Effects of SI-PASS on a high-risk course – A randomized controlled trial

Background

SI-PASS is a structured academic support program employing successful later-year students to facilitate peer-learning sessions attached to high-risk courses, specifically here statistics for psychology at ULiège. The research translates as: How much does this method improve academic performance and impact socio-affective perceptions in first-year students?

Aims

This study compares academic performance and socio-affective variables of first-year students in the experimental condition and the control condition.

Sample

Participants were 245 freshmen for the experimental trial, and 985 for the quasi-experimental trial.

Methods

Participants were assigned to either participate to the SI-PASS scheme or not during the first semester following a randomized controlled trial with stratified random assignment method. Then, the whole cohort enlisted for the course was analyzed to validate supplementary hypotheses.

Results

The first step of the study reveals no difference between both groups on academic performance, unless the level of attendance is considered; nor does it identify any significant impact on socio-affective variables. The second step consisted in the comparison of the experimental group and the group of students who chose not to volunteer for SI-PASS and resulted in significant improvement in academic performance in favor of SI-PASS.

Conclusions

This delivered significant results in favor of the program but only when attendance is considered, thus offering empirical evidence that a genuine experimental design is likely to mitigate the effects found in a tradition of quasi-experimental designs. These results are valuable for the SI-PASS community, where randomized trials are still scarce, and for higher education institutions seeking evidence-based assistance.
