Whether or not you can teach something as subjective as critical thinking has been up for debate, but a fascinating new study
shows that it’s actually quite possible. Experiments performed by
Stanford's Department of Physics and Graduate School of Education
demonstrate that students can be instructed to think more critically.
It’s difficult to overstate the importance of
critical-thinking skills in modern society. The ability to decipher
information and interpret it, offering creative solutions, is in direct
relation to our intellect.
The study took two groups of students in an
introductory physics laboratory course, with one group (known as the
experimental group) given the instruction to use quantitative
comparisons between datasets and the other group given no instruction
(the control group). Comparing data in a scientific manner; that is,
being able to measure one’s observations in a statistical or
mathematical way, led to interesting results for the experimental group.
Even after these instructions were removed, they were
12 times more likely to offer creative solutions to improve the
experimental methods being used in the class, four times more likely to
explain the limitations of the methods, and better at explaining their
reasoning than the control group. The results remained consistent even
in the next year, with students in a different class. So what does this
imply about critical thinking, and how can we utilize these findings to
improve ourselves and our society?
We live in an age with unprecedented access to
information. Whether you are contributing to an entry on Wikipedia or
reading a meme that has no sources cited (do they ever?), your ability
to comprehend what you are reading and weigh it is a constant and
consistent need. That is why it is so imperative that we have sharp
critical-thinking skills. Also, if you don’t use them, you will have
nothing to argue with your family about at Thanksgiving. More
importantly, it keeps your brain from nomming on junk food and on more
of a kale-based diet. Look at any trending topic, and test yourself. Is
this true/accurate? How do I know either way? Is there a way I can use
data (provable, factual information) to figure this out?
Certainly, we can train ourselves to become better critical
thinkers, but it’s also important that we teach these skills to kids. Studies have shown how important this ability is to our success, and yet many feel that we’re doing a terrible job of teaching it.
This study, however, may lead to educators and parents realizing that
these skills are teachable. The implications of a better thinking
society are not quantitative, but I do believe they would be
extraordinary.
