The Top 10 Free Online Learning Platforms and the 15 Most Popular Free Online College Courses They Offer

Not everyone interested in learning online takes distance learning courses with the ambition of earning a degree, or even a certificate/diploma. Some students appreciate learning for the sake of learning. In fact, during the pandemic, learning for learning’s sake exploded amid adults seeking intellectual stimulation while stuck at home. Much of this virus-induced studying took place via online platforms offering MOOCs—massive open online courses. In this article, we’ll investigate the top ten free (or almost free) online learning platforms and the fifteen most popular free online college courses.

Top 10 Free Online Learning Platforms

Free online learning platforms have unique features and offerings, so much so that they are difficult if not impossible to rank alongside one another. In terms of popularity, Coursera and edX are clearly leading the pack. When it comes to quality and affordability, though, the platforms are comparable. Choosing the best place to learn online is really an individual choice that necessitates a close examination of one’s own preference and learning style. Thus, we’ve listed our picks for the top 10 free online learning platforms in random order:

Coursera

Website

Founded in 2012, Coursera is a free online learning platform designed to expand access to education to people around the world. Today, the site offers hundreds of free online college courses from more than 200 different accredited universities, including top colleges like Duke, Yale, University of Michigan, Arizona State University, and many more. So many free online college courses are available through Coursera that it’s even possible to earn an entire degree on the platform!

Coursera isn’t just large, though; it’s also extremely diverse. The platform features numerous learning pathways, including online college courses for credit, free online college courses for senior citizens, and free courses online with certificates, for example.  

edX

Website

An online learning platform similar to Coursera, edX was even founded in the same year (i.e., 2012). Beginning with a single course from MIT, the platform would eventually grow to encompass thousands of free online courses hosted by over 150 different member institutions. Standout providers include the University of California- Berkeley, Harvard, Boston University, and the University of Texas system. With edX, students can work towards a degree with free online college courses for credit or take a course purely for personal development. Likewise, career-oriented learners can choose to take free online college courses with certificates for professional development and career advancement.

Khan Academy

Website

Unlike Coursera or edX, Khan Academy is a free online learning platform that caters to younger students. In addition to PreK-12 classes, the site also offers free online college courses for high school students, including AP Biology, AP Calculus, AP US History, and more. Though academics are the focus, Khan also offers “life skills” courses in categories such as careers, personal finance, college admissions, and entrepreneurship, for example.

MIT Open Courseware

Website

Best for those looking for free online college courses for adults without all of the bells and whistles, MIT Open Courseware is a large repository of MIT’s course material that is free and accessible to learners around the world. There is no fee or registration required to use MIT Open Courseware, but there is also no learner support like the kind you will find with more structured online learning platforms like Coursera or edX, for example. Learning is truly self-paced, and all materials for a particular course may not be available, depending on the instructor’s discretion. Still, this is an incredible resource for individuals seeking truly free online college courses for purely intellectual purposes. No degrees or certificates are issued through MIT Open Courseware.

Open Learning Initiative (OLI)

Website

Operated by Carnegie Mellon University, the Open Learning Initiative—or OLI—is a resource for the university’s students as well as independent learners. Similar to MIT Open Courseware, OLI offers bare-bones free online college courses. This means students will have access to course materials, but there are no instructors or free online learning resources/support. Course offerings span disciplines such as arts and humanities, life sciences, computer science and programming, mathematics and logic, data science, and more.

FutureLearn         

Website

FutureLearn was founded in 2013. Since then, the free online learning platform has formed partnerships with leading colleges and universities across the globe. These partner schools include reputable U.S. institutions of higher learning such as the University of California-Irvine, University of Colorado, Johns Hopkins University, Penn State University, and the University of Michigan, for example. Like most other e-learning sites, FutureLearn offers both free online college courses as well as premium options, including certificates and even degrees. FutureLearn has been criticized for being a little behind the times in terms of its interface and lack of mobile features. However, if you’re willing to dig a little and learn on your PC versus your Smartphone, there are some good, free online learning opportunities to be had here.

Stanford Online

Website

The opportunity to study at one of the most prestigious universities in the world at absolutely no cost and without rigorous admissions requirements doesn’t usually come along every day. With Stanford Online, it does, though. There is a bit of a catch, however. The free online college courses available from this accredited university are not-for-credit classes. They can’t be transferred or count towards a degree program. Still, these free online college courses for adults looking for professional or personal development alone will find some quality offerings here. Classes span subjects such as engineering, education, health and medicine, and arts and humanities.

