Acoustic Signatures Of Habitat Types In The Miombo Woodlands Of Western Tanzania, Sheryl Vanessa Amorocho, Dante Francomano, Kristen M. Bellisario, Ben Gottesman, Bryan C. Pijanowski Aug 2017

Acoustic Signatures Of Habitat Types In The Miombo Woodlands Of Western Tanzania, Sheryl Vanessa Amorocho, Dante Francomano, Kristen M. Bellisario, Ben Gottesman, Bryan C. Pijanowski

The Summer Undergraduate Research Fellowship (SURF) Symposium

The Miombo Woodlands of Tanzania comprise several habitat types that are home to a great number of flora and fauna. Understanding their responses to increasing human disturbance is important for conservation, especially in places where people depend so directly on their local ecosystem services to survive. Soundscapes are a powerful approach to study complex biomes undergoing change. The sounds emitted by soniferous fauna characterize the acoustic profile of the landscapes they inhabit such that habitats with the highest acoustic abundance are considered as the most diverse and possibly more ecologically resilient. However, acoustic variability within similar habitat types may pose …


Parallelization Of Molecular Docking Algorithms Using Cuda For Use In Drug Discovery, Brandon Stewart, Jonathan Fine, Gaurav Chopra Phd Aug 2017

Parallelization Of Molecular Docking Algorithms Using Cuda For Use In Drug Discovery, Brandon Stewart, Jonathan Fine, Gaurav Chopra Phd

The Summer Undergraduate Research Fellowship (SURF) Symposium

Traditional drug discovery methodology uses a multitude of software packages to design and evaluate new drug-like compounds. While software packages implement a wide variety of methods, the serial (i.e. single core) implementation for many of these algorithms, prohibit large scale docking, such as proteome-wide docking (i.e. thousands of compounds with thousands of proteins). Several docking algorithms can be parallelized, significantly reducing the runtime of the calculations, thus enabling large-scale docking. Implementing algorithms that take advantage of the distributed nature of graphical processing units (GPUs) via the Compute Unified Device Architecture (CUDA) enables us to efficiently implement massively parallel algorithms. Two …


Stability Analysis Of A Flexible Vehicle Model Controlled By Human Pilot Models, Abhishek Ajmani, Anil Bajaj Aug 2017

Stability Analysis Of A Flexible Vehicle Model Controlled By Human Pilot Models, Abhishek Ajmani, Anil Bajaj

The Summer Undergraduate Research Fellowship (SURF) Symposium

There is a constant race among automobile manufactures to design safer vehicles while minimizing weight to reduce power consumption. Additionally, organizations like NASA and SpaceX are persistently working toward creating reliable, lightweight rovers to be used on the surface of Mars. However, the lightweight requirement often increases vehicle flexibility, which further develops a tendency toward instability in the lateral (sideways) direction. This investigation develops a mathematical model that represents the dynamics of a flexible vehicle in forward motion, and a heuristic human pilot model is proposed which controls the vehicle. Following such formulation, the combined vehicle and pilot model is …


Temperature-Dependent Exciton Dynamics Of Superacid Treatment In Monolayers Of The Metal Dichalcogenide Mos2, Mingwei Zhou, Long Yuan, Jordan Snaider, Libai Huang Aug 2017

Temperature-Dependent Exciton Dynamics Of Superacid Treatment In Monolayers Of The Metal Dichalcogenide Mos2, Mingwei Zhou, Long Yuan, Jordan Snaider, Libai Huang

The Summer Undergraduate Research Fellowship (SURF) Symposium

To improve optoelectronic semiconductor materials, one of the most efficient research areas is the two-dimensional (2D) transition-metal dichalocogenides (TMDCs). It has been shown that organic nonoxidizing superacid bis(trifluoromethane)sulfonamide (TFSI) treatment of molybdenum disulfide (MoS2) monolayer could uniformly enhance its photoluminescence by more than two orders of magnitude and also extend the lifetime of excitons. This could greatly improve the efficiency of the solar energy usage, but the mechanism behind it has not been fully understood. Extreme low temperatures (approximately 7K), which slow the surface exciton mobility, were applied to investigate the changes of treated MoS2 monolayer surfaces. …


