Lindsay, Andrew – Natural Sciences Education, 2017
The application of charcoal to soils to increase carbon stocks has been of great interest recently. To gain a better understanding of the long-term effects of charcoal presence in soils, historic charcoal production sites at Catoctin Mountain Park, Maryland were studied for organic carbon content and compared to nearby unaffected soils. Soil…

Michels, Kristin K.; Michels, Zachary D.; Hotchkiss, Sara C. – Natural Sciences Education, 2016
Although spatial reasoning and penetrative thinking skills are essential for many disciplines, these concepts are difficult for students to comprehend. In microscopy, traditional educational materials (i.e., photographs) are static. Conversely, video-based training methods convey dimensionality. We implemented a real-time digital video imaging…

Monroe, Martha C.; Plate, Richard R.; Colley, Lara – Natural Sciences Education, 2015
This research study investigated the learning outcomes of a brief systems thinking intervention at the undergraduate level. A pre/post experimental design (n = 50) was used to address two primary questions: (1) Can a brief introduction to systems thinking improve students' understanding of systems thinking? and (2) Which teaching method (of…

Greenway, Gina A.; Makus, Larry D. – Natural Sciences Education, 2014
Online course offerings have been growing at a rapid pace in post-secondary education. An ordered probit model is estimated to analyze the effects of online vs. face-to-face course format in achieving specific letter grades. An upper-division agricultural economics course taught over 9 years using both formats is used for the analysis. For a…
