Lecture capture | Education in Chemistry Blog - 0 views

  • Campus-wide lecture capture technology – a way to record lectures – is a major investment for universities, but is hugely popular among students.
  • Students generally do not expect a professionally produced recording, and are happy provided they can hear clearly, the recording is free from background noise and the video is sufficient.
  • The most common concern about recording lectures is that it will reduce attendance. However, most studies do not support this theory. Of my own students, only 5 out of 99 indicated that recorded lectures influenced their decision to attend. Many pointed out that there is added value in attending a lecture because they are able to ask questions.

  • But with most recordings being released via a virtual learning environment, access can be restricted to students doing a particular course in a particular year.
  • Lecture recordings are an excellent resource for international students grappling with concepts in another language and students with disabilities who may struggle to keep pace. Our students reported that it is nice to have more time to listen to what is being said without frantically trying to write it all down. Many lecture capture systems have ‘hot spot’ metrics that staff can use to discover which portions of a lecture have been reviewed repeatedly. This can indicate concepts that students are struggling with and can enable staff to modify their approach to that concept in future years or provide additional support as necessary. Lecture capture could be used for other applications such as student presentations, demonstrating procedures, providing recordings to support lecture flipping and more. The technology is well established, but our use and how we encourage our students to use it is not. This is an opportunity for innovation when developing our teaching.

5 idées reçues sur le digital learning, Le Cercle - 0 views

  • Idée reçue n°1 : Le digital learning est systématiquement plus économique que la formation traditionnelle
  • Et c'est vrai ! Mais sous certaines conditions...
  • Idée reçue n°2 : Le digital learning se limite aux savoir-faire, il est inopérant à modifier les savoir-être
  • ...7 more annotations...
  • C'est sans compter sur les simulateurs, les serious games et la réalité augmentée.
  • Idée reçue n°3 : Le digital learning est un gage de modernité
  • Il y a donc un risque réel de réaliser et de diffuser des modules de formation obsolètes bien qu'à la pointe technologique.
  • Idée reçue n°4 : Le digital learning est réservé à la jeune génération
  • 48 % des achats en ligne sont effectués par des seniors. Et pour être plus proche de notre sujet, les ménagères de plus de cinquante ans ont très rapidement colonisé le site marmiton.org pour y créer la plus grande plateforme de social learning culinaire !
  • Idée reçue n°5 : Le digital learning se résume à une évolution technologique
  • Il ne suffit donc pas d'investir dans un Learning Management System (LMS) pour réussir la digitalisation de votre offre de formation.

The Future of Holographic Video | American Institute of Physics - 2 views

  • How does it work? The magic happens on the surface of a special crystal called lithium niobate (LiNbO3), which boasts excellent optical properties. Beneath the surface of the LiNbO3, microscopic channels, or "waveguides," are created to confine light passing through. A metal electrode is then deposited onto each waveguide, which can produce surface acoustic waves.
  • Instead of a color wheel, any color combination is possible with their approach simply by altering the frequency of the signal sent to the "white waveguide pixel." In other words, Smalley said, "we can color the output of our display by 'coloring' the frequencies of the drive signal." "As a bonus, this interaction also rotates the polarization of the signal light so that we can use a polarizer to eliminate any noise in the system," he added.
  • This can drop the cost of a holographic video display from tens of thousands of dollars to less than a thousand
  •  
    One future of collaboration displaying that might compete with VR/AR.

Why LinkedIn Corp Spent $1.5 Billion on Lynda.com (LNKD) - 0 views

  • In a blog post from 2013, LinkedIn CEO Jeff Weiner wrote that unemployment is the result of a gap between the skills needed for a job and the skills people have, and he called for an overhaul of the education system. While not nearly as extreme as Weiner's vision for the future of American schools, Lynda.com provides a valuable service to help close that skills gap.

Fostering a culture of learning | Deloitte University Press - 0 views

  • More than eight in ten executives (84 percent) in this year’s survey view learning as an important (40 percent) or very important (44 percent) issue. Employees at all levels expect dynamic, self-directed, continuous learning opportunities from their employers. Despite the strong shift toward employee-centric learning, many learning and development organizations are still struggling with internally focused and outdated platforms and static learning approaches.
  • To facilitate the effort to help employees “learn how to learn,” L&D teams are building internal knowledge-sharing programs, developing easy-to-use portals and video sharing systems, and promoting collaborative experiences at work that help people constantly learn and share knowledge.
  • Almost $1 billion of this went into tools, content, and companies that focus on the corporate market.6

  • Much of this investment is directed at tools to harness video, new mobile learning apps, and an explosion of content marketplaces. Today, any employee can browse through content from Coursera, Udemy, Udacity, or a dozen other providers and instantly access a lecture, course, or workshop on a needed skill. Such platforms offer learning opportunities at little or no cost and even allow employees to interact online with experts in the field—learning exactly what they need, when they need it, at a time that fits their schedules.

