I find that student voice is critical in my classroom. It is impossible to teach students if there is no sharing, discussion of topics, exploration and discourse that helps everyone learn. Undoubtedly it is a key component in 21st century learning - student voice, the ability to voice their opinions. As teachers we also need to listen to our students, their needs, desires, opinions - we learn so much from them. Moreover, it helps students develop self- confidence, independence, and apply what they have learned to their lives.
Undoubtedly, it is better to let students express their needs and give them the opportunity to collaborate with peers both inside and outside their countries to block barriers among countries. You can watch and comment about some of our activities in our school.
