At present, there are many training institutions on the market to cultivate children's oral expression, but the market is mixed, so parents need to carefully identify and choose suitable and reliable institutions.
I recommend the Super Speaker School for Teenagers, which is jointly founded by the Super Speaker column and the Communication University of China. It has scientific and reasonable training methods and 8 years of practical experience, and has trained countless children. Everyone knows the program Super Speaker, and most people's knowledge of speech eloquence comes from this program. Now there are branches all over the country. If you really need to cultivate your child's expressive ability, you can consult your local branch school.
