1	Investigating learning with web lectures Day, Jason A. 24 March 2008 (has links) Investigating Learning with Web Lectures Jason A. Day 242 Pages Directed by Dr. James D. Foley Learning can be improved when instructors use classroom time to engage students with hands-on activities and other kinds of active learning. However, time and cost constraints, especially in the higher education domain, can make integrating active learning into course curricula a significant challenge. With this dissertation, we have designed, implemented, and rigorously evaluated an inexpensive, easy-to-implement educational intervention that facilitates increased student engagement and active learning. A key technological component of this intervention is web lectures: condensed, studio-recorded lectures made available via the web as multimedia presentations that combine video of the lecturer, audio, lecture slides, and a table of contents. When web lectures are used to replace the traditional in-class lecture, classroom time can be utilized in other more engaging, learning-beneficial ways. This work is not just about using web lectures, however; it is also about making them with the best combination of modalities (e.g., video, audio, slides, narrative text) and about technologies and pedagogies that bridge the gap between studying web lectures individually and subsequently applying and extending that lecture material in the classroom. We explored the effectiveness of this educational intervention using two complementary threads of investigation. First, we used a controlled, experimental study to evaluate individual s learning with web lectures as standalone learning objects. Here, we found that our web lectures are more effective and efficient than other similar educational multimedia presentations. Second, we used longitudinal, naturalistic studies to evaluate the deployed classroom intervention as a whole. With these studies, we found that a course taught using our web lecture intervention produces as good or better student grades and significantly improved perception of learning and satisfaction than a traditionally-taught course. Guidelines for making and using web lectures are provided.

2	Hypermediale Navigation in Vorlesungsaufzeichnungen: Nutzung und automatische Produktion hypermedial navigierbarer Aufzeichnungen von Lehrveranstaltungen Mertens, Robert 08 November 2007 (has links) In the mid nineties, electronic lecture recording has emerged as a new area of research. The aim behind most early research activities in this field has been the cost-efficient production of e-learning content as a by-product of traditional lectures. These efforts have led to the development of systems that can produce recordings of a lecture in a fraction of the time and also for a fraction of the cost that other methods require for the production of similar e-learning content.While the production of lecture recordings has been investigated thoroughly, the conditions under which the content produced can be used efficiently shifted into focus of research only recently. Employing lecture recordings in the right way is, however, crucial for the effectiveness with which they can be used. Therefore this thesis gives a detailed overview of archetypical application scenarios. A closer examination of these scenarios reveals the importance of navigation in recorded lectures as a critical factor for teaching and learning success. In order to improve navigation, a hypermedia navigation concept for recorded lectures is developed. Hypermedia navigation has proven a successful navigation paradigm in classic text- and picture-based media. In order to be adapted for time based media such as recorded lectures, a number of conceptual changes have to be applied. In this thesis, a hypermedia navigation concept is developed that tackles this problem by combining time- and structure-based navigation paradigms and by modifying existing hypermedia navigation facilities.Even a highly developed navigation concept for recorded lectures can, however, not be put into practice efficiently when production costs of suitable recordings are too high. Therefore this thesis also shows that suitable lecture recordings can be produced with minimal production cost. This endeavour is realized by the implementation of a fully automatic production chain for recording and indexing lectures. eLearning Multimedia Navigation Vorlesungsaufzeichnungen eLectures web lectures SVG Hypermedia lecture recording 54.87 - Multimedia 28 - Informatik, Datenverarbeitung ddc:370
3	Scalable Multimedia Learning: From local eLectures to global Opencast Ketterl, Markus 27 March 2014 (has links) Universities want to go where the learners are to share their rich scientific and intellectual knowledge beyond the walls of the academy and to expand the boundaries of the classroom. This desire has become a critical need, as the worldwide economy adjusts to globalization and the need for advanced education and training becomes ever more critical. Unfortunately, the work of creating, processing, distributing and using quality multimedia learning content is expensive and technically challenging. The work combines research results, lessons learned and usage findings in the presentation of a fully open source based scalable lecture capture solution, that is useful in the heterogenous computing landscape of today’s universities and learning institutes. Especially implemented user facing applications and components are being addressed, which enable lecturers, faculty and students to record, analyze and subsequently re-use the recorded multimedia learning material in multiple and attractive ways across devices and distribution platforms. adaptive multimedia data mining dynamic media objects eLectures e-learning feeds lecture recording learning portals multimedia micro learning m-learning human computer interaction rich internet applications user interfaces mobile development streams web 2.0 web technologies web lectures video based learning visual analytics open source opencast podcasting recommender systems social software social navigation ddc:000 ddc:500 ddc:600 ddc:620
