Development And Validation Of The Statistics Assessment Of Graduate Students, Dammika Lakmal Walpitage Dec 2016

Development And Validation Of The Statistics Assessment Of Graduate Students, Dammika Lakmal Walpitage

Doctoral Dissertations

This study developed the Statistics Assessment of Graduate Students (SAGS) instrument, and established its preliminary item characteristics, reliability, and validity evidence. Even though there are limited number of assessments available for measuring different aspects of statistical cognition, these previously available assessments have numerous limitations. The SAGS instrument was developed using Rasch modeling approach to create a new measure of statistical research methodology knowledge of graduate students in education and other behavioral and social sciences. Thirty-five multiple-choice questions were written with stems representing applied research situations and response options distinguishing between appropriate use of various statistical tests or procedures. A focus ...


A Criteria-Based Evaluation Of Environmental Literacy Plans In The United States, Karena Ruggiero May 2016

A Criteria-Based Evaluation Of Environmental Literacy Plans In The United States, Karena Ruggiero

Doctoral Dissertations

In response to the lack of formalized environmental education in the United States, 48 states are in the process of developing Environmental Literacy Plans (ELP) through their state environmental education organization (SEEO). The North American Association of Environmental Educators (NAAEE) produced guidelines intended to inform the states writing and development of their ELP. These guidelines provide a framework for the integration of environmental education into current state curricula, propose graduation requirements for environmental literacy, suggest steps for teacher professional development, detail assessment strategies and propose funding sources and policy action steps. Due to large variations in educational systems, policies, and ...


The Impacts Of Curriculum Reform For An Introductory Undergraduate Biology Course Sequence, Anna Jo Juanita Auerbach May 2016

The Impacts Of Curriculum Reform For An Introductory Undergraduate Biology Course Sequence, Anna Jo Juanita Auerbach

Doctoral Dissertations

For decades, educators and policy makers have called for reform in undergraduate biology education to produce a workforce capable of navigating the challenges of society today (NSB, 1986). The American Association for the Advancement of Science (AAAS) outlined recommendations to enact these changes in the Vision and Change in Undergraduate Biology Education final report (AAAS, 2011). These recommendations included restructuring curricula to focus on core biological concepts and competencies, implemented via student-centered practices, with a campus-wide commitment to change, and involving the entire biology community in the reform. The University of Tennessee, Division of Biology, implemented curriculum changes to their ...


Out Of School Time Science Programs: Examining A Program’S Impacts On The Science Identities Of Middle School Female Participants, Elizabeth Ripley Mactavish May 2016

Out Of School Time Science Programs: Examining A Program’S Impacts On The Science Identities Of Middle School Female Participants, Elizabeth Ripley Mactavish

Doctoral Dissertations

Science education reform efforts emphasize teaching science for all Americans, and identify scientific literacy as the principle goal of science education (American Association for the Advancement of Science [AAAS], 1993; National Research Council [NRC], 1996). Despite the goal of scientific literacy, some students, especially females and minorities, consider science irrelevant to their personal interests or career goals. Additionally, research pinpoints middle school as a period when female students begin to lose interest in science (Farenga, 1999; Hill et al., 2010).

Decades of research have documented the gender achievement gap, yet little research has been focused on the science identity gap ...


Understanding Stem Learning Outcomes Using A Phenomenographic Approach, Cheryl L. Brooks Jan 2016

Understanding Stem Learning Outcomes Using A Phenomenographic Approach, Cheryl L. Brooks

Doctoral Dissertations

Today’s STEM professionals are called upon to meet the nation’s technical challenges with innovative technologies that push the boundaries of our current understanding and practices. While the total number of STEM graduates may be sufficient for the number of STEM jobs, many lack the specific competencies needed for practice, suggesting that science and engineering graduates may not be adequately prepared for careers in the STEM fields (U.S. Joint Economic Committee, 2012).

Using a phenomenographical approach, the researcher interviewed 18 STEM professionals to understand the qualitatively different ways in which they gained the technical and professional competencies needed ...


Blended Learning In Chemistry Laboratory Courses: Enhancing Learning Outcomes And Aligning Student Needs With Available Resources, Shayna Brianne Burchett Jan 2016

Blended Learning In Chemistry Laboratory Courses: Enhancing Learning Outcomes And Aligning Student Needs With Available Resources, Shayna Brianne Burchett

Doctoral Dissertations

"Freshman science courses are intended to prepare students for the rigor and expectations of subsequent college science. While secondary education aims to prepare students for the college curriculum, many incoming freshman lack the sense of responsibility for their own learning that is essential for success in a college-level course. The freshman general-chemistry laboratory course at Missouri University of Science and Technology (Missouri S&T) was identified as a bottleneck course with a demand beyond accommodation capacity. To address the bottleneck and develop a sense of learner responsibility, a decision was made to investigate laboratory course delivery strategies. As a result ...


Training In Summarizing Notes: Effects Of Teaching Students A Self-Regulation Study Strategy In Science Learning, Michelle Mendoza Nebres Jan 2016

Training In Summarizing Notes: Effects Of Teaching Students A Self-Regulation Study Strategy In Science Learning, Michelle Mendoza Nebres

Doctoral Dissertations

The last two decades of national data assessments reveal that there has been a sharp decline in nationwide standardized test scores. International assessment data show that in 2012 a very low amount of American students were performing at proficiency or above in science literacy. Research in science literacy education suggests that students benefit most when they are self-regulated (SR) learners. Unfortunately, SR poses a challenge for many students because students lack these skills. The effects of having learned few SR strategies at an early age may lead to long term learning difficulties—preventing students from achieving academic success in college ...


A Moving Imagination In Spaces Of Distress: Teacher And Student Agency In A Science Classroom, Annie Sunshine Adamian Jan 2016

A Moving Imagination In Spaces Of Distress: Teacher And Student Agency In A Science Classroom, Annie Sunshine Adamian

Doctoral Dissertations

This qualitative study explored the ways in which our classroom community (students and teacher) engaged with humanizing pedagogy in a seventh grade science classroom, toward the full development (e.g. personal, social, emotional, academic) of our classroom community, and the dismantling of inequitable practices and unjust policies that we recognized in our science classroom, school and/or community while utilizing the process of teacher and student participatory action research (tsPAR) (Adamian, 2015) and Critical Race Praxis for Educational Research (CRP-Ed) (Jayakumar & Adamian, 2015).

This study examined the complexities of mutually engaging across differing positionalities while intentionally working in spaces of ...
