An understanding of biological variation is important for understanding ecological interactions, ecosystem function, and species' response to environmental change. Biological variation is essential to species survival because natural selection acts upon the phenotypic variation within a population: the more varied the population's genetic…

We used problem-based or experiential learning in our undergraduate Health Policy course to examine food deserts via a health impact assessment (HIA) assignment. An HIA evaluates potential effects on population health before a policy/program is implemented, to improve health and reduce adverse outcomes. We investigated if the HIA assignment…

The utility of Just-In-Time-Teaching (JITT) is compared across course topics and groups of students not receiving JITT exercises in class. JITT feedback incorporated various active learning exercises based on students' performance on online homework problems from Sapling Learning.

This project studied the effect of individualized, voluntary learning contracts for 18 students who performed poorly in the first part of the semester. Contracts were hypothesized to increase commitment and motivation, and lead to changes in behaviors and course performance. Self-reported prioritization and learning-related behaviors (completion…

Many factors affect students selecting a university to attend and almost as many factors that can present challenges once they enroll and begin attending classes. Once they start taking courses, the next challenge is completing them, and this can be particularly taxing for online students. In the case of online universities, quality assessment…
