### High School Algebra I for Middle Grade Students studies

### Background on Student Assessments

CPS students historically have taken their first year of algebra (Algebra I) in the ninth grade. As discussed earlier, the CMSI sought to increase the number of students who take a high school level algebra course in the middle grades. High School Algebra I for Middle Grade Students refers to the district-approved and managed Algebra I course taught to students in middle grades (usually eighth grade). These courses are intended to offer the same content as High School Algebra and to prepare students for the next level of high school math, usually Geometry. At the successful completion of this course, students take the citywide, Algebra Exit Exam
^{cite}.
Exam results are one factor (in addition to grades) in determining placement in higher-level mathematics courses in high school.

A series of analyses were conducted on the high school outcomes of students who took the Algebra Exit Exam. Students were included in this study if they were in Chicago Public Schools in both 8^{th} grade in 2006-07 and in 9^{th} grade in 2007-08. A file of these students was created by combining master files (with enrollment and demographic data), the Algebra Exit Exam file (with test outcomes and teacher data), 9^{th} grade EXPLORE ^{cite}.
scores, 7^{th} grade ISAT scores, and 9^{th} grade course enrollments and grades. For the purposes of this study, the researchers simplified the ninth grade mathematics course types to five options, as shown in Table 1.

Using the course files the researchers also calculated a mathematics GPA for each semester
^{cite}.

Researchers computed:

Researchers also examined each of these variables by the student's participation in 8th grade Algebra as well as by their performance on the High School Algebra I for Middle Grade Students assessment (Exit Exam) and applied appropriate statistical tests (e.g., t-tests and chi-squares) to test for statistical differences between groups.

- Means and frequencies on demographic information (Free/Reduced-Price Lunch (FRPL), Limited English Proficiency, Individualized Educational Program, type of school, ethnicity, and gender),
- Teacher characteristics (certifications, years of teaching and highest educational attainment),
- Ninth grade outcomes (enrollment and grades in math courses, EXPLORE scores, and course absences), and
- Prior academic achievement (7
^{th}grade ISAT scores).Finally, the researchers built models predicting the ninth-grade outcomes (mathematics course passing rates, course grades and EXPLORE scale scores) using participation in the High School Algebra I for Middle Grade Students assessment. These models compare students who took the Algebra Exit Exam to those who did not take the test and incorporated common statistical controls as described in the bullet points above.

The researchers modeled the impact of Proficiency alone on the ninth grade outcomes. In other words, they examined the difference between Proficient (defined as those that met the passing cutoff score on Algebra Exit Exam) and non-Proficient students, excluding those who did not take the assessment. To these models the following teacher qualification controls were added:

- Type 9 Certification (type9),
- Number of years teaching (yrs),
- Master's degree (masters)

The Type 9 certification in Illinois refers to teachers who are certified to teach high school level mathematics, as opposed to the Type 3 certification, which permits teaching elementary school level mathematics in Illinois. If a teacher had both types of certifications, the Type 9 was counted.

After considering the outcomes of these models, the researchers examined whether interaction effects should be included and found several significant effects. The relationship between participation and EXPLORE scores, for example, was more extreme for FRPL than for non-FRPL students (high versus low income students) and thus the researchers incorporated these interaction effects into the full statistical models.

From these studies the following findings emerged:

### Participation Effects

- Algebra I for Middle Grade participating students were statistically more likely to pass
their 9
^{th}grade math courses, get higher grades in ninth grade math and have higher EXPLORE mathematics scores than non-participating students- This effect was even larger among
__lower achieving__students (as measured by the 7^{th}grade ISAT).

- This effect was even larger among

### Proficiency Effects

- Proficient students were statistically more likely to get higher grades in ninth grade math
and have higher EXPLORE mathematics scores than non-proficient students.
- This effect was even larger for
__lower achieving__students (as measured by the 7^{th}grade ISAT).

- This effect was even larger for

To summarize, students who took the High School Algebra I for Middle Grade Students course had higher grades in ninth grade mathematics and performed better on the EXPLORE mathematics assessment than their similar peers who had not taken algebra in elementary school. The improvements were greatest for those students who were lower-performing as measured by their 7^{th} grade ISAT scores, prior to enrolling in Algebra in the 8^{th} grade.
