Examining Preservice Science Teacher Understanding Of Nature Of Science: Discriminating Variables On The Aspects Of Nature Of Science, William I. Jones

Faculty Dissertations

This study examined the understanding of nature of science among participants in their final year of a 4-year undergraduate teacher education program at a Midwest liberal arts university. The Logic Model Process was used as an integrative framework to focus the collection, organization, analysis, and interpretation of the data for the purpose of (1) describing participant understanding of NOS and (2) to identify participant characteristics and teacher education program features related to those understandings. The Views of Nature of Science Questionnaire form C (VNOS-C) was used to survey participant understanding of 7 target aspects of Nature of Science (NOS). A ...


The Construction Of A Chinese Mri Brain Atlas: A Morphometric Comparison Study Between Chinese And Caucasian Cohorts, Ivo Dinov 2009 UCLA

The Construction Of A Chinese Mri Brain Atlas: A Morphometric Comparison Study Between Chinese And Caucasian Cohorts, Ivo Dinov

Ivo D Dinov

We developed a novel brain atlas template to facilitate computational brain studies of Chinese subjects and populations using high quality magnetic resonance imaging (MRI) and well-validated image analysis techniques. To explore the ethnicity-based structural brain differences, we used the MRI scans of 35 Chinese male subjects (24.03 ± 2.06 years) and compared them to an age-matched cohort of 35 Caucasian males (24.03 ± 2.06 years). Global volumetric measures were used to identify significant group differences in the brain length, width, height and AC–PC line distance. Using the LONI BrainParser, 56 brain structures were automatically labeled and analyzed ...


Mathematical Communication And Its Relation To The Frequency Of Manipulative Use., Karl Kosko, Jesse Wilkins 2009 Virginia Polytechnic Institute and State University

Mathematical Communication And Its Relation To The Frequency Of Manipulative Use., Karl Kosko, Jesse Wilkins

Karl W Kosko

Many studies on manipulatives describe communication in mathematics as a component for properly implementing manipulatives in the classroom. However, no empirical research is available to support this relationship. Secondary analysis of data collected by the National Center for Educational Statistics from the Early Childhood Longitudinal Study was used to examine whether a relationship between students’ manipulative use and communication in mathematics learning exists. Correlational analyses found a significant relationship between students’ verbal and written communication and manipulative use.

Robust Surface Reconstruction Via Laplace-Beltrami Eigen-Projection And Boundary Deformation, Ivo Dinov 2009 University of Michigan - Ann Arbor

Robust Surface Reconstruction Via Laplace-Beltrami Eigen-Projection And Boundary Deformation, Ivo Dinov

Ivo D Dinov

In medical shape analysis, a critical problem is reconstructing a smooth surface of correct topology from a binary mask that typically has spurious features due to segmentation artifacts. The challenge is the robust removal of these outliers without affecting the accuracy of other parts of the boundary. In this paper, we propose a novel approach for this problem based on the Laplace-Beltrami (LB) eigen-projection and properly designed boundary deformations. Using the metric distortion during the LB eigen-projection, our method automatically detects the location of outliers and feeds this information to a well-composed and topology-preserving deformation. By iterating between these two ...


“Theoric Transformations” And A New Classification Of Abductive Inferences, Michael Hoffmann 2009 Georgia Institute of Technology - Main Campus

“Theoric Transformations” And A New Classification Of Abductive Inferences, Michael Hoffmann

Michael H.G. Hoffmann

Based on a definition of “abductive insight” and a critical discussion of G. Schurz’s (2008) distinction of eleven “patterns of abduction” that he organizes in four groups, I suggest an even more comprehensive classification that distinguishes 15 forms in an alternative structure. These forms are organized, on the one hand, with regard to what is abductively inferred—singular facts; types; laws; theoretical models; or representation systems—and, on the other, with regard to the question whether the abductive procedure is selective or creative (including a distinction between “psychologically creative,” as in school learning, or “historically creative”). Moreover, I argue ...

