Student attendance in class, and participation while in class, are predictors of student performance. Last year, we reported on a new measure combining class attendance and attentiveness while in class and used this participation score as a predictor of student performance on the final exam in the class. This year, we follow up by analyzing data for four classes in the Fall semester of 2019. In each class, and for the four classes combined, we found a statistically significant relationship between participation and score on the final exam.