Machine Learning Based Molecular Properties Discovery For Quantum-Chemical Simulations, Jijie Zhou, Nickolas D. Winovich, Guang Lin Aug 2017

Machine Learning Based Molecular Properties Discovery For Quantum-Chemical Simulations, Jijie Zhou, Nickolas D. Winovich, Guang Lin

The Summer Undergraduate Research Fellowship (SURF) Symposium

In molecular quantum mechanics, mappings between molecular structures and their corresponding physical and chemical properties greatly influence the accuracy of simulation for chemical interactions at the quantum level. Based on the information of molecular structure-property mappings, researchers could use the mappings to assemble and build new materials with certain molecular properties in the future. Scientists used density functional theory (DFT)-based methods for predicting material behavior. However, the accuracy of using DFT-based models is highly restricted since the methods are usually designed based on specific molecules, and thus when it is applied to large-scale simulations, the accuracy is unpredictable. Recently, machine …

How To Enhance Interdisciplinary Competence—Interdisciplinary Problem-Based Learning Versus Interdisciplinary Project-Based Learning, Mirjam Brassler, Jan Dettmers Jul 2017

How To Enhance Interdisciplinary Competence—Interdisciplinary Problem-Based Learning Versus Interdisciplinary Project-Based Learning, Mirjam Brassler, Jan Dettmers

Interdisciplinary Journal of Problem-Based Learning

Interdisciplinary competence is important in academia for both employability and sustainable development. However, to date, there are no specific interdisciplinary education models and, naturally, no empirical studies to assess them. Since problem-based learning (PBL) and project-based learning (PjBL) are learning approaches that emphasize students’ collaboration, both pedagogies seem suitable to enhance students’ interdisciplinary competence. Based on the principle of constructive alignment and four instructional principles on interdisciplinary learning, this paper proposes that students profit more from interdisciplinary PBL (iPBL) than interdisciplinary PjBL (iPjBL). A pre-post study was conducted with a sample of 95 students participating in iPBL and 183 students …


Algorithmic Puzzles: History, Taxonomies, And Applications In Human Problem Solving, Anany Levitin Jul 2017

Algorithmic Puzzles: History, Taxonomies, And Applications In Human Problem Solving, Anany Levitin

The Journal of Problem Solving

The paper concerns an important but underappreciated genre of algorithmic puzzles, explaining what these puzzles are, reviewing milestones in their long history, and giving two different ways to classify them. Also covered are major applications of algorithmic puzzles in cognitive science research, with an emphasis on insight problem solving, and the advantages of algorithmic puzzles over some other classes of problems used in insight research. The author proposes adding algorithmic puzzles as a separate category of insight problems, suggests 12 specific puzzles that could be useful for research in insight problem solving, and outlines several experiments dealing with other cognitive …


A Pattern Approach To Examine The Design Space Of Spatiotemporal Visualization, Chen Guo Jul 2017

A Pattern Approach To Examine The Design Space Of Spatiotemporal Visualization, Chen Guo

Department of Computer Graphics Technology Degree Theses

Pattern language has been widely used in the development of visualization systems. This dissertation applies a pattern language approach to explore the design space of spatiotemporal visualization. The study provides a framework for both designers and novices to communicate, develop, evaluate, and share spatiotemporal visualization design on an abstract level. The touchstone of the work is a pattern language consisting of fifteen design patterns and four categories. In order to validate the design patterns, the researcher created two visualization systems with this framework in mind. The first system displayed the daily routine of human beings via a polygon-based visualization. The …


Biomechanics Of Snoring And Sleep Apnea, Charles F. Babbs Jul 2017

Biomechanics Of Snoring And Sleep Apnea, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

