Aakash Kumar – ProQuest LLC, 2022
Many efforts to reform science educational standards and structure have placed an emphasis on directing learners to communicate about concepts using external representations (ERs). Techniques to develop competencies with ERs often ask learners to develop understanding outside of a physical context while concurrently making connections back to the…

Scannell, Stephen Godfrey – ProQuest LLC, 2019
This dissertation is a case study of a school district in the Pacific Northwest that developed three-year high school science curricula using a Physics First course sequence (Physics, Chemistry, Biology), with the crosscutting concept "Patterns" as the central theme of the courses. The purpose of the study was to examine the impact of…

Fouche, Jaunine – ProQuest LLC, 2013
The purpose of this nonequivalent control group design study was to evaluate the effectiveness of metacognitive and self-regulatory strategy use on the assessment achievement of 215 9th-grade, residential physics students from low socioeconomic status (low-SES) backgrounds. Students from low-SES backgrounds often lack the self-regulatory habits…

LaFever, Karen M. – ProQuest LLC, 2012
Co-teaching is a method that is increasing within schools across the US as educators strive to leave no child behind. It is a costly method, having two paid instructors in one classroom, with an average of 24 students shared between them. If it significantly increases the achievement of all students, it is well worth the costs involved. However,…

West, Andrew – ProQuest LLC, 2011
The purpose of this study was to explore and identify the experiences that informed the development of three veteran (15+ years of teaching experience) 9th grade physics teachers' specialized knowledge, or PCK, for using representations to teach the topics of energy transformation and transfer. Through the lens of phenomenography, the study…

Lewis, Anna – ProQuest LLC, 2008
This study examined science textbooks over time to better understand the "science content" expectations that the U.S. educational system deems appropriate for 8th and 9th grade science students. The study attempted to answer the questions: (1) What specific science content has been presented via the textbook from 1952 to 2008? (2) Within…