Harvard University Online

Website

Harvard University - Free Online College Courses

While it may seem too good to be true, it is actually possible to take free online college courses from the distinguished Harvard University. In fact, there are currently over 100 free online learning opportunities available through the school’s online division, spanning topics such as computer science, humanities, social sciences, business, and more. In addition to these free online college courses, the university also offers nearly twice as many paid courses, many of them extremely affordable. These paid classes are usually associated with some sort of credential such as a certificate of completion.

Udacity

Website

While it doesn’t exactly offer free online college courses, Udacity does extend free online learning opportunities for individuals with career advancement aspirations, particularly in the field of technology. While the platform’s scholarships enable some eligible students to study topics such as machine learning, artificial intelligence, and cybersecurity at no cost, it’s important to note that students who do not receive financial aid will be responsible for fees associated with Udacity’s course offerings. Still, payment plans and discounts are available. Though not affiliated with any college or university, Udacity does offer its own signature credentials in the form of “nanodegrees.”

OpenLearn

Website

Affiliated with The Open University, a UK school, OpenLearn offers open access to its catalog of approximately one thousand free online college courses. These offerings span difficulty levels from introductory to advanced as well as academic disciplines including business, psychology, education, politics, and technology, for example. While there are no formal credentials awarded for these free online learning opportunities, certificates of participation along with digital badges are available.

The Rise of E-Learning

Online education, once little more than a pipedream, is now big business. According to industry research, the market for distance learning has already surpassed $250 billion and is expected to expand by another 21% by 2027. The popularity of distance education cannot be denied. As the popularity of online education grows, so too does the accessibility of online courses. Advancements in distance education technology have made it possible for learners all over the world to access information that was once out of their reach. The wide availability of free online college courses has implications for all types of learners, not just those with degree aspirations.

Types of Free Online College Courses

There are various types of free online college courses students can enroll in. Below, we’ll briefly discuss some of the common kinds of free online courses, including:

  • Free Online College Courses for High School Students
  • Free Online College Courses for Credit
  • Free Online College Courses for Senior Citizens
  • Free Courses Online with Certificates

Free Online College Courses for High School Students

Is it possible to take advantage of free online college courses even before graduating high school? In some cases, the answer is yes. Qualified high school students may be eligible to enroll in online dual credit or dual enrollment classes, which allow high school students to earn credit for both high school and college simultaneously. Free online college courses for high school students can also help prepare a student for the rigors of college without all of the risk. By taking introductory college courses online, high school students can get a feel for postsecondary academics and explore possible majors prior to actual enrollment at a college or university.

Free Online College Courses for Credit

While it’s a bit more difficult to find free online college courses for credit, it’s not impossible. Most of the free online learning opportunities you’ll find on platforms like Coursera and edX, for example, can be audited at no cost, but to earn any sort of credit, there is a fee. Still, financial aid is often available, which can cover most or all of the costs for students with limited financial resources.

Free Online College Courses for Senior Citizens

Senior citizens are in a unique position when it comes to accessing free online college courses. In the United States, seniors are granted discounted or free tuition from most colleges and universities, so students of a certain age can take advantage of the school’s online courses at substantial savings. Still, not all of these opportunities will result in credit, so it’s best to check the fine print. If you’re not looking to earn a degree in your golden years, though, taking non-credit free online college courses can have other advantages, such as helping you maintain cognitive function or teaching you a new skill or hobby.

Free Courses Online with Certificates

Finding free online courses with certificates is a bit like finding free online college courses for credit. While it’s not impossible, it’s also not the norm. Typically, students can find plenty of courses online to audit at no charge, but when it comes to earning a certificate of completion, there is usually a nominal fee. Still, financial aid is sometimes available to cover the costs of these certificates, depending on the platform as well as student need/eligibility. Earning a certificate of completion can provide proof that you’ve fulfilled the requirements of free online courses, which can help you earn academic credit or professional advancement, for example.

Advantages of Free Online College Courses

It’s not every day you see the words “free” and “college” in the same sentence. Add the term “online” to the mix, and you’ve got a situation that seems almost too good to be true. The technological advancements in distance learning that have led us to this new reality have certainly made it a good time to be alive, especially for those who value intellectual pursuits and lifelong learning. Aside from the cost savings associated with free online college courses, there are a ton of other benefits to be reaped from these incredible online learning resources.

