About Distance Education: Then and Now
Today, it’s possible to enroll in an online course at one of the hundreds of different online colleges and begin learning right along with on-campus students. Lectures can now be streamed live or recorded for later viewing. Likewise, class discussions and meetings with professors can occur over Zoom or other videoconferencing software. Students no longer have to be present physically in order to reap the benefits of college classes, even from prestigious universities. Cutting-edge technologies like machine learning, artificial intelligence, and virtual reality stand to further improve and transform distance learning in the future.
Free Online Courses Are for Everyone
Contrary to popular belief, online learning isn’t just for high school or college students. In fact, there are plenty of free courses for students, adults, and senior citizens. Some of these are free courses for credit, while others are simply free online classes for fun.
Types of Free Education for Adults
Not all online courses are offered through universities. Some are made available by corporations, while others are developed by individuals with a passion for a specific subject. Still, you’ll find that a good percentage of free courses for adults are indeed offered through colleges and universities, even highly prestigious universities such as Harvard, Yale, Princeton, and MIT, for example.
Benefits of Free Online College Courses for Adults
Aside from the prestige factor, there are several advantages of pursuing free online courses for adults that are offered through accredited colleges and top universities. For example, you’ll have the assurance that the content delivered through these free online college courses is legitimate. Often, these online classes are taught by the same professors who teach similar (if not identical) courses on campus. In many cases, they are tenured faculty members with advanced credentials in their respective fields, even PhDs.
Another benefit of free online learning from a college or university is the potential to earn credit for your work. Not all free online college courses for adults are associated with credit, though, and in many cases, you may have to pay a small fee to receive verification that you’ve successfully completed a course. In our ranking, these fees ranged from approximately $40-$200 per course. Still, this is a much more cost-effective alternative to traditional college enrollment. Credits earned from online college courses can often be applied toward a degree. Some online learning platforms even have entire degree programs that can be completed through low-cost distance education.
Free Online Courses for Adults Seeking Professional Development
Coursera alone has over a thousand free online courses devoted to professional development. These options span various skill levels, subjects, and skills. There are beginner-level classes on project management, as well as advanced classes on data engineering.

Similarly, edX offers free online courses for adults looking to upgrade their skills to align with the modern workplace. These courses follow trends and technological advancements in various fields and industries such as:
- business
- finance
- engineering
Like free online college courses for adults, these professional development classes are often free to audit but may come with an additional charge if you desire a certificate of completion or other verification that you’ve taken the course. Sometimes, an employer may require that you show proof that you’ve successfully met all course requirements, or you may want some sort of evidence of professional development to give you an edge when applying for a promotion or new role, for instance.
Free Online Courses for Personal Development
There are many free online learning opportunities that can boost our wellness, relationships, and other aspects of personal development.

Tips for Taking Free Online Courses
Below, you will find our editors’ tips for successfully navigating these online learning opportunities offered through some of the best universities in the country.
Choose Something that Motivates You
It’s crucial to practice discernment when choosing from the free online classes available to you. Whether you’re learning for school, work, or for yourself, it’s important to select a topic aligned with your interests or, at the very least, your goals. That way, when boredom sets in, or you just decide you’d rather do something else besides study, you can remind yourself why you enrolled in the class in the first place—and you’ll have a good reason!
Consider Paying a Little
It’s an unpopular opinion, but paying for an online class instead of auditing it for free can have some substantial benefits. For one, we tend not to value things as much when we get them for free, so paying a fee (even a small one) can make us appreciate the experience more. Moreover, forking over some dough for your otherwise free online learning experience may add something in the way of accountability. It’s like paying for a gym membership—you may be motivated to show up just because you know you’re on the hook financially. Some online courses have fees as low as $30, so you may find it worth your while to reach into your wallet as opposed to only considering free online courses for adults.
As we’ve mentioned, another advantage of paying for these courses is that doing so grants you access to a certificate of successful completion. These digital credentials can have real-world benefits in the form of college credit, employment opportunities, raises, and more. And even if you’re taking free online classes for fun or for personal growth, having a token of achievement can give you a self-esteem boost or motivate you to continue your online learning pursuits.
Use Tangible Tools and Resources
Turning your virtual studies into something physical may help you connect to them on a more meaningful level. It doesn’t have to be extreme. To get started, you may find that printing a chart or diagram so that you can hold it in your hand may be beneficial. Other strategies include ordering the print version of your online textbook, making hand-written notes, and adding assignments to your physical calendar. Remember, just because you’re taking free online courses doesn’t mean that everything needs to be digital.
