Early Childhood Science And Engineering: Engaging Platforms For Fostering Domain-General Learning Skills, Andres S. Bustamante, Daryl B. Greenfield, Irena Nayfeld

ETSU Faculty Works

Early childhood science and engineering education offer a prime context to foster approaches-to-learning (ATL) and executive functioning (EF) by eliciting children’s natural curiosity about the world, providing a unique opportunity to engage children in hands-on learning experiences that promote critical thinking, problem solving, collaboration, persistence, and other adaptive domain-general learning skills. Indeed, in any science experiment or engineering problem, children make observations, engage in collaborative conversations with teachers and peers, and think flexibly to come up with predictions or potential solutions to their problem. Inherent to science and engineering is the idea that one learns from initial failures within an …

A Perceptual Comparison Of “Black Box” Modeling Algorithms For Nonlinear Audio Systems, Paul G. Mayo

Student Theses

Nonlinear systems identification is a widespread topic of interest, particularly within the audio industry, as these techniques are employed to synthesize black box models of nonlinear audio effects. Given the myriad approaches to black box modeling, questions arise as to whether an “optimal” approach exists, or one that achieves valid subjective results as a model with minimal computational expense. This thesis uses ABX listening tests to compare black box models of three hardware audio effects using two popular nonlinear implementations, along with two proposed modified implementations. Models were constructed in the Hammerstein form using sine sweeps and a novel measurement …

Opto-Thermal Characterization Of Plasmon And Coupled Lattice Resonances In 2-D Metamaterial Arrays, Vinith Bejugam

Graduate Theses and Dissertations

Growing population and climate change inevitably requires longstanding dependency on sustainable sources of energy that are conducive to ecological balance, economies of scale and reduction of waste heat. Plasmonic-photonic systems are at the forefront of offering a promising path towards efficient light harvesting for enhanced optoelectronics, sensing, and chemical separations. Two-dimensional (2-D) metamaterial arrays of plasmonic nanoparticles arranged in polymer lattices developed herein support thermoplasmonic heating at off-resonances (near infrared, NIR) in addition to regular plasmonic resonances (visible), which extends their applicability compared to random dispersions. Especially, thermal responses of 2-D arrays at coupled lattice resonance (CLR) wavelengths were comparable …

Engineering Is Elementary: Identifying Instances Of Collaboration During The Engineering Design Process, Lora Kulakowski Gruber-Hine

Dissertations - ALL

21st century educational reform initiatives value creativity, collaboration, innovation, and higher-order thinking (Scardamalia, 2002), the skills needed for students to successfully address the complex engineering challenges facing society. A Framework for K-12 Science Education: Practice, Crosscutting Concepts and Core Ideas (NRC, 2012) acknowledges that advances in knowledge occur through collaboration, with many minds working together to communicate and share ideas over time. It has been proposed that collaboration, creativity, and persistence are of value to engineering (Cunningham, 2012), and that engineering possesses a unique set of epistemic practices, including envisioning multiple solutions and teamwork (Cunningham and Kelly, 2017). Cunningham (2012) …

College Readiness, Student Expectations And Sucess: The Role Of Non-Cognitive Skills, Malachi Nichols, Julie R. Trivitt, Gema Zamarro

Education Reform Faculty and Graduate Students Publications

Attending college is a significant human capital investment but only about 56% of those who start college will have a completed degree 6 years later. This makes identifying which skills are associated with college success an important policy concern. We surveyed over 1,100 entering college freshmen, majoring in business and engineering at a public university in the US, and combined this information with administrative data to create a comprehensive data set that, in addition to the usual academic performance data, cognitive ability measures, and demographics, also included measures of non-cognitive skills, personality traits, and student expectations about college success.

The Perceived Mentoring Experiences Of Male And Female Doctoral Students In Sociology, Macsu A. Hill

Seton Hall University Dissertations and Theses (ETDs)

Over the years, women have made significant strides in the science, technology, engineering, and mathematics (STEM) fields. Nevertheless, women continue to be underrepresented at the graduate and academic career entry levels, and minority women continue to lag behind Whites in navigating the pipeline to an academic career in the STEM disciplines. In sociology for instance, women overall are well represented at the BA level, but experience a steep decline when moving to doctoral education and then into subsequent academic careers. Numerous explanations have been advanced by educators and researchers to explain the dearth of underrepresented minority (URM) female doctoral students. …
