How Students Communicate Knowledge: Written Versus Drawn Responses To Formative Assessment Questions In An Introductory Undergraduate Marine Science Course, Christina Siddons
How Students Communicate Knowledge: Written Versus Drawn Responses To Formative Assessment Questions In An Introductory Undergraduate Marine Science Course, Christina Siddons
Electronic Theses and Dissertations
Undergraduate science education suffers from a lack of concrete instructional strategies that address real-world postgraduate skills such as visual literacy and science communication. Research within marine science education especially lags behind other, more well-researched fields such as physics or mathematics education, both of which have extensive literature addressing specific instructional strategies that instructors can implement in the classroom. Undergraduate marine science programs overlap with content areas from chemistry, physics, and biology, and provide a rich opportunity for examining how to include more authentic educational experiences in an undergraduate classroom. However, the types of assessments that are typically employed tend to …
Deciphering Climate-Driven Changes In Planktonic Diatom Communities In Lake Superior, Amy Kireta
Deciphering Climate-Driven Changes In Planktonic Diatom Communities In Lake Superior, Amy Kireta
Electronic Theses and Dissertations
Climate change is affecting lake systems throughout the world, including Lake Superior, the world’s largest lake by surface area. Climate-driven physical changes in Lake Superior are well documented, but there is still substantial uncertainty of how recent biological changes are related to climate change. This research addresses these uncertainties using a variety of approaches to understand the effects of modern climate-driven changes on Lake Superior diatom communities. First, I developed models for environmental variables related to diatom abundance using 10 years of summer monitoring data. Second, I investigated changes in fossilized diatom relative abundances before, during, and after the Medieval …
