Native-language instruction means that you learn things in the language that you are familiar with and comfortable with (your first language). For example, if you speak Spanish at home, you might learn math or science in Spanish at school. This can be helpful because it allows you to better understand the concepts being taught and it can also help you feel more confident and comfortable in your learning environment. It's like having a friend who speaks the same language as you and can help explain things if you don't understand them. Overall, native-language instruction can make learning easier and more enjoyable for students.
