A streamed classroom is an educational setting where students are separated into different classes or groups based on their academic performance or perceived ability. For example, students may be placed into basic, intermediate, or advanced mathematics classes depending on their level of proficiency.
Meanwhile, a mixed-ability classroom is an educational setting where students with different levels of academic ability, learning styles, and educational backgrounds are taught together in the same class. For example, high-performing students, average learners, and students who require additional academic support may all learn mathematics in one classroom under the same teacher.