Free College Credit

To begin with the most evident benefit of free online college courses, we’ll state the obvious: earning college credit at zero tuition cost is, undeniably, the biggest draw that the e-learning industry offers students. Aside from receiving a scholarship or grant, there are few other options for students who hope to earn a college degree without amassing loads of student debt. Enter free online college courses for credit. These distance learning options have the potential to be a game-changer for students who want to transfer credits to the college or university they plan to attend, saving both time and money towards their degree. Beware, though, not all e-learning classes meet the criteria for a credit award. In fact, free online college courses for credit represent only a small percentage of the free online learning options available.

Flexible Learning Modes

Whether you’re a college student or a nontraditional learner, another advantage of free online college courses you’ll enjoy is the ability to learn at your own pace. Even when education is a priority, it’s sometimes difficult to fit classes into a busy schedule. E-learning helps alleviate this common issue for students by eliminating the commute and freeing up time for other responsibilities and activities. With free online courses, you can usually learn at any time of day or night and any place where you can access the Internet. For some learners, this flexibility makes taking classes easier; for others, it makes it possible.

A note of forewarning, though—not all free online college courses are alike, and some have more stringent requirements than others. If you’re enrolled in a synchronous class, for instance, you may be required to log in to the class at a specific time to view an interactive lecture or participate in a class discussion. Be sure to review all of the attendance requirements prior to enrollment.

Professional and Career Development

You might think free online college courses are just for students seeking a degree, but you’d be wrong. The reality is that many professional and working adults seek out free online learning opportunities as a way to build their skills and remain competitive in their particular industry. If you think about it, e-learning in the form of free online college courses is the perfect conduit for professional development due to its convenience and flexibility. The availability of free online courses for adults means that you can study in your pajamas, and you don’t have to take time off from the office to complete your classes. Win-win!

Resources for English Language Learners

You may have noticed that some of the most popular free online college courses are geared towards non-native English speakers. These classes can help prepare English language learners for their academic and professional pursuits in the United States. Some of these courses are specifically designed to help students pass English proficiency tests like those required by colleges and universities. Other classes help students improve their pronunciation or emphasize language usage in the workplace, for example. Some of the English as a Second Language (ESL) classes that can be classified as free online learning opportunities include:

  • Preparing to Network in English (University of Washington)
  • How to Write an Essay (University of California- Berkeley
  • Write Professional Emails in English (Georgia Tech)
  • The Music of American English Pronunciation (University of California- Irvine)

These are just a few examples of the many online courses available right now for ESL learners.

Lifelong Learning

Many people associate learning with an end goal such as academic achievement or career advancement, for instance. While there’s certainly nothing wrong with learning for a purpose, learning has an inherent value as well. That’s why there are a variety of free online learning opportunities available for students who want to take classes for pure enjoyment. Sometimes these classes are promoted as free online college courses for senior citizens, but anyone can take them.  For decades, universities have given older students the opportunity to audit courses for free, and some even offer free tuition for retirees. Online college courses for senior citizens make these affordable learning options even more accessible. Now, seniors with health conditions that affect their mobility can take free online courses from home, eliminating any physical barriers to learning.

Disadvantages of Free Online College Courses

Nothing is perfect, not even free online learning. Before you invest your time in the pursuit of knowledge via free online college courses, you’ll want to be well-informed of any potential drawbacks.

Low Attrition Rates

One of the biggest disadvantages of free online college courses is their low attrition rates. This just means that a large percentage of online learners never finish the classes they start, especially if these classes are free. Human psychology dictates that when we don’t pay for things, we tend to value them less. It’s not rational, but apparently, it’s the reality. Our advice? Before clicking the “enroll” button, do a quick cost-benefit analysis, and then commit!

The Engagement Factor

A well-documented problem with online classes of any kind is their inability to engage students. If you thrive on face-to-face interaction with classmates and instructors, you could find yourself struggling once enrolled in free online college courses. The situation may be particularly challenging with asynchronous courses that enable students to work primarily at their own pace, requiring no specific log-in times. With this mode of content delivery, students may never cross virtual paths, which could lead to a sense of alienation from the classroom environment. We advise taking advantage of any interactive features your free online learning platform provides. Think chat features, virtual office hours, or Zoom conferences.

Hefty Self-Discipline Requirement

While many students enjoy the autonomy afforded to them in an online learning environment, others struggle to find the self-motivation and discipline to stay on track. With no set schedule and a lack of oversight from professors, students may have a hard time sticking to self-imposed deadlines. Students enrolled in free online college courses for credit may have less trouble, but without a specific goal to work towards, self-discipline may peter out quickly. If you anticipate problems in this area, try writing out your assignments on an actual calendar, or set alarms for your assignment deadlines via your smartphone.
