I have teaching experience of 22 years. I explain my topics using power points slides. Once the topic is understood by my students I asked my students questions based on the topic I have taught them. I then give my students a worksheet based on the topic I have taught. I help my students in solving the worksheet. This gives me the opportunity to judge if my students were able to understand the topic I taught. I revise some of the points again based on my student work in the class. Then I ask my students if they have any questions based on the topic I taught, I then explain the areas of the topic in which students were struggling before ending the lesson.
