Abstract: The teaching reform of ideological and political courses in universities has been sought after by college students and welcomed by young teachers due to the full intervention of big data technologies such as “smart classrooms.” The behavioral anomie of teaching communication and the “data man”’s catering and deconstruction of self-presentation. Habermas’s “Communicational Reason”’s criticism of technology rationalization provides a theoretical and practical basis for avoiding the rejection of big data technology by the “subject and object duality” structure-the construction of “discourse ethics” creates a good communication environment between teachers and students. Students’ emotional education can be realized in a rational context, and the reconstruction of the humanistic campus discovers the category of wisdom. In the future, only by being vigilant about education’s surrender to technology, clearly defining the bottom line of the integration of technology and education, and always aiming at stimulating the vitality of the subject, can the teaching reform of university ideological and political courses truly follow the essence of educational modernization and return to humanity. Modernize.
