Lost in the archive: vision, artefact and loss in the evolution of hypertext

How does one write the history of a technical machine? Can we say that technical machines have their own genealogies, their own evolutionary dynamic? The technical artefact constitutes a series of objects, a lineage or a line. At a cursory level, we can see this in the fact that technical machines come in generations - they adapt and adopt characteristics over time, one suppressing the other as it becomes obsolete. It is argued that technics has its own evolutionary dynamic, and that this dynamic stems neither from biology nor from human societies. Yet 'it is impossible to deny the role of human thought in the creation of technical artefacts' (Guattari 1995, p. 37). Stones do not automatically rise up into a wall - humans 'invent' technical objects. This, then, raises the question of technical memory. Is it humans that remember previous generations of machines and transfer their characteristics to new machines? If so, how and where do they remember them? It is suggested that humans learn techniques from technical artefacts, and transfer these between machines. This theory of technical evolution is then used to understand the genealogy of hypertext. The historical differentiations of hypertext in different technical systems is traced. Hypertext is defined as both a technical artefact and also a set of techniques: both are a part of this third milieu, technics. The difference between technical artefact and technical vision is highlighted, and it is suggested that technique and vision change when they are externalised as material artefact. The primary technique traced is association, the organisational principle behind the hypertext systems explored in the manuscript. In conclusion, invention is shown to be an act of exhumation, the transfer and retroactiviation of techniques from the past. This thesis presents an argument for a new model of technical evolution, a model which claims that technics constitutes its own dynamic, and that this dynamic exceeds human evolution. It traces the genealogy of hypertext as a set of techniques and as series of material artefacts. To create this geneaology I draw on interviews conducted with Douglas Engelbart, Ted Nelson and Andries van Dam, as well as a wide variety of primary and secondary resources

The Effect of Aleks on Students\u27 Mathematics Achievement in an Online Learning Environment and the Cognitive Complexity of the Initial and Final Assessments

For many courses, mathematics included, there is an associated interactive e-learning system that provides assessment and tutoring. Some of these systems are classified as Intelligent Tutoring Systems. MyMathLab, Mathzone, and Assessment of LEarning in Knowledge Space (ALEKS) are just a few of the interactive e-learning systems in mathematics. In ALEKS, assessment and tutoring are based on the Knowledge Space Theory. Previous studies in a traditional learning environment have shown ALEKS users to perform equally or better in mathematics achievement than the group who did not use ALEKS. The purpose of this research was to investigate the effect of ALEKS on students’ achievement in mathematics in an online learning environment and to determine the cognitive complexity of mathematical tasks enacted by ALEKS’s initial (pretest) and final (posttest) assessments. The targeted population for this study was undergraduate students in College Mathematics I, in an online course at a private university in the southwestern United States. The study used a quasi-experimental One-Group non-randomized pretest and posttest design. Five methods of analysis and one model were used in analyzing data: t-test, correctional analysis, simple and multiple regression analysis, Cronbach’s Alpha reliability test and Webb’s depth of knowledge model. A t-test showed a difference between the pretest and posttest reports, meaning ALEKS had a significant effect on students’ mathematics achievement. The correlation analysis showed a significant positive linear relationship between the concept mastery reports and the formative and summative assessments reports meaning there is a direct relationship between the ALEKS concept mastery and the assessments. The regression equation showed a better model for predicting mathematics achievement with ALEKS when the time spent learning in ALEKS and the concept mastery scores are used as part of the model. According to Webb’s depth of knowledge model, the cognitive complexity of the pretest and posttest question items used by ALEKS were as follows: 50.5% required application of skills and concepts, 37.1% required recall of information, and 12.4% required strategic thinking: None of the questions items required extended thinking or complex reasoning, implying ALEKS is appropriate for skills and concepts building at this level of mathematics

