Classroom use in Courses and Topics:
Algebra: Graphing Quadratics
Duration of classroom use:
One Class
What did students learn?
I used Function Flyer to demonstrate the role of "a" in the vertex form of a quadratic function, f(x) = a(x - h)^2 + k.
What did students do with the resource?
Observed
How hard was it for students to use?
Very Easy
Other classroom comments:
Students liked the slider.
Appropriate for:
introduction to a concept, applications of a concept or technique
Other Comments:
I put the cursor one unit to the side of the vertex of the parabola, and observed that the y-coordinate was "a" away from the y-coordinate of the vertex.
What math does one need to know to use the resource?
How to write functions algebraically
What hardware expertise does one need to learn to use the resource?
None
What extra things must be done to make it work?
Nothing
How hard was it for you to learn?
Very Easy
Explanation:
To obtain a slider, just type in 1 (or any number) as a coefficient. The applet automatically interprets any numerical parameter as a slider.
Ability to meet my goals:
Effective
