Affective filter is like a gate in your brain that decides whether or not you want to learn something. When you are feeling happy, excited, and comfortable, the gate is open and you are more likely to learn and remember things easily. But when you are feeling anxious, bored, or stressed, the gate closes and it becomes harder for you to focus and understand what you are learning.
Think of it like watching your favorite TV show. When you are relaxed and happy, you enjoy it and remember what happened. But if you are upset or worried about something, you may watch the same show but not remember anything because your brain was too busy thinking about other things.
So, it is important to keep your affective filter open when you are learning something so that you can learn and understand things easily. Teachers do everything in their power to make sure their students' affective filter is open by creating a positive and safe learning environment, making learning fun with games and activities, and praising their students when they do a good job.
