Coursera /kərˈsɛrə/ is a venture-backed, for-profit, educational technology company that offers massive open online courses (MOOCs). Coursera works with universities and additional organisations to make a few of their courses available online, offering courses in subjects such as physics, engineering, humanities, medicine, biology, social sciences, mathematics, business, computer science, digital marketing, and data science, among others.

Business model

The current phase of business development is focused on user acquisition. Currently a few of the courses are available for free. A list of ways to generate revenue includes verified certification fees (started in 2012 as Signature Track), specialisation in areas of expertise. Other possibilities include introducing students to potential employers and recruiters (with student consent), tutoring, licensing, sponsorships and tuition fees. As of 2012 Coursera was reported to have 1.5 million students signed up for its programmes serving at 100 online courses. In September 2013, it announced it had earned $1 million in revenue through verified certificates that authenticate successful course completion. As of December 2013, the company had raised $85 million in venture capital. John Doerr suggested that people will pay for "valuable, premium services." Any revenue stream will be divided, with schools receiving a small percentage of revenue and twenty percent of gross profits.

In January 2013, Coursera announced that the American Council on Education had approved five courses for college credit. As the journalist Steve Kolowich noted, "whether colleges take the council's advice, however, is an open question." The courses that were recommended to degree-granting institutions for college credit are:

Coursera will offer proctored exams at the end of these courses through ProctorU, an online proctoring service that connects proctors and students via webcam. The service will cost $60–$90.

Coursera reduces the cost of courses it offers by using instant computer-based marking where appropriate, making students grade their peers' homework in a few cases, where computer-based marking can't be used, such as for poetry composition exercises and employing statistical methods to validate the assessment.

Coursera provides a Financial Aid programme that's designed for those who face significant economic hardships, so that those individuals with genuine needs might be given the chance to earn a Course Certificate at no cost.

Courses

Coursera offers all its courses "accessible for free"; a few courses have the option to pay a fee to join the "Signature Track". Students on the Signature Track receive verified certificates, appropriate for employment purposes. These students authenticate their course submissions by sending webcam photos and having their typing pattern analyzed.

Many specialisations are fee-based, but even these courses can be audited for free, with the restriction that one can't give the quizzes for that course. Courses such as "How To Create A Website In A Weekend" restrict the peer-review or collaboration function of the curriculum to students who have paid a required fee.

The website provides courses in a variety of areas, including humanities, medicine, biology, social sciences, mathematics, business, computer science, digital marketing and data science. Each course includes short video lectures on different topics and assignments to be submitted, usually on a weekly basis.

Coursera courses last approximately four to ten weeks, with one to two hours of video lectures a week. These courses provide quizzes, weekly exercises, peer-graded assignments, and at times a final project or exam. Courses are additionally provided on-demand, in which case users can take their time in completing the course with all of the material available at once. As of May 2015 Coursera offered 104 on-demand courses.

Coursera additionally offers "specializations" - sets of courses that help increase understanding of a certain topic. As of May 2015 the website listed 28 specializations.

Coursera and University of Illinois at Urbana-Champaign have partnered to offer a business degree that will be available to anyone. Students have options to register and complete business courses offered by University of Illinois on Coursera. This option is available in a free version (which lets the student watch the video lectures and do the assignments, without being graded) and a paid version (which includes the certification at the end of the course). In addition, students might register for University of Illinois iMBA programme to achieve fully accredited Masters in Business Administration. This iMBA degree would cost about $20,000, which is just a fraction of what the MBA degree costs at any additional top-ranked school in the United States of America. Coursera and University of Illinois iMBA websites give details and requirements.

Web forums are provided for courses, and a few students additionally arrange face-to-face study meet-ups using meetup.com, or online meetups. Notwithstanding the Coursera Honor Code prohibits copying answers, therefore the discussion shouldn't exchange answers but should practise healthy debate.

Coursera offers a mobile app for iOS and Android operating-systems.

Partners

Coursera started in 2012, working with Stanford University, Princeton University, the University of Michigan, and the University of Pennsylvania. Twelve partners (including Johns Hopkins University and Caltech) were added in July 2012, followed by 17 more in September 2012.

In late October 2013, Coursera teamed up with the United States Department of State to create learning hubs all over the world. In January 2014, the State Department told Coursera to block access to its courses from Iran, Sudan and Cuba.

On June 3, 2014, Coursera says it has been "working closely with governing authorities to navigate licences and permissions" and, as a result, "Iranian learners will now regain access to the majority of Coursera's courses".

In May 2014, Antioch University announced that it was the first US institution to offer college credit for Coursera courses. Antioch said it hoped the partnership would allow them to reduce student costs to complete a degree.

On September 17, 2014, Coursera was launched in Brazil, introducing Portuguese language course. It has tie-ups with big universities like University of Sao Paulo (USP) and State University of Campinas (UNICAMP).

Certificates

In 2013 Coursera began to sell certificates to participants.

Coursera's certificates are printable and can additionally be digitally linked to certain sites such as LinkedIn to show in the profile page of a Coursera course participant.

Since 2014, Coursera participants can earn Specializations in various disciplines for a fee. Successfully completing a collection of related courses entitles the participant to earn Specialization Certificates.

Keystroke biometrics

Analysis of keystroke dynamics throughout typing is used in combination with webcam images to confirm the identity of fee-paying "signature track" students throughout tests and quizzes.

IT infrastructure

Coursera runs the nginx web server on the Linux operating system on the Amazon Web Services platform with the primary stack in Scala on the Play framework. Data is stored in Amazon S3, and site search is handled by CloudSearch that indexes over 4.3 million documents on the site. Each month Coursera's database servers (running on RDS) answer 10 billion SQL queries, and Coursera serves around 500 TB of traffic per month. Coursera uses OAuth2 protocol for user authentication and LTI 1.1 protocol for interaction with courses.

Coursera API

Coursera has a set of APIs called Coursera App Platform, allowing third-parties to create apps and make them integrated with the Coursera functionality. Coursera App Platform is currently in beta. Now, there are a number of integrations available for third-parties.

  1. OAuth 2 API
  2. Learning Management Systems integration via LTI
  3. Catalog API, enabling third-parties to obtain the list of all courses, sessions, instructors and more
  4. Shibboleth/SAMLv2 for partner schools

Country restrictions

In January 2014, Coursera blocked their courses for users in Cuba, Iran and Sudan as a result of US sanctions to those countries. The company has made progress in restoring access to non-STEM courses in these countries.
