The Intrinsic and Extrinsic Value of Instrumental Music Instruction on Standardized Mathematics and Reading Scores of Third-Grade Students Colleen Rigot May 2004 The purpose of this study was to determine if third-grade students who attended string instruction in a pull-out program from academic studies for sixty minutes a week would show any measurable gains in reading and mathematics scores on standardized testing (based on scores from the Comprehensive Test of Basic Skills (CTBS) in grade two compared to scores from the Maryland School Assessment (MSA) in grade three). This study involved use of a pre-post causal comparative design to compare MSA reading and mathematics normal curve equivalent (NCE) scores of students from two groups over a one-year period with CTBS scores from the previous year. Achievement gains of students involved in the string program were greater than those of non-string students, although the difference was not statistically significant. Research in areas related to the impact of arts instruction on student achievement should be ongoing as the arts continue to defend their place in the core curriculum of schools.
