Tietz, Paul I. – Natural Sciences Education, 2019
Hydraulic fracturing is a major process for oil and natural gas production in the United States, and sand mines in Western Wisconsin provide highly desirable sand for the fracturing industry. After being mined, sand is wet-sieved to isolate economical-size fractions. Polyacrylamide is used as a flocculant to settle out the fine particles,…

Petitt, Destini N.; Forbes, Cory T. – Natural Sciences Education, 2019
Growing human populations place increasing demands on our planet, resulting in an array of challenges with both scientific and non-scientific dimensions. These challenges are collectively known as socio-scientific issues (SSIs). It is essential to understand how students learn to use values to reason about SSIs, particularly when dealing with…

Dick, Nathaniel – Natural Sciences Education, 2019
The sunflower head moth is considered the most damaging pest to sunflowers in Kansas. This small cigar shaped moth can severely impact the yield of commercial sunflowers. A sunflower plant infested with sunflower head moth larvae can also become very susceptible to Rhizopus fungi which causes head rot and can significantly add to the economical…

Sindelar, Meghan; Mamo, Martha; Wingeyer, Ana – Natural Sciences Education, 2018
Students who have completed the Soil Nutrient Relationships course at the University of Nebraska-Lincoln often contact instructors once they have begun full-time work, seeking reminders of specific concepts. These students either did not take or keep detailed notes during the course. To assist students, instructors have developed a portfolio…

Smith, Kayla – Natural Sciences Education, 2017
The world population is expected to reach 9.2 billion by the year 2050. Farmers are faced with the daily challenge of how to feed these people while availability of land and water is dwindling. The growth rates of global agricultural production and crop yields have slowed in the last couple of years, raising fears that the world may not be able to…

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…

Zerger, Sarah – Natural Sciences Education, 2017
Sugarcane aphids are becoming a more prevalent pest in sorghum in the United States, especially in the south and are making their way north. There are many management practices that can be used on sugarcane aphids, the most important being scouting and maintaining populations. The most common mistake once a pest has been found is to immediately…

Bigelow, Cale A.; Kaminski, John E., III – Natural Sciences Education, 2016
Most undergraduate students arrive on campus fluent in electronic communication methods and social media (SM). This cultural or communication shift presents both opportunities and challenges in pedagogy. Social media allows users to share and network with geographically diverse individuals and has the potential for engaging students both inside…

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…
