Ongkharak School is a secondary school in Ongkharak, Nakhon Nayok. I observed there fifteen days. I had opportunities to teach mostly 7th-grade students. What I have learned is a teacher should show her enthusiasm in her teaching so that students can feel the same way. Moreover, no matter how old students are, they are humans who like engaging lessons with some fun. Games and group activities are better ways to teach them rather than lectures only.
