Educational big data today comes from many different sources and can be complex and difficult to manage. At the same time, it’s important to protect privacy and follow ethical standards when using this data. To tackle these challenges, this research has developed new, easy-to-use technologies. These include using crowdsourcing to bring together educational resources, connecting different learning environments in a meaningful way, sharing cloud-based educational tools, and ensuring strong privacy and data protection. Together, these efforts make it easier to combine and safely share data while respecting privacy and ethical guidelines.
