Examining Science Learning And Attitude By At-Risk Students After They Used A Multimedia-Enriched Problem-Based Learning Environment, Min Liu, Sa Liu, Zilong Pan, Wenting Zou, Chenglu Li

Interdisciplinary Journal of Problem-Based Learning

Most of the previous problem-based learning (PBL) studies have been conducted with gifted or regular education students and have shown successes. However, little research on PBL exists for disadvantaged middle school students, especially students who are considered to be at risk of failing academically. In this study, we examined the use of a multimedia-enriched PBL science environment by at-risk middle school students. The results, using a mixed-methods design, showed that these students significantly improved their science knowledge and attitude toward science after they engaged in PBL learning. While there were no differences in the scores between the genders, the gain …

Developing Clinical Reasoning Skills Through Argumentation With The Concept Map Method In Medical Problem-Based Learning, Jihyun Si, Hyun-Hee Kong, Sang-Hwa Lee

Interdisciplinary Journal of Problem-Based Learning

This study aims to explore the effects of argumentation with the concept map method during medical problem-based learning (PBL) on individual clinical reasoning. Individual clinical reasoning ability was assessed through problem-solving performance and arguments that students constructed during individual clinical reasoning processes. Toulmin’s model of argument was utilized as a structure for arguments. The study also explored whether there would be any differences between the firstand second-year medical students. Ninety-five medical students participated in this study, and they took two PBL modules. During PBL, they were asked as a group to construct concept maps based on their argumentation about a …

An Interdisciplinary Discourse Between Dewey And Self-Determination Theory: Motivation In The Wake Of Monetizing Education, Jacqueline A. Goldman, Benjamin C. Heddy, Susan Laird

Education and Culture

The purpose of this theoretical exposition is to bring two fields into discussion concerning the issue of motivation, in the new monetized context of education, through an encounter between John Dewey and self-determination theory. Using Dewey's Experience and Education as well as self-determination theory's most fundamental scholarship (e.g., Ryan and Deci 2000), we offer a contemporary parallel with Dewey's thoughts on "New" and "Old" education and examine it through the lens of self-determination theory. This interdisciplinary perspective combines educational psychology with philosophy of education to retheorize motivation as a critical response to the "New" educational shift toward monetization, which we …

What’S The Use Of Conflict In Dewey? Toward A Pedagogy Of Compromise, Christophe Point

Education and Culture

In this article, we argue for the importance of the notion of conflict in John Dewey's philosophy. Indeed, many criticisms have been leveled against Dewey regarding his political philosophy and his philosophy of education based on the idea that he underestimated the conflict inherent in human affairs. These criticisms are compelling because they link the two sides—educational and political—of Dewey's philosophy. Critics simultaneously address their criticisms to one side vis-à-vis the adverse consequences caused as a result of the other side. In response to this analysis, we want to argue that conflict is indispensable for understanding the theory of inquiry …

Progressive Education And Racial Justice: Examining The Work Of John Dewey, Kelly Vaughan

Education and Culture

John Dewey was a progressive theorist, a pragmatist, a philosopher, and arguably the most influential American educator of the twentieth century. Yet, despite extensive documentation about John Dewey's philosophies of education and democracy, there is limited research and no consensus about Dewey's views about race and racism. I use a combination of primary sources, secondary sources, and archival data to explore the John Dewey's ideas about progressivism, racism, and schooling. I assert that Dewey, despite an expressed commitment to full and equal rights for African American students, normalized the experience of White students and implicitly endorsed accommodationist education reforms for …

Creative Integration And Pragmatist Optimism: Dispositions For “The Task Before Us”, Barbara S. Stengel

Education and Culture

How can and will educators in any setting work with young people of all ages to enable them to develop the ability to interrogate—without denigrating—the claims of candidates, the newsmaking of media, the needs of their neighbors, and the fears of their family members? The answer I offer and defend here involves two dispositions—creative integration and pragmatist optimism—that I view as critical to the pursuit of vibrant and viable political democracy. These dispositions are, I argue, necessary to and evidence of the very possibility of a polity worthy of the "democratic" label.

