What way can a teacher extend learning after students read about butterflies?

Assigning each student a type of butterfly to research is an effective way to extend learning after a class has read about butterflies. This approach encourages students to engage deeply with the subject matter by exploring various aspects of butterfly life, such as their anatomy, habitats, lifecycle, and the role they play in the ecosystem. Such research activities promote critical thinking and independent learning, as students seek information from different sources, compare data, and present their findings to the class. This not only reinforces what they have learned from the initial reading but also fosters a sense of ownership over their education and helps develop research skills that are valuable across different subject areas.

The other options, while they may contribute to understanding or retention, do not extend learning in the same meaningful and engaging manner. For example, repeating the text may reinforce familiar concepts but does not encourage deeper exploration or application of knowledge. Explaining difficult vocabulary may aid comprehension but is more about understanding the text rather than expanding on the subject. Reviewing text features helps in understanding how to navigate the material but lacks the depth of research and exploration that studying different types of butterflies offers.
