Want more feedback from students? Scan away!


Plickers are awesome.  Just ask Amanda McKay.

It's the end of 4th hour and Amanda's physics students have been hard at work learning how to calculate net force.  A poll question appears on the board.  Her students reach under their desks and reveal personalized QR codes.  As they hold up their codes, Amanda scans the room.  In a flash, Amanda knows every student's response to the question.

I asked Amanda three questions about plickers.  Here is what she had to say:

What are "plickers"?

"They are what I call Paper cLICKERS.  The mini QR codes that are printed on them can be oriented in four ways to show four different choices for a multiple choice question and are aimed at an Android or Apple device that interprets the choices.  A live bar graph is shown on the device as responses are read.  A correct answer can be chosen and would then be shown as a green bar on the graph."

How do you use plickers?

"I use them to collect quick bits of formative information to assess what students know or how comfortable they feel about a topic that we've covered.  They are secured to the underside of my desk tops with velcro and students can quickly take them out and show me their answers."

What do you like most about them?

"It quickly gives me important information regarding whether students are ready to move on or need to spend more time on a topic, and, as long as my phone is charged, I can run the app (even in airplane mode with no connection)."

Your shoeboxes are full...break is a perfect time for this app.

1994 - Somalia just south of Mogadishu. 
We all have tons of actual physical pictures and would love to digitize them. Have you ever taken a picture of a picture? It usually looks awful, too dark or full of glare.

This break why not download the PhotoScan app from Google and start sharing those old pictures! This is a free app that works on both Android and iOS.


Download and install the PhotoScan app.
Follow on screen prompts.
Follow the arrows. You will move the open circle to the closed white circle. The while circle will turn blue, then follow the arrows to the next circle.
Bam! You now have an image that is digitized and ready to share! 
My next steps will be to open this in the Google Photos app and start to adjust the color a little.

Well that didn't go as expected...

I had this idea that I thought would be epic. The point was to help teachers see the power video can have over people. I started by showing a tiny clip of the Slap Chop. This was a product from a few years back. The infomercial played on cable and in the wee hours of the morning but the thing sold making someone millions.

The original video moved people to remix it.  That sold many more Slap Chops. Just google Slap Chop Remix, it is hilarious!

The final outside of education idea was the My Pillow.  You might have seen this on the news lately for deceptive advertising practices. Even after the news and government told people not to buy it, they still bought pillows. So many the company is manufacturing 25,000 pillows every single day. That is not a small number of pillows.

These three examples were meant to show the power of a convincing video. These videos moved people to do something they might not otherwise do on their own.

The final was to show how a student uses video to convince…

Shortcuts - we all love them.

Here are a few keyboard shortcuts for Windows 10 that we find useful. Somewhere I read that using the keyboard is actually more efficient than the mouse, try it and see what you think.


All of these shortcuts will require you to use the Windows key on the keyboard. Where is the Windows key? Look on the lower left side of your keyboard. The key has four white squares on it, it kinda looks like a window with four panes.

Hitting the Windows key alone will open the Start menu in the lower left side of your laptop screen. Hitting that key in combination with others allows you to do some amazing things saving tons of time.

Windows Key + D = Display and hide the desktop. When I am using Chrome and I need to quickly get back to the desktop, no more hitting the little minus sign in the upper corner of the browser window.

Windows Key + E = Opens the File Explorer, similar to My Computer from back in the day. I use this when I have to pull a file from a flashdrive or SD card.

Windows Key + Right/Le…
