Individualized instruction

Seems like I say this a lot, but it is true that as homeschoolers we can do all the things that professional educators know are best practices. A few months ago, I mentioned the science teacher who likes to take his kids out into the woods to experience nature for 20 minutes! As homeschoolers, we can do that for hours -- and we can do it every day if we want. One of the other big strengths of homeschooling is that we are able to provide individualized instruction for our children. This is something that the pros know they need to do, and they are continually trying to figure out how to deliver individual instruction to 20 or 30 kids in a classroom.

Jim Bower, a neurobiologist at the University of Texas and the CEO of the virtual world Whyville, recently explained at an educator's conference:

We tend to learn best through hands-on experiences, he explained--by trying things ourselves and taking ownership of our own learning, rather than passively receiving information from another source. But until the internet came along, we haven't had a scalable way to deliver this kind of experience to every student.

Before the internet, Bower said, the two most important developments from an educational perspective were the invention of the printing press and the creation of a university system. But both of these developments were "push" operations, he said--meaning they pushed information out to students, rather than letting students experience learning for themselves.


I agree with Bower, but after spending time teaching in three different public high schools over the past few months, I can tell you that most schools are not even close to giving kids the kind of education that is necessary and possible in the World Wide Web. Almost zero students have heard of a blog, Twitter, Squidoo, or any other Web 2.0 tools and programs. This semester I surveyed my high school seniors and learned that most of them spend very little time online, and almost 100% of that time is spent on either Facebook or MySpace.

Most schools have a single computer lab, but little time is spent in there. This is where homeschooling parents can easily give their children a better education than the public schools can. If you're reading this blog, you are already more Internet literate than a lot of public school teachers. So, don't be shy about searching the net and looking for learning opportunities for your children, and let your children look for information on subjects that interest them. If you're new to this blog, read some of the older posts about how blogging can improve kids' writing or how you can learn critical thinking skills through the Internet.

As I said, I totally agree with Bower's ideas that the Internet can be used to deliver individualized content to students, but it will not happen if kids are getting half an hour per week on a computer. Sadly, most districts don't have enough money to allow students more time online. And Bower even admits in the article, "'We haven't figured out how to leverage Web 2.0 yet' in schools." Well, while the school districts are still trying to figure that out, homeschooling parents can continue delivering the best possible education to their children.

Thinking vs. testing

Like most people, I love it when I find kindred spirits -- you know, those people with whom you agree. Finding this article came at a good time for me. I am down about some of my college students, so it's especially nice to find a person -- a Harvard person, no less -- who voiced many of my opinions about what schools need to be teaching and doing.

In Seven skills students desperately need, author Meris Stansbury talks about a keynote address delivered by Harvard's Tony Wagner in which he says that while schools may be successfully teaching to the test, kids are leaving schools without the survival skills that they need for the real world. Bravo! My sentiments, exactly! Wagner relates how he has visited schools where students just wait for the teacher or a star student to give them the answers -- even if a Bunsen burner is smoking!

In my student evaluations, it is not uncommon for someone to write something along these lines ... "When we ask you a question, you should just answer it. Don't ask us a question." And a few weeks ago, when I passed out an exam to my students, I told them not to get caught up in whether to say yes, no, or maybe in response to an essay question, because I would be grading them on the "why" behind the yes, no, or maybe. Several students groaned in agony. Ever since I started teaching college more than two years ago, I have noticed that students do not like to think. "Just tell us the answer!" is written all over their faces. I am constantly telling them that to succeed in college and in life, they have to think! They can't just memorize all the right answers, because usually there is not a single right answer.

One of the reasons that schools fail is because they are trying to get students to memorize a bunch of stuff that they will forget as soon as they take the test. The emphasis is on "knowing" the right answer, rather than critically thinking to figure out what one answer might be. Whether I am at home or in a classroom, I rarely give a straightforward answer to a child's or student's query, because no one should look at me as the expert on everything. Students should realize that they can figure out the answer on their own. One of the my favorite things as an unschooling mom was to hear my young children talk about how they taught themselves to do something.

