TU Delft Reaches 1 Million Enrollments on Courses on


RTEmagicC_one_million_enrollments_infographic3.jpg (1)

TU Delft, the largest and oldest public technological university in the Netherlands, announced this week that it has reached 1 million enrollments, with an average age of 29, in its 36 MOOCs in science, design and engineering since 2013.

  • MOOCs’ content is typically derived from classes given in TU Delft’s regular degree programs. At the university level, “these open courses have been used to enable students to attend the lectures online so classroom hours are dedicated to in-depth discussion of the course material, rather than to knowledge transfer”.
  • Some companies, such as Royal Haskoning DHV and Capgemini, have used the MOOCs internally as part of company training.
  • TU Delft has released MOOCs for children, too. The MOOC in Dutch “Scratch, programmeren voor kinderen (8+)” (Scratch, programming for kids (8+)), started on June 15, has attracted 2,500 kids.
  • “Solar Energy” by Arno Smets, TU Delft’s first MOOC, in 2013, has reached 130,000 enrollments and has been translated into Arabic on the Jordanian platform, with the goal to adopt solar energy as an energy source in the Middle East. The course teaches how to install a photovoltaic system using solar panels, and so contribute to the reduction of greenhouse gases to the atmosphere.

Anka Mulder, vice-president of TU Delft and the driving force behind the MOOCs at the university, has announced that for-credit MOOCs are next.

‘We are now working hard on the next step: ensuring that our students can earn credits for MOOCs of TU Delft, as well as for those from partner universities and vice versa. This means that they will gain access to a wide range of courses from top lecturers around the world. The challenge lies in agreeing on which courses we recognize and how many credits our students can earn in a certain phase of their degree program.’

The following are the course enrollments at Delft:

Numbers that Speak the Impact of Open Courses: the Scope of edX



Are MOOCs a failure?

Read this interesting thought from Dr. Joshua Kim, director of Digital Learning Initiatives al Dartmouth University, from Inside Higher Ed:

“Those of us participating in the open online education movement (…) never thought that MOOCs would disrupt higher ed.  We create open online courses because offering educational opportunities to the world’s learners is both aligned with our missions, and because we think that participating in this movement is a good way to learn about learning.”

And a good example of the success of the open education (or open courses) movement is edX. Dr. Joshua Kim is sharing these mind blowing numbers:

  • There are 8.3 million (unique) lifelong learners on the edX platform.
  • Between 2012, when edX started, and today – there have been 27 million course enrollments.
  • Over 1,000 courses have been offered.
  • There have been over 2,300 faculty and staff who have taught on edX.
  • Over 840,000 certificates have been earned by edX learners.
  • EdX has over 100 schools, institutes and organizations in the Consortium creating open online courses.

Who exactly are all these lifelong learners on the edX platform?

  • Seven-in-ten lifelong learners are 25 years old or older.
  • The median age of an edX learner is 29.
  • About 36 percent are women, and each year the proportion of women learners on the edX platform grows.  It will be interesting to see if the gender distribution for open online learning starts to match that for post-secondary education as a whole (~57%).
  • Over two-thirds have a bachelor degree or higher, with over a quarter having a masters. (And 4% having a PhD).

And where do edX’s lifelong learners come from?

  • There are lifelong learners in every country of the world (save North Korea).
  • A bit over a quarter (27%) of edX learners come from the U.S. The next biggest country is India (11%), the U.K. and Brazil (both 4%) and China, Canada, and Mexico (3% each).
  • Over four-in-ten edX learners live in emerging economy countries.

“Does Coursera, NovoEd, FutureLearn,, and other open online learning platforms report similar levels and trends?”,
wonders Dr. Kim.

A New Open edX Hosting Service for Testing or Small Instances

OpenCraft, an Open edX provider led by French developer Xavier Antoviaque, has announced the launch of an pre-installed service to host small Open edX instances, which “can be a good place for a first course experimentation with a small set of students; or as a side instance for tests,” according to his creator.

The service, hosted at, is now in beta mode and open to early testers.

Eucalyptus, the Open edX Platform's Next Version, Will Be Released on August (Updated)


The final version of Open edX “Eucalyptus” is scheduled to be released on August 10th.

