Which approach is primarily aimed at extending subjects for high-achieving students?

The approach that is primarily aimed at extending subjects for high-achieving students is enrichment. Enrichment involves providing additional learning opportunities that go beyond the standard curriculum. This method enhances students' educational experience by offering deeper insights, advanced materials, and opportunities for critical thinking and creativity in a subject area where they already excel. It allows high-achieving students to explore topics in more depth, engage with advanced content, or pursue special projects that align with their interests and abilities.

Supplementary activities could offer additional support or practice but are generally designed to reinforce the existing curriculum rather than extend it for advanced learners. Inclusion focuses on integrating students with disabilities into general education settings, ensuring that they have equal access to the same curriculum, but it does not specifically aim at extending subjects for high-achieving students. Differentiated instruction refers to tailoring teaching methods and resources to accommodate the diverse learning needs in a classroom but encompasses a broader approach rather than specifically targeting or extending the curriculum for high achievers.
