Video can enhance a class presentation, provoke a spirited discussion, focus a student project, or provide content for an online course. How can a teacher, or his students, create those videos that enhance learning?
Teachers are focusing the light of the new technologies first on themselves, so that they might develop some new skills of their own. Then they proceed to refract and redirect the light of their own clusters of students, previously shining on trivia and trash, toward more serious and academic subjects.
Students attend school not simply to practice the technology techniques they already know, but to learn new modes of analysis and to see how they can use those familiar tools to dig deeper and see further. To grow in that way, they need to couple their technical facility with the guidance of a wise faculty.
