Factual Thinking
v. Integrative Thinking,
or How We Need To Teach Science
What is “thinking”?
This question has
many different answers.
We can talk about
thinking as a process, as a function, as an ability.
But no matter what
feature of thinking we discuss, we always run into a discussion about its
structure.
Thinking has a
structure, it has elements, connections, rules – the simplest way to see it is
to consider such important type of thinking as logical reasoning.
A science teacher
does not need to know all of that (but must read at least one book on psychology
of thinking).
But a science
teacher definitely needs to know the difference between factual thinking and
integrative thinking.
If I ask a
question to a student:
1. What is the
direction of electric current in a wire connected to a battery (providing a
picture)?
or
2. How to calculate
force of gravity acting on an object with a given mass?
or
3. How to find a
direction of a force acting on a wire with electric current when it is placed
in a magnetic field (providing a picture)?
or
4. How to calculate
the magnitude of a force acting on a wire with electric current placed in a
magnetic field?
or
5. How to calculate
the value of electric current in a wire with a given resistance when it is
connected to a battery with a given EMF?
For each of those
questions a student either gives me a correct answer or not.
If a student
cannot answer correctly, he or she has not been doing a good study of the material.
But if a student
gives correct answers to all five questions, does it mean he or she understand physics?
To test the understanding of a student I can give him/her a problem:
A problem
A wire with a given mass, resistance and length and connected to a known battery is placed in a magnetic field and, when released, hovers in it (floats in the air). Draw the circuit, draw the picture, draw the FBD (free-body-diagram), make natural assumptions and calculate the strength of the magnetic field.

Now a student does
not have to answer five different questions; now he or she has to use his/her
factual knowledge in a specific manner.
Memorizing and retrieving
answers to questions about facts, rules, laws involves and demonstrates factual
thinking.
Using those answers
to factual questions for solving a complex problem requires a specific mental work
- when all factual knowledge gets connected and integrated in one specific
logical construct.
This is why I always say to my students that thinking is kind of like knitting.
This process involves and demonstrates integrative thinking.

Integrative
thinking is the essence of scientific thinking.
When a science
teacher focuses solely or mostly on factual knowledge, students do not learn science.
It is a common
misconception that science classes are about learning scientific facts, rules,
laws.
No, it is not.
Learning scientific
facts, rules, laws is no different from learning religious facts, rules, laws.
In both cases the answer
to question “why” is the same – “because I said so”.
The difference between
science and religion is much deeper.
The goal of a
science teacher is to teach students not just scientific facts, but most and
foremost is how have scientist come up with those facts, how did they got to know
all that scientific stuff.
Integrative
thinking is what future scientists need to have.
The goal of a science course is to help students with development of scientific thinking.
But in order for students to have that type of thinking be developed, their teachers must possess that type of thinking as well, and most importantly, their teachers must teach students how to think in that specific way.

Unfortunately, the
current forms of teacher professional development do not help teachers with the
development of their integrative thinking, they also concentrate on factual thinking
providing teachers with a list of new facts.
Nowadays we have
an additional confirmation of the importance of integrative thinking – it comes
from neurology.
The property of a brain
called neuroplasticity basically means that a brain functions in a way similar to
any physical muscle – you train it, and it gets trained, you do not train it and
it gets atrophic.
Advanced thinking requires advanced brain.

That is why I like
using this example (comes
from part II of this post): “If the only exercise students had been doing for twelve
years is squats, they will not be good at push-ups and pull-ups. Do not expect from
students an ability to think if all they had to do for twelve years was
memorizing facts and rules” (one of many laws from "Laws of
TeachOlogy").
Several other post on the matter; they look like they are about physics, but one can replace “physics” with “science” and everything remains correct:
And specifically on
the
page for the strategies of teaching science:
The
mission (i.e.
the reason for existence) of
education
as human practice is to ensure the progress of humanity.
as human practice is to ensure the progress of humanity.
The
mission of
education as
social institution
is
enabling people to succeed
in life.
The
goal of educational
institutions
is to equip people with relevant knowledge and
skills.
The main function of
educational institutions is
Teaching: i.e. guiding
students through an arrangement of learning experiences specifically designed
for helping students with mastering subjects, acquiring relevant social skills,
and feeling good about themselves.
The
mission (i.e. the reason for existence) of science as a human practice is making
reliable predictions.
The
mission of a
scientist as
an agent of that practice is discovering truth and presenting it in a
testable form.
The
mission of a
teacher is
fostering in students his/her love for learning.
The
mission of a
science teacher is
sharing with students the feeling of pleasure from thinking.
The
mission of a
mentor is sharing with students the feeling of pleasure
from doing the right thing.
The
mission of a
parent is making children
feeling safe, loved, and confident.
The
mission of humanity is making world a better place
