A Better Way: Part 1

Here's my vision for what colleges should do.

Use Virtual “Teachers”

Today, in most of the nation's 3,500 colleges, introductory courses, for example, Introduction to Biology, are taught primarily by an instructor, good, bad, or indifferent, lecturing to students umpteen rows away. You can often get a decent grade just by cramming for a midterm and a final, even though you'll have forgotten 3/4 of what you learned within days of semester's end.

Imagine that instead, you logged onto your home computer to find one of the nation's best biology instructors teaching Intro to Biology, using simulation and demonstration equipment far too expensive for most colleges to afford. You could replay any parts of the lecture you wanted, and at any point, you could click on words that would provide a fuller explanation of what the professor was saying.

After each 30-minute instructional unit, you would take an interactive quiz. You'd participate in simulations and other experiments online, using equipment for free that you couldn't possibly access in the real world. Even the classic frog dissection could be done online. Think of all the hassle, blood and gore that would be saved--not to mention the millions of frogs lives. Another benefit: the nation wrings its collective hands about the lack of minority instructors. Choose a minority instructor for the program and many thousands of students derive the benefits of having a minority biology instructor.

Using interactive teachers wouldn't completely replace the human instructor. Small classes and office hours would still be provided in person. But the large lecture, that boring vestige of the Middle Ages, so often blown-off by students who download lecture notes, would be replaced by interactive and virtual teachers, an approach that would enable every college student, rich or poor, to receive world-class education at a fraction of the cost.