To understand the mechanisms of snoring and sleep apnea a first-principles biomechanical analysis was done for airflow through branched parallel channels, separated by a freely movable soft palate, and converging to a common channel at the base of the tongue in a “Y-shaped” configuration. Branches of the Y describe slit-like passages on the nasal and oral sides of the soft palate, when the palate is pushed by backward movement of the tongue to form a wedge between the tongue surface and the posterior pharyngeal wall. The common channel of the Y describes the oropharyngeal passage between the base of the …


Getting Started With Pbl—A Reflection, Tanja Müller, Thomas Henning Jul 2017

Getting Started With Pbl—A Reflection, Tanja Müller, Thomas Henning

Interdisciplinary Journal of Problem-Based Learning

In this paper, we provide insight into the PBL project called PoLiMINT (Problem-oriented Learning in MINT). The project is located at the Bremen University of Applied Sciences and aims to introduce and foster PBL in the introductory phase of a physics study program. Concerning our general conditions, we will present our incremental implementation strategy and address the first elementary steps. In order to demonstrate our Scholarship of Teaching and Learning mode of reflecting the implementation process, we examine selected instructional and pedagogical difficulties and our problem-solving more closely.


Undertaking Educational Research Following The Introduction, Implementation, Evolution, And Hybridization Of Constructivist Instructional Models In An Australian Pbl High School, Adam Hendry, Gavin Hays, Kurt Challinor, Daniel Lynch Jul 2017

Undertaking Educational Research Following The Introduction, Implementation, Evolution, And Hybridization Of Constructivist Instructional Models In An Australian Pbl High School, Adam Hendry, Gavin Hays, Kurt Challinor, Daniel Lynch

Interdisciplinary Journal of Problem-Based Learning

The aim of this paper is to provide an overview of the introduction, implementation, evolution, hybridization, and initial research into the constructivist instructional models deployed within a secondary (high) school in Australia. A concomitant aim is to relate some of the consequences of whole school pedagogical change, which have included the implementation of project- and problem-based learning, the flipped classroom, and a derivative hybridized form, referred to here as “flipped PBL.” Moreover, after a decade of using constructivist approaches, we initiated educational research to better understand some of the effects of these changes and to explore the reasons behind the …


Mathematical Description And Mechanistic Reasoning: A Pathway Toward Stem Integration, Paul J. Weinberg Jul 2017

Mathematical Description And Mechanistic Reasoning: A Pathway Toward Stem Integration, Paul J. Weinberg

Journal of Pre-College Engineering Education Research (J-PEER)

Because reasoning about mechanism is critical to disciplined inquiry in science, technology, engineering, and mathematics (STEM) domains, this study focuses on ways to support the development of this form of reasoning. This study attends to how mechanistic reasoning is constituted through mathematical description. This study draws upon Smith’s (2007) characterization of mathematical description of scientific phenomena as ‘‘bootstrapping,’’ where negotiating the relationship between target phenomena and represented relations is fundamental to learning. In addition, the development of mathematical representation presents a viable pathway towards STEM integration. In this study, participants responded to an assessment of mechanistic reasoning while cognitive interviews …


Understanding The Impact Of Strategic Team Formation In Early Programming Education, Tony A. Lowe, Sean B. Brophy Jun 2017

Understanding The Impact Of Strategic Team Formation In Early Programming Education, Tony A. Lowe, Sean B. Brophy

School of Engineering Education Graduate Student Series

This evidence based research looks at the impact of a team-based instruction on learning to program in a first year engineering course designed under the Bauhaus studio model. Each team is formulated with a “more knowledgeable other” [1], or for this paper the “ringer” based on selfreported prior learning. The ringer is intended to support the team through early programming challenges. In addition to the professor and teaching assistants, having a peer mentor can yield higher satisfaction and confidence in learners [2]. Our analysis evaluates learning outcomes as student progress through the term, comparing performance based on the performance and …


Teachers’ Incorporation Of Argumentation To Support Engineering Learning In Stem Integration Curricula, Corey A. Mathis, Emilie A. Siverling, Aran W. Glancy, Tamara J. Moore Jun 2017

