ActivityShould We Remember Christopher Columbus as a Conqueror or Explorer?
Should Columbus' actions be viewed from a modern lens, or based on the values of his time? Mark Christensen shares two views on this question.

We believe the dialogic exchange between teachers and students allows students to explore their understandings and construct knowledge. The teacher, as the facilitator, encourages students to think deeply and justify their responses, and build on others’ ideas. This develops reasoning and communicative skills. Collaborative learning, in turn, emphasizes the interactions and dialogue between groups of students. Engagement in dialogic and collaborative learning exposures students to diverse perspectives and understandings. The ability to form cogent thoughts orally, share and discuss ideas, engage different perspectives, and successfully work cooperatively are essential skills in self-governance.
