Here are a few important things to keep in mind when preparing and presenting your lessons, especially when they are on slides:
1. Font: Some children cannot read script. In addition, some fonts are harder to read than others. If the goal is to make content comprehensible, make your font as clear as possible. One less barrier.
2. Color-coding: Using different colors to make words stand out may help ELLs (and other visual learners).
3. Visuals: Where possible, use images, videos, or gifs to illustrate the content.
4. Wordiness: A slide that looks like an essay may include all of the information they need to know, but for some students it may cause them to shut down. Try to include only the essentials, or summarize using visuals. Or, if you really can't summarize, highlight key terms. Be aware of the words and phrases you use as well; idioms can cause confusion.
5. Videos: When watching a video, turn on the English subtitles, if possible.
I know you're all doing your best, and I commend you all. Just try to keep these tips in mind when you're preparing your next set of slides. Thank you!