Teachers’ Incorporation Of Argumentation To Support Engineering Learning In Stem Integration Curricula, Corey A. Mathis, Emilie A. Siverling, Aran W. Glancy, Tamara J. Moore

Journal of Pre-College Engineering Education Research (J-PEER)

One of the fundamental practices identified in Next Generation Science Standards (NGSS) is argumentation, which has been researched in P-12 science education for the previous two decades but has yet to be studied within the context of P-12 engineering education. This research explores how elementary and middle school science teachers incorporated argumentation into engineering design-based STEM (science, technology, engineering, and mathematics) integration curricular units they developed during a professional development program. To gain a better understanding of how teachers included argumentation in their curricula, a multiple case study approach was conducted using four STEM integration units. While evidence of argumentation …

Students’ Successes And Challenges Applying Data Analysis And Measurement Skills In A Fifth-Grade Integrated Stem Unit, Aran W. Glancy, Tamara J. Moore, Selcen Guzey, Karl A. Smith

Journal of Pre-College Engineering Education Research (J-PEER)

An understanding of statistics and skills in data analysis are becoming more and more essential, yet research consistently shows that students struggle with these concepts at all levels. This case study documents some of the struggles four groups of fifth-grade students encounter as they collect, organize, and interpret data and then ultimately attempt to draw conclusions or make decisions based on these data. The activities in which the students engaged were part of an integrated science, technology, engineering, and mathematics (STEM) unit that had students collecting and analyzing data both in the context of learning science concepts and in the …


Perspectives On Failure In The Classroom By Elementary Teachers New To Teaching Engineering, Pamela S. Lottero-Perdue, Elizabeth A. Parry Jun 2017

Perspectives On Failure In The Classroom By Elementary Teachers New To Teaching Engineering, Pamela S. Lottero-Perdue, Elizabeth A. Parry

Journal of Pre-College Engineering Education Research (J-PEER)

This mixed methods study examines perspectives on failure in the classroom by elementary teachers new to teaching engineering. The study participants included 254 teachers in third, fourth, and fifth grade who responded to survey questions about failure, as well as a subset of 38 of those teachers who participated in interviews about failure. The study first examines the literature about failure in the contexts of engineering and education. Failure is positioned as largely normative and expected in engineering, whereas in education, learning and failure have a more tenuous relationship. Identity, failure avoidance, failure as part of the learning process, growth …


Undergraduate Engineers And Teachers: Can Students Be Both?, Malinda S. Zarske, Maia L. Vadeen, Janet Y. Tsai, Jacquelyn F. Sullivan, Denise W. Carlson Jun 2017

Undergraduate Engineers And Teachers: Can Students Be Both?, Malinda S. Zarske, Maia L. Vadeen, Janet Y. Tsai, Jacquelyn F. Sullivan, Denise W. Carlson

Journal of Pre-College Engineering Education Research (J-PEER)

Today’s college-aged students are graduating into a world that relies on multidisciplinary talents to succeed. Engineering college majors are more likely to find jobs after college that are outside of STEM (science, technology, engineering, and mathematics) fields, including jobs in healthcare, management, and social services. A survey of engineering undergraduate students at the University of Colorado Boulder in November 2012 indicated a desire by students to simultaneously pursue secondary teacher licensure alongside their engineering degrees: 25 percent ‘‘agreed’’ or ‘‘strongly agreed’’ that they ‘‘would be interested in earning grades 7–12 science or math teaching licenses while [they] earn [their] engineering …


Examining Experienced Teachers’ Noticing Of And Responses To Students’ Engineering, Aaron W. Johnson, Kristen B. Wendell, Jessica Watkins Jun 2017

Examining Experienced Teachers’ Noticing Of And Responses To Students’ Engineering, Aaron W. Johnson, Kristen B. Wendell, Jessica Watkins

Journal of Pre-College Engineering Education Research (J-PEER)

