Modeling Gross Primary Production Of Midwest Maize And Soybean Croplands With Satellite And Gridded Weather Data, Gunnar Malek-Madani
Modeling Gross Primary Production Of Midwest Maize And Soybean Croplands With Satellite And Gridded Weather Data, Gunnar Malek-Madani
Department of Geography: Dissertations, Theses, and Student Research
The gross primary production (GPP) metric is useful in determining trends in the terrestrial carbon cycle. Models that determine GPP utilizing the light use efficiency (LUE) approach in conjunction with biophysical parameters that account for local weather conditions and crop specific factors are beneficial in that they combine the accuracy of the biophysical model with the versatility of the LUE model. One such model developed using in situ data was adapted to operate with remote sensing derived leaf area index (LAI) data and gridded weather datasets. The model, known as the Light Use Efficiency GPP Model (EGM), uses a four …
Modeling Microorganism Transmission With Madagascar Hissing Cockroaches: An Inquiry Activity, Hillary Guzik, Kessler Mccoy-Simandle
Modeling Microorganism Transmission With Madagascar Hissing Cockroaches: An Inquiry Activity, Hillary Guzik, Kessler Mccoy-Simandle
Department of Entomology: Faculty Publications
Students will test Madagascar hissing cockroach’s capacity as a vector for transmission of microorganisms. By comparing a cockroach exposed to human contact (handled by students) and a cockroach with limited exposure (not handled), students can assess the ability of cockroaches to transmit microorganisms from one location (hands) to another (agar plate where the microorganism will be grown). This will allow students to determine if the Madagascar hissing cockroach, the classroom pet, is a potential vector for microorganisms. Students then will be able to question and relate the concept of insects and objects as vectors for common pathogen transfer.

In response to recent educational imperatives in the United States, modeling and systems thinking have been identified as being critical for science learning. In this paper, we investigate models in the classroom from two important perspectives: (1) from the teacher perspective to understand how teachers perceive models and use models in the classroom and (2) from the students perspective to understand how student use model-based reasoning to represent their understanding in a classroom setting. Qualitative data collected from 19 teachers who attended a professional development workshop in the northeastern United States indicate that while teachers see the value in teaching …
