Have Your Say : Tell your VC - 2 views

  • When the issue of lecture capture (KentPlayer) was raised, Cox directed the question back at the audience, asking: “What are you actually using it for?”. It seems the issue among staff, with regard to lecture capture, is the assumption that students will not show up to their lectures if they know they will be available to listen to later. Many members of the audience proved themselves to be evidence of the contrary, with one student saying: “If I’m doing an essay I’ll go to that particular lecture and revise it again… (replaying lectures can also be useful for revision) because the lecturers elaborate on a particular point that you probably don’t remember, especially if your exams are always in June”. Many other students agreed that the recordings are useful for revision as well as recapping parts of lecture you may not have fully taken in or understood. One member of the audience who has dyslexia said they were useful for him in going back and making notes. The downfall of lecture capture, is the sound quality. One audience member said that although he finds lecture capture useful, the sound quality can make it hard to hear and sometimes render the recording useless. Currently, lectures are recorded by camera only, however, McMahon revealed that the University is looking into introducing lapel mics: “Some of our academic colleagues are concerned that their style is that they really like to pace around and move in and out of the audience.” The introduction of lapel mics could potentially be the solution to lecturers’ aversion to lecture capture as well as the issue of sound quality.

Wowza Predictions for Online Video in 2015: the flipped classroom becomes real - 0 views

  •  
    Online video has been growing as a primary tool for distance learning, and now it's picking up more speed within education for a second reason. Flipped classroom experiences allow teachers to assign lecture videos to be watched outside the classroom, allowing them to spend more quality group and individual time with students in the classroom and resulting in positive learning results. There's a long-term multiplier effect here, too - as these students enter the workforce, they'll be taking expectations for these new modes of video learning and consumption with them to their employers.

Reinforcing Training With Video-Based Learning | Learning Technologies | Training Industry - 1 views

  • Instructors were specifically trained for corporate audiences in order to further strengthen impact. What we lacked was sustainability, which is necessary for ensuring that the learner grasps the material and is able to apply it successfully in his or her work. Only then would training truly result in improved quality of work and long-term benefits for the organization. Here’s an example of how to use a video-based platform to reinforce training and achieve these long-term benefits.
  • The main objective of training is for learners to apply new skills in the long term. The key is to reach out in a way that is appealing and involves the learner. Technology-enabled learning has made this level of engagement possible, and with the emergence of new technologies, it will continue to do so in fresh and innovative ways.
  •  
    The library consisted of more than 30 modules and 50 podcasts, with more in development. Each module was kept short - less than nine minutes of learning time - so that the learner's attention would not waver. The graphics were light so that learners could view them on different devices. In addition to being visually impactful, all modules had a clear voiceover that caught the learner's attention and retained it for the entire duration of the module. The podcasts were also appealing to learners who preferred listening to a short commentary and gaining insight immediately.

Why do German students choose to study in the UK? | Times Higher Education (THE) - 1 views

  • Freed of exorbitant university fees, German students enjoy higher education of a comparably high standard that usually does not see them graduate with a huge pile of debt that then has to be paid off.  Still, a large number of German students decide to leave the “land of poets and thinkers” to pursue degrees at universities in the UK. Despite the costs and the tough application process, about 7,500 Germans head to the UK every year to take up their studies at universities in Oxford, London or Edinburgh, among other destinations.
  • The crucial factors are tuition quality and the staff-to-student ratio, which many Germans who have spent time studying in the UK say is excellent. With an average ratio of 1:66, German universities have a hard time standing their ground in this regard against rivals in the UK.  For comparison, Bishop Grosseteste University in England, considered one of the “worst” universities with respect to its staff per student number, has an average ratio of 1:25,

Lecture capture: software and hardware collaboration - Installation - 1 views

  • Panopto’s third generation capture tools record from virtually any video or audio device that can be plugged into a laptop and can capture and play multiple simultaneous video feeds, slides, images and screen recordings.
  • However, the choice of lecture capture software is affected by the selection of hardware, and this can be a problem. As Dean Offord, European sales engineer for Panasonic Business, points out: “At the moment compatibility between software and hardware is not as universal as vendors of either would like. Simple integration is incredibly important within AV. That is why Panasonic ProAV has recently developed the new Virtual USB driver to configure the Panasonic PTZ line-up with popular lecture capture systems over IP with a single Cat5e or Cat6 for high-definition capture
  • Collaborations between lecture capture hardware and software companies are a great way to offer a full systems package to educational institutions, giving peace of mind of a reliable and high quality system.

  • The benefit to users lies in simplicity of operation. Phil Waterhouse, business development manager for education at Crestron UK, says: “Some of the partnerships are working very well; it means installing and programming is not as difficult. Crestron and Panopto, for example, have a partnership that means a simple-to-use interface is readily available
  • “Collaboration enables solutions in which the sum greatly exceeds the parts. Universities and colleges of higher education are obliged to provide text transcripts of videos for hearing-impaired students. Automated search features are also essential, allowing students to quickly access specific parts of a lecture. Students will only use a small section of a lecture during revision so it is essential that they can reach the relevant part quickly, without having to scan the whole video. Traditionally, preparation of captions involves people listening to the soundtrack and typing. Advanced speech-to-text software automates this process, reducing the cost of production massively – from around $1 per minute to less than two cents.”
  • There is huge potential for the technology to be able to offer collaborative learning in a way that currently can’t be done due to video transmission latency and limited bandwidth. At the moment universities have successfully deployed lecture capture, storage and playback systems but in the future they are likely to move more towards distributed classrooms, huddle spaces, cross-campus collaboration and more interactivity between remote groups of students and teachers.

Here's How Engaging Digital Tools Level the Playing Field | Emerging Education Technolo... - 0 views

  • Classrooms have plenty to share with one another from one area to another, which this platform would allow, and I really like having the kids join me live, ask questions back and forth or collaborate on a single podcast. Accessibility is key to ensuring that every student has access to a quality education, and the live transcript feature would also be very useful for our English language learners. You can’t learn a language unless you speak it, write it and work with it. From a personal perspective, I have a hearing deficiency and appreciate that we now have this tool to amplify one’s voice so that everyone can better hear what we’re saying. I actually recorded a four- or five-minute rant on Storytellers about the challenges I face at conferences when speakers don’t use microphone because they’re uncomfortable about it, and shared it to Spotify. Too often, we're focused on the specifics of how kids are sharing information rather than what they're sharing. Kids need options. If they don’t want to write that paper or present in front of the class way to show what they’ve learned, a podcast can support the same outcome.

In Streaming, Audio Plays the Lead Role | AvNetwork.com - 2 views

  • The most important thing about live-streaming isn’t video—it’s audio. Varvid CEO and founder Aaron Booker can’t stress this enough. “People are very forgiving about video; they’re not forgiving at all about audio.” He points to the tiny microphones in smartphones as the main reason they shouldn’t be used for streaming. “The video [from smartphones] can be pretty amazing these days. However, the audio is just not what it needs to be and will not reflect well on anybody.”
  • “But if you want something really flexible and portable because you have events that are happening in different places—then you’re going to need to invest in a good soundboard, good microphones, and most importantly in somebody’s skill set so that they can manage that for you.”
  • To present all speakers clearly and at the same volume, DSP is used to process the audio feeds to compensate for the size and shape of the room and the environmental factors that impact audio quality, including reverberation, acoustics, and where people are positioned
