The video is accompanied with a support booklet with vocabulary drills and the script in English, Korean, and the English phoenetic of Korean so parents can follow along and get involved in the teaching process. Every Language Tree video embeds our unique Multi-Cognition Approach?, developed by a cognitive scientist from Stanford University, which stresses three proven learning techniques: 1) repetition, 2) deep thinking, and 3) information clustering. The net result is that your child will be able to learn more phrases, more quickly, and better retain what was taught.