Knowledge Can Be Mightier Than The Gun, César E. Becerra

Education and Culture

The following work is intended to be a closer look and commentary on the issue of gun violence and mass shootings in the United States of America. An overarching pragmatic lens will be utilized to argue that the time is now to make a change in our current trajectory of normalized gun violence in our schools, and society in general. We currently need to bring the controversial and difficult topic of gun violence and mass shootings into our classrooms, have open dialogue, and begin to purposely educate students about the subject on a real and deeper level than just the …

Visualizing Near-Wall Two-Phase Flow Morphology During Confined And Submerged Jet Impingement Boiling To The Point Of Critical Heat Flux, C. Mira Hernandez, J. A. Weibel, S. V. Garimella

CTRC Research Publications

Confined and submerged two-phase jet impingement is a compact, low-pressure-drop solution for high heat flux dissipation from electronic components. Nucleate boiling can be sustained up to significantly higher heat fluxes during two-phase jet impingement as compared to pool boiling. The increases in critical heat flux are explained via hydrodynamic mechanisms that have been debated in the literature. In this study, the two-phase flow morphology of a single subcooled jet of water that impinges on a circular heat source is visualized at high speed with synchronized top and side views of the confinement gap. The impinging jet issues from a 3.75-mm-diameter …

A Permeable-Membrane Microchannel Heat Sink Made By Additive Manufacturing, I. L. Collins, J. A. Weibel, L. Pan, S V. Garimella

CTRC Research Publications

Microchannel heat sinks are capable of removing dense heat loads from high-power electronic devices with low thermal resistance, but suffer from high pressure drops due to the small channel dimensions. Features that reduce the pressure drop, such as manifolds, increase fabrication complexity and are constrained by traditional subtractive manufacturing approaches. Additive manufacturing technologies offer improved design freedom and reduced geometric restrictions, expanding the types of features that can be produced and integrated into a heat sink. In this work, a novel permeable membrane microchannel (PMM) heat sink geometry is proposed and fabricated using direct metal laser sintering (DMLS) of an …

Design, Fabrication, And Characterization Of A Compact Hierarchical Manifold Microchannel Heat Sink Array For Two-Phase Cooling, D. Back, K. P. Drummond, M. D. Sinanis, J. A. Weibel, S V. Garimella, D. Peroulis, D. B. Janes

CTRC Research Publications

High-heat-flux removal is critical for the nextgeneration electronic devices to reliably operate within their temperature limits. A large portion of the thermal resistance in a traditional chip package is caused by thermal resistances at interfaces between the device, heat spreaders, and the heat sink; embedding the heat sink directly into the heat-generating device can eliminate these interface resistances and drastically reduce the overall thermal resistance. Microfluidic cooling within the embedded heat sink improves the heat dissipation, with two-phase operation offering the potential for dissipation of very high heat fluxes while maintaining moderate chip temperatures. To enable multichip stacking and other …

A Coupled Wicking And Evaporation Model For Prediction Of Pool Boiling Critical Heat Flux On Structured Surfaces, H. Hu, J. A. Weibel, S V. Garimella

CTRC Research Publications

Boiling is an effective heat transfer mechanism that is central to a variety of industrial processes including electronic systems, power plants, and nuclear reactors. Micro-/nano-structured surfaces have been demonstrated to significantly enhance the critical heat flux (CHF) during pool boiling, but there is no consensus on how to predict the structure-induced CHF enhancement. In this study, we develop an analytical model that takes into consideration key mechanisms that govern CHF during pool boiling on structured surfaces, namely, capillary wicking and evaporation of the liquid layer underneath the bubble. The model extends existing wicking-based CHF theories by introducing the competing evaporation …

Evaporation-Driven Micromixing In Sessile Droplets For Miniaturized Absorbance-Based Colorimetry, A. Chandramohan, M. Chakraborty, J. A. Weibel, S V. Garimella

CTRC Research Publications

We demonstrate the use of an evaporating, sessile droplet on a nonwetting substrate as a miniature micromixing device to conduct sample−dye reactions for absorbance-based colorimetry. The nonwetting substrate supports buoyancy-induced mixing inside the droplet for rapid completion of the measurement. The Bradford assay is used as a proof of concept, where a protein-containing sample is reacted with a reagent dye to measure the protein concentration. Viability of absorbance measurement through the droplet is first established using droplets in which the reactants are mixed prior to their deposition onto the substrate. In a second set of experiments involving in situ mixing, …

Design Of An Area-Scalable Two-Layer Evaporator Wick For High-Heat-Flux Vapor Chambers, S. Sudhakar, J. A. Weibel, S V. Garimella

