Since IBL and agricultural education are centered around experiential learning, combining them gives students the opportunity to learn science in a real-world context. However, previous …

Exploration Of The Lived Experiences Of Native American Science Teachers Of The Great Plains: A Narrative Inquiry, Uma Ganesan

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

The complicated history of the education of Native American children through U.S. government-sponsored practices has led to the elimination of the Native children’s sense of Indian identity, culture, and language (Noel, 2002). In addition, increased emphasis on standardization and high-stakes accountability under the No Child Left Behind Act of 2001 has resulted in less culturally responsive educational efforts and more Indigenous students left behind in school systems (Castagno & Brayboy, 2008). This has led to Indigenous students being underrepresented in science, technology, engineering, and mathematics (STEM) fields where they account for only 3% of STEM workers (Fry, Kennedy, & Funk, …

Data was collected between January 2009 and March 2010. In Phase I (Quantitative) the participants (N = 30), selected from ten State University of New York teacher preparation colleges and universities, completed five instruments to quantify the three factors of …

A Case Study Of The Mathematical Learning Of Two Teachers Acquiring Mathematical Knowledge For Teaching, David R. Hartman

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study offers an analysis of the learning of practicing teachers as they acquire a deeper knowledge of mathematics. While some professional developers have shifted part of their focus to helping practicing teachers acquire a deeper knowledge of mathematics (e.g., Stein & Silver, 1996), the results from studies often describe what translates from the professional development experience into classroom practice and measureable gains in student achievement (e.g., Desimone et al., 2002). Studies showing improvements in pedagogy and student learning are important. However, studying what teachers are learning and how they learn is important in developing understanding of the content and …