Hypertext Semiotics in the Commercialized Internet

Die Hypertext Theorie verwendet die selbe Terminologie, welche seit Jahrzehnten in der semiotischen Forschung untersucht wird, wie z.B. Zeichen, Text, Kommunikation, Code, Metapher, Paradigma, Syntax, usw. Aufbauend auf jenen Ergebnissen, welche in der Anwendung semiotischer Prinzipien und Methoden auf die Informatik erfolgreich waren, wie etwa Computer Semiotics, Computational Semiotics und Semiotic Interface Engineering, legt diese Dissertation einen systematischen Ansatz für all jene Forscher dar, die bereit sind, Hypertext aus einer semiotischen Perspektive zu betrachten. Durch die Verknüpfung existierender Hypertext-Modelle mit den Resultaten aus der Semiotik auf allen Sinnesebenen der textuellen, auditiven, visuellen, taktilen und geruchlichen Wahrnehmung skizziert der Autor Prolegomena einer Hypertext-Semiotik-Theorie, anstatt ein völlig neues Hypertext-Modell zu präsentieren. Eine Einführung in die Geschichte der Hypertexte, von ihrer Vorgeschichte bis zum heutigen Entwicklungsstand und den gegenwärtigen Entwicklungen im kommerzialisierten World Wide Web bilden den Rahmen für diesen Ansatz, welcher als Fundierung des Brückenschlages zwischen Mediensemiotik und Computer-Semiotik angesehen werden darf. Während Computer-Semiotiker wissen, dass der Computer eine semiotische Maschine ist und Experten der künstlichen Intelligenz-Forschung die Rolle der Semiotik in der Entwicklung der nächsten Hypertext-Generation betonen, bedient sich diese Arbeit einer breiteren methodologischen Basis. Dementsprechend reichen die Teilgebiete von Hypertextanwendungen, -paradigmen, und -strukturen, über Navigation, Web Design und Web Augmentation zu einem interdisziplinären Spektrum detaillierter Analysen, z.B. des Zeigeinstrumentes der Web Browser, des Klammeraffen-Zeichens und der sogenannten Emoticons. Die Bezeichnung ''Icon'' wird als unpassender Name für jene Bildchen, welche von der graphischen Benutzeroberfläche her bekannt sind und in Hypertexten eingesetzt werden, zurückgewiesen und diese Bildchen durch eine neue Generation mächtiger Graphic Link Markers ersetzt. Diese Ergebnisse werden im Kontext der Kommerzialisierung des Internet betrachtet. Neben der Identifizierung der Hauptprobleme des eCommerce aus der Perspektive der Hypertext Semiotik, widmet sich der Autor den Informationsgütern und den derzeitigen Hindernissen für die New Economy, wie etwa der restriktiven Gesetzeslage in Sachen Copyright und Intellectual Property. Diese anachronistischen Beschränkungen basieren auf der problematischen Annahme, dass auch der Informationswert durch die Knappheit bestimmt wird. Eine semiotische Analyse der iMarketing Techniken, wie z.B. Banner Werbung, Keywords und Link Injektion, sowie Exkurse über den Browser Krieg und den Toywar runden die Dissertation ab

Memory-craft: The Role Of Domestic Technology In Women\u27s Journals

The term memory-craft refers to arts and crafts media where personal memorabilia and journaling are combined and assembled into book form. Examples of memory-crafts include scrapbooks, art journals, and altered books. Traditionally, women have been the primary assemblers of memory-crafts, using this form as a method of autobiography and genealogical archiving. Memory-crafting is often associated with the amateur home-crafter, and while historians have long understood its cultural significance, academia has not properly considered memory-craft as a type of alternative discourse. The purpose of this study is to examine the use of memory-crafting as a non-traditional method of writing, especially among women who use it to record personal and familial narratives. Just as women are usually the primary care-takers of the family, through memory-craft they also become responsible for collecting and preserving memories, which would otherwise become lost. These memories of the everyday--birthday parties, family vacations, and wedding anniversaries--grow to be culturally significant over time. Through the use of domestic technology, which today includes both paper scraps and home computer systems, memory-crafts assist in the interpretation of the present and provide insight into the past. To help explore the connection between domestic technology and memory-crafts, I have organized this study into four themes: history and memory-craft; women and domestic technology; feminist literary autobiography and memoir; and feminism and hypermedia. My approach is a mixture of fictionalized personal narrative and analysis loosely modeled after Writing Machines by N. Katherine Halyes and Alias Olympia by Eunice Lipton. Just as I discuss experimental methods of writing in the form of memory-crafting, I also use an experimental writing technique which gathers from personal memories in the form of a persona named Tess and from the life of my Great Aunt Mamie Veach Dudley. Mamie\u27s journals and letter to her sister document the memories of the Dudleys including a tragic double suicide, which still haunts the Dudleys almost 100 years later. As narrator and storyteller, my stories connect to those documented by Mamie and link the past to the present. Along with Mamie\u27s family records, I consider other memory-related works by women during the eighteenth and nineteenth centuries including Jane Austen, Anne Bronte, and Emily Dickinson, and I also examine contemporary memory-crafters such as those constructed by altered book artists Tom Phillips and Judith Margolis. Digital memory-craft is another source of support for my argument, and I look at web groups and bloggers. For example, I discuss the Wish Jar Journal, a weblog written by illustrator Keri Smith, where she journals her life and creative process and often mixes textual and visual elements in her blog posts. Writer and blogger Heather Armstrong from Dooce.com is another case study included in this project as her blog is an example of documenting familial events and memoir. Because of their fragmented formats and narrative elements, hardcopy and digitally-based memory-crafts become artifacts which combine text and visual elements to tell a story and pass on knowledge of the everyday through the mixture of text and domestic technology. Memory-craft construction does not follow conventional writing models. Therefore, this provides opportunity for experimentation by those writers who have traditionally been removed from established rhetorical writing methods

