We've Got The 'Hots' For Changing Teacher Misconceptions Of Learning Styles: A Mixed-Methods Approach., Allison Paige Fowler
We've Got The 'Hots' For Changing Teacher Misconceptions Of Learning Styles: A Mixed-Methods Approach., Allison Paige Fowler
Electronic Theses and Dissertations
In this dissertation I added to the literature surrounding the myth that teachers should cater to students’ learning styles to improve learning outcomes. I operated from the “hot” paradigm for conceptual change, through the use of the Cognitive Reconstruction of Knowledge Model (CRKM) as the theoretical framework to examine teachers’ conceptual change about learning styles. More specifically, I considered teachers’ existing conceptions as related to their essentialist beliefs, as well as how their motivation and the content of the message contribute to conceptual change. I also responded to the literature on teacher perceptions of researchers by examining the use of …

Use Of Metaconceptual Scaffolding In The Science Classroom To Promote Conceptual Change, Erin Duez
Education Dissertations
The purpose of this study was to analyze the effects of providing metaconceptual awareness questions on the conceptual change and metaconceptual awareness of students in the chemistry classroom. This quasi-experimental study with a repeated-measures design analyzed the effects of providing metaconceptual awareness questions on the conceptual change and metaconceptual awareness of high school chemistry students. The intervention consisted of providing metaconceptual awareness questions nine times to the experimental group over a three-week period. The chemistry conceptual knowledge of both groups was assessed three times: pretest, posttest, and a delayed retention test. The metaconceptual awareness of the students was assessed twice …
Effects Of Explicit-Reflective Instruction On Preservice And Novice Teachers’ Epistemic And Conceptual Change Mediated By Reasoning, Danny Murphy
UNLV Theses, Dissertations, Professional Papers, and Capstones
Teachers’ beliefs shape their daily instruction and the materials presented to students. The personal views of educators are especially relevant when socioscientific issues are involved. Preservice and novice teachers’ mastery of the nature of science (NOS) and personal beliefs in and out of the classroom influence their worldviews and classroom practices. Although research has been conducted regarding conceptual change and epistemic change, it is not understood how conceptual change and epistemic change affect instructional practice. The purpose of the mixed methods explanatory sequential study was to determine how students in a science methods classroom think and reason with explicit and …
More Bang For Your Buck: Bolstering Learning Via Refutation Text With Refutation-Based Elaborated Feedback, Jacqueline R. Cordova
More Bang For Your Buck: Bolstering Learning Via Refutation Text With Refutation-Based Elaborated Feedback, Jacqueline R. Cordova
UNLV Theses, Dissertations, Professional Papers, and Capstones
The current study examines the effects of refutation text and refutation-based elaborated feedback on conceptual understanding, self-efficacy, interest, beliefs, attitudes, and knowledge, within the context of learning about climate change. The study also tests whether elaborated feedback moderates the refutation text effect through an interaction. One hundred and fifty nine undergraduate students were recruited to participate in this study, which was administered via computer. They completed measures of their self-efficacy and interest in learning about climate change, as well as climate change beliefs, attitudes, and knowledge. Approximately half of the participants read a refutation text and half read a comparison …
Preservice Science Teachers’ Pedagogical Content Knowledge For Nature Of Science And Nature Of Scientific Inquiry: A Successful Case Study, Gunkut Mesci
Dissertations
The purpose of this dissertation project is to explore preservice science teachers’ development of pedagogical content knowledge (PCK) for targeted aspects of nature of science (NOS) and nature of scientific inquiry (NOSI). Through multiple data sources, it is examined how preservice science teachers’ understanding of NOS and NOSI have changed over the program, and manifests itself in their classroom practice. This is an exploratory multiple case study of participants’ experiences and developments during a teacher development program. Data is collected in the form of open-ended surveys, interviews, observations, lesson plans, video materials, and teaching documents. After all data is collected, …
What’S In A Gene: Undergraduates’ Ideas And Misconceptions About Gene Function, Justin M. Levaughn
What’S In A Gene: Undergraduates’ Ideas And Misconceptions About Gene Function, Justin M. Levaughn
Theses and Dissertations--Science, Technology, Engineering, and Mathematics (STEM) Education
