Which of the following best defines differentiated instruction?

Differentiated instruction is best defined as a teaching approach that is specifically adapted to meet individual student needs. This approach recognizes that students differ in their readiness, interests, and learning profiles, and therefore, instruction must be tailored to support diverse learners effectively. By providing various avenues for students to engage with content, demonstrate their understanding, and show what they have learned, differentiated instruction aims to optimize student engagement and achievement.

This method ensures that all students, regardless of their starting point, are challenged and supported in their learning journey. It may involve varying the content, process, products, or learning environment based on each student's unique requirements. This approach contrasts sharply with a one-size-fits-all teaching method, which does not account for individual differences, and instead promotes uniformity among students, potentially neglecting the needs of those who may require additional support or challenges.

In summary, the essence of differentiated instruction lies in its flexibility and responsiveness to the diverse needs of students, making option B the most accurate definition.
