The Khan Academy is one of the biggest learning resources available on the internet, with a huge range of different course formats. One format that can have particular educational benefits is video, as it allows the overlay of voice and visual to make ideas easier to comprehend and get a visual idea of abstract concepts such as maths and science. The Khan Academy Youtube channel has a number of such videos, as well as a few other clips of interest. According to view count, these are the most popular:
1. Salman Khan’s TED Talk. TED Talks are another great source of free online learning, allowing experts from all walks of life to explain something they’re passionate about. In this case the founder of the Khan academy discusses its importance and how it came to take its current form.
2. Basic Addition. It’s a skill we all take for granted, but basic addition can be more challenging than it needs to be. There are many ways to make it easier on yourself and think about it logically and concisely, some of which are covered in this video.
3. Simple Equations. In the same vein, a number of basic mathematical equations can be difficult for some, especially if it’s been a while since you were at school. A visual chalkboard makes it easy to follow how they work and how best you can get your head around them.
4. SOPA and PIPA. If you pay attention to internet news, you may have heard these acronyms a lot in recent months. They both refer to bills before the US congress that seek to place restrictions on the internet, such as forcing IPs to deny service to certain websites, or throttling speeds back for some. This has caused enormous outcry, for many of the reasons outlined in this video.
5. Krebs/Citric Acid Cycle. Like maths, science is another area that can be difficult to understand when read solely from a textbook. These visual diagrams will help you understand the citric acid cycle in a way that is clear and concise.
Videos are a great way to learn as they give you something visual to focus on, but be aware of not just sitting back and letting it all happen. Try to take an active approach and make notes as you watch, to fully ensure the knowledge is going in.
