Observation: The Use of PowerPoint as Teaching Media

 In teaching mathematics, there are a lot of teaching media that teacher can use, such as books, whiteboard, video, PowerPoint, mathematics application, etc. Teacher can choose teaching media that suits them and the material. In Sir Jordan’s case, he likes to use PowerPoint as his teaching media.

He organizes his PowerPoint well. Usually, his presentation starts with the final problem that we’ll solve. He introduces the final problem to draw the students’ intention. Then, he’ll teaches from the very basic part: introduction. He gives the definition, examples, theorem, and exercises. In some cases, he gives some examples to lead the student to the theorem, so the student will understand it better. After talking about the theorem, there will be some examples or exercises about the application of the theorem that have to be solved together.

Using PowerPoint during teaching

In solving the problems, Sir Jordan will lead the students. He gives them hint about the part they have to solve first. For example, when they learned about finding the measure in each angle in parallel and transversal lines. He pointed out some angles that had to be solved. He also liked to remind them about the definition and theorem. So, the students could solve the problems easier.

After solving some problems, he will give the final problem, the one that he shows in the start. As previous problems, he will lead the students to solve it together. As usual, he gives appreciation if they finish solving the final problem.

Not only PowerPoint, he also likes to use white board. He uses white board to show the steps when they’re solving a problem. He uses white board so the students will know the step and not jump to the conclusion only.

In using the white board, he always looks at the students while talking, and writes after he finished talking. He said that it’s not appropriate to talk when you facing the white board. Because you’re talking to the students, not the white board. It’ll feel like you teach the board, not the students. That’s why he always looking at his students while talking, and facing the board and writing after he finished talking. This is also an important note that I got from him and I’d like to implement it in my teaching.
