What are the three main categories under which curriculum differentiation falls?

The correct answer, which identifies the three main categories of curriculum differentiation, is content, process, and product.

In curriculum differentiation, content refers to what students need to learn, the information or skills that are the focus of instruction. Process involves the methods and strategies used to teach the content and how students engage with it, allowing for varying approaches based on learners' needs. Product relates to the different ways students can demonstrate their understanding of the content, showing mastery through various forms of expression.

This framework allows educators to tailor instruction to meet the diverse needs of learners, enabling each student to engage with the material at their own level and through their preferred learning styles. This is essential in creating an inclusive classroom where all students have the opportunity to succeed. The other options provided, while they contain educational elements, do not encompass the core aspects of curriculum differentiation as effectively as content, process, and product do.
