2 Outline Massive Open On-Line Courses – MOOCs Brief History of MOOCs Types of MOOCs Major players in MOOCs MOOCs players in Europe Platforms for creating Courses Coursera & edX Cases

3 Massive Open On-Line Courses (MOOCs) http://en.wikipedia.org/wiki/Massive_open_online_course http://en.wikipedia.org/wiki/Massive_open_online_course MOOC is an online course aimed at unlimited participation and open access via the web Not only traditional course materials such as videos, readings, and problem sets, MOOCs provide interactive user forums that help build a community for students, professors, and teaching assistants MOOCs are a recent development in distance education which began to emerge in 2012

4 Why offer a MOOC http://www.slideshare.net/beboac/ichl-moo-cs http://www.slideshare.net/beboac/ichl-moo-cs

5 History of MOOCs (I) A MOOC is an open education movement and is found online It influences connectivism where learning is successful and networks are created in different fields 2002: MIT OpenCourseWare project formed 2004: The term Connectivism was developed by George Siemens (University of Texas at Arlington) and Stephen Downes (Canada's National Research Council) 2008: The first MOOC was presented at the University of Manitoba, Canada and it consisted of 2200 learners 2008: Khan Academy starts up (actually at 2006) 2010: Dave Cormier (University of Prince Edward Island) made video about MOOCs and uploaded onto YouTube 2012: Harvard’s first MOOC has 370,000 students, New York Times calls 2012 the year of the MOOC 2013: cMOOCs and xMOOCs too numerous to count

6 Stephen Downes’ MOOC Model http://www.slideshare.net/beboac/ichl-moo-cs http://www.slideshare.net/beboac/ichl-moo-cs Four elements for a successful MOOC: – Autonomy – students decide how much to participate – Diversity – students come from all backgrounds, different countries, different experiences – Openness – MOOCs should be free or with low cost – Interactivity – Chats, video meetings… In his new book: Learning is the creation and removal of connections between the entities, or the adjustment of the strengths of those connections. A learning theory is, literally, a theory describing how these connections are created or adjusted

7 The different types of MOOCs (I) http://en.wikipedia.org/wiki/Massive_open_online_course#Connectivist_design http://en.wikipedia.org/wiki/Massive_open_online_course#Connectivist_design There are different types of MOOCs: – The cMOOC (connectivist MOOC): the first MOOC ever offered was a cMOOC The term describes a MOOC where people learn through social networks e.g. blogs with a focus on knowledge creation instead of acquisition cMOOCs are used by the individual, academics and non profit organizations the cMOOC is based on a connectivist learning theory the cMOOC is an informal learning environment

8 The different types of MOOCs (II) The xMOOC: – xMOOCs are used by the Universities – xMOOCs use a behaviourist approach – the xMOOC is a more formal learning environment, it focus purely on knowledge acquisition – EdX can be characterized as xMOOC – MIT announced MITx at the end of 2011, MITx is morphed into EdX with the addition of Harvard and UC Berkley (EdX 2012)

9 Synchronous Massive Online Course - sMOOCs http://www.slideshare.net/beboac/ichl-moo-cs http://www.slideshare.net/beboac/ichl-moo-cs This term was coined at University of Texas in August 2013 A course that features live, synchronous broadcasts to students Coursera MOOCs could be characterized as a standard MOOCs or an sMOOC

10 Platforms for creating Courses (Modular object-oriented dynamic learning environment - Moodle) (I) https://moodle.org/ http://webvm.netmode.ntua.gr/courses https://moodle.org/ http://webvm.netmode.ntua.gr/courses Moodle is a free online learning management system, or LMS Written in PHP and distributed under the GNU General Public License Moodle runs without modification on Unix, Linux, FreeBSD, Windows, Mac OS X and any other systems that support PHP and a database, including webhost providers Moodle allows for extending and tailoring learning environments using community sourced plugins

11 Platforms for creating Courses (Open edX) (II) http://code.edx.org/ http://code.edx.org/ Open edX is a not-for-profit enterprise Founded 2012 Open edX – is implemented mostly in Python for the server, and Javascript for the browser – the code is being made available under an AGPL license – the main repository is edx-platform which includes both the LMS and the authoring tool, Studio Open edX is already receiving code contributions from around the world (e.g. Stanford University, Google, MIT, The University of Queensland, Tsinghua University, UC Berkeley, and Harvard University)

12 edX Platform Stack Almost all of the server-side code in Open edX is in Python, with Django as the web application framework, using Mako templates (written in Python) The browser-side code is written primarily in JavaScript. Some of the code is written in CoffeeScript, and edX is working to replace that code with JavaScript. Parts of the client-side code use the Backbone.js framework (available under the MIT software license), and edX is moving more of the codebase to use that framework Open EdX uses Sass and the Bourbon framework for CSS code

13 Platforms for creating Courses (III) CourseSites by Blackboard is an exceptionally robust platform – it has all of the features that Moodle has – including extensive teaching tools – reporting features and SCORM (Sharable Content Object Reference Model) compliance – it is also cloud-based – you can set up a course in minutes and never have to worry about maintenance or upgrades Udemy is a platform or marketplace for online learning and is specialized in the private MOOC – think of it as the YouTube of MOOCs – instructors can build and host their own courses on the platform and then offer them to users for free or for a fee Versal is a new platform, create interactive e-learning courses for your LMS – intuitive user interface and a robust drag-and-drop functionality – a user can sign up for free and then build a course that includes mathematical expressions, image drill-downs and many more widgets, all without any coding knowledge – users can also embed their published courses on other websites, such as personal blogs

