10 Tips to Study Smart and Save Time
Building an Understanding
Learning
is a process similar to building a house. You aren’t fed the complete
picture. Limitations on communication prevent the instantaneous
transmission of knowledge. Instead you listen to lectures, read
textbooks and take painstaking notes to try and comprehend a subject.
You
are fed building supplies, bricks, mortar and glass. It is up to you
to assemble the building. Unfortunately, most learning strategies fall
into two basic types:
- Memorization – Instead of building anything you simply stare at each brick for several minutes trying to record its position.
- Formulas
– This is the equivalent to being blind, fumbling around a new house.
You can’t see the building itself but you learn to come up with simple
rules to avoid walking into walls.
There is nothing
particularly wrong with either of these strategies, assuming they aren’t
your entire strategy. The human brain isn’t a computer
so it can’t memorize infinite sums of knowledge without some form of
structure. And formulas no longer work if the questions they are
designed to solve change scope.
- Learning Holistically – The
alternative strategy is to focus on actually using the information you
have to build something. This involves linking concepts together and
compressing information so it fits in the bigger picture. Here are some
ideas to get started:
- Metaphor – Metaphors
can allow you to quickly organize information by comparing a complex
idea to a simple one. When you find relationships between information,
come up with analogies to increase your understanding. Compare neurons
with waves on a string. Make metaphors comparing parts of a brain with
sections of your computer.
- Use All Your Senses – Abstract ideas are difficult to memorize because they are far removed
from our senses. Shift them closer by coming up with vivid pictures,
feelings and images that relate information together. When I learned
how to do a determinant of a matrix, I remembered the pattern by
visualizing my hands moving through the numbers, one adding and one
subtracting.
- Teach It – Find someone who
doesn’t understand the topic and teach it to them. This exercise forces
you to organize. Spending five minutes explaining a concept can save
you an hour of combined studying for the same effect.
- Leave No Islands
– When you read through a textbook, every piece of information should
connect with something else you have learned. Fast learners do this
automatically, but if you leave islands of information, you won’t be
able to reach them during a test.
- Test Your Mobility -
A good way to know you haven’t linked enough is that you can’t move
between concepts. Open up a word document and start explaining the
subject you are working with. If you can’t jump between sections,
referencing one idea to help explain another, you won’t be able to think
through the connections during a test.
- Find Patterns
– Look for patterns in information. Information becomes easier to
organize if you can identify broader patterns that are similar across
different topics. The way a neuron fires has similarities to “if”
statements in programming languages.
- Build a Large Foundation -
Reading lots and having a general understanding of many topics gives
you a lot more flexibility in finding patterns and metaphors in new
topics. The more you already know, the easier it is to learn.
- Don’t Force -
I don’t spend much time studying before exams. Forcing information
during the last few days is incredibly inefficient. Instead try to
slowly interlink ideas as they come to you so studying becomes a quick
recap rather than a first attempt at learning.
- Build Models
– Models are simple concepts that aren’t true by themselves, but are
useful for describing abstract ideas. Crystallizing one particular
mental image or experience can create a model you can reference when
trying to understand. When I was trying to tackle the concept of
subspaces, I visualized a blue background with a red plane going through
it. This isn’t an entirely accurate representation of what a subspace
is, but it created a workable image for future ideas.
- Learning is in Your Head
– Having beautiful notes and a perfectly highlighted textbook doesn’t
matter if you don’t understand the information in it. Your only goal is
to understand the information so it will stick with you for
assignments, tests and life. Don’t be afraid to get messy when
scrawling out ideas on paper and connecting them in your head. Use
notes and books as a medium for learning rather than an end result.
