Educational Websites

Educational websites work best when you learn by doing, not by reading walls of text. This collection gathers interactive ones: each was picked by an editor, opened and checked live, and given a short review explaining what you'll learn and how.

Flexbox Froggy has you guide frogs onto lily pads by writing CSS, and before you know it, layout makes sense. Seeing Theory from Brown University lets you flip coins and drop balls to watch the rules of probability emerge before you ever see a formula. Bartosz Ciechanowski writes long, hands-on explainers on watches, bikes, GPS and sound, where every diagram is a 3D model you can spin and tweak. Learning Synths by Ableton teaches envelopes, oscillators and filters by ear, and Seeing Speech shows MRI and ultrasound footage of the tongue and lips as each sound of the phonetic alphabet is made.

These learning sites suit curious adults, students, and teachers looking for something to show a class. The list keeps growing as new finds are added regularly.
