The purpose of this study was to assess the impact of a school division policy on early algebra on students' course taking patterns in high school. Over the past two decades, there has been significant growth in the number of students taking Algebra 1 in middle school. Research about the advantages and drawbacks to completing Algebra 1 prior to high school have mixed conclusions, with some suggesting that students benefit from the opportunity to take more advanced mathematics and science courses in high school and others concluding that students are more likely to fail and need to repeat courses if they take Algebra 1 early (Stein et al., 2011). Most of the research has focused on students taking Algebra 1 in eighth grade. At the same time, there is an ever-growing group of students seeking to take Algebra 1 even earlier, as evidenced by expansive growth in the number of students accessing Advanced Placement Calculus prior to twelfth grade (College Board, 1997; College Board, 2017). To assess the impact of early Algebra 1, the researcher considered transcript data for two cohorts of students in a large, suburban school district who took Algebra 1 in seventh or eighth grade. Statistical analysis was performed to assess whether students were likely to access the highest level mathematics courses available to them, whether they were staying in mathematics courses throughout all years of high school, and what patterns might emerge in mathematics and science course taking for students based on when they took Algebra 1. The findings indicated that students in this cohort who took Algebra 1 in eighth grade were more likely to complete the highest level mathematics courses available to them than those who took Algebra 1 in seventh grade, but they also took, on average, fewer total mathematics and science courses. For all students taking middle school Algebra 1, there were sharp declines in students accessing honors-level mathematics coursework as they advanced through the mathematics sequence. / Doctor of Education / The purpose of this study is to assess the impact of a school division policy on early algebra on students' course taking patterns in high school.

The objective of this study is to examine the impact of students accessing Algebra 1 in the 8th grade on their science course-taking patterns in high school in a large district in the Mid Atlantic of the United States. This is an important question because many studies have shown that Algebra 1 is a "gatekeeper" course (Adelman, 1999, 2006) but there has not been much research around the impact of who has taken Algebra 1 by 8th grade and what science courses they took as a result of having access to that particular course (Xin Ma, 2009). The data will be supplied by the school district of the last two cohorts of graduating seniors who were in the district from the seventh grade on, so the analysis can be conducted on those who were subject to the same opportunities and policies. The demographic information that will be requested are: Free/Reduced Meal students (FRMS) as a proxy for socio-economic status (SES), gender, race, English as a Second Language (ESOL) level, Special Education (SPED), what grade the students took Algebra, and the science classes they took while they were in high school. The research questions will be analyzed using JMP, a statistics program supplied by Virginia Tech to see if there are any significant differences in which groups of students took Algebra 1 by 8th grade and what kinds of science courses they took. The major findings were that more White and Asian students, and higher SES students accessed Algebra 1 by 8th grade and were enrolled in more rigorous science classes in their high school career than their Black, Hispanic, low SES, Special Education or English Language peers. The results of this study could inform large school districts about the impact of Algebra 1 by 8th grade on students' science course-taking patterns and promote conversations about their policies they create about access to critical courses. / Doctor of Education / The objective of this study is to examine the impact of students accessing Algebra 1 in the 8th grade on their science course-taking patterns in high school in a large district in the Mid Atlantic of the United States.

The research could be used by school leaders as context for when they examine the participation of students in their upper level science classes. It could also be used by school counselors to better communicate with families about the importance of mathematics preparation and readiness and the impact of those on other college track courses.