Engineering design places unique demands on teachers, as students are coming up with new, unanticipated ideas to problems along often unpredictable trajectories. These demands motivate a responsive approach to teaching, in which teachers attend their students’ thinking and flexibly adapt their instructional plans and objectives. A great deal of literature has focused on responsive teaching in science and mathematics, but there has been little research or professional development on this approach in engineering. In this work, we conducted clinical video-based interviews with six elementary teachers experienced in teaching engineering to discuss what they noticed in their students’ thinking and how …


Elementary Teachers’ Reflections On Design Failures And Use Of Fail Words After Teaching Engineering For Two Years, Pamela S. Lottero-Perdue, Elizabeth A. Parry Jun 2017

Elementary Teachers’ Reflections On Design Failures And Use Of Fail Words After Teaching Engineering For Two Years, Pamela S. Lottero-Perdue, Elizabeth A. Parry

Journal of Pre-College Engineering Education Research (J-PEER)

This mixed-methods study examines how teachers who have taught one or two units of the Engineering is Elementary (EiE) curriculum for two years reported on: students’ responses to design failure; the ways in which they, the teachers, supported these students and used fail words (e.g. fail, failure); and the teachers’ broad perspectives and messages to students about failure. In addition, the study explores how strategies, perspectives, messages, and fail word use may change after two years of engineering instruction. This study builds on previous work about elementary teachers’: perspectives on failure prior to teaching engineering, and responses to and perspectives …

The definition was then used to assess curricula, policy documents, teacher practice, and student learning. Through this work, the definition was then used to help with the framing and development of curricula for K-5 classrooms. The resulting curricula are called the PictureSTEM units. These instructional units for K-5 classrooms utilize engineering design and picture books to teach young students …


A Cross-Sectional Study Of Engineering Identity During Undergraduate Education, Allison Godwin, Walter C. Lee Jun 2017

A Cross-Sectional Study Of Engineering Identity During Undergraduate Education, Allison Godwin, Walter C. Lee

School of Engineering Education Faculty Publications

This research paper explores students’ engineering, mathematics, and physics identities across the four years of undergraduate engineering education. The focus of this work are subject-related role identities, or how students position themselves and are positioned by others as the kind of people that engage in engineering, mathematics, or physics. An identity as an engineer is a role identity because it embodies a specific character that an individual plays within a social sphere. In this case, the social sphere is in the process of becoming an engineer. Other research has focused on identity development of engineering students, often either early in …


Formative Assessment To Support Students’ Competences In Inquiry-Based Science Education, Regula Grob, Monika Holmeier, Peter Labudde Jun 2017

Formative Assessment To Support Students’ Competences In Inquiry-Based Science Education, Regula Grob, Monika Holmeier, Peter Labudde

Interdisciplinary Journal of Problem-Based Learning

Inquiry-based education has been part of innovative science teaching for the last few decades. With the competence orientation now underlying many national curricula, one of the emerging questions is how the development of student competences can be fostered in the context of inquiry-based science education. One approach to supporting students in their learning is formative assessment, which is, however, not frequently used in a structured way in daily teaching practice. The aim of this study therefore is to explore what kinds of measures might support science teachers in implementing formative assessment activities in their inquiry-based education. For this, firstly, we …


A Comparison Of Two Equivalent Source Methods For Noise Source Visualization, Tongyang Shi, Yangfan Liu, J Stuart Bolton Jun 2017

A Comparison Of Two Equivalent Source Methods For Noise Source Visualization, Tongyang Shi, Yangfan Liu, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

The various equivalent source methods for noise source visualization can generally be categorized according to two factors: the complexity of the model (order of the sources) and the flexibility of the model (sources at fixed or unfixed location). The models used in the present work comprised: (i) a large number of low-order sources at fixed locations (low model order, low flexibility), and (ii) a high model order series at an unfixed location (high model order, high flexibility). With reference to case (i), a new equivalent source procedure based on a monopole distribution at fixed locations, which is referred to as …


Teaching For Social Justice: (Post-) Model Minority Moments, Candace J. Chow Jun 2017

