What educational tool provides content flexible for differentiating instruction?

The correct answer is an intervention program, as this type of educational tool is specifically designed to provide tailored support to meet the diverse needs of students at different levels of learning. Intervention programs often include various instructional strategies and resources that help educators differentiate instruction effectively. They focus on identifying students who may be struggling and providing targeted assistance to help them catch up or enhance their understanding of the material.

In practice, intervention programs offer flexible content that can be adjusted based on a student's specific needs, allowing teachers to modify approaches, pacing, and materials accordingly. This means that if a student excels in certain areas but needs more support in others, the intervention program can be adapted to maximize their learning potential.

While assessment programs, review programs, and enrichment programs have their own purposes, they do not primarily focus on providing adaptable content aimed at differentiation. Assessment programs are often used to measure student progress, review programs focus on revisiting previously learned material, and enrichment programs typically offer advanced content for students who are ready for more challenging work. Each of these tools plays a role in education but does not center on the same level of flexibility for differentiating instruction as intervention programs do.
