How Principal Characteristics Including Experience, Leadership Style, Philosophy, and Education Influence Science Achievement
… and determine how the characteristics influenced science achievement. The context of this inquiry was a school system in the southern United States where 55% of elementary students scored below grade level on the end-of-grade science assessment compared to the state average of 36%. I conducted a …

Science as a Second Language: Analysis of Emergent Bilingual Performance and the Impact of English Language Proficiency and First Language Characteristics on the Colorado Measures of Academic Success for Science
… even more important than ever. The language of science has been compared to a second language in that it uses specific discourse patterns, semantic rules, and a very specific vocabulary. There is a need for educators to better understand how language impacts academic achievement, specifically …

Modeling of N2O emission from unmanaged terrestrial ecosystem soils
… I employ a land surface model, the Integrated Science Assessment Model (ISAM), to model the global N2O emissions from terrestrial ecosystem soils. The model is calibrated and evaluated with field measurements of N2O from different sites with different biome types, climate conditions, and soil …

Modeling the combined environmental effects on net land carbon flux in the present and future scenarios
… by using a global land surface model, Integrated Science Assessment Model (ISAM). The model is driven by historical observation data and future projection data from Scenario Model Intercomparison Project (ScenarioMIP) of Coupled Models Intercomparison Project Phase 6 (CMIP6). Two combinations of …

Quantifying biophysical and biogeochemical influence on northern high latitudes greenhouse gases dynamics
… calibrated a land surface model, the Integrated Science Assessment Model (ISAM), to explore how the physical and chemical interactions within the atmosphere-land-soil continuum determined the production, transport and flux of GHGs from site to regional and global scales. I focused on the impacts …

Comparison of the Item Response Theory with Covariates Model and Explanatory Cognitive Diagnostic Model for Detecting and Explaining Differential Item Functioning
In psychometrics, a concern is that the assessment is fair for all students who take it. The fairness of an assessment can be evaluated in several ways, including the examination of differential item functioning (DIF). An item exhibits DIF if a subgroup has a lower probability of answering an item …
