To improve your child's English proficiency in junior high school, consider the following strategies:

1. **Foster a positive attitude**: Encourage your child to see English as a fun and useful language, not just a subject they need to pass.

3. **Graded learning**: Start with simple vocabulary and grammar, gradually increasing the difficulty as your child's skills improve.

4. **Immersion**: Expose your child to English through movies, music, books, or even language exchange apps to practice speaking.

6. **Regular feedback**: Monitor your child's progress regularly and provide constructive feedback on their performance.

By implementing these methods, you can help your child build a strong foundation in English and improve their proficiency over time.