FROM CAPTURE TO CARE: ATTENTION, DIGITAL MEDIA, AND THE FUTURE OF COMPOSITION

This dissertation investigates the relationship between digital media and cognition as it emerges in the problematic of attention. Specifically, the project examines the workings of attention across three sites (social, neurological, and technological) in order to argue for a renewed cognitive process theory of writing based in attention studies. Using the ancient pedagogical concept of epimeleias--attending to, taking care--my dissertation asks after the ethical and rhetorical stakes of care in context of contemporary higher education. Ultimately, my dissertation aims to provide a foundation for digital literacy practices--literacy narratives, wiki-writing, remix, audio-visual essays, etc.--in light of the increasing shift towards hybrid and fully digital writing courses and massive open online courses (MOOCs)

Outline of a Subversive Technopoetic: for a Libertarian Pedartgogy

The thesis explores the relationships between knowledge and knowing in contemporary 21st century information society, using the foundation of the Faculty of Media Design & New Media Art at the Nuova Accademia di Belle Arti in Milano as a research apparatus. This Faculty was established between 2003 and 2012, in Milano, Italy. The starting point of the research was established in the hypothesis that technics have tertiarised memory (Stiegler B., 1994), that knowledge is always founded on an ontological pessimism (Queneau R., 1933, Lyotard F., 1979) and on a perpetual process of the generation of meaning (Gadda C., 1923-29, Foucault M., 1966). Knowledge is always and inevitably linked to the technics with which it is passed on. Pedagogy becomes a questioning of the object of knowledge, which transmutes into a definition of the ways it can be visualised. This research then, setting out from a pessimistic position in relation to knowledge and truth, amplifies them to infinite possible forms and therefore causes a dual shift of philosophy towards art and of pedagogy towards hermeneutics. The methodology consisted of a textual and visual description of a territory in a cartography of meaning, seen as the relation between intuition and the way in which practices as knowledges, arts, form remnants

The role of machine learning in personalised instructional sequencing for language learning

The origins of personalised instructional sequencing can be dated back to the times of the Ancient Greeks to the times of Alexander The Great's tutor, Aristotle. However, over the centuries the demand for education and growth of students has been disproportionately greater than the number of teachers in training. Therefore, there has been a longstanding interest in finding a way to scale education without negatively affecting learning outcomes. This interest was fuelled further with the advent of computers and artificial intelligence, where a plethora of systems and models were built to bring technology driven personalised instructional sequencing to the world. Unfortunately, results were far from groundbreaking and many challenges still remain. In my thesis, I investigate three aspects of personalised instructional sequencing: the personalised instructional sequencing mechanism, the student knowledge representation, and human forgetting. While I do not cover the entirety of personalised instructional sequencing, I cover what I consider the foundational components. I link psychological theory to model selection and design in each of my systems and present experiments to illustrate their impact. I show how reinforcement learning can be used for vocabulary learning. I also present a model that uses neural collaborative filtering to learn student knowledge representations. Lastly, I present a state-of-the-art model to predict the probability of vocabulary word recall for students learning English as a second language. The system's novelty lies in the use of word complexity to adapt the forgetting curve as well as its incorporation of psychological theory to select an appropriate model
