Tuesday Tech Tip #8 - Screenshots

Last week I wrote a post about screencasts, great tools for sharing information through video. What if you just need a picture and not a full video? In that case screenshots are the solution. Screenshots are simply photographs of either a portion or all of your computer screen. Once snapped they can be easily shared via email, inserted in presentations, or posted on website. Depending on your computer platform or tool you have a few different ways to take a screenshot

Apple OSX
The ability to take a screenshot it built right into the Apple operating system. You have three choices for creating your image - snap an image of the entire screen, just one window, or a customized area.

• Entire Screen - Simply hold press Command+Shift+3 (all three buttons at the same time) and an image of your screen will be deposited on your desktop. If you have your speakers turned on you will even hear a camera-shutter sound.
• Just One Window - Press Command+Shift+4, move your mouse over the window you would like to capture, press the Spacebar, and click the mouse. On your desktop you will now have an image of that window. If your speakers are turned on you will hear the same camera shutter sound.
• Custom Section of the Screen - Press Command+Shift+4. Move your mouse to the upper left section you would like to capture, hold down the mouse, and drag to the lower right section would like to capture. When you let go of the mouse your screenshot will be deposited on the desktop.

For more detailed instructions check out this Apple Support webpage.

Windows 7

Devices running Windows 7 also have the ability to snap screenshots. This is done using the Print Screen button (PrtScn). Simply press PrtScn, launch Paint and paste the image into the program. Once pasted you can save the file and a picture to be used in another program. If you would like to only capture one program window click the window you would like to capture and press Alt+PrtScn and follow the same steps using Paint. More detailed directions can be found in this Windows tutorial.

Using Snagit for Chrome
If you're using a Chromebook OR you want the ability to easily annotate at screenshot of a website with text, arrows, or shapes then check out Snagit for Chrome. This free Chrome extension and app will allow you to quickly capture online resources, annotate key details, and share images via weblinks. The tool is free to download and will work with any NCS Google account. This video demonstrates how to install and use Snagit for Chrome.

Adding annotations in Snagit

iOS - iPad/iPod/iPhone
Last, but certainly not least is an iPad/iPhone. You can snap a screenshot by holding down the power and home button together for a brief moment. The screen will flash and an image will automatically be added to the Camera Roll. If you would like to annotate the photo from that point, check out Skitch for iPad/iPhone.

Screenshots are quick and easy ways to share information whether the content is a teaching tool or a student sharing their project. If you have any questions please let me know.

Teaching Through Screencasts

Screencasting.  It's a word many of us have heard, but most of us aren't completely sure what it means.  We just nod politely when techie people say it.

Screencasting is simply the process of creating a digital recording of something that is occurring on the computer screen and they often contain audio narrations.  As we weave increasing amounts of technology into all of the roles we play as classroom teachers, screencasts can quickly become handy tools.  In my own classroom I used screencasts to show parents how to log into our classroom blog and post comments and to remind students how to accomplish various tasks using Google Docs, Sliderocket, or Moodlerooms.  There are two reasons why I love screencasts:

• Just in Time Teaching - It's 3:30pm and you get an email from a student - "How do I embed my presentation on the class Google Site?  I can't remember."  You certainly could respond by typing out all of the steps and hope that the student doesn't miss one...OR...you could create a short video modeling it for them all over again.  Recognizing that if one student asked the question chances are a few others are confused as well, you could then send out the video to the entire class via email and even post it on your webpage.  
• Repetition without Repeating - One of the handy things about screencasts is that the videos can be watched over and over again.  Learners can review your instructions until they have mastered the concept and you only had to teach the lesson once!  When I taught technology elective screencasts honestly kept me sane.  During class I would model for the students how to use a particular application, but the night before I also created a few short screencasts of the key steps and posted them on my website.  When the students transitioned to independent practice they would use these videos if they had a question and I could move around the room assisting students with deeper concepts.

You're probably thinking, "these sound great, but I certainly don't have time to make them."  You do.  I promise.  It is easier than typing out the directions and can be done in three quick steps.  Here's a screencast showing you how.

• Record - On your Mac use QuickTime player to create your videos (Windows people - you have a couple of different options, so let's chat in person to see what will work best for you).
• Upload - Once the video is done look for Share and upload it to YouTube. 
• Post - While the video is uploading create your email or weblink where you plan on posting your video.  Once the uploading process is done just copy and paste the link to your video.  Hit send or save and resume your life.

Having created screencasts for the past few years I have three main points of advice for making your own.

• Keep it Short! - No one watches a video longer than 5 minutes.  Shoot for 1-5 minutes and if you find yourself running long consider chunking the video into two sections.
• Make it Interactive - If you need to go longer than 5 minutes and can't chunk the video then build in pause points where you encourage the viewer to stop the video and complete the steps you just mentioned. 
• Mistakes are Awesome! - Your video does not need to be perfect.  You are human and when you teach in real life chances are you make mistakes.  The same thing happens with video.  Simply correct yourself and move on.  It shows your human side and makes the video more interesting.  

If you have any questions about screencasting feel free to let me know.  We also have an expert in the math department who combines screencasting with a document camera.
