Virtual Classrooms and Virtual Choices

Posted January 25, 2011 8:30 AM by Steve Melito

When does a classroom have too many computers? When it has too few teachers.

That's the complaint in Florida, where over 7000 students in the Miami-Dade County Public Schools are enrolled in virtual classrooms with "facilitators" who can correct technical problems and monitor students. Known as e-learning labs, these virtual classrooms use computers to teach core subjects such as English and math. Each Web-based course consists of lessons with mostly text and some graphics. Instructors who can answer student questions are available via email or text message.

For some South Florida parents, however, there are no good answers about why their children were placed – sometimes without a choice – in virtual classrooms. "None of them want to be there," explains 15-year old Alix Braun about the other students in her Advanced Placement (AP) class. "This was not something they chose to do, and it's a really bad situation to be put in because it is not your choice."

In their defense, some school administrators explain that they're just obeying the law. Under Florida's Class Size Reduction Amendment of 2002, high school classrooms cannot have more than 25 students for core subjects. But that requirement applies to traditional classrooms – not virtual labs.

Are virtual classrooms the best way to educate the next generation of engineers? Or are e-learning labs just a way to avoid making hard choices about more costly, but ultimately more productive, educational investments?

BINGO!! Get used to it, folks. You're looking at the future of high school and university education. The way we do it now is more expensive than a graying America is willing to allow, especially if it has to be done with tax dollars. And middle class America is being completely priced out of university educations for their kids while they see their standard of living and disposable income shrink.

It will also drive a new mission for primary school teachers. Their job will be to shape, mold and prepare our children to teach themselves as well as instill in them the motivation to learn. Personal instruction will become an expensive commodity to be given only to the best of the best or the few families that can foot the bill.

The way this would work at the university level will be for those institutions to finally admit that they have been working a dual mission. It is not just actual education; but also the credentials that certify the career qualifications of the student. This distinction is critically important. That is because it forces an objective look at what resources go into each half of the mission. The inevitable result will be a realization of the astronomical costs that can be saved if students can be motivated to primarily self study and the work of professional educators to largely consist of curriculum building and student evaluation. Modern technology is rapidly enabling us to deliver instruction by easily mass reproduced interactive media methods. Miami Dade schools are truly touching the future with their program.

100 years ago International Correspondence Schools published and sold books through which a whole generation of early 20th century engineers and technicians (we didn't call them that at the time) learned their trades. Few could afford university educations. The only way was to grit your teeth and pound the books if you wanted to learn how to design and build the pieces of the American economic and technological power. And make a good living while doing it.

We're coming back to that in the 21st century. The real challenge to educators will motivating students and then figuring out how to accurately evaluate and certify them. Cost competition between educational institutions will drive that.

Now is the time to start.

GA! I have two sons in college studying math and computer science. They both started supplementing their studies using free course material posted by MIT, and at this point it's more like they are supplementing their on line studies by taking classes. My concern is that many students need mentors to steer them towards a solution from time to time. While banging your head against the wall for hours until you finally come up with a solution is an important part of the learning process, at some point all but the most gifted students will need some place to turn to for help.

johnfotl -- Have you sons check out Khan Academy as an alternate source for on line tutorials. Lots of good math and physics material there.

Hello Ed: I have a dynastar diesel engine, that I would to talk to you about. It is 32 in across. It is mostly complete and looks to be in runable condition. It has the bottom gear box and looks like nothing was ever hooked up to the output shaft.the engine was run before but not for very long. could you contact me at dan@bektel.com . thanks Dan

That's just semantics... someone needs a slap.
Sack the administrators, hire teachers.

Easier said than done here in the colonies, Del. We have administrators because the schools cannot be run locally. Why? It has to do with the "Equal Protection" clause in our Constitution. Solve the racial and ethnic discrimination problem, a very deeply rooted human trait, and you no longer need high level control of the institutions of learning.

The USA built a nation over a 170 year period by simply ignoring the discrimination issues with respect to education. Schools were a local issue and managed very effectively with very few administrators. Then the slowly grinding machinery of justice that builds a nation's true framework of law started dealing with discrimination. The net result was a centralizing of control over education with all the administrative control issues of any large organization. An organization's rules get polished with time and in the present day we have lots of new electronic command and control resources available to be tried out. This can result in a lot of leaning out of administrative overhead.

But, and these are some big "buts", the control costs will still be there as long as society fights the issue of racial and ethnic discrimination. If we choose to fight other forms of discrimination in the schools with a central government approach then we will make the problem worse. Possible types of discrimination run the gamut of human characteristics ranging from mental abilities to physical handicaps.

The other big "but" is public education "mission creep". The more things we ask public schools to do the greater the overhead costs will be. The dinosaur (that's as PC as I can be) in the room is the loss of parental support of the education process. Now the public school has to be the parent. But there is a gentle rain of other mini missions ranging across the spectrum of education from driver training to sex ed to school lunches to whatever the latest media fad of the week happens to be. (Let's make every child learn algebra even though 90% of them will never solve another algebra problem in their working lives.)

So it's going to be a long road to the goal of firing all the administrators.

About the 25 students per teacher thing. In the UK or USA what's a primary or HS teacher cost per year for salary, fringes, materials, admin and facilities overhead? US $150K? That's $6K per student across the board. Who's going to be willing and able to pay that for every student? We have 7 million student age people in CA. That's US $42 billion per year. The crush is being felt everywhere as everybody's disposable income shrinks (unless you're an investment banker). And the demographics of the advanced industrial nations in out world are showing an increase in the number of older people who have much less interest in supporting the education of other people's kids, especially the children of immigrant and racial minority populations (there's that discrimination demon again).

Maybe 20 or 25 students per teacher is needed in the lower primary grades. Electronic "props" are of very limited value there. But in high school? That's why I'm for automating it as soon as the student is able to take responsibility for his/her own education. That's why my pitch is to make a seemingly subtle change in the primary school mission from teaching the child the "basic" subjects to teaching the child how to learn both from inanimate sources and other people.
