Heads Up! in PowerPoint for library class sessions

Since my John Jay colleague Kathleen Collins wrote about using active learning strategies in library “one-shot” sessions, I’ve been experimenting with games and hands-on activities to keep students engaged in the material. Typically, I cover library research basics in the sessions I teach: breaking a research question down into keywords (this is hard for freshmen!) and finding books/articles.

I frequently refer to “Don’t Do Their Work: Active Learning and Database Instruction,” a fantastic article in LOEX by Jennifer Sterling, which covers different active-learning activities she uses in her classroom. One in particular has been a breakout success for my own teaching.

Heads Up! is an iOS/Android app from Ellen DeGeneres (et al.) based on the old game Password, wherein the player who’s “it” must guess a word they can’t see based on hints from their teammates. It’s a great way to get students thinking about synonyms and related words for keywords, and it absolutely starts the class session off with a high energy level.

Because this is happening in the library classroom, I have adapted Heads Up! for a PowerPoint presentation. It’s a little hokey — it’s just a list of words that appear on-click next to a one-minute timer gif. Two volunteers from each side of the room stand in front of the projector screen so they can’t see the words, but their teammates can.

(This version includes different timer gifs on each page. I did this because sometimes Powerpoint glitches out when “restarting” the same gif on a different page.)

I ask for 2 volunteers from each side of the room. Both volunteers can guess when it’s their team’s turn (so that they don’t feel so alone at the front of the room, especially when they’re not doing well). Both teams get 2 rounds, meaning the game lasts around 4 minutes total (plus some banter in between). Usually, students get between 2 and 7 words. Note that these are general words, not library-y words. Something easy and low-barrier to engage students from the get-go. So far, my favorite moment has been for the keyword “Chiptole,” for which half the classroom devolved into students shouting “Bowl! Bowl! BOWL! BOWL!” at their flustered classmate. (“Cereal? Spoon? Plate? Salad?? Soup??”) Probably the most laughter that’s ever occurred on my watch.

I swear by this activity! Students absolutely get the connection between Heads Up! and the next part of my presentation, in which they pick keywords out of their actual research questions and find synonyms and related words, then trade worksheets with a classmate. (Warn them about trading ahead of time, if you’re going to ask them to do this.) This keyword-gathering activity, too, is inspired by that LOEX article.

Let me know if you use these or other active-learning approaches in your library classes. I’m always looking for fun ways to engage undergrads in the library curriculum.

Update (added August 12, 2016): I updated the slides. Also, there aren’t many 1-minute countdown gifs out there, so I made some in black and white, below. They’re set to run through the animation only once, so don’t worry if they’re all “00,” just download the gif.

See through the Internet: workshop handout

See through the internet handoutI designed a new 30-minute workshop for students this semester called “See through the internet: 8 questions & answers about how the internet really works.” I’ve given it a total of 1 time so far, to 2 people, today, but am scheduled for several more later in the semester. The subject matter is close to my heart, though, so I look for any opportunity to share this material. Perhaps you’ll find it useful, too. Here’s a draft summary of the workshop curriculum. Note that it is aimed as an intro for undergrad students.

8 questions & answers about how the internet really works

When is “the cloud” not a cloud?

All the time. What we think of as a wireless, wispy cloud is in fact made up of a vast network of wires, servers, hubs, and buildings. When you access your email or Dropbox or other cloud-based services, your computer is sending a request for files from another physical computer that lives somewhere else in the world.

How does a website get to your computer?

Pick a website and copy its URL. We’ll use nytimes.com here as an example.

On a Mac: Open Terminal (search for the program) and type traceroute nytimes.com

On a PC: Open Command Prompt (Start menu » All programs » Accessories) and type tracert nytimes.com

Browser option: Go to tools.pingdom.com/ping and choose traceroute (it’ll be testing from Pingdom’s computers, though, not yours). Type in the URL and submit.

Traceroute will show you all the routers (internet connector points) your computer must contact to request to access a webpage. It’s tracing a map across the city, or even the country, or even the world as your request travels from router to router to find the server (special computer) that hosts the website (stores the website’s files). Think of it like a highway that connects many cities: if you’re driving from San Diego to Seattle, the highway doesn’t go straight there — it also runs through other big cities like L.A. and San Francisco, because traffic is more efficient that way.

Each router or server will display an IP address, the numerical address that only that machine is assigned. So “nytimes.com” is actually just a human-readable version of the real web address for the New York Times, which is, a computer that is probably downtown. In between your computer and nytimes.com, there are many other IP addresses. Using some internet sleuthing skills, you can find out where these IP addresses are located geographically and/or who owns them.

When to use this: Use traceroute when you want to visualize how far away a website is, or when you want to diagnose whether a website is not loading because of a problem with your network, the website itself, or somewhere in between.
