Para el desarrollo de la investigación, se utilizó la metodología orientada a la multimedia Briam Blum, la cual toma en cuenta el diseño institucional. Con su implementación se llegó a la conclusión, que los niños con Síndrome de Down del nivel primario de la institución en estudio, pertenecientes al grupo experimental, que hicieron uso de la tecnología, adquirieron con mayor rapidez y de forma más consolidada conceptos como el conteo y cantidad que aquellos que únicamente aprenden a partir del método tradicional, mejorando sus niveles de rendimiento académico, permitiendo así, afirmar que el uso del sistema multimedia educativo, optimiza y cumple el rol de herramienta reforzadora del aprendizaje en personas con Síndrome de Down. / Tesis

Doctor of Philosophy / Department of Curriculum & Instruction / Margaret Gail Shroyer / Compared to other nations, fewer American students are pursuing and completing degrees within the science, technology, engineering, and mathematics (STEM) fields. For the United States to remain competitive, the development of novel instructional techniques designed to reach students who might otherwise be lost from these majors is imperative. This study examined the use of teacher designed multimedia within an introductory STEM course. Quantitative methods were used in a real classroom setting to examine the relationship between the use of multimedia and the amount of information students comprehended and retained when learning photosynthesis. Also, the relationship between the use of multimedia and the learning gains of female students within introductory STEM courses was examined, as their participation within the STEM fields has historically been low. Qualitative methods were employed to discern which multimedia features students and instructors found the most beneficial regarding the presentation of complex and abstract scientific concepts. Using a quasi-experimental, design-based research approach, it was determined that the use of simple animations and corresponding narration increased student learning gains compared to the use of static pictures and text. This finding aligned well with theories regarding multimedia learning and its use of dual coding for reducing cognitive load. The value of multimedia for learning gains was greatest for females with lower prior knowledge levels, as defined by performance on a pre-test. However male students with low prior knowledge benefited, although not to the same degree as females. In agreement with the fundamentals of constructivism, this finding supported the idea that basic schema construction is paramount for increasing comprehension. Results from the qualitative portion of the study indicated that students prefer multimedia over static text and pictures because: 1. Complex processes can unfold in motion while being described verbally 2. Schema construction is guided by a trusted source, and 3. Small chunks of information can be presented yet tied together in a larger sequence.

Con este proyecto de tesis se pretende consolidar la información del estudio realizado a la empresa Cineplanet dentro del área de ventas del cine. A partir de ello, se considerará el modelo de gestión de la empresa y análisis de la relación entre ejecutivos y trabajadores clasificados por niveles funcionales, de modo que se puedan identificar las formas del servicio brindado. Una vez creado el modelo, éste permitirá concentrarse en la principal necesidad de la empresa, la disminución de las largas colas en boletería; encontrando como causa principal la demora en la compra y pago de entradas dentro del cine. Teniendo en cuenta la idea anterior, primero, se analizará el flujo de ventas que maneja la empresa y posteriormente, se abordarán los resultados cuantitativos obtenidos mediante la encuesta realizada a los espectadores frecuentes del cine. Finalmente, se concluirá con el desarrollo e implementación de un sistema multimedia interactivo asociado a un monedero electrónico que permita al espectador adquirir su entrada de forma fácil y rápida, tener buena información sobre las películas en cartelera y contar con un recurso, como lo es el monedero electrónico, que permita tener mayor seguridad en cuanto a la portabilidad de su dinero.

