math and reading skills. Together, the results of this dissertation indicate that the math and reading skills of children in care can be improved via tutoring. The findings highlight the importance of providing children in care with effective academic supports in order to help them reach their full potential.
