Which groundbreaking mathematical learning platform first implemented real-time 'knowledge mapping' using big data to create personalized learning pathways for each student?

Big data is transforming how mathematics is taught and learned across educational platforms. Modern analytics tools can track student problem-solving patterns, identify common misconception points, and even predict which mathematical concepts a student might struggle with next. This has led to the development of adaptive learning systems that have dramatically changed the educational technology landscape. Test your knowledge about how big data analytics is revolutionizing mathematics education!
