I start off the class by greeting students and asking how they are doing. I do this to get the vibe going and make students feel comfortable. Then, I ask some easy questions to get the class started and get students thinking about the material to day. I would ask, "Have you ever been to a supermarket? Are the items there arranged by category?"  and "What's the function it?" These questions get them thinking about in the real world applications of what they' are about to learn, like how supermarkets sort items by category. It's a way to help them relate the classification material to their everyday lives.

      I use technology during my teaching demonstration to get students involved. For example, I show videos about vertebrates animals and introduce some of the endemic animals from Indonesia. This makes students more interested in the material and helps them learn better. In the group discussions I guide, I make sure they are paying attention or no. I also use digital games during evaluations to make class more fun. The students who win the games get gift and get appreciation.
