Computers in Elementary School

Should elementary kids learn computers? Some say that computers cannot help and might even be distracting, at best. Others say that in this age of computers we need to start our kids off early.

Its fine for elementary kids to learn how to use a computer for something other than games, but its far-fetched to suggest that it will help them use computers later. Using the typical tools -- word-processors & spreadsheets -- takes very little training.

On the other hand, I'm not a complete Luddite about this either. I think that some well-constructed teaching programs can be useful. They are particularly useful in drill. There are many things that a child learns by mental drill -- repetition.

Here's one example from the life of my 6 year old. He's learning certain "math facts". Having past the stage of being able to add number by counting, he is now being taught to memorize some. Presented with any pair of single digit numbers, he should be able to recall their sum, difference and product, without having to mentally add, subtract or multiply them.

He was stuck on the memorizing the products. His "7 times tables" were hard, and so were 8 and 12. Every day, I would quiz him on two or three pairs. In a spare moment, I might ask: "So, what is 7 times 8". After about a week, I found that he was able to remember more. So, I wrote a small software program to:
  • display a "problem", like " 7 x 8 = ??";
  • accept an answer; and,
  • say if it was right or wrong.


It also displayed a score at the top of the screen, "You got 5 right out of 6". I randomized the selection of numbers that would be presented. I also made it log each question and whether it was answered right -- that way I could review it and see if he was having trouble with certain specific pairs (why is "7 times 8" so hard?).

It worked! He has been able to drill at odd moments, and without my being there to help him. The drill has improved his retention of the "Math facts". He even finds the process mildly interesting.

So, yes, a computer can be a useful tool, if applied to the right type of educational problem. Not the computer as something to learn, but the computer as a tool to help teach something else.

    I like to drop little bombs after reading blogs and blog comments. Good bombs, but they can be very explosive.

    Here's yours...

    Sometimes all it takes to start a person thinking about life, how they live it and how they would like to see it turn out, is a question.

    Granted, it has to be the right question.

    And it isn't asked very often.

    I'll bet you have never asked another human being the following question...

    ...and this particular one might even change your life, that's what I'm hoping anyway.

    Ready.

    What is your ultimate goal in life?

    Do you know? Have you written it down. Do you have a plan? How are you going to reach it? Just get lucky perhaps?

    I don't think so.

    No matter what it is, if you haven't written it down, visited it often, know what it is you really want and have a real plan to get it - it will probably never happen!

    Just thinking about it, hoping for it and wishing it would happen won't work. You know that.

    However, there is a way, and as an educated individual, you already know what it is, but you've probably been like most of us, you are too lazy to do anything about it.

    You know I'm right.

    However, if you're willing to make the effort and learn how to set goals and follow up on goals you can make a HUGE difference in the outcome of your life.

    I hope I made you think, and more importantly, take action.

    Get a ton of FREE goal setting information at goal setting techniques and have a Happy New Year!

  • Hi softwareNerd. I was looking for some info on spy software and came across your site. Although Computers in Elementary School was not what I was after exactly, it certainly got my interest. I see now that I found your page when I was looking for spy software related information. Even though it was not a perfect match I'm glad I stopped by. Good post - have a good day.
