Under UDL and CBL, learners have the opportunity to control the lesson, how it is understood, and the products created. CBL is a great means to encourage recognition, the use of strategy, and the demonstration of affect. At the end of this lesson, if students demonstrate a deeper understanding of perspective, whether through clearer focus, more discernment, or a wider viewpoint, this lesson will be successful.
