For one week, I was being a teacher assistant at Senior high school in Menteng area, south jakarta. I have observed the class, made a lesson plan, helped the teacher to assess students exercise, and also taught students in the class. I did my observation in 1st grade class (X-5 class) and 3rd grade of social class (IPS-3 class) with the same teacher. I found many interesting thing when I observed the class. I have learned from the effective and ineffective learning in the class.

I want to share about the effective in the classroom learning. For the first, teacher taught the students with fun, not too serious. Sometimes, teacher gave some jokes to students. So, the students didn’t feel bored in the class and could feel enjoy the class. In the other hand, they could understand the material effectively. We know that fun is not always effective, but from the result of my observation, the teacher can teach with fun, but still focus on the material.

Secondly, teacher used lecture-discussion method for model of instruction. Teacher and students did lecturing and discussion. Teacher began with review previous work and student’s prior knowledge. It showed when the teacher asked students about the ABC formula to find roots of quadratic functions. Teacher makes students to remember about previous lesson. And then teacher gave explanation about the new material and also did question and answer with the students. And then teacher checked students understanding by gave some problems (exercises) and divided students into group that consists of 4-5 students for discussion. In the discussion, students can solve the problem together and also help each other. I think it was be effective because the classroom learning was not to be teacher centered learning, but students also to be more active in the class.

Thirdly, for the interesting and effective thing that I found is the teacher remembered all the names of students in class. The teacher said to me that it was very important because if I know and remember the name of all students, it means that we give respect and cares to them.

In the classroom learning, I found the ineffective too. I think the ineffective looked from the assessment when I helped the teacher to assess student’s exercises in group discussion. I asked the teacher how to assess it. The teacher asked me to give the absolute score. If the answer is true, we must give score 10 for each answered and If the answer is false, so we must give score 0. We didn’t assess how the students get the answer. I think it was not effective because we didn’t give appreciation for students understanding in the discussion. In addition, teacher only give exercises that not make students improve their higher order thinking.

If I had to teach the same lessons to the same student population, I will give the problems that can integrate student’s new and prior knowledge. So the students can improve their higher order thinking.
