| A
useful visual prompt/aid for investigation. Key variables are selected
along with the dependant variable. Basic modelling allows positive
and negative correlations to be selected to allow a prediction to
be decided upon. The key variable is selected and the tables and graph
set up is automatically determined. |
The
aid shows an ammeter with a series of shunt/socket options. The needle
can be dragged to any point so that students can learn how to read
standard analogue ammeters. |
A
drag and drop graph plotting program. The scale can be set, the
axes labelled and then points dragged onto the graph. Lines (or
curves) of best fit may then be manually applied. This is an interactive
aid to teach graph plotting skills.
