EduCode™ makes coding and computer science education accessible for kids of all learning styles and backgrounds, on a large scale, without the need for guidance from a teacher. Self-directed courses empower kids to learn coding independently. EduCode's key difference resides in our video micro-lessons, which break down complex computer science concepts into fun and engaging exercises. Rich storylines provide context and motivation throughout the learning journey.
