Hey there kiddo! Have you ever taken a test or quiz at school? Well, that's an example of educational measurement! Basically, it means figuring out how well you're doing in school.
Now, let's say you took a big test on a lot of stuff you learned in class. Your teacher wants to know how well you understood the material, so they'll use educational measurement to figure out your grade. They might use a grading scale, like an A, B, C, D, or F, or they might give you a score out of 100.
But it's not just about grades - teachers and schools also use educational measurement to figure out how well their teaching methods are working. If a lot of students do poorly on a test, the teacher might realize they need to change the way they're teaching the material.
There are lots of different types of educational measurement, like tests, quizzes, essays, and even observations of how well you participate in class. The most important thing is that it helps teachers and schools make sure students are learning and growing!
