Elfi lives in Deli Serdang North Sumatra. She teaches the third year students. That is why she no longer has class. She told me that she is going to observe her colleague. Do you have any experience of attending your colleague class? For your information during this semester I have a team-teaching class. We handle the class together. It is on Saturday s. So my colleague and I are in same class every meeting for the whole 2 periods. It’s nice you know. Before the class begins, we can share what we have in mind, what will we do with the class, then we discuss it. As the class is over, we have the reflection time.
