Oh, the wonders of technology, particularly in teaching and learning. Consider all the ways in which machines have improved the delivery of education:
Yes, machine teaching has transformed the way learning is delivered to students, and as technology continues to evolve, the ability for students to interact and engage as they learn will only improve. Indeed, some are predicting full virtual classrooms without teachers at all – just “supervisors” who ensure student compliance and focus and who resolve technology issues as they arise.
As far as technology has moved education, it has not yet replaced the physical presence of teachers and instructors. To understand this is to understand the human psyche.
Science and Art
Teaching is a science and an art. What machine learning contributes improves the science of education in phenomenal ways. Students are exposed to grand experiences and learning activities and to a virtual world that will only get better. Teachers, however, supply the art. They are the actors and actresses that instill a love of learning, that promote personal relationships with their students so that they want to set goals and excel in learning and so that they receive the human praise and love they need. Maybe someday, a holographic image may come from the screen and give a child a hug, a pat on the shoulder, and the encouragement s/he needs to move forward. Until then, the teacher is a prime factor in the educational experience.
