Policy efforts in mathematics have focused on increasing teachers' mathematics content knowledge (MCK), with the goal of increasing teacher quality and in turn increasing student mathematics learning. An alternative approach to increasing student mathematics achievement is to investigate curricula that can be effectively used by teachers with a range of MCK. Drawing from a large-scale study of kindergarten students (n = 2,598) and their teachers (n = 130), the current study investigated the interaction between teacher MCK and curriculum (Early Learning in Mathematics core kindergarten curriculum vs. business-as-usual curricula) on (a) instructional behaviors and (b) student mathematics achievement gains. Results indicated differential significant interactions across instructional behaviors and a small but negative effect of teacher MCK on student mathematics achievement gains. Implications for future research, policy, and practice are discussed.

The Advanced Placement Computer Science Principles (APCSP) course was introduced in 2016 to address long-standing gender and racial/ethnic disparities in the United States among students taking Advanced Placement Computer Science (APCS) in high school, as well as among those who pursued computing majors in college. Although APCSP has drawn a more diverse population of course takers than the traditional Advanced Placement Computer Science A (APCSA) course, questions remain about whether the new course portends students' longer-term interest in computing and technology. This study used data from more than 120,000 first-year college students in the United States to understand the relationship between taking APCSA, APCSP, or both APCS courses and students' aspirations to major in computing or to pursue a computing or technology career. Our results indicated that taking APCSA or taking both APCS courses positively predicted students' major or career aspirations in computing and technology, but that taking only APCSP did not predict long-term computing interest (although positive associations were identified for women). The findings identify a possible tension in the function of APCSP, as it appears to broaden access to computing knowledge, but may not necessarily encourage longer-term computing aspirations for all groups of underrepresented students.

AbstractWe report findings from qualitatively analyzing audio recordings and teacher-generated products from a two-day in-person collaborative design (co-design) workshop where nine experienced high school CS teachers revised parts of an existing introductory high school program toward justice. In response to our research question of how teachers demonstrated agency as co-designers, our analysis revealed that they collaboratively questioned the purpose, the “why,” and the approach, the “how,” and captured ideas in lesson templates and unit descriptions to transform future practice. We discuss co-design with teachers as openings to explore nuances of teachers’ visions for equitable CS education. We highlight the foundational longstanding relationships and politicized trust, and enabling features of the co-design space for equitable participation and joint creation of boundary objects to sustain ideas.