CTRC Research Publications

A hybrid two-layer evaporator wick is proposed for passive, high-heat-flux dissipation over large areas using a vapor chamber heat spreader. For such applications, the evaporator wick layer must be designed to simultaneously minimize the device temperature rise and minimize the flow resistance to capillary feeding of the wick. This requires a strategy that exploits the benefits of a thin wick for reduced thermal resistance and a thick wick for liquid feeding. In the present design, a thick cap layer of wick material evenly routes liquid to a thin, low-thermal-resistance base layer through an array of vertical liquid-feeding posts. This two-layer …

The Petal Effect Of Parahydrophobic Surfaces Offers Low Receding Contact Angles That Promote Effective Boiling, T. P. Allred, J. A. Weibel, S V. Garimella

CTRC Research Publications

Despite extensive study of boiling processes and their widespread use in industry, critical interactions between the fluid and surface during boiling remain poorly understood. Simplistic, static descriptions of the contact angle are still relied upon to describe the effects of surface wettability on dynamic interfacial processes that govern boiling. This work demonstrates the critical role of the dynamic wettability characteristics of a surface on bubble growth dynamics and boiling performance. In spite of their superior nucleation behavior, hydrophobic surfaces have received little attention for boiling applications due to their typically premature transition from efficient nucleate boiling to inefficient film boiling. …

Evaluation Of Additively Manufactured Microchannel Heat Sinks, I. L. Collins, J. A. Weibel, L. Pan, S V. Garimella

CTRC Research Publications

Microchannel heat sinks allow removal of dense heat loads from high-power electronic devices at modest chip temperature rises. Such heat sinks are produced primarily using conventional subtractive machining techniques or anisotropic chemical etching, which restricts the geometric features that can be produced. Owing to their layer-by-layer and direct-write approaches, additive manufacturing (AM) technologies enable more design-driven construction flexibility and offer improved geometric freedom. Various AM processes and materials are available, but their capability to produce features desirable for microchannel heat sinks has received limited assessment. Following a survey of commercially mature AM techniques, direct metal laser sintering (DMLS) was used …

Identification Of Nucleate Boiling As The Dominant Heat Transfer Mechanism During Confined Two-Phase Jet Impingement, M. D. Clark, J. A. Weibel, S V. Garimella

CTRC Research Publications

Thermal management of high-power electronics requires cooling strategies capable of dissipating high heat fluxes while maintaining the device at low operating temperatures. Two-phase jet impingement offers a compact cooling technology capable of meeting these requirements at a low pressure drop. Generally, confined impingement geometries are used in electronics cooling applications, where the flow is constrained between the hot surface and orifice plate. Understanding the primary heat transfer mechanisms occurring as boiling takes place on the surface during jet impingement is important, specifically under such confined conditions. In this study, heat transfer from a copper surface is experimentally characterized in both …

Experimental Investigation Of Boiling Regimes In A Capillary-Fed Two-Layer Evaporator Wick, S. Sudhakar, J A. Weibel, S V. Garimella

CTRC Research Publications

Vapor chambers with transformative evaporator wick designs capable of passively dissipating high heat fluxes over large areas, while maintaining low thermal resistances, can meet the thermal management needs of next-generation power semiconductor devices. Our prior work proposed a two-layer evaporator wick structure to enhance the performance of vapor chambers operating at high heat fluxes. The current study experimentally characterizes the capillary-fed boiling heat transfer behavior in such a two-layer evaporator wick, compared to a homogeneous (single-layer) wick, over a 1 cm2 evaporator area. The two-layer design comprises a thin base wick layer that is fed with liquid from a thick …

Zucchini Cultivar Evaluation For Production In West-Central Indiana, 2018, Petrus Langenhoven

Midwest Vegetable Trial Reports

The state of Indiana is not known nationally as a major zucchini producing state. However, small farm operators produce zucchini generally for local farmers markets, restaurants and some retail outlets. Gowers always wants to know which variety is most suitable for their farming location and market. There are a plethora of varieties available that have different fruit types and growth habits. Characteristics like potential yield and disease resistance are always very important considerations for growers. This paper reports on ten zucchini entries (Table 1; Fig. 3-12) that were evaluated at the Throckmorton Purdue Agriculture Center/Meigs Horticulture Facility, Lafayette, Indiana.
