Hello Han! Thanks for your post. Open learning principles make academic resources more accessible, reducing barriers to knowledge and letting learners learn and apply what they gain in practical life to get good results educationally. Loved your example of how open learning helped students who might not otherwise have the ability to put their knowledge into practice. These are some of the innovations that educational videos are a part of, making learning complex concepts like Khan Academy easy to grasp. The change from traditional to digital platforms increased its reach and made it much more accessible, especially during pandemics. Thus, there are many opportunities for studying somewhere or anytime using videos and interactive simulations to improve your academic experience. To sum up, open learning with the support of electronic technologies enhances accessibility; flexibility; and efficiency in education.
