Beyond The City Lights: A Multiple-Case Study Of Successful, Experienced Secondary Science Teachers In Rural Schools, Beverly R. Devore-Wedding

Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research

Recruitment and retention concerns for teachers, particularly in rural school districts and in science, fill the daily news and research literature. The shortage of STEM workers is also another concern as well. Then why do nationally recognized secondary science teachers remain in rural schools with lower salaries, increased responsibilities beyond teaching content, and multi-preparations, stay in those schools? How do they overcome challenges in their schools?

This multiple case study focuses on Presidential Award for Excellence in Mathematics and Science Teaching (PAEMST) awardees who have taught secondary science in rural school districts 10 years or more. Eight rural PAEMST high …

Contrast Dependent Knowledge Development In Contrast Supported Scientific Observation, Maura B. Foley

Electronic Theses and Dissertations

Knowledge of contrasts between phenomena can influence how people think and reason about them, so learning contrasts is important in school science. Building knowledge through a process of construction is a common framework through which school science is taught. However, telling phenomena apart through differentiation also plays an important role in learning and may be underused as a teaching framework. An effective way to learn contrasts is to use them to perceptually differentiate similar-looking phenomena presented side-by-side. However, little is known about the persistence/usefulness of knowledge generated during perceptual differentiation over short periods of time and its usage in student …
