Tests are meant to measure progress
-
towards gaining practical skills or understanding ideas.
-
Their purpose is to show teachers and students
-
what went right
-
and what went wrong.
-
Unfortunately, too many times
-
we fail to act upon what tests find out.
-
Instead of fixing the gaps that tests identify,
-
students are pushed through the school system with
-
poor test results and bad grades.
-
The problem is that if we fail to fill these gaps,
-
school can become years of boredom
-
and potentially clever kids
-
might lose faith in their own abilities.
-
Most Multiple Choice Tests for example
-
are designed to reward guessing
-
instead of precision and honesty.
-
They do not give us the option to “not know”.
-
With terrible consequences.
-
After the test has been taken,
-
both teachers and students
-
won't know whether the student got it,
-
or just guessed it right.
-
This sends the wrong signal
-
and we miss the opportunity to fill knowledge gaps.
-
Mastery Learning,
-
an educational philosophy first proposed
-
by Benjamin Bloom in 1968, offers a solution.
-
Under Mastery Learning students must achieve a level of excellence
-
(which could be. 90% on a math test)
-
before moving forward.
-
If students do not achieve mastery on the test,
-
they go back to study and then get tested again.
-
This cycle continues until the student gets it right.
-
Only then may they move on to learn the next thing.
-
In 2011 the Khan Academy,
-
a non-profit organisation,
-
and the Los Altos school district
-
showed that great things happen
-
if math students advance
-
only if they fully understand a concept.
-
Six months into the experiment of passing only students
-
that fully mastered a concept,
-
the number of advanced math students doubled
-
and 6% of the weakest group
-
joined those at the very top.
-
What do you think?
-
Does it make sense to teach a student
-
who doesn't understand 8 times 3 equals 24,
-
how one sixth of 24 equals 4?
-
It's almost like saying:
-
you don't know how to swim in a pool?
-
what the heck try and jump into that river!
