WWC Summary of Evidence for this Intervention
Saxon Algebra II
Saxon Math is a core curriculum for students in grades K–12 that uses an incremental approach to instruction and assessment. This approach limits the amount of new math content delivered to students each day and allows time for daily practice. New concepts are introduced gradually and integrated with previously introduced content so that concepts are developed, reviewed, and practiced over time rather than being taught during discrete periods of time, such as in chapters or units.
As of May 2016, no studies of Saxon Algebra II were found that fell within the
scope of the Secondary Mathematics review protocol and met WWC evidence standards.
Therefore, the WWC is unable to draw any research based conclusions
about the effectiveness or ineffectiveness of Saxon Algebra II to improve outcomes in this area.

The number of studies that met WWC design standards and provide evidence of effectiveness. Selecting an item below will display all studies that met WWC design studies in the domain. Selecting a study citation will take you to more information on that study and its findings.
For more, please see the WWC Glossary entry for study rating.
Grades of the students examined in the studies that met WWC design standards, which may not reflect the full range of grades for which the intervention may be used.
The number of students included in the studies that met WWC design standards.
An indicator of the size of the effect from using the intervention. It is the expected change in percentile rank for an average comparison group student if the student had received the intervention, ranging from -50 to +50. At the domain level, the improvement index is only shown if the effectiveness rating is positive, potentially positive, potentially negative, or negative; dashes are displayed for mixed or no discernible effects. At the study level, the improvement index is only shown if the findings are characterized as statistically significant or substantively important (greater than +10 or less than -10); dashes are displayed for an indeterminate effect.

The indicator represents the highest level of similarity found between your students and each of the high-quality studies of the intervention. Three filled in ovals indicates that at least one study that met standards was conducted on students very similar to yours. Clicking on the indicator for a study will provide information on the similarity for each of the characteristics you selected.
