WolframAlpha Facebook Report

This is a delightful exercise that everyone seems to love. WolframAlpha will provide you with an extremely detailed analysis of your own Facebook data including visualizations, world clouds, graphs, and more.       Here’s how: Go to WolframAlpha.com. Type “Facebook Report” and execute the search. Allow WolframAlpha to have access to your Facebook account by clicking on “Analyze my Facebook Data” and following the directions. Wait while the data is analyzed. Note: Sometimes the report seems to stall after 100% of the data is analyzed. If this happens, simply repeat steps 1-3. The second time, the report seems...

Navigating WolframAlpha Pro Features

Last week I had to do a workshop about WolframAlpha, and I noticed that there are three different feature sets: not logged in, logged in, logged in to Pro. I needed to know which login settings provided which features (especially for giving workshops and working with students), so I decided to be thorough about it.  You can download the PDF of this document, Guide to Wolfram Alpha Features, as well. Hope this makes the decision-making a little easier for you!   Possibly Related Posts: Elaborations for Creative Thinking in STEM Learning Math is Not a Spectator Sport Recorded Webinar:...

Wolfram Alpha Discovery

Okay, technically it was a workshop at ICTCM, but with 30 math faculty in one room, all armed with computers, I couldn’t help but make it a discovery and brainstorming session too.  I’m a firm believer in harnessing the power of a room of people instead of talking to them (provided that we have some technology to facilitate that). This post is Part I … the discovery portion of the workshop. One of the things that made this workshop a bit out-of-the-ordinary for math workshops was that I set up a “backchannel” for participants to use to share their thoughts, discoveries, and ideas.   To do this, I used a Chatzy Virtual Room – anyone can “join the room” as long as they know the URL – just state your name, and you’re in the chat room.  This made the discovery process collaborative, as well as fast and furious as everyone in the room got a chance to contribute to the conversation in real time. The first question I was asked (which I am asked in almost every workshop I do), is how on earth I was magnifying just a small portion of the screen (like where the input box was).  I use a free tool called the Virtual Magnifier. The group “play” with Wolfram Alpha lasted for about an hour, during which we (they, mostly) discovered quite a few...

Wolfram Alpha for Inquiry Based Learning in Calculus

Now that all my Calculus II students know about Wolfram Alpha (I showed them), I have to make sure that the assignments I ask them to turn in can’t just be “walphaed” with no thought.  In Calc II, our topics list includes a lot of “techniques-oriented” topics (integration by partial fractions, integration by parts, etc.) and because of the need to keep this course transferable to 4-year schools, I can’t really get around this.  So now I’m in the position of having to reconcile the use of technology that easily evaluates the integrals with making sure that students actually understand the techniques of integration.  There are two ways I’m tackling this: 1. CCC (Concept Compare Contrast) Problems: I’m writing problems that focus on understanding the mathematical process and the compare/contrast nature of math problems.  While Wolfram Alpha can evaluate the integrals for them, the questions I’ve asked require (I hope) a deeper level of understanding about what happens when the techniques are used.  Here’s an example from my recent problem set: There are two pairs of problems below that are exactly the same. You won’t see why until you do the integration, showing all the steps. Find the pairs and then explain how the matched integrals are fundamentally the same. 2. Inquiry Based Learning: One appropriate use for any CAS (computer algebra system) is to use it as a...
