A third unique feature of technology as a teaching and learning approach is its ability to transform classrooms into highly collaborative spaces, where learning happens both in and out of classrooms. Technology facilitates interaction amongst students so that they can share questions and information while participating in relevant, real-world tasks prepared under the guidance of the teacher. As a result, technology changes teacher practices because the classroom is more student-centered. Students' roles change too from passive listener to collaborator and occasional expert. Furthermore, as tasks become more collaborative, they also become more complex, and students develop various transferable skills: "Technology-based projects often require students to undertake a larger workload that can also be different in nature-completing open-ended tasks, collaborating with others, directing their own learning, and assuming new leadership roles to name a few" (Groff and Mouza, 2008, p. 33). In technology-rich classrooms, students are more likely to be engaged in specialized group projects rather than whole class activities. People rarely work alone to accomplish important tasks in the world of work; technology is allowing schools to better reflect the collaborative nature of today's workplaces and perhaps better equip students with the skills they will need.