Syftet med föreliggande studie var att undersöka elevernas upplevelser och erfarenheter av IKT-stöd i undervisningen i idrott och hälsa och hur användningen av IKT bidrog till deras lärande. Den metod som användes i studien var kvalitativa intervjuer genom stimulated recall och nio elever från en högstadieskola intervjuades. Eleverna som intervjuades i studien hade deltagit i IKT-stödd undervisning under en tvåårsperiod där en del av lektionerna spelades in på video. Videodokumentationens syfte var att bilda en bakgrund till det eleverna beskrev senare i intervjuerna. Den teoretiska utgångspunkten var sociokulturellt perspektiv som i studien innebar att eleverna samverkade med varandra, men också med artefakter, såsom bollar, linjer, gymnastikredskap eller IKT redskap som i det här fallet binder ihop elevernas handlingar. Studien visade att eleverna hade positiva erfarenheter av IKT-stöd i undervisning i idrott och hälsa. Med IKT i undervisningen fick eleverna både utbildning och underhållning som uppskattades av många. Studien visade också att IKT- stöd hade en positiv inverkan på elevernas lärande i ämnet idrott och hälsa och att idrottsundervisning med IKT-stöd underlättade lärande och gjorde information och instruktioner mer förståeliga. Detta ledde till att elevernas engagemang förbättrades, fokus och motivation ökade vilket samtidigt resulterade i att eleverna faktiskt lärde sig snabbare. / The aim of the present study was to investigate students' perceptions and experiences of ICT support in education in physical education and how the use of ICT contributed to their learning. The methodology used in the study was the qualitative research with stimulated recall. Students from an upper secondary school were interviewed. The interviewed students had participated in ICT-assisted learning during a period of two years in which some of the lessons were recorded on video.The purpose of video recording was to stimulate the students’ experiences, later described in the interviews. The video clips of some lessons were shown during the interviews. The theoretical starting point was a socio-cultural perspective. In the study that meant that the students interacted with each other, but also with artifacts such as balls, lines, gymnastics equipment and ICT tools who in this case linked the movements of the students. The study showed that the students had positive experiences with ICT support in the learning of physical education. When ICT was used many pupils enjoyed both the educational moment and the entertainment it provided. Another aspect of the study was that the ICT support facilitated easier learning and by making information and instructions more understandable. This resulted in improved student engagement, better focus and increased motivation, which actually also lead to faster learning. / ICT, physical education, teaching, learning, exergames, multimedia

A área de recuperação de informação baseada em conteúdo visual vem ganhando importância graças ao volume de material visual existente (imagens e vídeo digitais), compartilhado e distribuído principalmente via Internet, e à capacidade de processamento alcançada pelos computadores pessoais na última década. Novas formas de consumo, manipulação e exploração de vídeo digital podem ser criadas através da organização e indexação apropriada desse material. A delimitação de tomadas fornece uma base para a abstração e estruturação de vídeo, agregando quadros contíguos em seqüências de mesmo contexto, isto é, trechos com unidade em termos de tempo e espaço. Nesta dissertação são apresentados os conceitos básicos de delimitação de tomadas e métodos tradicionais utilizados nesse tipo de segmentação, bem como vários resultados experimentais obtidos a partir de seqüências reais de TV. É analisada a distribuição das diferenças entre quadros sucessivos, calculada através de seus histogramas, na tentativa de caracterizar as transições entre tomadas e obter melhores parâmetros para a segmentação. Obtêm-se experimentalmente mais evidências que comprovam a superioridade da medida de intersecção de histogramas sobre outras medidas. A principal contribuição do trabalho consiste no desenvolvimento de um algoritmo baseado no método twin-comparison, que apresenta melhor desempenho que o método original na detecção dos limites de tomadas por utilizar análise local da variação visual entre os quadros do vídeo. / Visual content based information retrieval is an area of increasing importance due to the large volume of available material (digital images and videos), shared and distributed mainly by the internet, and the processing power achieved by personal computer in the last ten years. New ways to consume digital video and to manipulate and explore its visual information can be made by appropriately organizing and indexing this material. The shot boundary detection is a fundamental tool to video abstraction and structuring, combining near frames into sequences with similar context, segments with space and time unity. This work presents the basic concepts about shot boundary detection, traditional methods used and several experimental results obtained from a real TV data set. The distribution of differences of neighboring frames, calculated from histogram comparison, is used to define the transitions between frames and to obtain better parameters for segmentation. Our experimental results show the superiority of the histogram intersection method over other measures. Our main contribution is the development of a new algorithm based on the twin-comparison method, extended with local analysis of visual content variation between video frames. This algorithm was tested over hours of TV data, and performs better than the original method.

My thesis body of work offers a bridge into the physical, emotional, and spiritual scarring caused by global intolerance towards the LGBTQIA+ community and oppression embedded by patriarchal power. This body of work is a collection of resurfaced history and experiences transformed physically by intentionally subverting hyper-masculine materials into knots. My objective is to deconstruct individual knotted cords that make up the fabric of my identity and reconstruct them into an installation. Renascence offers a visceral experience for the audience that aesthetically explores the body’s transformation as it heals. This thesis asserts a place within a reflective, fluid, transitional identity expressing the intersection of the temporality and body that I occupy as a Queer, Latinx artist of color. Working across media, Renascence incorporates performance, photography, paper, paint, projection, mirrors and built environments. / Includes bibliography. / Thesis (M.F.A.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection

