632	Traditional Versus Nontraditional Instructional and Assessment Differences in 8th-Grade History-Social Science Achievement Landers, John David 01 January 2018 (has links) In southern California school districts, 8th grade students in history-social science (H-SS) classes did not perform well on the California Standards Test (CST). To improve student performance, middle school H-SS teachers in some districts received staff development in the use of authentic assessment, the understanding and application of multiple intelligences theory, and the application of a student centered focus in lesson design and instruction. The purpose of this comparative pretest/posttest study was to determine if there was significant achievement difference between 2 8th-grade U.S. H-SS classes taught in 2 districts. The research question addressed a significant difference in CST H-SS achievement scores between 8th-grade students taught using multiple intelligences strategies and authentic assessments (n = 28) and those who were taught using traditional strategies and curriculum assessments (n = 31). The theoretical foundation for this study was constructivism. Post-data from archived student scores on the CST H-SS test were collected and analyzed using an analysis of covariance (ANCOVA), controlling for varying differences in CST pre-test H-SS scores. There was a statistically significant difference in posttest CST H-SS scores between the 2 groups (F = 10.491, p < .002), with the nontraditional group scoring higher. Based on the findings, it is recommended that district leaders provide professional development opportunities for teachers in nontraditional constructivist instructional strategies that support student-centered instruction. These endeavors may lead to positive social change if H-SS teachers change instruction and assessment methods to improve student achievement, thus, meeting graduation requirements and enhancing citizenship development.

633	Computational Interdisciplinarity: A Study in the History of Science January 2019 (has links) abstract: This dissertation focuses on creating a pluralistic approach to understanding and measuring interdisciplinarity at various scales to further the study of the evolution of knowledge and innovation. Interdisciplinarity is considered an important research component and is closely linked to higher rates of innovation. If the goal is to create more innovative research, we must understand how interdisciplinarity operates. I begin by examining interdisciplinarity with a small scope, the research university. This study uses metadata to create co-authorship networks and examine how a change in university policies to increase interdisciplinarity can be successful. The New American University Initiative (NAUI) at Arizona State University (ASU) set forth the goal of making ASU a world hub for interdisciplinary research. This kind of interdisciplinarity is produced from a deliberate, engineered, reorganization of the individuals within the university and the knowledge they contain. By using a set of social network analysis measurements, I created an algorithm to measure the changes to the co-authorship networks that resulted from increased university support for interdisciplinary research. The second case study increases the scope of interdisciplinarity from individual universities to a single scientific discourse, the Anthropocene. The idea of the Anthropocene began as an idea about the need for a new geological epoch and underwent unsupervised interdisciplinary expansion due to climate change integrating itself into the core of the discourse. In contrast to the NAUI which was specifically engineered to increase interdisciplinarity, the I use keyword co-occurrence networks to measure how the Anthropocene discourse increases its interdisciplinarity through unsupervised expansion after climate change becomes a core keyword within the network and behaves as an anchor point for new disciplines to connect and join the discourse. The scope of interdisciplinarity increases again with the final case study about the field of evolutionary medicine. Evolutionary medicine is a case of engineered interdisciplinary integration between evolutionary biology and medicine. The primary goal of evolutionary medicine is to better understand "why we get sick" through the lens of evolutionary biology. This makes it an excellent candidate to understand large-scale interdisciplinarity. I show through multiple type of networks and metadata analyses that evolutionary medicine successfully integrates the concepts of evolutionary biology into medicine. By increasing our knowledge of interdisciplinarity at various scales and how it behaves in different initial conditions, we are better able to understand the elusive nature of innovation. Interdisciplinary can mean different things depending on how its defined. I show that a pluralistic approach to defining and measuring interdisciplinarity is not only appropriate but necessary if our goal is to increase interdisciplinarity, the frequency of innovations, and our understanding of the evolution of knowledge. / Dissertation/Thesis / Doctoral Dissertation Biology 2019 History Linguistics Computer science Computational History of Science Computational Linguistics Graph Theory Interdisciplinarity Network Theory Social Network Analysis

635	Heavy Metal in Medieval Europe Klimmek, Sean M 21 March 2022 (has links) How and why did plate armor come to be widely used in Medieval Europe? I trace the historical development of armor in Europe from antiquity to the middle ages, and then identify the main causes that pushed European warriors to develop and adopt plate armor from the 14th to the 16th centuries. I rely on prior research by scholars and historians of arms and armor, as well as primary source documents that describe arms and armor and their use in tournaments and on the battlefield. I conclude that a combination of social, political, military, and technical factors pushed European warriors to adopt plate armor. I also briefly discuss the demise of plate armor due to increasing use of firearms in the 16th century and the growth of professional armies.

