Episode notes
Conversation Trumps Passive Exposure
- Children learn words by hearing humans converse, not from screens or passive exposure.
- Ariel Kalil emphasizes conversation as the most effective vehicle for early vocabulary growth.
Early Gaps Persist Through Schooling
- Large gaps in language and cognitive skills by socioeconomic background appear very early and persist.
- School rarely closes these gaps, so pre-kindergarten home inputs matter most.
Don't Just Send Books — Make Reading Easy
- Avoid assuming lack of books is the core problem; parents often don't read what they already have.
- Provide engaging, convenient access like a digital library to increase actual reading time.
