Cloud learning provides an online classroom environment that allows for collaboration between different learners from various locations. It can be used by providing students technology and questions to spark collaboration, with benefits including constant access to education, environmental friendliness, variety in learning, and low pricing. However, there are also potential downsides like network problems and risk of lost information. Studies show that when given access to computers without a teacher, children can learn challenging subjects through self-organization, encouragement, and collaboration.
