Mr. Siahaan

Teacher at Crown Technical College, loves mathematics

  • 🇮🇩 Surabaya, East Java, Indonesia
  • Crown Technical College
  • Since 2000
  • English, Indonesian
I teach mathematics at Crown Technical College in Surabaya since 2000. Most days I teach mixed-ability classes, and I never turn anyone away. Outside the classroom I'm learning the guitar. Inside it, I never turn anyone away.

More about Mr. Siahaan

If you were in my mixed-ability classes class, you probably remember the morning the power went out and we had class in the yard.
