Evaluating the Impact of Supplemental Instruction Leader Engagement on Student Success

Lindsey G. Knight & Ariana Mitchell for the School of Data Science and Analytics

    • Performance data from the Kennesaw State University Supplemental Instruction program was collected for the Fall 2023 semester.
    • Linear and logistic regression were performed to investigate the role of SI Leader  engagement (through observations and professional development attendance) on student performance (measured by mean grade and DFW rates).
    • SI leader engagements were able to accurately predict the probability of high overall DFW rates (>25%) and passing student grades (>2.0)
    • The Supplemental Instruction (SI) program is a peer-led academic support program that helps improve understanding for a course’s material in a course that has a historically high drop, withdraw, and fail (DWF) rate.
    • SI Leaders are required to complete a minimum of three observations and three professional developments or pedagogy trainings per semester. Pedagogy training focuses on enhancing a leader’s facilitation strategies and collaborative learning techniques.
    • The Kennesaw State University SI program is accredited by the International Center for Supplemental Instruction (ICSI) which helps secure additional funding as our program grows.
    • Success of the program is measured through attendance for each session and the final grades and DWF rates of students who both attended and did not attend SI sessions.
    • The goal of this project is to evaluate the efficacy of KSU's SI Program and determine if SI leader required trainings significantly contribute to student success.
    • We also explored how accurately an SI leader's engagement could predict their students' success
    • Data was collected for SI Leader observations, professional developments, session attendance, and student performance for the fall 2023 semester.
    • Data was filtered so that only SI leaders who returned for spring 2024 were included (n=38). This was done so trends could more easily be identified across semesters in future analysis.
    • Linear regression analysis was used to explore SI Leader observations and professional development (PD) attendance in relation to student performance (measured by mean GPA), and DFW rates for all students (overall) and for students who attended sessions (SI DFW)
    • For predictive analysis, datasets were split into approximately 80% training and 20% testing, and our linear regression models were used to predict passing scores (GPA>2) and high DFW rates (DFW>25%).

  • Results

    Correlation:

    There was statistically significant correlation between mean grade and number of times observed, mean grade and number of observations performed, overall DFW rate and number of observations performed, overall DFW rate and PDs attended, and SI DFW rate and PDs attended.

    Regression:

    • An increase of one observation received is associated with a 0.18 point decrease in mean student grade.
    • An increase of one observation performed is associated with a 0.13 point increase in mean student grade.
    • An increase of one PD attended is associated with a 3.85% decrease in SI DFW rates.
    • An increase of one observation performed is associated with a 1.53% decrease in overall DFW rates.
    • An increase of one PD attended is associated with a 4.25% decrease in overall DFW rates.

    Discussion

    • Correlations between SI leader engagements and student success metrics are relatively weak but are significantly different from zero. This indicates that engagement has some level of influence on student success.
    • The number of times observed appears to have a negative impact on mean student grade which indicates that receiving too may observations may be counterintuitive.
    • The models predicting passing grades and overall DFW rates exhibit high predictive accuracy (87.5%).
    • The model predicting SI DFW rates indicates that PDs do not accurately predict high DFW rates.
    • Higher SI leader engagement is associated with overall increased student success metrics.

Describing the Role of Supplemental Instruction Leaders as Agents of Academic Success

Lindsey G. Knight & Ariana Mitchell for the School of Data Science and Analytics

    • Performance data from the Kennesaw State University Supplemental Instruction program was collected for the fall 2024 semester.
    • Student's t-tests and linear regression were used to determine if SI leaders were more impactful in improving student success or class enrollment retention. The impact of SI leader engagement on course DFW rates was compared between the fall 2023 and fall 2024 semesters to identify potential trends.
    • The Supplemental Instruction (SI) program is a peer-led academic support program that helps improve understanding for a course’s material in a course that has a historicallyhighD, fail, and withdraw (DFW) rate.
    • SI Leaders are required to complete a minimum of three observations and three professional developments or pedagogy trainings (PDs) per semester. Pedagogy training focuses on enhancing a leader’s facilitation strategies and collaborative learning techniques.
    • Success of the program is measured through attendance for each session and the final grades and DWF rates of students who both attended and did not attend SI sessions.
    • The goal of this project is to evaluate the efficacy of KSU's SI Program and determine if SI session have more of an impact on class retention or student success.
    • We also explored how accurately an SI leader's engagement could predict their students' success.
    • Data was collected for SI Leader observations, professional developments, and student performance for the fall 2024 semester.
    • A two-tailed t-test was performed in R to determine if there was a significant difference between DF and W rates for students who attended SI sessions.
    • Correlation analysis performed in SAS was used to determine if there was a significant relationship present between PDs completed, times observed, and DF/W rates. Regression analysis was performed in R to predict DF/W rates for students who attend SI sessions using the PDs completed.
    • Regression from the fall 2024 semester was compared to the fall 2023 semester to identify potential trends in the impact of SI leader engagement on student DFW rates.
    • This analysis included 107 unique SI leaders.

  • Results

    • The mean difference between DF Rates for SI and Non-SI-attending students is 6.16%. The p-value of <0.001 indicates that students who attend SI sessions have a significantly lower DF rate that students who do not attend sessions.
    • The mean difference betweenW Rates for SI and Non-SI-attending students is 9.37%. The p-value of <0.001 indicates that students who attend SI sessions have a significantly lowerW rate that students who do not attend sessions.
    • The number of times an SI leader was observed does not correlate with their class's DF, W, or DFW rates.
    • The number ofPD trainings a leader completed has a weak positive correlation with DF rate and a weak negative correlation with W rate.
    • The number ofPD trainings completed is a significant predictor of both DF and W rates.
    • For every additional PD completed, the DF rate will increase by 1.94% and the W rate will decrease by 1.91%. Number of PDs completed is a statistically significant predictor at the 0.10 significance level.
    • While PDs completed was a significant predictor of DFW rates for the fall 2023 semester, it is not a significant predictor of DFW rates for the fall 2024 semester.

    Discussion

    • The correlation between PDs completed and W rates is weak but significantly different from zero and indicates SI leaders have a positive impact on class retention.
    • The DF rate increased per additional PD while the W rate decreased per additional PD which indicates PDs are better suited for improving class retention as opposed to student success within the class.
    • The models predicting SI DFW Rates are more significant in fall 2023 than fall 2024, indicating that PDs are not presently as effective.
    • This analysis indicates a need to evaluate the current professional development trainings offered in order to determine how to better tailor SI leader trainings toward improving student success in the classroom.
