Show moreThe relationship between enactment of Common Core State Standards – Mathematics (CCSSM), student misconceptions, student achievement and teacher variables was investigated. After providing professional development on CCSSM enactment, observations were conducted to determine the degree of enactment of CCSSM content and Standards for Mathematical Practice (SMP) in 22 classrooms of nine teachers in an urban charter school network consisting of three high schools. Students were all boys, 98% African American, and predominantly of low socio-economic status. Data included quarterly assessments, Partnership for Assessment of Readiness for College and Careers (PARCC) test scores, and a teacher survey. Results indicated experienced teachers with high efficacy who expected students to discuss their work were related to higher levels of CCSSM enactment in teacher actions, fewer misconceptions and higher test scores. Newer teachers were most concerned about availability of CCSSM materials and had higher levels of enactment of CCSSM in classroom materials. A strong belief in student ability was related to student enactment of SMP. Implications for teacher education, teacher practice, and future research are discussed.
