Student Evaluation of Teaching: The Inequity of Faculty Scores in Online versus Face-to-Face Courses

Researchers have conducted a multitude of studies over the last century on Student Evaluations of Teaching (SET); however, very few have been conducted in the new digital age (Loveland, 2007). More work is in progress as researchers try to define the differences in student responses and thoughts about the online teaching environment. The unfortunate side of this can be the administrative decision to use a one-size-fits-all mentality when many authors including Dziuban and Moskal (2011) have outlined several research-based alternatives for evaluation of online instructional effectiveness. SETs are important to faculty because they often are the determining factor in merit pay and tenure/promotion. Faculty use SETs to guide decision-making about their curriculum and instructional strategies used to deliver the course (Sheehan & DuPrey, 1999). The power of the SET is recognized as a driving force in academia. What are often not discussed are the differences between SET for face-to-face courses versus SET for online courses

How Gradient Affects the Foraging Decisions of Leaf Cutting Ants at the Food Source

The eusocial insects have long held the fascination of scientists for their co-operative behaviour, which can range from a small group of workers, to millions strong colonies, such as those found in the leaf cutting ant, Atta cephalotes. Though decades of research have allowed us some insight into their organisation and methods, there are many things that have gone unexplained. One of these is the mystery of why Atta consistently takes leaf loads back to the nest that are significantly smaller than would be optimal, when they should in theory optimise leaf transport rate. While compelling evidence has been presented to suggest that it is at least in part to do with how the leaves are processed inside the nest, here I present evidence to suggest that gradient is another key factor. This is a factor which has been explored only very cursorily up until now in leaf cutting ants, with experiments investigating it being extremely limited in scope, suffer from potential methodological errors or deal with grass cutting ants, which share many traits with leaf cutting ants, but have adapted to face different challenges. Upon a thorough examination of the effects of gradient, it was discovered that A. cephalotes favour a cautious, but more reliable method of transport. At almost every point, their behaviour shows the importance of maintaining grip on steep and vertical gradients to the point where it is prioritised over everything else, including speed and load size. While it may seem paradoxical to suggest that smaller loads, carried slower might result in a higher overall rate of leaf collection, a fast, but reckless approach might result in a high proportion of unsuccessful foraging trips, each of which costs energy and time. As a result, by increasing their success, rather than speed, they minimise wasted effort, loss of workers and potentially, have a higher rate of leaf collection over time. This aspect of leaf cutting ant behaviour shows that leaf cutting ants can change their priorities at the feeding site to best maximise transport success at an individual level, which demonstrates previously unappreciated plasticity and a new lens through which to view future investigations into ant foraging behaviour

Marrying Community Benefits and Development Practice

After exhaustive study and evaluation, D4 has concluded that in order for community benefits to be effective in Michigan, they need to be embedded early in the development process. But how to effect these policies without driving away private investment remains a key question. Building from previous preliminary research, D4's project will describe recommendations for how to insert community benefit provisions into standard development processes, including RFPs, TIFs, and incentive overlay districts
