Overall, the general consensus among the participants was that an SMS works best if it …


Detangling The Interrelationships Between Self-Regulation And Ill-Structured Problem Solving In Problem-Based Learning, Xun Ge, Victor Law, Kun Huang Oct 2016

Detangling The Interrelationships Between Self-Regulation And Ill-Structured Problem Solving In Problem-Based Learning, Xun Ge, Victor Law, Kun Huang

Interdisciplinary Journal of Problem-Based Learning

One of the goals for problem-based learning (PBL) is to promote self-regulation. Although self-regulation has been studied extensively, its interrelationships with ill-structured problem solving have been unclear. In order to clarify the interrelationships, this article proposes a conceptual framework illustrating the iterative processes among problem-solving stages (i.e., problem representation and solution generation) and self-regulation phases (i.e., planning, execution, and reflection). The dynamics of the interrelationships are further illustrated with three ill-structured problem-solving examples in different domains (i.e., information problem solving, historical inquiry, and science inquiry). The proposed framework contributes to research and practice by providing a new lens to examine …


Using Everyday Objects To Engage Students In Standards Education, Margaret Phillips, Paul Mcpherson Oct 2016

Using Everyday Objects To Engage Students In Standards Education, Margaret Phillips, Paul Mcpherson

Libraries Faculty and Staff Presentations

This paper describes an innovative approach to standards education in an undergraduate mechanical engineering technology design course. The work is focused on making standards appeal to students by using “everyday objects” (e.g. toaster, ladder, grill, etc.) as catalysts to introduce the topic of standards in a way that connects to students’ daily lives. The project involves instructor-librarian collaboration to incorporate information literacy and campus library resources into the standards curricula, so that students not only become familiar with standards resources, but also proficient at searching for and locating the documents. Preliminary results and observations indicate this is an effective approach …


Development Of A Mathematical Model To Estimate Intra-Tumor Oxygen Concentrations Through Multi-Parametric Imaging, Chung-Wein Lee, Keith Stantz, Phd Oct 2016

Development Of A Mathematical Model To Estimate Intra-Tumor Oxygen Concentrations Through Multi-Parametric Imaging, Chung-Wein Lee, Keith Stantz, Phd

School of Health Sciences Faculty Publications

Background

Tumor hypoxia is involved in every stage of solid tumor development: formation, progression, metastasis, and apoptosis. Two types of hypoxia exist in tumors—chronic hypoxia and acute hypoxia. Recent studies indicate that the regional hypoxia kinetics is closely linked to metastasis and therapeutic responses, but regional hypoxia kinetics is hard to measure. We propose a novel approach to determine the local pO2 by fusing the parameters obtained from in vivo functional imaging through the use of a modified multivariate Krogh model.

Methods

To test our idea and its potential to translate into an in vivo setting through the use of …


Control System Research And Development To Support Virtual Prototyping Of Pump And Motors, Rajith Weerasinghe, Monika Ivantysynova, Paul Kalbfleisch Sep 2016

Control System Research And Development To Support Virtual Prototyping Of Pump And Motors, Rajith Weerasinghe, Monika Ivantysynova, Paul Kalbfleisch

The Summer Undergraduate Research Fellowship (SURF) Symposium

Virtual prototyping of positive pumps and motors is incredibly useful, increasing speed of development and lowering cost. The calculations of fluids discharge pressure, displaced by a swashplate-type-axial piston pump/motor is dependent on the load impedance driven by the unit. The load impedance is estimated by a variable orifice found downstream of the unit. Similarly, the suction line impedance is also estimated with an orifice. The current project aims to evaluate the various loading architectures in their ability to quickly and accurately create the desired impedance. The robustness of the loading architectures was tested on a wide range of pump sizes, …


Pushing And Pulling Sara: A Case Study Of The Contrasting Influences Of High School And University Experiences On Engineering Agency, Identity, And Participation, Allison Godwin, Geoff Potvin Sep 2016

Pushing And Pulling Sara: A Case Study Of The Contrasting Influences Of High School And University Experiences On Engineering Agency, Identity, And Participation, Allison Godwin, Geoff Potvin