The purpose of this study was to field test a two-tiered instrument including multiple-choice and short answer tasks to assess college students’ ideas and level of understanding in genetics. The instrument was constructed from previously tested assessment tasks and findings from the current research literature. Ninety-seven freshmen enrolled in a biology lab course were surveyed. Test validity and reliability were measured using Chronbach coefficients. Multiple-choice and short answer responses were analyzed using descriptive statistics to identify frequencies of answer selections. Written responses were independently evaluated using a five-point scoring rubric by three researchers to identify common misconceptions revealed in students’ …
The Outcomes Of New Teachers Being Reflective, John Whittington Seddon
The Outcomes Of New Teachers Being Reflective, John Whittington Seddon
Theses: Doctorates and Masters
New university teachers are typically advancing scholars who have recently commenced academic teaching duties. Referred to as neophytes in this study, these teachers are usually early career academics, postgraduate students or sessional lecturers who begin teaching with little more training than attendance at short professional development courses or seminars. Their teaching and learning theories are generally naive and their practice is often limited. In view of the already substantiated connections that have been found between teachers’ conceptions of teaching (COTs) and their practical approaches to teaching, the COTs held by neophytes are of consequence, as they are usually indicative of …
Students' Conceptions About Climate Change: Using Critical Evaluation To Influence Plausibility Reappraisals And Knowledge Reconstruction, Doug Lombardi
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Intergovernmental Panel on Climate Change (2007) reported a greater than 90% chance that human activities are responsible for global temperature increases over the last 50 years, as well as other climatic changes. The scientific report also states that alternative explanations (e.g., increasing energy received from the Sun) are less plausible than human-induced climate change. These climate scientists have made their plausibility judgment--which I define as the relative potential truthfulness of alternative explanations--based on the evaluation and coordination of multiple lines evidence with competing theoretical perspectives.
Climate change is a highly relevant and gravely serious topic; in an educational setting, …
Effect Of Process-Oriented Guided-Inquiry Learning On Non-Majors Biology Students' Understanding Of Biological Classification, Breann Marie Wozniak
Effect Of Process-Oriented Guided-Inquiry Learning On Non-Majors Biology Students' Understanding Of Biological Classification, Breann Marie Wozniak
All Graduate Theses, Dissertations, and Other Capstone Projects
The purpose of this study was to examine the effect of process-oriented guided-inquiry learning (POGIL) on non-majors college biology students' understanding of biological classification. This study addressed an area of science instruction, POGIL in the non-majors college biology laboratory, which has yet to be qualitatively and quantitatively researched. A concurrent triangulation mixed methods approach was used. Students' understanding of biological classification was measured in two areas: scores on pre and posttests (consisting of 11 multiple choice questions), and conceptions of classification as elicited in pre and post interviews and instructor reflections. Participants were Minnesota State University, Mankato students enrolled in …
Elementary And Secondary Science Teachers Negotiation Of Controversial Science Content: The Relationships Among Prior Conception Appropriation, Thinking Disposition, And Learning About Geologic Time, James Harold Roberson
Elementary And Secondary Science Teachers Negotiation Of Controversial Science Content: The Relationships Among Prior Conception Appropriation, Thinking Disposition, And Learning About Geologic Time, James Harold Roberson
Doctoral Dissertations
A major component of the values people place on science and their attitude toward it is their openness to new ideas or overall open-mindedness. An individual’s values and attitudes become integrally connected to their prior knowledge and conceptions regarding science and science content. Sometimes the nature of a natural phenomenon and the scientific explanation for the phenomenon is controversial. A controversial scientific concept is one that evokes emotion and forces individuals to assess the values associated with this content and make assessments of their attitudes toward it. This is especially true during learning. The purpose of this study was to …
Effects Of Student Ontological Position On Cognition Of Human Origins, Jeremy Ervin
Effects Of Student Ontological Position On Cognition Of Human Origins, Jeremy Ervin
Faculty Dissertations
In this study, the narratives from a hermeneutical dialectic cycle of three high school students were analyzed to understand the influences of ontological position on the learning of human origins. The interpretation of the narratives provides the reader an opportunity to consider the learning process from the perspective of worldview and conceptual change theories. Questions guiding this research include: Within a context of a worldview, what is the range of ontological positions among a high school AP biology class? To what extent does ontological position influence the learning of scientific concepts about human origins? If a student’s ontological position is …
