Conceptualization And Perceptions Of Student Preparedness In Quantitative Reasoning Among Introductory Biology Faculty, Ann Cleveland
Conceptualization And Perceptions Of Student Preparedness In Quantitative Reasoning Among Introductory Biology Faculty, Ann Cleveland
Electronic Theses and Dissertations
Quantitative reasoning (QR) is a crucial competency as undergraduate biology students complete their academic program and enter a workforce increasingly reliant on analyses of vast and complex data sets. The need to prepare biology majors for the 21st century workforce was cited in Vision and Change: a Call to Action (American Association for the Advancement of Science [AAAS], 2011). The Vision and Change document also advocated for curriculum reform to incorporate QR instruction in undergraduate biology programs. Biology education researchers answered this call with a wealth of research examining undergraduate QR competencies, barriers and challenges to QR learning in …
The Impact Of A Five-Day Number Sense Intervention On High School Student's Quantitative Reasoning Skills And Self-Efficacy, Rebecca Steele-Mackey
The Impact Of A Five-Day Number Sense Intervention On High School Student's Quantitative Reasoning Skills And Self-Efficacy, Rebecca Steele-Mackey
Dissertations
Understanding numerical quantities and applying this knowledge in practical applications is essential throughout life. A well-developed number sense comes from learning foundational skills and continuing to rely on these skills and concepts in higher mathematical education as well as in adulthood. Prior research shows that K-8 students lack a conceptual understanding of fraction, decimal, and percentage concepts (NCTM, 2009). While there is literature that identifies a deficit in these mathematical areas, there is a need to examine possible activities and interventions that can be performed throughout secondary education courses that support growth in students' conceptual understanding of rational number concepts. …
Investigating Elementary School Students’ Reasoning About Dynamic Angles, Erell Germia
Investigating Elementary School Students’ Reasoning About Dynamic Angles, Erell Germia
Theses, Dissertations and Culminating Projects
Angle measurement is a significant topic in almost all areas of mathematics learning and also in many disciplines outside mathematics education, such as engineering and architecture. According to the literature, there are three common conceptions of angles – as union of rays, rotations, and wedges. Researchers argued that students must consider these three angle concepts together to construct a meaningful understanding of angles. However, the curriculum standards for mathematics often present these angle conceptions separately to students, probably resulting in a fragmented understanding of the angle concept. In addition to this problem, the research literature documents multiple alternative conceptions that …
