One of the best ways to ensure success in the classroom is to anticipate and identify potential trouble spots and concepts that students may have a hard time understanding, and prepare examples.
Examples help students understand difficult ideas through context, and being able to relate it back to experiences that they have had.
Preparing your own personal examples and experiences can have a number of extra benefits for your class. First, sharing your personal experiences can prompt students to share their own experiences as well and facilitate discussion. Second, it can help to build rapport. Sometimes students do not or cannot relate to foreign teachers. Sharing information about you can bridge this gap and show that their teacher is not an English teaching robot, but a human just like them. Lastly, sharing your stories to your students can increase student engagement and pacing in the class.