MOOCs Are No Longer Massive. And They Serve Different Audiences Than First Imagined. | ... - 2 views

  • Actually these days you don’t hear much about MOOCs at all. In the national press there’s almost a MOOC amnesia. It’s like it never happened.
  • Shah is our podcast guest this week, and he argues that MOOCs are having an impact, but mainly for people who are enrolling in MOOC-based degrees, where they can get a credential that can help them in their careers without having to go back to a campus. Of course, that’s a very different outcome than the free education for the underserved that was originally promised.
  • I think it's still new, so colleges think that if they get in now they might establish the degree and maybe capture the market early. I think it's a bigger advantage for smaller universities than the bigger because they get to sort of undercut the big players. For many colleges, they might be locally well-known but not globally. They get a chance to reach more users plus it's good money if it works out.

  • What about the students? Who are the people who end up taking these MOOCs?It's extremely diverse, the ones who end up paying for them, usually it's people like me who are out of the education system and looking for a promotion or a new job. There's an entire group of people where just one dollar is too much—they only want free. But, there's another group of people where if they are charged $900 or $1,200 bucks, it’s not a big difference (and they’ll pay either). And then if you know the outcome could be getting 5 percent or 10 percent increase in salary over a lifetime, [you realize] you recoup that money very quickly.
  • In the earliest days of MOOCs, which had large communities, [it was easier for students]. The community provided the support and the encouragement. Now, MOOCs are no longer massive. The community engagement is not there, so that makes it more difficult [for many students]. But community isn't really a feature that people sign up for. The reason people pay is the credential. So unfortunately community has fallen down the priority list of the designer of these products

The future of college education: Students for life, computer advisers and campuses ever... - 0 views

  • “We are living in an incredible age for learning, when there’s so much knowledge available, that one would think that this is good news for higher education,” Bryan Alexander told me recently. Alexander writes often about the future of higher education and is finishing a book on the subject for Johns Hopkins University Press. “Yet we’ve seen enrollment in higher education drop for six consecutive years.”
  • In 2015, Georgia Tech formed a commission on the future of higher education, and its 48 members were asked to imagine what a public research institution might look like in 2040.
  • The primary recommendation of the Georgia Tech report is that the university turn itself into a venue for lifelong learning that allows students to “associate rather than enroll.” Such a system would provide easy entry and exit points into the university and imagines a future in which students take courses either online or face-to-face

  • The commission outlines a scenario in which artificial intelligence and virtual tutors help advise students about selecting courses, navigating difficult classes and finding the best career options.
  • A distributed presence around the world. Colleges and universities operate campuses and require students to come to them. In the past couple of decades, online education has grown substantially, but for the most part, higher education is still about face-to-face interactions. Georgia Tech imagines a future in which the two worlds are blended in what it calls the “atrium” — essentially storefronts that share space with entrepreneurs and become gathering places for students and alumni. In these spaces, visiting faculty might conduct master classes, online students could gather to complete project work or alumni might work on an invention.

How Will IoT Change the Education Sphere? | Emerging Education Technologies - 0 views

  • According to a research study, “IoT in Education Market” by MarketsandMarkets, the global market size is expected to “grow from $4.8 billion in 2018 to $11.3 billion by 2023.”
  • Personalized Learning One of the biggest hurdles with the typical education system is the lack of flexibility in the course work. The course is the same for each and every student. The human-to-human interaction in a classroom space is collective and does not take into account the individual pace and needs of the student. Building on the idea of Big Data collection, with IoT each student can be evaluated and monitored on an individual basis. Weaker students may be granted a modified course work that caters to them individually to bring them up to speed. On top of that, the aggregate data can guide the instructors to modify the coursework on the go depending on the collective class needs.
  • More Human-to-Machine Interaction
  • ...2 more annotations...
  • Thus IoT has the potential to not only save time and physical resources, but also human resources all the while maintaining a better standard of teaching.
  • Financing Issues Financing is another hurdle. Government expenditure on Education is already stretched to its limit in most countries around the world. Plus, education isn’t really the sector that sees significant improvement in budget increase every fiscal year. It is general knowledge that education is kept on the back burner since it is not the topic that wins votes. Information Technology hardware can be expensive and IoT infrastructure can demands a lot of it. To implement IoT, either government or private investments may need to subsidize it.

Students, teachers split on value of video-recording lectures - 0 views

  • The study focused on the Echo360 system Swinburne introduced in 2014. Under the scheme, lectures are automatically recorded unless academics opt out — something few have done, Dr Pechenkina said.Overall, 71 per cent of students said lecture recordings helped them, and 70 per cent wanted more of it. Just 28 per cent of academics wanted more of their classes recorded, with most saying they would prefer lectures were not taped at all.
  • While lecture-recording provides greater flexibility for students, “it has the potential to do the opposite for lecturers — particularly those whose teaching approach or subject material does not lend itself readily to current models of recording”.The paper says technological developments could spawn new ways of recording, enabling lecturers to tailor their approach to the cameras. But this, of course, could “further decrease student attendance at lectures”.Dr Pechenkina said lecture recording was unlikely to disappear anytime soon. “We need to train academics better in how to use the technology to enhance their teaching.” She said new advances would make recording less restrictive, with cameras able to “move around and capture widely what goes on in the classroom. The capacity is there, or it can be there within a very short period.”
  • Dr Pechenkina said academics were also using the technology to prerecord and disseminate lectures ahead of time, allowing class time to be focused on group discussion

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

  • Though there is no one-size-fits-all solution for audio capture, one- and two-channel systems are the norm for voice lift and lecture capture
