My lesson ''Interference of the light'' in Kauriala high school.

 20.03.2014

On Thursday I and Aigerim were in Kauriala high school to observe the Physics lesson. And last week I arranged  with teacher of physics Paula to lead one of the part of lesson in Physics in English (20-30 min). She was very nice to me and gave  topic. It was a topic ''Interference of the light''. I was prepared carefully for the lesson, had  prepared presentation. It was really my first lesson in English. Firstly, when the lesson started, Paula asked homework from students and checked the answer and also on the overhead projector showed solution of these tasks. It was good decision and also she kept time. She gave the solution of tasks to each student. Of course the lesson was in Finnish.

Secondly she introduced me and after that  I continued the lesson in English. In order to organise group work I gave for students puzzles (cards) from which they should collect five pictures. The students who collected  the common picture were combined into one group. Then they should discuss it in groups and answer the following questions: what did you see on this picture? In what was the reason the differences of colour on these pictures? I gave them 3 minutes for discussion and then they should were briefly present their  answers.

Before that the students never have had  lesson of physics in English. They were pleasant surprised. They tried to explain the pictures and each student gave own opinion about it. However, some students did not give any ideas. From my point of view it depends from their English levels.

Thirdly, we had discussed about these tasks and I told them this phenomenon called interference of light. So we discovered today's topic, after that I considered  interference of the light. At the end of my presentation I showed the video which helped for students to understood  the topic deeply.

Next Paula continued the lesson, she explained the next topic ''Diffraction of the light". Her lesson was usual. To show phenomenon of  diffraction on the lesson teacher has used equipment the laser.

I have gave the students a sticker for feedback. They wrote me what did they think about this lesson, did they understand this topic and my english, what did they have expected from this lesson? At the end of the lesson the students stuck the sticker on the blackboard. Feedback  of the students are showed below.

 In my opinion I spent a good lesson. I was satisfied although it would be much better. The comments were useful and some students didn't understand me, I think their English level were not so good. They didn't understand some terms of physics in English. After lesson Paula gave me feedback about my lesson. She said that my English level better than hers. She said it was a good lesson. Her liked, how I divided students on groups and how the students worked actively and  my explanation as well.
