Stand And Deliver: An Epistemologically-Driven Perspective Of College Lecture, Bonnie Bost Laster, Matthew Davis

Perspectives In Learning

Current pedagogical trends reveal lecture is steadily losing favor as contemporary techniques (e.g., constructivist, experiential, and flipped) gain popularity in higher education. While these techniques have merit and evidence for their use is compelling, we contend that lecture need not be abandoned entirely. With support from personal epistemological theories, as well as research on student preference, we purport that there is still a place for lecture in the modern academy. We consider students’ personal epistemological maturation during the college years; namely, the ways in which students view and construct their knowledge and beliefs. We posit that active lecture may be …

Characterization Of Edge Damage Induced On Rebco Superconducting Tape By Mechanical Slitting, William N. Hartnett, Javier Ramirez, Tanner E.R. Olson, Christopher T. Hopp, Matthew C. Jewell, Allan R. Knoll, Drew W. Hazelton, Yifei Zhang, T. Olsen

Michigan Tech Publications, Part 1

Rare-earth barium-copper-oxide (REBCO) superconductors are high-field superconductors fabricated in a tape geometry that can be utilized in magnet applications well in excess of 20 T. Due to the multilayer architecture of the tape, delamination is one cause of mechanical failure in REBCO tapes. During a mechanical slitting step in the manufacturing process, edge cracks can be introduced into the tape. These cracks are thought to be potential initiation sites for crack propagation in the tapes when subjected to stresses in the fabrication and operation of magnet systems. We sought to understand which layers were the mechanically weakest by locating the …

Fundamental Aspects Of The Interaction Between Light And Nanostructures, Stephen Keith Sanders

Physics & Astronomy ETDs

Recent breakthroughs in nanophotonics have brought new opportunities to control and manipulate light at the nanoscale. The optical properties of metallic nanostructures have attracted particular interest because of their plasmon resonances, which couple strongly with visible light, and generate large near-field enhancements in their vicinity. In the first part of this thesis, we investigate the fundamental limits of the local density of photonic states near nanostructures by analyzing a sum rule relating its spectral integral to the field induced by a static dipole. Next, we analyze how the design of metallic nanoantennas can benefit from incorporating active materials that display …

Talented, Yet Seen With Suspicion: Surveillance Of International Students And Scholars In The United States, Ryan M. Allen, Krishna Bista

Education Faculty Articles and Research

The attacks of September 11, 2001, put terrorism at the forefront of the American political landscape. Donald Trump played into these fears of terrorism through his political rhetoric during his presidency, particularly targeting international students as “threats” to the nation. However, we argue that the labeling of international students as security threats was not started after 9/11 nor invented by Trump. Through historical records and accounts across decades of policies related to this issue, we seek to answer two questions: How has the U.S. government monitored visa policies and programs for international students? How have U.S. national policies evolved to …

Physicochemical And Microstructural Characterization Of Whey Protein Films Formed With Oxidized Ferulic/Tannic Acids, Yaosong Wang, Youling L. Xiong

Animal and Food Sciences Faculty Publications

Protein-based biodegradable packaging films are of environmental significance. The effect of oxidized ferulic acid (OFA)/tannic acid (OTA) on the crosslinking and film-forming properties of whey protein isolate (WPI) was investigated. Both of the oxidized acids induced protein oxidation and promoted WPI crosslinking through the actions of quinone carbonyl and protein sulfhydryl, and amino groups. OTA enhanced the tensile strength (from 4.5 MPa to max 6.7 MPa) and stiffness (from 215 MPa to max 376 MPa) of the WPI film, whereas OFA significantly increased the elongation at break. The water absorption capability and heat resistance of the films were greatly improved …

Articles

We propose a methodological framework to support the development of personalized courses that improve patients’ understanding of their condition and prescribed treatment. Inspired by Intelligent Tutoring Systems (ITSs), the framework uses an eLearning ontology to express domain and learner models and to create a course. We combine the ontology with a procedural reasoning approach and precompiled plans to operationalize a design across disease conditions. The resulting courses generated by the framework are personalized across four patient axes—condition and treatment, comprehension level, learning style based on the VARK (Visual, Aural, Read/write, Kinesthetic) presentation model, and the level of understanding of specific …
