Figure 1
Two graphs depict the impact of SI support on class GPA and grade distribution over semesters. Panel A shows a vertical bar graph comparing the GPA difference between classes with and without SI support across different classifications of classes. The x-axis represents the classification of classes, including AI with SI, Core STEM 100, First Majors, and Advanced. The y-axis represents the GPA difference. The bars indicate that Core STEM 100 and Advanced classes show a significant GPA difference with SI support, while AI with SI shows a minimal difference. Panel B shows a stacked bar graph representing the percentage grade distribution in a key 100-level class that was flipped specifically to make use of SI support over different semesters. The x-axis represents the semesters, including Spring 2021, Fall 2021, Spring 2022, and Fall 2022. The y-axis represents the percentage. The stacked bars are color-coded to represent different grades: E, D, C, B, and A. Track 1, the ARC and student Supplementary Instructors (SIs). Source: The authors
