Let us know what you think…
I would love to use this to teach angles. Hands could be the end of rays with realtime angle measurements.
Thoughts after our first hands on demo in Wenatchee.
First, great job. This is cool.
Some things we were wondering about:
1: Can we enter an equation to graph?
2: Can we see the different forms of an equation (ie factored and standard forms of the vertex form)?
3: could we lock different parts of the equations (such as the a, h, or k of the vertex form)?
4: Could we control the scales on the x and/or y axis?
5: Could we graph into all 4 quadrants?
6: Could we utilize the 2 person tracking capabilities of the kinect?
7: Eventually could we use polygons?
I know I’m forgetting some, but again, it’s cool to see something like this and be involved. Thanks.
There are at least two things that I would love to see added.
The first is a tangent function, so that we can manipulate it as well.
The second is being able to change the x-axis values to degrees and radians when discussing the period of the a sine, cosine, or tangent function.
A few things that would be nice to see are;
When more than one function are graphed could there be a point showing where the two intersect?
Some way to integrate it with geometry software such as geogebra so that that we can manipulate shapes with our hand and interact with more geometric concepts.
The ability to enter your own equations into the program.
I’m very impressed with the start you have made and grateful for the opportunity to use and help in hte development of this tool.
I look forward to seeing other functions available, such as absolute value, radical, and exponential functions. It looks like an awesome tool for demonstrating how basic operations affect tranformations on graphs of functions.
What fun in the demo Friday afternoon in Wenatchee! And what a great way to take one outside of self-awareness about physical movement!!
The graphing would be even more useful if functions were allowed to graph beyond the first quadrant. Once we figured out how to “iterate” to obtain steeper slopes for line functions, it became even more clear that functions should extend beyond the y-axis.
Being able to determine coordinates of points of intersection would be great for looking at systems of equations, points of tangency (sp?). At this point, one can travel along a funtion and get a read out, but we still have to estimate the overlap.
Thanks so much for developing this!
Would it be possible to have the editing mode with the equation showing be able to graph the equation to the left of the y-axis? It would be great to be able to use all 4 quadrants of the coordinate plane?
Awesome tool guys.
-I would like to see when you bring up the table and highlight a coordinate pair (X,Y) that it highlights that point in the graph like fathom. does.
-Is there a way to do two lines)(linear graphs) at once with two people making the graph.
-It would be a neat tool if you could graph inequalites and the shaded regions show up when you put your hand in the correct area.
Thanks for creating a great teaching tool for us and our students.
Something else that came to mind when reading all of these and thinking back would be to have it recognize that there are 4 angles created at an intersection of 2 lines. Would it be possible then to have an option to show one, some or all of those angles? To make them dynamic so that as I manipulate lines, the angle(s) I select will change accordingly?
Could there also be a segment and/or ray ability rather than just lines which would come with the ability to designate points (maybe by voice)? This could also then have the ability to work with triangles by connecting segments? If we could designate and manipulate points, could a distance function be built in to show lengths of segments?
the more we get into this, the more we see. Again, great job.
Would adding a stopwatch/timer somewhere on the screen as a person is walking/mimicking a line be possible?
Another thing that would be nice would be the ability to toggle on and off grid lines.
I enjoyed using the kinect box with my fellow sixth grade teachers last week in Wenatchee and I look forward to using it on our graphing unit. On Monday I sent an email to the tech dept. asking if it would be possible to obtain a laptop that would work with the xbox 360. Which is my feedback, I guess. Until my school district provides the means to use this technology, I won’t be able to. I will continue pursuing the laptop, and keep Robin and Keri posted. Thanks again, MG
Great ideas TJ!!!
I love this program!
Two more things I would like to see:
1) Parabolas in factored and general form
2) Calculation of area under the velocity curve
Any chance there will be an update that allows to to play with and measure angles?
I was in the process of using this in my classroom today (3/24). The tool works great. I only have one issue. In the vertex form for quadratic functions, the sign in front of the h should be the opposite of what it is showing. For example, the parabola starts of at y=1(x+1)^2 +1. According the to equation, the vertex would be (-1,1), however, on the graph it shows the vertex to be (1,1).
