Key ideas behind mindfulness is that it is the antithesis of memorization and education focused on memorization stifles creativity. Learning mindfulness seems like learning a combination of critical thinking skills and how to question authority. And I agree- students should be taught these skills. Students should be taught about bias and perspective. At the college level, these ideas should be taught in first-semester courses. In middle and high school, these ideas should be introduced when discussing history, science, and literature.
However, not all courses can or should consist purely of questioning facts. Most careers require learning linguistic cornerstones (aka memorization of terms). You cannot begin to debate the nuances of a topic unless you are able to read and understand previous work on a topic and know the language of the debate.
Learning terms should not just include memorization of the words that describe the terms but understanding the concepts behind them. Part of this process of memorization is mindfulness- students should be engaged in thinking about how these terms fit together and how they fit into the broader topic. When we discuss learning techniques with students, we should be emphasizing that learning requires the hard work of memorization and simultaneously making mindful connections.
