Use Of Metaconceptual Scaffolding In The Science Classroom To Promote Conceptual Change, Erin Duez
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 …
Implications Of 3-D Printing For Teaching Geoscience Concepts To Students With Visual Impairments, Karen E. Koehler, Tiffany A. Wild, Sean Tikkun
Implications Of 3-D Printing For Teaching Geoscience Concepts To Students With Visual Impairments, Karen E. Koehler, Tiffany A. Wild, Sean Tikkun
Journal of Science Education for Students with Disabilities
This article presents the results of a study on the use of 3-D printed models in a science classroom for students with visual impairments and examines whether the use of these models impacts student conceptual understanding and misconceptions related to geosciences concepts, specifically plate tectonics.
Data were collected one week prior to instruction, one week after instruction and throughout the 3-week instructional period. Results showed that students with visual impairments held many of the same misconceptions about plate tectonics as students who are typically sighted. All students in this study had fewer misconceptions after the instructional period than they held …
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’ …

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, …

Some Assembly Required: How Scientific Explanations Are Constructed During Clinical Interviews, Bruce L. Sherin, Moshe Krakowski, Victor R. Lee
Instructional Technology and Learning Sciences Faculty Publications
This article is concerned with commonsense science knowledge, the informally-gained knowledge of the natural world that students possess prior to formal instruction in a scientific discipline. Although commonsense science has been the focus of substantial study for more than two decades, there are still profound disagreements about its nature and origin, and its role in science learning. What is the reason that it has been so difficult to reach consensus? We believe that the problems run deep; there are difficulties both with how the field has framed questions and the way that it has gone about seeking answers. In order …
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 …
