Changes In Teacher Thinking And Action In Response To The Next Generation Science Standards, Angela R. Bowden
Changes In Teacher Thinking And Action In Response To The Next Generation Science Standards, Angela R. Bowden
Theses and Dissertations
This study examined the role of K-12 science teachers’ understandings and perceptions of the Next Generation Science Standards, implementation of the new standards in the classroom, and potential barriers to implementation as reform stakeholders had envisioned. Grounded in the relevant literature and working from the Teacher-Centered System Reform framework, this study employed a quantitative approach to data collection. The TCSR Model framed this study by linking teachers’ demographic and professional profile, teaching experience, professional development, district-level, school-level, and classroom-level contexts and illuminates the dynamic effect the factors have on teachers’ thinking and their practice. The study recognizes teachers’ knowledge and …
The Assessment Of Scientific Reasoning Skills Of High School Science Students: A Standardized Assessment Instrument, Shane Hanson
The Assessment Of Scientific Reasoning Skills Of High School Science Students: A Standardized Assessment Instrument, Shane Hanson
Theses and Dissertations
The main goal of science education has been achieving scientific literacy. However, this has been no easy task considering that scientific literacy has many definitions that involve a plethora of activities. This means that assessing the topic becomes quite challenging, especially if this is done with some sort of overarching instrument. Fortunately, Shamos (1995) has characterized the many dimensions of scientific literacy into three levels. These dimensions can then be assessed individually, making the task of assessment less overwhelming. The highest level, true scientific literacy contains dimensions that are discussed in this study, which already have individual assessments. Wenning's Nature …

The Measure And Instruction Of Scale In Introductory Chemistry, Karrie Linn Gerlach
Theses and Dissertations
As a student, it is fundamental to comprehend how small an atom or molecule is in order to truly understand how the world works. The American Association for the Advancement of Science (AAAS) has determined that scale is a critical theme that pervades through all areas of science and is critical to a deep understanding. This project determined that students, which are more proficient with scale and moving between the macroscopic and particle worlds, were better performers in chemistry classes. Interviews were used to determine what the students understood and what common misconceptions were present. These lead to the development …
