Children are unwilling to learn English. This is a headache for most parents. In fact, my child was unwilling to learn English before. Here is how I solved it. I hope it will be helpful to you:

First of all, change your own point of view. Don’t let your children learn English just to improve their grades. You must really make your children like English

Help your children find English training classes. Don’t just go to places that are just for improving their grades. Only teaching papers and exercises, so that no one is willing to study

You can try to send your children to places that can really improve their English speaking and English application skills (I took my children to OKF English at the time, They don't teach textbooks and papers at all, they just improve the practical application ability of English through foreign teacher courses and other courses) so that children can feel the fun of learning English so that they can continue to learn English better

Accompany Children learn English and grow together, so that they can be more motivated
