Bracha Alpert has identified three different patterns of classroom discourse: (1) silent (the teacher talks almost all the time and asks only an occasional question),(2) controlled (as in the excerpt above), and (3) active (the teacher facilitates while the students talk primarily to each other).
A fractal is a never-ending pattern. Fractals are infinitely complex patterns that are self-similar across different scales. They are created by repeating a simple process over and over in an ongoing feedback loop. Driven by recursion, fractals are images of dynamic systems â the pictures of Chaos. Geometrically, they exist in between our familiar dimensions. Fractal patterns are extremely familiar, since nature is full of fractals. For instance: trees, rivers, coastlines, mountains, clouds, seashells, hurricanes, etc. Abstract fractals â such as the Mandelbrot Set â can be generated by a computer calculating a simple equation over and over.