El usuario a través de su receptor televisivo será capaz de ejecutar la aplicación interactiva y por medio del control remoto o la pantalla táctil del teléfono móvil podrá navegar por el menú de opciones de la aplicación. Se planteó un sistema de votación en el cual el usuario podrá elegir entre dos programas, el ganador será transmitido en el horario estelar. El usuario a través del envío de SMS podrá votar por su favorito. Con el uso de los SMS como canal de retorno de la aplicación se logra la inclusión de la red móvil en el diseño de la red de interactividad de los canales de televisión. El archivo Transport Stream (TS) contendrá los servicios del canal de televisión. Para la generación del TS se utilizó las herramientas OpenCaster y FFmpeg. La aplicación interactiva que será transportada por el TS fue desarrollada en lenguaje NCL-Lua y contendrá el servicio de votación. La tarjeta de transmisión TVB593 transmitirá el archivo TS bajo los parámetros del estándar ISDB-Tb. En la recepción se comprobará el correcto funcionamiento de la aplicación interactiva y la señal de audio y video del canal de televisión con el uso de los set top box EITV Developer y DigiTV. El usuario enviará un SMS con la opción de votación. El modem GSM obtendrá todos los SMS que serán almacenados en la base de datos SMS_db con el uso de la herramienta SMSEnabler. La aplicación del administrador obtendrá los resultados finales y copiará el archivo TS del programa ganador a la carpeta de producción del transmisor. Se utilizó la herramienta MPEG2 Analyzer para el análisis del archivo Transport Stream. Se utilizó el 52,7 % de la capacidad total del archivo TS para la trasmisión de los contenidos de alta definición, definición estándar y oneseg del canal. El 47,8 % restante podría ser utilizado para transmitir otros servicios o más datos de interactividad. Se realizaron pruebas de recepción de los tres servicios transmitidos por el canal de televisión. Además la aplicación interactiva fue probada en los formatos de alta definición y definición estándar para validar su correcto funcionamiento en escenarios multiplataforma. / Tesis

POPULATION: 36 fifth grade classrooms, randomly selected from cities and towns within 50 miles of the city of Boston, Massachusetts. PROCEDURE: 36 teachers took part in the study. 12 of these were trained in the use of problem-solving methods with the teaching of natural science; 12 were trained in the use of information-giving methods with the teaching of science; and 12 were given no specific training and functioned as a control group. Two television series containing 20 one-half hour programs on the natural sciences were televised by WGBH-TV, Educational Television in Boston, Massachusetts. Ten programs were identical for both series. The other ten programs covered the same content areas, but were different in organizational make-up. Ten series "R" programs stressed the giving of information, ready-made concepts, and generalizations. Ten series "E" programs stressed the postulation o.f problems, time lapses for student response and posing of solutions. Classroom teachers in the two experimental classroom groups were provided with manuals correlated with the two experimental television series of ten programs. Although basic concepts to be covered were identical, one manual stressed the learning of information, the other the solution of problems. Four tests were administered during the experiment: The Otis Self Administering Intelligence Test (Beta Form) to establish distribution of intelligence; a Science Information Test to evaluate the learning of facts; a Science Concept Test to evaluate ability to solve problems; and a Science Reasoning Test to assess ability to reason logically. All tests were administered prior to the initiation of the television series in October 1961. All except the Otis were administered again immediately at the conclusion of the television series in April 1962. The Minnesota Teacher Attitude Inventory was administered in October 1961 to participating teachers as an aid in validation of teacher selection. The experimental design consisted of three groups of 6 classes viewing each television series, and two groups of 6 classes experiencing each of three classroom treatments. RESULTS: There were no statistically significant differences by either television treatment or classroom treatment. There were, however, differences in measured IQ between boys in different groups. Reliabilities of the tests used ranged between .85 and .92. Two significant results should be mentioned: 1) Note-taking in class, although not initially considered as a variable was a significant factor in experimental outcome; and 2) the basic assumptions for the use of difference scores as raw data for analysis of variance proved untenable with data collected for the study and corrections in difference scores for both ceiling and floor effects needed to be made. These corrections of gain scores changed some previously significant results to non-significant results. Approximately 75 per cent of the predictions of the direction of difference of group means by hypothesis were accurate. CONCLUSIONS: In an experiment of this sort, many variables which prejudice outcomes are not fUlly understood. Difference scores as raw data for statistical analyses are subject to distortion. It would seem that inductive problem-solving, is at the least, as effective as information-giving in the learning of natural science by fifth graders. / 2031-01-01
