Is dependence on technology the real threat?

I came across this Seymour Papert quote over the weekend, the best part of which is below. In context, Papert is speaking about effecting real change in the content of school mathematics, and he focuses particularly on the teaching of fractions:

One theory [among educators about why we should teach fractions in school] was that manipulating fractions was actually closer to what people needed back before there were calculators. So a lot of school math was useful once upon a time, but we now have calculators and so we don’t need it. But people say that surely we don’t want to be dependent on the calculator. To which I say, Look at this thing, these eyeglasses, that make a dramatic difference to my life and the life of everybody who reads or looks at any tiny detail. Once upon a time we would have been crippled, severely handicapped. Now we’ve got these and we don’t need to go …

Will the Fire burn its way into higher ed?


In case you didn’t hear, Amazon has announced a major upgrade to the entire line of Kindle devices, including a new 7″ tablet device called the Kindle Fire. The Fire won’t be released until November 15, but already the phrase “iPad killer” is being used to describe it. Wired Campus blogger Jeff Young put up a brief post yesterday with a roundup of quick takes on the Fire’s potential in higher education. One of those thoughts was mine. I’ve had some time to look around at what we know about the Fire at this point. I have to say I am still skeptical about the Fire in higher education.

It seems like the Fire is a very well-made device. I’m not so interested in getting one for myself — I’ve got a current-generation Kindle and an iPhone 4, and am very happy with both …

Helping the community with educational technology

Many people associated with educational technology are driven by a passion for helping students learn using technology in a classroom setting. But I wonder if many ed tech people — either researchers or rank-and-file teachers who teach with technology — ever consider a slightly different role, voiced here by Seymour Papert:

Many education reforms failed because parents did not understand or could not accept what their children were doing. Remember the New Math? This time there will be many who have not had the personal experience necessary to appreciate fully the multiple ways in which digital media can augment intellectual productivity. The people who do can make a major contribution to the success of the new initiative by helping others in their communities understand the potential. And being…

How I make screencasts: The whiteboard screencast

In this post, the fifth in a series of posts on how I make screencasts, I’m going to focus on what I call the “whiteboard” screencast. This is a screencast where I am demoing some sort of concept or calculation by writing things down, rather than clicking through a Keynote presentation or typing something on the screen. It’s intended to mimic the live presentation of content on a whiteboard, hence my name for it.

Of course the most well-known examples of “whiteboard” screencasts are the videos at Khan Academy. In the unlikely event you haven’t seen a Khan Academy video before, here’s one:

I do whiteboard screencasts fairly often. I use them sometimes for presenting hand calculations for students to watch and work through before class, and sometimes (probably more frequently) I use them to create additional examples for things I’ve covered in class. This is a really powerful use…

How I make screencasts: Lecture capture, part 2

Now that school’s out, I’m going to pick up where I left off (two months ago!) in my series on how I make screencasts. So far I’ve made three posts in this series. In the first post we talked about what a screencast is, exactly, and why anybody would want to make one. In the second post, we saw how the elements of careful planning make screencasting a successful experience. And in the most recent post, we took a look at using Keynote (or PowerPoint) to create a lecture-capture screencast.

Before I talk about the other kinds of screencasts I make, I’m going to take this post to describe how I use my go-to tool for screencasting: Camtasia for Mac, specifically how I use it to make lecture capture videos when I’m not using Keynote. (Full disclosure: I was on the beta-testing team for Camtasia for Mac and got a free license for the software for my efforts. But I can definitely say that I’d …

Three things I wish Google Documents would let me do

Let me preface this article by saying that I really like Google Documents. It’s a fantastic set of tools that extends basic office functionality to the web in really compelling ways. I’ve been incorporating Google Docs pretty centrally in my courses for the last few years — for example, I no longer hand out paper syllabi on the first day of classes but instead write the syllabi on GDocs and distribute the links; and I’ve given final exams on Google Docs with links to data that are housed in Google Spreadsheets. I love being able to create a document on the web and just leave it there for students (or whoever) to come see, collaborate, and comment — without having to keep track of paper and with virtually zero chance of losing my data. (If Google crashes, we have much bigger problems than the loss of a set of quiz data.)

But like anything, Google Documents isn’t perfect — and in…

Technology making a distinction but not a difference?

This article is the second one that I’ve done for Education Debate at Online Schools. It first appeared there on Tuesday this week, and now that it’s fermented a little I’m crossposting it here.

The University of South Florida‘s mathematics department has begun a pilot project to redesign its lower-level mathematics courses, like College Algebra, around a large-scale infusion of technology. This “new way of teaching college math” (to use the article’s language) involves clickers, lecture capture, software-based practice tools, and online homework systems. It’s an ambitious attempt to “teach [students] how to teach themselves”, in the words of professor and project participant Fran Hopf.

It’s a pilot project, so it remains to be seen if this approach makes a difference in improving the pass rates for students in lower-level math courses like College Algebra, which have been at around 60…

Technology FAIL day

This morning as I was driving in to work, I got to thinking: Could I teach my courses without all the technology I use? As in, just me, my students, and a chalk/whiteboard with chalk/markers? As I pulled in to the college, I thought: Sure I could. It just wouldn’t be as good or fun without the tech.

Little did I know, today would be centered around living that theory out:

  • I planned a Keynote presentation with clicker questions to teach the section on antiderivatives in Calculus. As soon as I tried to get the clickers going, I realized the little USB receiver wasn’t working. Turns out, updating Mac OS X to v10.6.5 breaks the software that runs the receiver. Clicker questions for this morning: Out the window. Hopefully I’ll find a useable laptop for tomorrow, when I’m using even more clicker questions.
  • Also in calculus, the laptop inexplicably went into presenter mode when I tried to…

Get your widget on

Wolfram, Inc. has just rolled out its newest creation: Wolfram|Alpha Widgets. These are small “apps” that execute a single W|A query using user input, without actually loading the W|A website. In just the last few days since W|A widgets have been around, hundreds of them have been made, from widgets that find anagrams to widgets that calculate comparative economic data between two states to widgets that take derivatives. Each widget also comes with the option to customize, share among social media applications (21 different services are represented), or embedded in popular blogging and wiki services such as WordPress and Mediawiki. (Sadly, there’s no WordPress.com embedding yet.) Take a look through the gallery at what’s been done.

What’s really exciting here is that you don’t need any programming knowledge to create a widget. You start with a basic W|A query, then highlight the…
