Problems understanding math |
2008-07-27 |
|
From Cindy:
why do so many people have problems understanding math.
is it because at some point along the way they didn't fully understand
a concept and they then lose confidence. Learning math is cummulative so what you
don't learn at one point just gets more confusing as you move along. how do
we correct this? how can i help students in junior and senior high who do poorly in math.
