Students learnt about "Teen Violence". First, Mr. Somchai introduced the lesson through PowerPoint Presentation after the reading of vocabularies. He explained the concepts by giving lots of examples. As the lesson progressed, students gave their own opinions on how to avoid teen violence at home and outside their homes. They were able to cite situations to their classmates. Then, they answered questions both in written and verbal to check their understanding. The class activities went well. Students participated actively.
