To effectively teach an English delay class for junior high school students, it's essential to engage with the learners and tailor the teaching methods to their specific needs. Here are some key points:

1. **Gauge Students' Understanding**: Start by assessing the students' current level of understanding in English through a quick quiz or discussion. This helps you identify any gaps or misconceptions that need addressing.

3. **Repetition and Practice**: Repetition is crucial for language learning. Incorporate plenty of practice exercises and drills to help students solidify new vocabulary, grammar structures, and pronunciation.

4. **Real-Life Contexts**: Use real-life contexts and scenarios to bring the language to life. This could include role-playing, discussions about current events, or engaging with authentic materials like songs, videos, or news articles.

6. **Positive Reinforcement**: Reward students for their efforts and progress with positive reinforcement. Acknowledge their achievements and provide encouragement to keep them motivated.

By following these strategies, you can create an effective and engaging learning environment that caters to the diverse needs of your junior high school English delay class.