637	THE CONSTRUCTION OF MODERN TIMEKEEPING IN THE ANGLO-AMERICAN WORLD, 1876-1913 Johnston, Scott 11 1900 (has links) This dissertation asks why the system of time measurement set up towards the end of the nineteenth century took the form that it did. The answer is partially dependant on the advent of new technologies such as railways, steamships, and telegraphs. However, instead of focusing on a teleological story of technological progress, this dissertation derives its answer by examining the social, political, and cultural context of the individuals involved. The dissertation uses the 1884 International Meridian Conference as a case study to suggest that time reform was driven by professional context more than by technological imperatives or national interest. Astronomers and engineers came to the conference with very different visions for modern timekeeping. Using a constructivist lens, this dissertation examines the decision-laden process by which temporal knowledge was constructed. Questions about the very nature of accurate time was at the heart of the debate: was time a public good, a commodity, or a specialized tool? The answers to these questions depended heavily on one’s profession, and as a result the conference, directed by astronomers who preferred time as a specialized tool, rejected standard time as a broad reformation of civil timekeeping for the public. The process of construction continued after the conference as well, as the universality of standard time became wrapped up with the heightened accuracy required by specialized astronomical time. Entrepreneurs latched on to this, selling accurate time as a desirable symbol of modernity, while at the same time large numbers of people continued to use older timekeeping methods that were more convenient. New timekeeping methods did not sweep aside the old, leaving timekeeping a more complex, rather than a simplified, process. The standard time system which emerged from this complexity was far from inevitable, and in fact remained largely incomplete. / Thesis / Doctor of Philosophy (PhD) / This dissertation asks why the system of time measurement set up towards the end of the nineteenth century took the form that it did. While partially dependent on new technologies such as railways and telegraphs, timekeeping was shaped more directly by the cultural context of the individuals involved. The dissertation uses the 1884 International Meridian Conference as a case study to suggest that time reform was driven by professional norms more than by national interest or changes in technology. Astronomers and engineers came to the conference with very different visions for modern timekeeping. Indeed, questions about the very nature of accurate time was at the heart of the debate: was time a public good, a commodity, or a specialized tool?

Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash. Finally, I examine the difficulty of talking about boundaries of various kinds, such as temporal, spatial and functional.

640	Pythagoras at the smithy : science and rhetoric from antiquity to the early modern period Tang, Andy chi-chung 07 November 2014 (has links) It has been said that Pythagoras discovered the perfect musical intervals by chance when he heard sounds of hammers striking an anvil at a nearby smithy. The sounds corresponded to the same intervals Pythagoras had been studying. He experimented with various instruments and apparatus to confirm what he heard. Math, and in particular, numbers are connected to music, he concluded. The discovery of musical intervals and the icon of the musical blacksmith have been familiar tropes in history, referenced in literary, musical, and visual arts. Countless authors since Antiquity have written about the story of the discovery, most often found in theoretical texts about music. However, modern scholarship has judged the narrative as a myth and a fabrication. Its refutation of the story is peculiar because modern scholarship has failed to disprove the nature of Pythagoras’s discovery with valid physical explanations. This report examines the structural elements of the story and traces its evolution since Antiquity to the early modern period to explain how an author interprets the narrative and why modern scholarship has deemed it a legend. The case studies of Nicomachus of Gerasa, Claudius Ptolemy, Boethius, and Marin Mersenne reveal not only how the story about Pythagoras’s discovery functions for each author, but also how the alterations in each version uncover an author’s views on music. / text History of music theory Pythagoras Hammers Anvil Nicomachus Claudius Ptolemy Boethius Marin Mersenne Reception history Ancient music Pythagoreanism Acoustics History of science Music history