School of Engineering Education Faculty Publications

This manuscript reports on a longitudinal case study of how one woman, Sara, who had previously considered dropping out of high school authored strong mathematics and science identities and purposefully exhibited agency through her experiences in high school science. These experiences empowered her to choose an engineering major in college; however, her introductory university engineering experiences ultimately pushed her out of engineering. Drawing on critical agency theory, we argue that by paying careful attention to how and why women author their identities and build agency through their experiences in high school, we may gain insight into why women may choose …


Portable Modular Conveyor, Purdue Ect Team Sep 2016

Portable Modular Conveyor, Purdue Ect Team

ECT Fact Sheets Archive

The Portable Modular Conveyor-Material Placer (PMC) is a quick, easy, dependable and cost effective way to place materials in the limits of the confined grade or work area. This specialized piece of equipment was developed to place concrete in front of a concrete slip form-paving machine. The typical method of placing concrete requires a self-propelled belt placer, which is very expensive to purchase and mobilize to the jobsite. The PMC creates a significant cost savings in labor and equipment with the PMC. It is a direct replacement for conventional material placing equipment, including all in grade belt placing machines. As …


Self-Efficacy As A Long-Term Outcome Of A General Education Course On Digital Technologies, Renata A. Revelo, Christopher Schmitz, Duyen Le, Michael C. Loui Aug 2016

Self-Efficacy As A Long-Term Outcome Of A General Education Course On Digital Technologies, Renata A. Revelo, Christopher Schmitz, Duyen Le, Michael C. Loui

School of Engineering Education Faculty Publications

This study investigates the long-term outcomes of a general education course on digital technologies. Through cross-sectional and longitudinal interviews with students, the authors find that self-efficacy is a long-term student outcome. The primary sources of self-efficacy in the course for students were verbal persuasion and mastery experience. Faculty and teaching assistants were key sources for verbal persuasion. Some students experienced a success paradox: they felt successful in the course even though they failed to meet all of their initial expectations. This study can guide faculty in designing a course to promote student self-efficacy.

Generalizing The Quantum Dot Lab Towards Arbitrary Shapes And Compositions, Matthew A. Bliss, Prasad Sarangapani, James Fonseca, Gerhard Klimeck Aug 2016

Generalizing The Quantum Dot Lab Towards Arbitrary Shapes And Compositions, Matthew A. Bliss, Prasad Sarangapani, James Fonseca, Gerhard Klimeck

The Summer Undergraduate Research Fellowship (SURF) Symposium

As applications in nanotechnology reach the scale of countable atoms, computer simulation has become a necessity in the understanding of new devices, such as quantum dots. To understand the various optoelectronic properties of these nanoparticles, the Quantum Dot Lab (QDL) has been created and powered by NEMO5 to simulate on multi-scale, multi-physics bases. QDL is easy to use by offering choices of different QD geometries such as shapes and sizes to the users from a predefined menu. The simplicity of use, however, limits the simulation of general QD shapes and compositions. A method to import generic strained crystalline and amorphous …


Modeling Of A Roll-To-Roll Plasma Cvd System For Graphene, Yudong Chen, Majed A. Alrefae, Anurag Kumar, Timothy S. Fisher Aug 2016

Modeling Of A Roll-To-Roll Plasma Cvd System For Graphene, Yudong Chen, Majed A. Alrefae, Anurag Kumar, Timothy S. Fisher

The Summer Undergraduate Research Fellowship (SURF) Symposium

Graphene is a 2D carbon material that has extraordinary physical properties relevant to many industrial applications such as electronics, oxidation barrier and biosensors. Roll-to-roll plasma chemical vapor deposition (CVD) has been developed to manufacture graphene at large scale. In a plasma CVD chamber, graphene is grown on a copper foil as it passes through a high-temperature plasma region. The temperatures of the gas and the copper foil play important roles in the growth of graphene. Consequently, there is a need to understand the temperature and gas velocity distributions in the system. The heat generated in the plasma creates a thermal …
