Over the break, I had the opportunity to experiment with an iPad 2 that my department has purchased. The department is loaning the iPad out to faculty for two weeks at a time to see if there is a compelling educational use for the device with our students — in which case, I’m assuming we will try to buy more. As tech-obsessed as I am, this is the first time I’ve had to spend time with an iPad, and here are my impressions.

As a piece of high technology, the iPad is pretty marvelous. I’ve been an iPhone 4 user for some time now, so the beauty of the iOS user interface ought to be commonplace for me, but it isn’t. I can see why Apple marketed it as a “magical” device when it first came out. It certainly has the look and feel of magic. I enjoyed using it (and so did my kids, even though they were not technically supposed to be handling it).

I have been using clickers in my classes for three years now, and for me, there’s no going back. The “agile teaching” model that clickers enable suits my teaching style very well and helps my students learn. But I have to say that until reading this Educause article on the flight out to Boston on Sunday, I hadn’t given much thought to how the clicker implementation model chosen by the institution might affect how my students learn.

Different institutions implement clickers differently, of course. The article studies three different implementation models: the students-pay-without-incentive (SPWOI) approach, where students buy the clickers for class but the class has no graded component for clicker use; the the students-pay-with-incentive (SPWI) approach, where students purchase clickers and there’s some grade incentive in class for using them (usually participation credit, but this can…

Blogging’s been light this week due to a stupid instructional decision to give exams in all three classes on the same day a couple weeks ago and then dealing with the grading fallout, plus having to get an actual print article finished by deadline. Let me ease back into it by sharing this quote by Seymour Papert that I just found, which really sums up my thoughts about teaching and technology:

The best teacher is someone who brings personal knowledge, warmth and empathy to a relationship with a learner. The effect of the new technologies is to provide better conditions for such teachers to work directly with their students. Of course tele-teaching has a role, but I hope it will never be the primary form.

That was from 1997, but it rings true today as well. It’s easy to forget these days that education is a fundamentally human thing, and at bottom it’s about relationships (and trust). …

I’ve been taking a blogging break this week to get caught up at work, but I wanted to say a few words on the passing of Apple CEO Steve Jobs. Those of us who are lifeless Apple fanboys follow Apple news know that Steve had been very sick for some time now. His passing is not unexpected, but it is still a shock now that it’s happened, and it’s a sad day.

My first experience with an Apple product was using an Apple IIe while I was an undergraduate psychology major. The psych department had a small computer lab with some Apples in it, and I used one to run statistical analyses of an experiment I was doing. I hated the Apple IIe. To me, it was a computer for English and art majors, or perhaps for elementary school children. All those cutesy graphics! And music! Hard-working and self-respecting science nerds such as myself shouldn’t stoop to such devices. But, it was the only machine in…

To all the new readers: Ready for some math? We love math here at Casting Out Nines, and I’ll be taking at least one day a week to talk about a math topic specifically. If you have a math post you’d like to see, email me (robert [dot] talbert [at] gmail [dot] com) or leave a comment.

The Fundamental Theorem of Calculus is central to an understanding of how differential and integral calculus connect. It says that if f is a continuous function on a closed interval [a,b] and x is in the interval, then the function

is an antiderivative for f. That is, F’(x) = f(x). The FTC (technically, this is just one part of that theorem) shows you how to construct antiderivatives for any continuous function. Possibly more importantly, it connects two concepts about change — the rate of change and the amount of accumulated change in a function. It’s a big deal.

Last week, I had the chance to attend ScreencastCamp, a weekend event put on by Techsmith, Inc. just down M-6 in Okemos, Michigan. What a great experience! Techsmith develops Camtasia, my go-to software for all screencasting needs, as well as several other great products like Jing and SnagIt. I’ve been a fan of their products for a long time, and it was great to spend time getting to know the people behind them.

ScreencastCamp was an unconference, where there is no set agenda beforehand. Participants just come with an idea of what they want to learn, and then either put on a session or request one. There were about 40 of us participating, mostly from education but with a healthy contingent from the corporate (training) world as well. Amazingly, although this is a relatively small number of participants, all the session slots for Saturday and Sunday filled up almost immediately as people…

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…

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 …

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…

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…
