[Update: Videos about images on the handheld and what can be done with the TI-Nspire Navigator are now available on youtube. To transfer a file that you inserted an image on from the computer to your handheld, try this video tutorial. The basic insert image tutorial is here.]
Diagrams and pictures can help student engagement and exploration. The TI-Nspire Navigator 3.0 makes it easy to evaluate students in engaging ways. It encourages a new means for students to communicate their explanation of the relationship between their mathematical model and an image. This extends their learning beyond the normal rote problem set into an interactive investigation. Today in class I used the last image in this blog entry, the NASA Space Shuttle launch, to see how well students could write an equation of a line. They said they wish their previous math teacher could have used this. It would have helped them learn and understand slope and y-intercept so much better.

So how do you insert a picture or image into a TI-Nspire document? It is essentially and easy and clicking 'Insert.'
From the software, images can be put into Questions, Notes, Graphs, Geometry, and Data & Statistics applications by clicking the 'Insert' button and choose 'Image...'.
Images convert from color into grayscale well on the Touchpad or Clickpad handheld devices.
The screen shots you see can be found in the 3.0 OS TI-Nspire document here.
All text and lines are mapped to black.
Here is an example from Data & Statistics page. Images can be modified by moving them, change the size but keeping the aspect ratio, squish or stretch vertically or horizontally. Again, on a D&S page select the image by pressing menu, Action, Select Image.
Gray is the default color for students and green is the correct answer. Under the Review Toolbox is a wrench and hammer. By clicking this Tool and choosing Graph Tools, Individualize Student Responses can be activated.
I know the summer workshops will give more hands on experience with images and tips for the use of color. The Connecting Math & Science workshop in Indianapolis (among other places) will also share some updated colorful files to help encourage students toward STEM careers. They will also have colorful 3.0 Nspire files for some NASA activities.
