I have an experiential theory (not proven -rigorously-) of learning-by-senses: students can learn to think better if encouraged to 'talk' (speak) more on topics of complexity. A aside note of this is that 'teachers often take control of learning when they feel the topic is complex; doing so hinder students' motivation for learning complexity themselves'.

Multilogues among teachers and students may be a better way for learning complexities.
