The Iinfluence of social style in evaluating academic presentations ofengineering projects

Héctor Ortiz Valencia, Àgueda García Carrillo, María Margarita González Benítez


An individual’s social style is determined by behavioral patterns in the interactions with their peers. Some
studies suggest that social style may influence the way in which an individual’s performance is evaluated. We
studied the effects that speakers’ and evaluators’ social styles have on the marks given for end-of-term
presentations in a project engineering master’s course. The participants completed a self-evaluation exercise
that classified their social styles into one of four categories: Driver, expressive, analytical, or amiable. Students
individually rated the content and appearance of their classmates’ presentations. A statistical analysis of these
scores revealed that the speaker’s social style had a significant effect on the marks received for content and
appearance. The evaluator’s social style also demonstrated a statistically significant effect on the marks given
for appearance, though not for content. Students with expressive social style received the highest scores, while
the analytical style received the lowest scores. These results reiterate the necessity to train students as
evaluators in order to reduce bias when evaluating their classmates and co-workers during their academic and
professional careers.
