I have heard of several buxibans catering for kids’s Spanish learning, and I know at least of one in Chongshiao, one in Neihu. Most kids are Taiwanese, but their parents have lived abroad/want to move abroad.
I’ll talk to the people and see if I can post a few addresses for anyone who’s interested.
Most people go for tutors, but classes keep kids motivated as a group. They make new friends and have fun.
I wish I could help more on a subject like this given my background (parent from Venezuela, raised in Miami). Sadly Spanish just wasn’t important enough for my father to teach me… ::sigh::
Start at the universities. They have Spanish classes and they have native Spanish speaking students in their Chinese classes that might be interested in tutoring.
