Utilitarianism in teaching

In Gert Biesta's book, The Beautiful Risk of Education, he takes a unique approach to discuss the theories of teaching and learning. He views teaching as a utilitarian pursuit. We can teach all of our students the same things, and some will excel, some will understand, and some may never understand, no matter how hard we try. In this, I think, he is probably correct. While I hope to make a connection and have an effect on every student I come into contact with, the reality is that I may not reach some students. I have high expectations for myself as a teacher and not reaching every student is something I will struggle with.

Biesta has some ideas that I really like. He espouses that we treat our students as "subjects of action and responsibility" instead of as passive objects. I value my students, so I agree with him that they should not be treated as objects. However, he also writes that constructivism is "the end of teaching." He argues that constructivism is a learning theory not a teaching theory, which takes away from the need for teachers. I'm torn because I see his points, but I also like the ideas behind things like constructivism. Perhaps if he weren't so negative in his writing he would be easier to agree with.
