One of my favourite learning web sites is GCFLearnFree.org which has numerous free online interactive learning opportunities for anyone who wants to improve their technology, literacy and math skills. I especially like their “Technology” section which has interactive learning tutorials and videos on most computer topics, including: computer basics, internet basics, email, social media, Facebook, Skype, Google, iPad, iPhone, all Microsoft Office products such as Excel, Word, Power Point, and Apple applications. This is an excellent web site for anyone who wants to brush up on certain aspects of their computer skills.
For more than a decade, the GCFLearnFree.org program has helped millions around the world learn the essential skills they need to live and work in the 21st century. From Microsoft Office and email to reading, math, money, job search, and more, GCFLearnFree.org offers 125 tutorials, including more than 1,100 lessons, videos, and interactives, completely free.
