Med bakgrund i läraryrkets professionaliseringsprocess, som bland annat efterlyser lärares reflekterande och utvärderande förhållningssätt i sin yrkesutövning, avser denna studie att sammanställa och redovisa lärares erfarenheter av och förhållningssätt till IST-användning främst inom ämnet matematik. Genom att studera andra lärares upplevelser av och förhållningssätt till sitt IST-användande kan man öka sitt egna medvetande. Denna litteraturstudie syftar därför till att öka medvetenheten om de interaktiva skrivtavlornas effekter för matematikundervisningen och lärarens arbete. Studiens resultat visar att de interaktiva skrivtavlorna kan bidra med flera positiva förändringar, men för att det ska bli konkreta effekter för lärarna och undervisningen måste en rad andra förändringar först ske. Den mest framträdande faktorn som framkommit i litteraturen är att lärarna upplever att de behöver få möjligheter till en utökad fortbildning och tid till att utveckla sina tekniska och pedagogiska kompetenser. Litteraturen pekar på att en fullgod fortbildning är avgörande för hur väl den interaktiva skrivtavlan kan integreras i undervisningen och för att lärare ska utveckla en säkerhet i att hantera verktyget.

An Examination of Print and Web Graphics’ Effect on Readers’ Recall Specific research regarding how information graphics, which are defined as charts, maps or diagrams, in print and online affect readers’ recall and understanding of information is scarce at best and at times, even contradictory. Previous print research suggests that information graphics does improve readers’ recall. Online graphics research notes that the freedom of the Web allows readers to learn more efficiently than traditional media. While, other research notes that the Web’s freedom causes users to spend more effort on orienting themselves with the Web site, and therefore, users don’t learn efficiently. This study examined whether the presentation of information graphics affects readers’ recall and found no statistical significance between readers’ recall scores who had read a print graphic and those who read an online graphic. / Department of Journalism

Los Entornos Virtuales de Enseñanza y Aprendizaje (EVEA), o Learning Management Systems (LMS), han sufrido una rápida revolución en los últimos cinco años, fundamentalmente aquellos especializados en el sector universitario. Ello ha determinado que en muchas instituciones de Educación Superior hoy en día coexistan varios entornos virtuales, debido a que fueron adoptados por diferentes unidades académicas en diferentes momentos o etapas, o porque algunas de ellas hayan decidido migrar a otro entorno que en últimos tiempos haya dado un salto cualitativo de importancia o se adapte mejor a su realidad institucional. Tampoco hay un consenso en cuanto a determinar cuál es el mejor EVEA ya que en éste terreno intervienen diversos factores tanto institucionales, como políticos y económicos.

This project created a multi-media work that combined music and visual images in a video format to culminate my graduate studies. I explored computer graphics and video technology while drawing from a multi-faceted background in art. This project attempts to communicate through visual expression the innate qualities of music and sound, while reflecting my interests as an artist. I intend this work to be viewed as either a live performance piece to be accompanied by the piano duet, Sonata for Two Pianos, or as a recording on a computer monitor or television. / Department of Art

This thesis identifies and explores the types of communication modes that exist in video games. Different types of communication are identified and discussed based on Frye's audience centered theory of modes. The inferior communication mode, the mimetic communication mode, the leader-centered communication mode, the romantic communication mode, and the mythical communication mode are all explained. A convenience sample of six video game players were interviewed about video games. An analysis of their self-identification statements revealed that players seek a high level of romantic communication when playing video games. The romantic communication mode makes the video game world an idealized place where the players are able to manipulate their circumstances or show more intelligence than the user in reality. Uses of the communication modes are also explained. / Department of Telecommunications

The study gathered and analyzed data about the impact of interactive television on student achievement and attitude in high school physics classes. Students enrolled in a distance learning program using interactive television to teach physics were the study population. Data were obtained from eighty-five students at six remote sites and the originating site. Z-tests of the mean scores obtained by the study population on each section of the American Association of Physics Teachers/National Science Teachers Association (AAPT/NSTA) Introductory Physics Examination Version 1988R indicated the study population achieved at a level significantly lower than the test norming population in all four areas analyzed. A one-way analysis of variance (ANOVA Model) was completed on achievement data arranged by group according to type of classroom monitoring. Group 1 had certified teachers acting as on-site facilitators; Group 2 had no on-site facilitators. There was no significant difference (p > .05) in achievement between the two groups. A survey was administered to determine the attitudes of students toward interactive television as the method of instruction and to assess student attitude toward the course content. Frequency and percentage distributions of responses to each question on the student survey were descriptive of student attitude. A one-way analysis of variance (ANOVA Model) failed to demonstrate any significant difference at the .05 level in attitudes between the group in classrooms monitored by certified teachers and the group in classrooms which were self-monitored. Students enrolled in the interactive television physics course held slightly more positive than negative attitudes toward interactive television as the method of instruction. Student attitude toward interactive television was less positive after taking the course than prior to taking the course. Students in interactive television classes generally held positive attitudes toward the content of physics. / Department of Educational Leadership

A software Bug report contains information about the bug in the form of problem description and comments using natural language texts. Managing reported bugs is a significant challenge for a project manager when the number of bugs for a software project is large. Prior to the assignment of a newly reported bug to an appropriate developer, the triager (e.g., manager) attempts to categorize it into existing categories and looks for duplicate bugs. The goal is to reuse existing knowledge to fix or resolve the new bug, and she often spends a lot of time in reading a number of bug reports. When fixing or resolving a bug, a developer also consults with a series of relevant bug reports from the repository in order to maximize the knowledge required for the fixation. It is also preferable that developers new to a project first familiarize themselves with the project along with the reported bugs before actually working on the project. Because of the sheer numbers and size of the bug reports, manually analyzing a collection of bug reports is time-consuming and ineffective. One of the ways to mitigate the problem is to analyze summaries of the bug reports instead of analyzing full bug reports, and there have been a number of summarization techniques proposed in the literature. Most of these techniques generate extractive summaries of bug reports. However, it is not clear how useful those generated extractive summaries are, in particular when the developers do not have prior knowledge of the bug reports. In order to better understand the usefulness of the bug report summaries, in this thesis, we first reimplement a state of the art unsupervised summarization technique and evaluate it with a user study with nine participants. Although in our study, 70% of the time participants marked our developed summaries as a reliable means of comprehending the software bugs, the study also reports a practical problem with extractive summaries. An extractive summary is often created by choosing a certain number of statements from the bug report. The statements are extracted out of their contexts, and thus often lose their consistency, which makes it hard for a manager or a developer to comprehend the reported bug from the extractive summary. Based on the findings from the user study and in order to further assist the managers as well as the developers, we thus propose an interactive visualization for the bug reports that visualizes not only the extractive summaries but also the topic evolution of the bug reports. Topic evolution refers to the evolution of technical topics discussed in the bug reports of a software system over a certain time period. Our visualization technique interactively visualizes such information which can help in different project management activities. Our proposed visualization also highlights the summary statements within their contexts in the original report for easier comprehension of the reported bug. In order to validate the applicability of our proposed visualization technique, we implement the technique as a standalone tool, and conduct both a case study with 3914 bug reports and a user study with six participants. The experiments in the case study show that our topic analysis can reveal useful keywords or other insightful information about the bug reports for aiding the managers or triagers in different management activities. The findings from the user study also show that our proposed visualization technique is highly promising for easier comprehension of the bug reports.
