In this work we describe the placement
testing and student intake process at a large, land-grant university and show
that long-standing general assessment exams administered during secondary schooling
are not accurate predictors of success in university level mathematics courses.
We then present results indicating that a placement exam administered during
arrival as a first-year student provides a strong indicator of potential for
student success in first-semester calculus.
Given that alcohol use is highly prevalent at US colleges, we explored
factors related to problem drinking behaviors (PDB; binge drinking, driving
after drinking, sexual intercourse after drinking)
among 4098 Black and White students from two- and four-year colleges who
completed an online survey. We found an interaction between race and sex such
that, among Whites, females had less PDB than males (B = 0.09, CI: 0.05; 0.40,
p = 0.01). An interaction between race and school type also existed, such
that White students from four-year schools had greater PDB (B = 0.11, CI: 0.20;
0.54, p < 0.001). An interaction between race and stress suggested that
Black students were more negatively affected by stress in terms of PBD (B = 0.12,
CI: 0.01; 0.07, p = 0.01).