When people ask me if I think that the state should have oversite of homeschooled students, I quickly respond no. Why? Because no doubt that would include testing, and then homeschooling parents would start making the same mistake that public school teachers are forced to make -- teaching to the test. Educators know that teaching to the test ultimately fails students, because it doesn't teach them to think. But it is legislators, not educators, who make the laws. They want quantitative proof that students know something. And I suppose they get proof that students know something -- but standardized tests do not prove that students can think.

The real thing

My college students are in the midst of a critical thinking exercise. They are supposed to visit three Web sites and decide whether or not they are credible.
Being the eternal optimist, in every class and in every semester, I eagerly await their posts on the discussion board online. And every year I am frustrated and disappointed. I've been sitting at my computer this morning, reading their responses and thinking about how I'm going to respond. And in so many cases, I find myself saying, "You're not in high school anymore." For so many of them, the goal is not learning -- the goal is a grade. Some have a goal of A, and some have a goal of C or even D. In this critical thinking exercise, most of them are just throwing an answer against the Cyberwall to see what sticks.

I've told them that obviously, we know men can't get pregnant, but I want them to look at the site like an alien. If you don't know men can't get pregnant, how would you determine that this site is a fake? I do this because when they choose a speech topic, they will be entering a foreign world where they don't know what is or is not possible. There will be thousands of sources out there from which to choose. Some will be good; some will be biased; some will be wrong. They need to have critical thinking skills to determine whether a site is credible or not. Every semester I have students lose points on their speeches because they use sites that are not credible. So many of them scoff at my warning and saying, "Well, it's just common sense." Here are a couple of the responses:

I just can't bring myself to believe this. Although it does have newspaper articles and other credible sources, I just can't believe it.

The site is not credible because the live vital signs only show results and no proof that a man is actually hooked up to the machines.
Students #1 is a perfect example of someone who will probably use sources that are not credible. She's in a hurry and didn't take the time to actually click on those links to see if they really do lead to the "credible" sources that she trusts.

Student #2 is thinking skeptically, not critically. How could any website prove what he is suggesting? If it were following a woman's pregnancy, how could they prove that it's real?

This is actually an easy site to debunk. If you click on any of the links, you see that they do not go to stories about the pregnant man; the links just go to the home page of those sites. Also, there is no physical address or phone number for the medical center. You can't even figure out what state it's in. If students only took the time to google "pregnant man" or "Dwayne Medical Center," they'd find other sites that say it is not credible. But most students don't think about double-checking their sources.

The DHMO site is a perfect example of how someone can make something look really bad. Everything on that site is absolutely true. But it is a perfect example of bias. So many students think that biased = wrong. Although DHMO does all of those horrible things, it is also absolutely essential for life. As they say in advertising, the truth is irrelevant -- what's imortant is what people believe! Don't be too quick to say that no one would really make something good sound so bad. The government has done exactly that with raw milk. While raw milk has many health benefits, the government has banned it or severely restricted it in many states because big business has convinced them it is just as dangerous as DHMO. By the way, DHMO is water, and as a result of this site, some people have tried to have it banned -- until they learned that it is water.

The skunk site is credible, and a few students pointed out some good things about it, so today I'll be ending that discussion, and I'll add another one: The Lovenstein Institute. That website was created as a result of a hoax email sent out in 2001 saying that Bush had the lowest IQ of any president ever to be elected, according to the Lovenstein Institute. Today, they throw all sorts of interesting stuff up there and mix it with legitimate news, which makes it a little harder to decipher. Since no one has offered any good answers to the DHMO or male pregnancy discussions, I'll leave those up and ask students to continue responding.

This is what I'll be telling my students ... This is the real world. If you're a doctor, you have to diagnose your patients' illness or condition. If you're a lawyer, you have to figure out the best strategy for defending your client. If you're a physical therapist, you have to figure out the best treatment for your patient. If you're a teacher, you have to figure out what works and what doesn't work with your students. If you're an advertising executive, you have to figure out what will sell your products. You can't just throw something out there and wait for someone else to give you the "right" answer. In real life, no one knows the right answer most of the time. You have to use your education and training and critical thinking skills to figure out the best answer. If you choose the wrong answer, your patient might die, your client might go to jail, your students might not learn, your company might go bankrupt. That's the real world. You don't get grades in the real world. You have to think and make decisions, and if you're wrong, the consequences can be much worse than an F.