This is the estimated release schedule, according to edX:

  • First release candidate (rc1): Wed, July 20th
  • Second release candidate (rc2): Wed, August 3rd
  • Finished Eucalyptus release: Wed, August 10th

Eucalyptus will be based on the code’s master branch of July 8, according to Ned Batchelder, an Open edX manager. The edX engineering team will put together Eucalyptus-related release notes, including the latest developments since Dogwood.

Update July 22: Eucalyptus RC1 has been finally released on Friday 22. See the announcement.

Microsoft Launches a Certification Program in Data Science on

Microsoft announced this week an online certification program, intended for professionals and graduates who are interested in Data Science. This program features several courses on Microsoft Excel, Power BI, R and Python languages, statistics and machine learning.

Available on as a free initiative with a verified certificate from $25 to $99, the Microsoft Data Science Curriculum outlines three units —Fundamentals, Core Data Science and Applied Data Science— and a capstone project requirement where “learners” showcase their acquired talents.

“At Microsoft, we believe the approach and tools used for learning need to continually evolve to meet the demands of our device-centric and data-driven world,” said Alison Cunard, the general manager at Microsoft Learning Experiences. She added that in the current era of technology, “both technical and functional skills are becoming increasingly critical across all careers and vocations.”






AdelaideX Open Learning Initiative in Australia Attracts 300K Enrollments


AdelaideX, the University of Adelaide in Australia’s initiative on, announced that it surpassed the milestone of 300,000 students since the program was launched two years ago. Students from 200 countries have enrolled in seven introductory-level MOOCs produced by the University.

“MOOCs are also leading us in new ways of using digital technologies to enhance our on-campus courses. In Australia, MOOCs have proven popular with hundreds of high school students and pre-university students, who are looking for ways to gauge whether a program is right for them,” said Dr Katy McDevitt, AdelaideX Program Manager.

Microsoft Surpasses One Million Enrollments on

ms openedx


Microsoft’s partnership with edX is working very well: over one million enrollments in one year in Microsoft courses.

This seems to be the most successful corporate example on, with the largest lead-generation deal in the MOOC universe.

“We were their first corporate member to offer MOOCs on their open, global platform and today, in a little more than one year, I am thrilled to announce that Microsoft just passed the threshold of 1 million enrollments in Microsoft courses on edX,” explained a Microsoft manager. “Reaching this milestone signals both significant interest from students and demonstrates the viability of using online channels to broaden the reach of quality education.”

So far Microsoft has created 75 courses on and they plan to produce more courses in the areas of cloud services,  mobile development and data science. The goal is “to meet  the demands of the device-centric, data-driven world we live in, where technology skills are becoming increasingly imperative across all careers and vocations,” explains Alison Cunard, from Microsoft Learning.

The Bureau of Labor Statistics predicts that by 2020 there will be 1.4 million new computer science jobs, with only 400,000 computer science students to fill them.

The Historical "Circuits and Electronics" Course Returns to

The historical “Circuits and Electronics” course, offered by edX CEO and MIT Professor Anant Agarwal, Piotr Mitros, Chief Scientist at edX and MIT Professor Gerry Sussman, has relaunched.

This course, originally released in September 2013, was the inaugural course on MITx and started the edX revolution. Today it’s taken by all MIT Electrical Engineering and Computer Science majors.

It is a self-paced course, with no weekly deadlines. Weekly coursework includes interactive video sequences, readings from the textbook, homework, online laboratories, and optional tutorials.

Many instructional designers –or we should say now “learning engineers”– took it as an example of how to build interactive sequences.

'Courses Need to Be Re-Engineered for the Digital Environment'

Beyond the traditional instructional designers, a new speciality is emerging: learning engineering. Courses need to be re-engineered to create online and blended experiences and improve learning outcomes.

This was one of the conclusions of the recent 2016 LINC Conference at MIT from Sanjay Sarma, vice president of open learning at MIT:

“Understanding how people learn is critical to understanding how — and when — to apply digital technologies for education. This is where “learning engineers” come in, designing new approaches to the practice of learning. Online education is not as simple as posting coursework on the internet; courses need to be re-engineered for the digital environment. By taking advantage of the available technologies, educators can create a blended learning experience, enhance the curriculum and, ultimately, improve outcomes for students.”
