A teacher notices learners struggling with a concept. How can differentiated assessment address this?

The correct answer is B. offering varied assessment methods.

Explanation: Differentiated assessment allows teachers to tailor their evaluation methods to accommodate diverse learning styles and needs. By offering various assessment methods (such as projects, presentations, quizzes, or practical applications), teachers can provide students with multiple ways to demonstrate their understanding of the concept, thus helping those who may struggle with traditional testing formats. This approach promotes fairness and enhances learning by recognizing that students have different strengths.
