There are many reasons to try and learn new skills, like getting a headstart on a class you may be taking soon, or becoming more adept at new technology or even challenging yourself mentally to protect your brain from developing diseases like Alzheimer’s.
Check out this post on Inc.com of 5 places to educate yourself online (for free). The link includes the types of classes and many details of the different sites including a few descriptions of sample courses. It’s definitely worth going by for a lookie-loo. It has information and links to Coursera, Alison, Academic Earth, 99U and Udacity.
Surprisingly, Edx.org was not on this list. A few years ago we found edx.org and we were impressed with the variety of classes (technical, social, religious, for fun), schools (national and international partners listed here, including MIT, Harvard, University of Hong Kong, etc.) and types of courses (audit, certificate, just for fun) available. There are classes from TOEFL exam prep to Six Sigma to Supply Chain Management to the science of weight loss. There really are classes for everyone.
Another website we have used, which is *not* free, but has a free trial, is lynda.com. It has courses in business, technology and creative skills. We have watched some WordPress videos among others. It covers many skills that are currently useful in the workplace and would be a good place to update your skill set if you were changing vocations or re-entering workforce after a break.
Feel free to comment with any free sites that you have found helpful.
