You can have conversational learning only when students have a factual basis to draw on. The concept works for people who have learned the basics of their subject, but most students, even on a college level, are decidedly lacking in basic knowledge and basic skills. K-12 is simply not preparing many, many students properly, for a variety of reasons. Reading levels are considered "adequate" if they reach 6th grade level. Ditto writing capabilities. Yes, many students exceed those levels, but many do not. Without a knowledge base, conversational learning is simply not viable.