Carlos Andrés Naranjo Martínez

Teniendo cada ciudadano la posibilidad de elegir y ser elegido, es natural preguntarse cuál método utilizar para votar y elegir, y cómo hacer para que con ese método se pueda determinar quién o quiénes son los elegidos. De éstas preguntas se han ocupado la ciencia política y las matemáticas, al punto que hoy en día existen varios sistemas electorales propuestos y aplicados.


Neuroimaging Study Designs, Computational Analyses And Data Provenance Using The Loni Pipeline, Ivo Dinov 2009 University of Michigan - Ann Arbor

Neuroimaging Study Designs, Computational Analyses And Data Provenance Using The Loni Pipeline, Ivo Dinov

Ivo D Dinov

Modern computational neuroscience employs diverse software tools and multidisciplinary expertise to analyze heterogeneous brain data. The classical problems of gathering meaningful data, fitting specific models, and discovering appropriate analysis and visualization tools give way to a new class of computational challenges—management of large and incongruous data, integration and interoperability of computational resources, and data provenance. We designed, implemented and validated a new paradigm for addressing these challenges in the neuroimaging field. Our solution is based on the LONI Pipeline environment [3], [4], a graphical workflow environment for constructing and executing complex data processing protocols. We developed study-design, database and ...


Brain Mri Tissue Classification Based On Local Markov Random Fields, Ivo Dinov 2009 University of Michigan - Ann Arbor

Brain Mri Tissue Classification Based On Local Markov Random Fields, Ivo Dinov

Ivo D Dinov

A new method for tissue classification of brain magnetic resonance images (MRI) of the brain is proposed. The method is based on local image models where each models the image content in a subset of the image domain. With this local modeling approach, the assumption that tissue types have the same characteristics over the brain needs not to be evoked. This is important because tissue type characteristics, such as T1 and T2 relaxation times and proton density, vary across the individual brain and the proposed method offers improved protection against intensity non-uniformity artifacts that can hamper automatic tissue classification methods ...

Codes Declassified: The Stories, Kalvin Whittles

Kalvin Whittles Dr.

One of the recommendations of the doctoral study, Cryptology: A didactical transposition into a grade 10 school mathematics classroom is to place the topic of cryptology in the public domain. The book Codes declassified: The stories aims to do so through stories to introduce readers to some of the codes in cryptology.


A Commonly Carried Allele Of The Obesity-Related Fto Gene Is Associated With Reduced Brain Volume In The Healthy Elderly, Ivo Dinov 2009 University of Michigan - Ann Arbor

A Commonly Carried Allele Of The Obesity-Related Fto Gene Is Associated With Reduced Brain Volume In The Healthy Elderly, Ivo Dinov

Ivo D Dinov

A recently identified variant within the fat mass and obesity-associated (FTO) gene is carried by 46% of Western Europeans and is associated with an ~1.2 kg higher weight, on average, in adults and an ~1 cm greater waist circumference. With >1 billion overweight and 300 million obese persons worldwide, it is crucial to understand the implications of carrying this very common allele for the health of our aging population. FTO is highly expressed in the brain and elevated body mass index (BMI) is associated with brain atrophy, but it is unknown how the obesity-associated risk allele affects human brain ...

Coherence, Contradiction And The Development Of School Science Identities, Stacy Olitsky, Linda Loman, Jessica Gardner, Markita Billups

Stacy Olitsky

This ethnographic study took place in a diverse eighth grade science classroom in an urban magnet school where students demonstrate significant variation in classroom achievement and participation. In this paper, we use an activity-theoretical framework to examine classroom events in order to identify and work toward reducing contradictions that can interfere with students developing positive school science identities. We discuss several contradictions for students in this classroom, including the conflicts between social and academic goals and the inconsistencies between science and math classes. We found that in situations where students could build and use social capital through learning science, they ...
