This clip shows the possibilities of NXT WOW. I spent several hours trying to improve my understanding of PID Control. After quitting last night, however, I refocused on the human intelligence. What can we learn from kids who have developed these kinesthetic skills that will help us to help all students to achieve at high levels?

Note the much greater complexity than the solution that Barello describes in his version of the GyroBot. Perhaps we can derive insight from this demonstration to see how to implement an easier solution. Also note that Mathematica even provides a free viewer tool that allows an intermediate level of access to the model.

Frau Adams invited students in her 8th grade German class to submit weather projects in multimedia formats of students' personal preferences. Ariel and Laurel chose to extend their work with the green screen in ITeam for this assignment. Here, they set up to share their production with their class. I wanted to submit a brief video clip of their presentation to the class but Blogger would not accept the video file submitted this way as described here and here.
This image comes from the camera album in the gallery.
This method does not require the end termination. I also needed to add tags manually.
The AndroidLegoRemote video. It did not take the video.
Now trying a jpg image. And a tag escape.
And none of the signature stuff after an end command. The end command worked as described in help but my attempt to probe the system for undocumented functionality did not produce the desired result:
I needed to add the labels to the post manually.

I have been trying to locate one of my videos of this subject on my MLTI laptop and it is anything but straightforward. I can easily find and view the video I want but so far, I cannot get the file url into the upload tool.
By using the "Save for Web" item under the file menu of QuickTime, I was able to create and find the file for upload. While that convoluted process might have sufficed in the past, it doesn't encourage routine use. What can we do to facilitate easier use?

I wonder if some of the seniors that are doing pre-pilot projects might be available. They face some similar challenges but might be willing to come for part of the day and recruit a collaborator who would bring valuable perspectives, too.
Sunday evening they returned access to our work with a request to revise before they will accept it. The reviewer suggested that we add some video to our contribution.
Deed Needs RevisionsThe deed you submitted for the mission "Knowledge Swap" needs some more work before it can be approved. You can keep working on it and submit it again at any time.
Here's what you need to work on:
This is very cool and we want to accept the deed -- but I think it can be much more illuminating to the community if you also upload a little video of what you're doing. Is that possible? We'll give you more points if you do so. Thanks!
So, I am saving it here as part of our development process and evaluation.
"Ariel M. and I worked together combining her knowledge of NXT and mine of AppInventor"
I am developing experience with AppInventor and track the new features as they are released. When I saw that Liz Looney was developing AppInventor support for NXT robotics, I anticipated that this would be highly engaging for ITeam members.
Ariel uses NXT robotics outside of school. She showed me how to use the NXT module and test a variety of sensors. For example, she used the ultrasonic distance sensor to determine its range (~1 to 90 inches). We connected it to math by measuring the maximum distance and comparing it with the distance we measured (as 7.5 x 12" tiles on the floor outside he library).
We could make an even more engaged connection with STEM by conducting a more complete comparison of observed (sensor) with measured (tape measure) distances and plotting those for analysis and interpretation. Once ITeam members are sufficiently familiar with the tools, we may be able to help MAMS sixth-grade teachers and Ms. Hogan, the technology integrator, incorporate ideas into the force and motion unit that they are developing.
We were able to connect the phone to the NXT Bluetooth and control both the tone generation and a test motor! Ariel was sufficiently excited that she started building the robot described in the NXT instructions booklet.
12/10/10- Today we worked on adding another motor to the robot. We also took some pictures of what we were doing. Hopefully by next week we will have the motors put together and many more pictures.

I learned about ?! (InterroBang: http://playinterrobang.com/) through a message that Jim Matthews posted on the ARISgames group (http://groups.google.com/
Stephen Spaeth [Note that this link will not take most users to the right page because you need to have an account to get access to this page.] Ariel joined our team and contributed to documenting the deed. She took the picture, wrote the caption, and added text to describe the continuing work we did today. She decided that we were ready to submit the mission and hit the button. Apparently, it takes the deed out of our hands and we no longer have access to the deed. I can understand the need to freeze it during the approval process but I'd still like to be able to see the preview. It is unnerving to loose control over our own creation.As more time elapses, it becomes clearer that providers of this service need to:
about 18 hours ago
- Make the time-frame for approval process clearer
- Make it clear to users that they will loose access to their own creations
- Add the option to cross-post entries to other venues (e. g. to this blog for me) or at least the option to make the entry publicly accessible
Update: AppInventor developers and beta users are cranking out useful resources almost every day. For example, Liz Looney shared ShinyLegoNxt, a new source file to demonstrate the new NXT resources.

Thank you for making time in your schedule to participate (even briefly) in the capstone meeting today. I thought that your part added much to the deliberations. Your story about rebuilding a motorcycle resonated with me because my brother's student initiated learning project consisted of 3 or 4 years dedicated to rebuilding two Model A Fords.Students have wanted more engaging learning experiences for a long time. But only the most persistent and/or well-supported have been able to do substantial interest-based project and connect them with their school experiences. How can we make it possible for all students to get the benefit of doing the "hard fun" of something they want to learn?
