Achtergrond

  • ESM, march 2014:

Alnuset includes three connected representational environments: a one-dimensional number line, an algebraic manipulation toolkit, and a two-dimensional Cartesian plane. Users can explore algebraic expressions and functions and their component parts in the context of these number lines by defining parameters that can be dragged along the line and expressions involving those parameters that adjust automatically. Number line, symbolic/algebraic expressions, equations/inequalities, Cartesian graphs, and propositions are standard, but the complex operations and combinations of operations, along with its dynamism, make this number line a quite innovative system of representation