Teaching For Social Justice: (Post-) Model Minority Moments, Candace J. Chow

Journal of Southeast Asian American Education and Advancement

Much of the literature on model minority discourse focuses on impacts of this stereotype on students. Though the Asian American teacher population is small, it is useful to consider how this stereotype also affects the work of Asian American teachers, their identities, and their pedagogy. This article examines how two Southeast Asian American teachers envision teaching for social justice. Although it appears that these two teachers are products of the model minority stereotype because they have succeeded educationally, a closer examination of their educational pathways reveals that many obstacles, including poverty and a lack of English fluency, could have easily …


Academic Needs And Family Factors In The Education Of Southeast Asian American Students: Dismantling The Model Minority Myth, David M. Lee, Luke Duesbery, Peggy P. Han, Thupten Tashi, Chia S. Her, Valerie Ooka Pang Jun 2017

Academic Needs And Family Factors In The Education Of Southeast Asian American Students: Dismantling The Model Minority Myth, David M. Lee, Luke Duesbery, Peggy P. Han, Thupten Tashi, Chia S. Her, Valerie Ooka Pang

Journal of Southeast Asian American Education and Advancement

The model minority myth is a powerful force in schools. Many teachers believe that Asian American students do not need academic interventions. The purpose of this study was to examine the student achievement of almost a million seventh-grade students from California. The research compared the performance of Southeast Asian Americans, Cambodian, Laotian, and Vietnamese students, on reading and math on the CAT/6 standardized assessment with African American and White American students. Cambodian American and Laotian American students performed significantly lower than their White American peers and compared similarly to their African American peers. Vietnamese American students also scored lower than …


Art History And The Global Challenge: A Critical Perspective, Paula Barreiro López Jun 2017

Art History And The Global Challenge: A Critical Perspective, Paula Barreiro López

Artl@s Bulletin

The challenge of globalization and the “decolonization” of our way of thinking have become a major concern for most art historians. While it is still too early to assess the impact on the discipline of the “Global turn”—a turn that is all the more timid that it materializes more slowly in public collections and public opinions than in books—we nonetheless wanted to probe scholars who are paying close attention to the new practices in global art history. Coming from different cultural milieus and academic traditions, and belonging to different generations, they agreed to answer our questions, and to share with …


Bound To The Mimetic Or The Transformative? Considering Other Possibilities, Jeff Frank Jun 2017

Bound To The Mimetic Or The Transformative? Considering Other Possibilities, Jeff Frank

Education and Culture

Philip Jackson’s “The Mimetic and the Transformative: Alternative Outlooks on Teaching” is widely read both inside and outside of philosophy of education circles and courses, and is best known for sketching out the long-standing difference between the mimetic and transformative traditions in teaching. In this paper, I argue that we need to move beyond the mimetic/transformative divide to a new tradition of teaching. I make the case that Jackson’s understanding of assessment and adaptive education are unduly limiting, and that this keeps his thinking bound to a dualism that needs to be reconstructed. Once reconstructed, new possibilities for philosophers of …


The Philosopher As Parent: John Dewey’S Observations Of His Children’S Language Development And The Development Of His Thinking About Communication, Jeremiah Dyehouse, Krysten Manke Jun 2017

The Philosopher As Parent: John Dewey’S Observations Of His Children’S Language Development And The Development Of His Thinking About Communication, Jeremiah Dyehouse, Krysten Manke

Education and Culture

Can John Dewey’s experiments at the University of Chicago’s Laboratory School teach contemporary inquirers about “learning by making?” This article warrants an affirmative answer to this query. Unlike intellectual historians who trace the source of Dewey’s and his colleagues’ 1890s pedagogies to their cultural biases, we contend that these experiments were substantially conditioned by pragmatic kinds of insights. Specifically, we argue that Dewey’s inquiries into own his children’s language development influenced the development of his early educational experiments as well as his later pragmatic communicative philosophy. On this view, the Laboratory School experiments anticipate Dewey’s later thinking about communication. If …
