Apple Tip: Slider Cell

Apple Tip: Slider Cell

As part of the State of Maine’s 1-to-1 laptop initiative (MLTI), the Project Office has enlisted a team of integrators to provide training and tips to teachers and students across the state to help them be more efficient users of their Apple laptops. Called MLTI Minute, these training podcasts cover topics across different applications, utilities, and web tools.

In a recent episode, MLTI Minute highlighted an interesting tool when working with a data table found within the application Numbers. Called Slider Cells, this tool essentially allows you to take a plain old data table and turn it into an interactive tool. In the podcast, they use the example of a data table made to calculate the interest payment on a principal loan. The podcast shows you how to activate the slider cell tool and configure it based on the type of data you are working with.

Curiosity got the better of me at this point, and I wanted to see if this new interactive tool would allow me to manipulate a chart/graph based on the data in the table. I created two charts to represent the changes made to the rate and the resulting interest amount. When I used the cell slider to manipulate the rate, both charts adjusted to reflect the changing data. I now had a truly interactive tool that I could control and change with the click of my mouse.

How-To Tech Tip: The Pleasantville Effect

This screencast will show you how to create a “Pleasantville Effect” (a.k.a. sin city effect) on an image. We will use the application Acorn that comes pre-installed as part of the MLTI image, although you can achieve the same effect using similar photo-editing software such as Adobe Photoshop.

Google Apps Tip – Historical Imagery

Historical Imagery – Using Google Earth to see change over time

Historical Imagery is a fantastic, yet often overlooked tool found in the free application Google Earth. This tool allows the user to view a location on the planet at different points in time thanks to Google periodically updating its maps with newer satellite images.

To use, find and turn on the Historical Imagery button in the menu bar. This will display a timeline bar with several white marks spaced along it. Each mark represents a different satellite image taken at certain times. To see this tool in action, check out the MLTI Minute video podcast, episode #187: “Using Historical Imagery.”


  • This could be a great tool to use with students to show the impact and change of the landscape over time as a result of human construction projects within the last 20 years or so.
  • I’ve included two screenshots below of our middle school to show how the landscape has changed since its construction.

Digital Storytelling @ACTEM

As soon as people developed a mode of communication, they also started to tell stories. Now in the 21st century, storytelling has entered the digital age and the opportunities to express one’s tales of mystery, adventure and understanding are almost endless. As educators, we have a duty to listen for the stories that students have created and expose them to the variety of mediums they can use to tell them.

This year at the annual ACTEM conference, I had the privilege of co-presenting a session with Eric Lawson on Digital Storytelling. Our presentation aims to open people’s minds to just some of those opportunities by way of showcasing examples of digital storytelling that are taking place in our schools. It is our hope that our stories will spark interest in our fellow educators and encourage them to create their own plan to bring digital storytelling to their students.

Website of the Week: Viddler – A friendly video platform is an online video hosting site where you can control who can watch your videos and leave comments and tags in response. Videos can be either uploaded from your local computer or, if your computer is equipped with a webcam, recorded directly to their website. While the initial service is free with a sign-up, the site may include ads around your video; ad-free video hosting is a paid service.

Free Technology for Teachers author Richard Byrne recommends using the site to record video sub plans. This way the sub can play your video for the class and eliminates the he said/she said confusion that sometimes arises.