16 Major Players in the MOOC Universe http://chronicle.com/article/The-Major-Players-in-the-MOOC/138817/http://chronicle.com/article/The-Major-Players-in-the-MOOC/138817/ Coursera: This for-profit MOOC founded by Andrew Ng and Daphne Koller (Chief Scientist at Baidu Research in Silicon Valley) has teamed up with 62 colleges (and counting) for its classes. It attracted $22-million in venture capital in its first year Khan Academy: Salman Khan (American teacher) made waves when he quit his job as a hedge-fund analyst to record short video lectures on everything from embryonic stem cells to—you guessed it—hedge funds and venture capital Udacity: This for-profit MOOC, started by the Stanford professor Sebastian Thrun, works with individual professors to offer courses. By March 2013, Udacity had raised more than $21-million in venture capital. Udacity provides with Nanodegrees to learners EdX: Harvard and MIT put up the original $60-million to start this non-profit MOOC

17 Overview of potential revenue sources for three MOOC providers edXCourseraUDACITY Certification Secure assessments Employee recruitment Applicant screening Human tutoring or assignment marking Enterprises pay to run their own training courses Sponsorships Tuition fees Certification Employers paying to recruit talented students Students résumés and job match services Sponsored high-tech skills courses "Charging for content would be a tragedy," said Andrew Ng. But "premium" services such as certification or placement would be charged a fee

23 Coursera Case http://en.wikipedia.org/wiki/Coursera http://en.wikipedia.org/wiki/Coursera Coursera started in 2012 working with Stanford University, Princeton, the University of Michigan, and the University of Pennsylvania, – 12 partners were added in July 2012 – 17 more in September 2012 – another 29 partner universities in February 2013 – the current total number of partners is 108 In January 2014, the State Department told Coursera to block access to its courses for users in Cuba, Iran and Sudan Founded 2012 All courses offered by Coursera are "accessible for free“ Coursera courses: – approximate from six to ten weeks long – with one to two hours of video lectures a week – provide quizzes, weekly exercises, and sometimes a final project or exam Coursera reaches 839 courses in October 2014 Coursera reaches 10 million users in 114 institutions in October 2014 As of May, 2015, Coursera had more than 1000 courses from 119 institutions and 13 million users from 190 countries

24 Coursera Case http://en.wikipedia.org/wiki/Coursera http://en.wikipedia.org/wiki/Coursera Coursera: is a for-profit educational technology company List of ways to generate revenue, include: – verified certification fees – tutoring – sponsorships – tuition fees In January 2013, Coursera announced that the American Council on Education had approved five courses for college credit In May 2014, Antioch University announced that it was the first US institution to offer college credit for Coursera courses

25 Coursera: behind the scenes filming By Ben Loveridge (Learning Environments) http://blogs.unimelb.edu.au/researchservices/2012/12/15/coursera- behind-the-scenes-filming/ http://blogs.unimelb.edu.au/researchservices/2012/12/15/coursera- behind-the-scenes-filming/ Photo: Coursera filming set-up showing autocue and Wacom Cintiq 24HD Touch (Credit: Ben Loveridge)

26 General Preparation Notes for Filming Presentations (I) Content creation – video segments of around six minute long are the optimal length for student engagement Copyright – Use creative commons on flickr within your course to avoid expensive ongoing licensing – If you can’t find or create anything appropriate yourself, make sure any copyright in images or video has been cleared well in advance – Check out Astrid Bovell’s blog post on MOOC’s and the Copyright office Programs for presenting content – Keynote / Powerpoint / PDF – Video now lives in a 16:9 world so make sure your presentations are set to 16:9 mode in PowerPoint this is listed under the ‘page setup’ option in Keynote it is listed in the ‘inspector mode’ so something like 1920×1080 is a good start

27 General Preparation Notes for Filming Presentations (II) What to wear Avoid wearing green (clashes with the green screen) or fine striped or patterned outfits (can cause strange visual effects). Black and white clothing is not ideal Solid muted tones and colours are ok – not too dazzling or bright Avoid rattling jewellery Wear clothing that a lapel mic can easily attach Style of delivery Sitting or standing? Are they presenting together or separately? If standing then green screen or white background? (This affects if we use Screenflow vs recording to hard drive where picture is merged with background) If sitting will you annotate slides with the Wacom? Scripted with an auto cue, presenting from ‘notes view’ or off the top of the head? Creating slides on Mac or PC (affects if we use Keynote vs Powerpoint)

28 edX Case http://en.wikipedia.org/wiki/EdX https://www.edx.org http://en.wikipedia.org/wiki/EdX https://www.edx.org edX is a non-profit online initiative created by founding partners Harvard and MIT (in 2012) and runs on an open-source software platform (http://code.edx.org/)http://code.edx.org/ edX has more than 3 million users taking over 300 courses online (of 22 October 2014) Around 400 faculty and staff teaching courses and discussing topics online Around 100,000 certificates earned by edX students The source code can be found on GitHub Topics include: – biology, business, chemistry, computer science, economics, finance, electronics, engineering, food and nutrition, history, humanities, law, literature, math, medicine, music, philosophy, physics, science, statistics and more

29 edX Business Model https://www.edx.org https://www.edx.org With the exception of professional education courses, edX courses are free for everyone Some courses have a fee for verified certificates but are free to audit In September 2014 edX announced a high school initiative In October 2014 edX announced Professional Education courses In March 2015 it partnered with Microsoft In April 2015, edX partnered with Arizona State University to launch the Global Freshman Academy
