With condensed courses, students focus on a smaller number of courses during seven- to ten-week terms (Gullatt, 2006; Zepeda & Mayers, 2006).

By design, randomized experiments (XPs) rule out bias from confounded selection of participants into conditions. Quasi-experiments (QEs) are often considered second-best because they do not share this benefit. However, when results from XPs are used to generalize causal impacts, the benefit from unconfounded selection into conditions may be offset…

Practice ACT scores were used as a covariate to control for individual differences in student scores. Participants consisted of 264 students from one graduating class at a large high school in…
