Which of the following is a differentiated teacher action?

Modeling and sharing with students is the correct choice because it actively engages learners in the process and shows them how to approach tasks, think critically, and solve problems. This technique allows teachers to tailor their instructional strategies to the varied needs of individual students, thereby promoting a deeper understanding of content. By modeling, teachers demonstrate the expectations for quality work and thought processes, which can be particularly beneficial for diverse learners who may require different approaches to grasp the material effectively.

In contrast, the other actions do not support differentiation or cater to individual student needs. Restricting student discussions can limit the opportunity for collaborative learning and sharing of diverse perspectives, which is essential in a differentiated classroom. Standardizing instruction for all negates the importance of addressing the unique learning styles and paces of students, leading to a one-size-fits-all approach that does not consider individual strengths or challenges. Ignoring individual student needs fundamentally undermines the principles of differentiated instruction and fails to promote an inclusive learning environment where all students can thrive.
