    The World-Wide Web has become the predominant platform for computer-aided instruction. Contentorientation, access and interactive features have made the Web a successful technology. The Web, however, is still evolving. We expect in particular Semantic Web technology to substantially impact Web-based teaching and learning. In this paper, we examine the potential of this technology and how we expect it to influence content representation and the work of the instructor and the learner

    Investigating Correlations of Automatically Extracted Multimodal Features and Lecture Video Quality

    Ranking and recommendation of multimedia content such as videos is usually realized with respect to the relevance to a user query. However, for lecture videos and MOOCs (Massive Open Online Courses) it is not only required to retrieve relevant videos, but particularly to find lecture videos of high quality that facilitate learning, for instance, independent of the video's or speaker's popularity. Thus, metadata about a lecture video's quality are crucial features for learning contexts, e.g., lecture video recommendation in search as learning scenarios. In this paper, we investigate whether automatically extracted features are correlated to quality aspects of a video. A set of scholarly videos from a Mass Open Online Course (MOOC) is analyzed regarding audio, linguistic, and visual features. Furthermore, a set of cross-modal features is proposed which are derived by combining transcripts, audio, video, and slide content. A user study is conducted to investigate the correlations between the automatically collected features and human ratings of quality aspects of a lecture video. Finally, the impact of our features on the knowledge gain of the participants is discussed

    Facilitating the creation of interactive multi-device Learning Objects using an online authoring tool

    Learning Objects facilitate reuse leading to cost and time savings as well as to the enhancement of the quality of educational resources. However, teachers find it difficult to create or to find high quality Learning Objects, and the ones they find need to be customized. Teachers can overcome this problem using suitable authoring systems that enable them to create high quality Learning Objects with little effort. This paper presents an open source online e-Learning authoring tool called ViSH Editor together with four novel interactive Learning Objects that can be created with it: Flashcards, Virtual Tours, Enriched Videos and Interactive Presentations. All these Learning Objects are created as web applications, which can be accessed via mobile devices. Besides, they can be exported to SCORM including their metadata in IEEE LOM format. All of them are described in the paper including an example of each. This approach for creating Learning Objects was validated through two evaluations: a survey among authors and a formal quality evaluation of 209 Learning Objects created with the tool. The results show that ViSH Editor facilitates educators the creation of high quality Learning Objects

    Visual literacy for libraries: A practical, standards-based guide

    Get PDF
    When we step back and think about how to situate visual literacy into a library context, the word critical keeps coming up: critical thinking, critical viewing, critical using, critical making, and the list goes on. To understand our approach, start with your own practice, add images, and see where it takes you. Do you encourage students to think critically as they research? How can you extend this experience to images? Do you embrace critical information literacy? Can you bring visual content to enrich that experience? Do you teach students to critically evaluate sources? How can you expand that practice to images? You’ll see a lot of questions in this book, because our approach is inquiry- driven. This is not to say that we don’t cover the basics of image content. Curious about color? Covered. Not sure where to find great images? We’ll show you. Wondering what makes a good presentation? We talk about that too. But what we really want you to get out of this book is a new understanding of how images fit into our critical (there it is again) practice as librarians and how we can advance student learning with our own visual literacy. This book grounds visual literacy in your everyday practice—connecting it to what you know and do as a librarian who engages in reflective practice. Heidi Jacobs put it well when she argued that, for information literacy pedagogy, “one of the best ways for us to encourage students to be engaged learners is for us to become engaged learners, delve deeply into our own problem posing, and embody the kind of engagement we want to see in our students” (Jacobs 2008). We extend this viewpoint to visual literacy pedagogy and provide many opportunities for you to embody the kind of visual literacy that you want to develop in your learners
