Earlier this year I got a free advanced copy of Decisive from Chip and Dan Heath before it was released to the public. I got it because of a tripwire. I’ll explain.
So, here’s how it happened. I signed up for the Heath brothers’ online newsletter so that I could download a PDF that summarizes their book Made to Stick. A few months later, they emailed to give me access to a chapter from their forthcoming book. Towards the end of that chapter, hidden somewhere in the middle of a page, they cached something like this in a parenthesis: “(If you email us some feedback about this chapter, we would love to send you an advanced copy of our new book Decisive.)” That hidden sentence was the tripwire. They could have put this at the beginning of the chapter, or in their email, but they wanted feedback from people who they knew really read most or all of the chapter, not just those moochers who wanted a free book that they might not even read.
In that book, Decisive, they explain how the band Van Halen required a bowl of M&M’s backstage as a tripwire for their shows. You can read the entire story by downloading the first chapter from their site: http://heathbrothers.com/books/
So, I thought I’d try this out with my online students. I had created a 10 minute screencast to coach my students on a particular phase of an assignment. It was critical that their teams watch all of it (it was a collaborative project). I knew that if they didn’t watch the entire thing, then I might have a bunch of confused learners, poor quality submissions, and a lot more work on my hands. So, I set a tripwire.
I told the students that somewhere in their screencast, they would find an unusual phrase. They needed to take the phrase and type it into the header of their next assignment. Without the phrase, their maximum grade would be an 85%.
Here are a few benefits I noticed from using a tripwire in online assignments:
1) It saved me time and put the responsibility back on the learners. Usually, I’d be tempted to create a quiz or to have my student fill out something that said, “I’ve watched the whole thing…” Why should the instructor be doing more work in order to get students to meet basic expectations? This put the ball back in their court.
2) It created mystery. They were listening for the phrase and more attentive as a team to the screencast. Of course, I didn’t try hard to hide the phrase; in fact, I pointed it out, but they still had no idea at what minute and second it was going to pop up.
3) It was fun. I made the phrase silly. They all involved some small animal, a geographic location, and some kind of martial arts noun. For example. Galilean Ninja Weasel.
Try it out. How could you give teeth to an assignment like watching online lectures or completing reading or a screencast by using a tripwire?
