USE DUO IN MY ADULT SPANISH CLASS
THINKING OF A WAY TO USE DL AS A MOTIVATION TOOL IN MY WEEKLY ADULT SPANISH CLASS.
That's great, many classes are learning with Duolingo these days and, as far as I know, they had a terrific result. So, good luck. (Note: Please, avoid the upper cases.)
Introduce it to your students as a way to reinforce what they're using in your class :) They can practice at home, and return to you with questions over what they've learned.
