Many universities and colleges recognize the critical need for undergraduate engagement in research and participation in professional world experiences to cultivate aptitudes required in the 21^st century. Using a triangulation inquiry methodology, this empirical study contributes to the research on undergraduate research mentorship pedagogy by assessing its merits operationalized across multiple disciplines at a …

Teacher And School Characteristics: Predictors Of Student Achievement In Georgia Public Schools, Alisande F. Mayer, Ellen W. Wiley, Larry P. Wiley, Dianne C. Dees, Simmie A. Raiford

Georgia Educational Researcher

Student achievement of fifth-grade students in 106 Georgia public schools in CRCT reading and mathematics was examined as a function of five characteristics of teachers and schools. The five independent variables used as predictors of CRCT scores were Title I status, teachers’ education level, teachers’ average years of experience, class size, and computer to student ratio. Designation as a Title I school was the strongest predictor of student achievement. When compared to non-Title I schools, Title I school status resulted in a higher percentage of students meeting CRCT standards in both reading and math and a lower percentage of students …

Is Cultural Responsiveness Part Of Effective Teaching?: Preservice Teacher Perspectives, Yasar Bodur

Georgia Educational Researcher

The purpose of this study was to investigate the extent to which preservice elementary teachers integrated culturally responsive pedagogy into their perspectives on effective teaching and being an effective teacher and if these perspectives changed over time. Data were collected from 53 preservice teachers in the form of a perspective paper written in two consecutive semesters at the end of field experience courses. Data were analyzed both quantitatively and qualitatively. Findings indicated that preservice teacher integrated issues of cultural and linguistic diversity into their perspectives minimally. Linguistic diversity was more integrated than cultural diversity. Their perspectives included less integration of …

A Hopeful Pedagogy To Critical Thinking, Mark C. Nicholas, Miriam Raider-Roth

International Journal for the Scholarship of Teaching & Learning

Elements of what we are calling a “hopeful pedagogy” emerged when faculty reflected on the question - Do you think your current approach to develop CT in students is successful? Faculty across disciplines and institutions used the word “hope” to characterize the outcome of their efforts. While attempting to disentangle the “hopeful pedagogy”, we found answers in (a) how faculty defined CT in disciplinary and non-disciplinary contexts; (b) a misalignment between faculty and institutional approaches to CT; (c) a disconnect between faculty and their own approaches to CT, and (d) logistical and curricular issues within general education programs that placed …

Learning Sustainability Leadership: An Action Research Study Of A Graduate Leadership Course, Heather L. Burns

International Journal for the Scholarship of Teaching & Learning

This study used action research methodology to examine the development of sustainability leadership in a graduate leadership course. The research investigated the impact of this leadership course, which was designed using transformative learning theory with attention to integrating thematic content, multiple and non-dominant perspectives, a participatory process, and a contextual place-based approach. Grounded theory was used to explore if and how students’ understanding of sustainability leadership changed, and the pedagogical strategies that were most influential to their learning. Results revealed that students came to understand sustainability leadership as: the facilitation of a shared process, a process of emergence, and a …

Becoming A Scientist: Using First-Year Undergraduate Science Courses To Promote Identification With Science Disciplines, Chloe Ruff, Brett D. Jones

International Journal for the Scholarship of Teaching & Learning

In this qualitative study, we examined how two professors (a physicist and biochemist) of first year college students perceived their students’ development of identification in biochemistry or physics and how they actively supported this development. The professors described students who entered college with different levels of domain identification and different expectations for their college science experience depending upon whether they were in a biochemistry or physics major. Although neither professor was familiar with research related to the concept of domain identification, their beliefs about their students’ identification and academic support strategies generally aligned with the Osborne and Jones (2011) model …

Spatiotemporal Interpolation Methods For The Application Of Estimating Population Exposure To Fine Particulate Matter In The Contiguous U.S. And A Real-Time Web Application, Lixin Li, Xiaolu Zhou, Marc Kalo, Reinhard E. Piltner

Mathematical Sciences: Faculty Publications

Appropriate spatiotemporal interpolation is critical to the assessment of relationships between environmental exposures and health outcomes. A powerful assessment of human exposure to environmental agents would incorporate spatial and temporal dimensions simultaneously. This paper compares shape function (SF)-based and inverse distance weighting (IDW)-based spatiotemporal interpolation methods on a data set of PM_2.5 data in the contiguous U.S. Particle pollution, also known as particulate matter (PM), is composed of microscopic solids or liquid droplets that are so small that they can get deep into the lungs and cause serious health problems. PM_2.5 refers to particles with a mean aerodynamic …

Example Of An Order 16 Non Symplectic Action On A K3 Surface, Jimmy J. Dillies

Mathematical Sciences: Faculty Publications

We exhibit an example of a K3 surface of Picard rank 14 with a non-symplectic automorphism of order 16 which fixes a rational curve and 10 isolated points. This settles the existence problem for the last case of Al Tabbaa, Sarti and Taki's classification.

