Reflection: Complex Tasks Using IVCDV Charts - Section 1: Introducing Variables

 

The IVCDV chart turns a difficult tasks into a more manageable one by giving students a structure to organize their thoughts and plan investigations.  I think that the separation of the independent and dependent variables by the constants helps students see that if you change the IV and keep everything else constant that the DV is based on the IV only.  Stating this to the students helps them remember that IV is what "I am changing" and fits in nicely when setting up a hypothesis.  The IV is always stated followed by the dependent variable.  If "I change this (IV), then "this will happen (DV)."  Using the chart alleviates confusion and supports student learning.
