Thinking Aloud In The Science Classroom: Can A Literacy Strategy Increase Student Learning In Science?, Lindsey Joan Mockel Aug 2013

Thinking Aloud In The Science Classroom: Can A Literacy Strategy Increase Student Learning In Science?, Lindsey Joan Mockel

Dissertations and Theses

This research study investigated the effect of using the think aloud protocol while reading informational text on students' ability to learn from text in a secondary science classroom. The participants in this study were high school students (n=47) in three classes of a mixed-grade Integrated Biology, Chemistry, and Physics course. The study tracked student achievement during a four-week curriculum unit on the theory of evolution and evidence for biological evolution. All students received instruction on using the think aloud protocol, and all students practiced the think aloud protocol when reading short articles related to scientific evidence for evolution. The researcher …


Air-Quality And Climatic Consequences Of Bioenergy Crop Cultivation, William Christian Porter Jun 2013

Air-Quality And Climatic Consequences Of Bioenergy Crop Cultivation, William Christian Porter

Dissertations and Theses

Bioenergy is expected to play an increasingly significant role in the global energy budget. In addition to the use of liquid energy forms such as ethanol and biodiesel, electricity generation using processed energy crops as a partial or full coal alternative is expected to increase, requiring large-scale conversions of land for the cultivation of bioenergy feedstocks such as cane, grasses, or short rotation coppice. With land-use change identified as a major contributor to changes in the emission of biogenic volatile organic compounds (BVOCs), many of which are known contributors to the pollutants ozone (O3) and fine particulate matter …


Effects Of Hru Size On Prms Performance In 30 Western U.S. Basins, Madeline Olena Steele Apr 2013

Effects Of Hru Size On Prms Performance In 30 Western U.S. Basins, Madeline Olena Steele

Dissertations and Theses

Semi-distributed hydrological models are often used for streamflow forecasting, hydrological climate change impact assessments, and other applications. In such models, basins are broken up into hydrologic response units (HRUs), which are assumed to have a relatively homogenous response to precipitation. HRUs are delineated in a variety of ways, and the procedure used may impact model performance. HRU delineation procedures have been researched, but it is still not clear how important these subdivision schemes are or which delineation methods are most effective. To start addressing this knowledge gap, this project investigated whether or not HRU size has a significant effect on …