Eccentricity Sum In Trees, Heather Smith, Laszlo A. Szekely, Hua Wang

Mathematical Sciences: Faculty Publications

The eccentricity of a vertex, eccT(v)=maxu∈TdT(v,u), was one of the first, distance-based, tree invariants studied. The total eccentricity of a tree, Ecc(T), is the sum of eccentricities of its vertices. We determine extremal values and characterize extremal tree structures for the ratios Ecc(T)/eccT(u), Ecc(T)/eccT(v), eccT(u)/eccT(v), and eccT(u)/eccT(w) where u,w are leaves of T and v is in the center of T. In addition, we determine the tree structures that minimize and maximize total eccentricity among trees with a given degree sequence.

Improved Estimation Of Optimal Cut-Off Point Associated With Youden Index Using Ranked Set Sampling, Jingjing Yin, Hani M. Samawi, Daniel Linder

Biostatistics: Faculty Publications

A diagnostic cut-off point of a biomarker measurement is needed for classifying a random subject to be either diseased or healthy. However, the cut-off point is usually unknown and needs to be estimated by some optimization criteria. One important criterion is the Youden index, which has been widely adopted in practice. The Youden index, which is defined as the maximum of (sensitivity + specificity −1), directly measures the largest total diagnostic accuracy a biomarker can achieve. Therefore, it is desirable to estimate the optimal cut-off point associated with the Youden index. Sometimes, taking the actual measurements of a biomarker is …

Exploring The Relationship Of Mbd1 Protein Binding Cpg Sites Of Methylated Dna, Shelby L. Scherer

Honors College Theses

Methylated DNA binding (MBD) proteins control transcriptional regulation by binding methylated DNA at CpG islands to modulate transcriptional activation and silencing of specific genes such as tumor suppressors. The goal is to explore the structure/function relationship between MBD proteins and methylated DNA recognition. By synthesizing the methylated DNA binding region of the MBD1 protein, binding studies test the peptide’s affinity and specificity for methylated DNA. Fluorescence, circular dichroism, and thermal denaturation techniques are utilized to determine the binding affinities and structures of peptides. Studies of peptide mutations can monitor the effectiveness of methylated DNA binding compared to the original peptide. …

Population Viability Analysis For Endangered Roanoke Logperch, James Henry Roberts, Paul L. Angermeier, Gregory B. Anderson

Biology: Faculty Publications

A common strategy for recovering endangered species is ensuring that populations exceed the minimum viable population size (MVP), a demographic benchmark that theoretically ensures low long-term extinction risk. One method of establishing MVP is population viability analysis, a modeling technique that simulates population trajectories and forecasts extinction risk based on a series of biological, environmental, and management assumptions. Such models also help identify key uncertainties that have a large influence on extinction risk. We used stochastic count-based simulation models to explore extinction risk, MVP, and the possible benefits of alternative management strategies in populations of Roanoke logperch Percina rex, an …

A Long-Term Study Of Ecological Impacts Of River Channelization On The Population Of An Endangered Fish: Lessons Learned For Assessment And Restoration, James Henry Roberts, Gregory B. Anderson, Paul L. Angermeier

Biology: Faculty Publications

Projects to assess environmental impact or restoration success in rivers focus on project-specific questions but can also provide valuable insights for future projects. Both restoration actions and impact assessments can become “adaptive” by using the knowledge gained from long-term monitoring and analysis to revise the actions, monitoring, conceptual model, or interpretation of findings so that subsequent actions or assessments are better informed. Assessments of impact or restoration success are especially challenging when the indicators of interest are imperiled species and/or the impacts being addressed are complex. From 1997 to 2015, we worked closely with two federal agencies to monitor habitat …

An Industrial Chemical Used In Coal-Washing Influences Plankton Communities In Freshwater Microcosms, Danielle Turner

Honors College Theses

In 2014, 4-methylcyclohexane methanol (MCHM), an industrial chemical used to wash coal, contaminated drinking water in 300,000 homes in West Virginia, USA and raised concerns about toxicity to humans and freshwater ecosystems. The Centers for Disease Control and Prevention determined that a concentration of 1 ppm was safe for human exposure. Despite the concern for human consumption, it is important to determine if MCHM has negative effects on aquatic organisms in contaminated water, particularly plankton communities that comprise the base of freshwater food webs. I exposed freshwater plankton communities in microcosms to 0, 0.5, 1 or 3 ppm MCHM under …
