Just give the foreign teacher keys to open the doors and a sign saying
"Chinese Staff STAY OUT" and the kids progress will skyrocket!

The teaching of ESL and EFL to adults has established a notable body of academic research and a variety of valuable practicum.

The teaching of a second language to children has not. This is critical because young children acquire language skills in a manner markedly different than adults.

The belief that placing the typical private language school FT in a room with children will generate "skyrocket progress" in second language acquisition is ludicrous. European elementary schools with professional teachers have been teaching multiple languages for decades, with less than 'stellar' results.

FTs are not the solution to inadequate language education in China.
