Tips for using Doodle Diagrams as Guided Notes
The thing that most students struggle with in middle school and high school, in every class, is how to
take notes. So often, they are lost without some sort of model. Many teachers expect them to
have a blank notebook page, watch a Powerpoint, listen to the teacher lecture, somehow know
what is important enough to write down, and physically write while trying to listen. This is mentally
exhausting and so often students struggle all year, year after year, doing the same thing. A
friend of mine used to call this teaching style: “Death by Powerpoint”. Students benefit by taking
notes, by physically writing, but there has to be a balance and there has to be a model for them to
follow.
I have found in the past that the best way to help students take notes is to give them a notes
packet for each unit with headers and a list of topics I’m going to cover in class: basically a space
where they can put their notes on the page. Every year, I have improved my notes packets and
class discussions to better help my students learn without being overwhelmed while taking notes.
I’m creating these doodle diagrams so that students have pictures to help them really visualize
each concept in their notes.
What I find helps students the most when I am helping them to learn content together in a class
discussion format:
* I decide which note format would be best for my students. I have pages with more or less text,
so I can customize it for each student or class depending on their ability to take notes and how
much time I want to spend. Some students/classes really like to draw their own pictures; some
don’t!
* I print and copy a packet of the unit’s doodle diagrams and have them stapled before I give
them to my students. Students are much less likely to lose a packet and they are more likely to get
the notes when they are absent from a friend, because they see that it’s blank in their packet!
* Give them a model to follow! Write as you go, with them on an ELMO projector, so they can see
what you’re writing, what you’re highlighting, how you want them to take notes and process the
information.
* Use Powerpoint minimally. I do use my computer projector to show pictures or short video clips
or other multimedia that I find online to supplement the guided notes. I use very little text on the
screen.
* I encourage students to doodle! These pages are designed to have places where students can
fill in borders, fill in letters, color in pictures, and make their own doodles in the white space.
Research shows that students who do this remember more of the material! Processing the
material with the artistic side of their brain can aid in memory. So encourage them to use colored
pencils, pens, whatever they would like on their page in the time you working through the page with
them.
© Bethany Lau
* As I go through the lesson, I never just fill in the blank on the doodle diagram. I ask questions
continually. I ask students what they think are the characteristics of life, what they think will
happen next in this diagram, what they think is the best way to summarize this video clip they just
saw on transcription or translation. And we fill it in together.
Teacher Tips for Intro to Punnett Squares:

Mendel’s peas, hybrids, true-breeding, genotype, and phenotype.

2. One important thing to stress: each genetics problem asks
for a different type of answer. Some ask for genotype and
phenotype ratios. Some ask for the percentage of offspring
with one particular genotype or phenotype. It’s important
for students to ANSWER the question.
© Bethany Lau
I recommend
talking about
ratios,
percentages, and
fractions in the
way you want
your students to
answer questions.
Example Genetic Cross:
A heterozygous tall pea plant is crossed to
another heterozygous tall plant. Tall is dominant
over short. Calculate the phenoty pe and
genoty pe ratios of their offspring.

steps 1-6, are the

students
consistently take
while they solve
their genetics
problems.
Teacher Tips for Word Problem Clues
I use this page after I’ve taught students about Punnett squares for my basic and
regular students. Sometimes I find identifying the parent genotypes or figuring out
which allele is dominant is the hardest part of the problem! Students need to know what
the word clues are to determine how to set up the problem.

Because the young fish has stripes and its mother was

homozygous for the recessive trait (spots), you can tell
that the young fish is a heterozygote. It must have

dominant over spots.
What is the genoty pe of the
young striped zebrafish?
Ss (S for striped)
“Hybrid”
“Hybrid” means
heterozygous. In this
example, because the
heterozygote shows
the dominant trait,
brown hair is the
dominant trait.
“True-breeding”
A true breeding brown bodied male fly mates
with a white-bodied female fly. The brown body
allele is dominant over the white body allele.
(Use B for brown and b for white)
An albino male mouse is mated with
a hybrid brown-haired female
mouse.
What is the genoty pe of the
female parent?
Bb (B for brown hair)
“True
-breeding”
means
homozygous.
What is the genoty pe of the male parent fly?
BB
To figure out which allele is
Dominant or Recessive?

phenoty pe of a heterozygous

different word
clues that can
really help
students figure
out a problem.
Teacher Tips for Test Cross
The test cross comes up a lot in genetics problems but so often students don’t
understand WHY a scientist would use a test cross.
The scientist
crosses that
organism with a
homozygous
recessive
individual and if
any of the
multiple progeny
has the recessive
phenotype, the
original mystery
individual was a
heterozygote.
In goldfish, there is a trait caused by a
dominant allele in a developmental gene called
bubble-eye.
* Bubble eyed goldfish have a large bubble-like
sac near each eye and they lack a dorsal fin.
Bubble
eye
Normal
eye
* Normal eyes (b) is recessive to bubble eyes (B).

What are their genoty pes?
The normal eyed fish’s genoty pe must
be bb because normal eyes is recessive.
The bubble eyed fish’s genoty pe could be BB
or Bb. You cannot tell by looking at it!

Teacher Instructions:
I recommend using these “exit tickets” for the last
3-5 minutes of class. Pass them out, ask your
students to fill them out, and then go over the
answer right then and there after they switch with
their partner to correct. I recommend having the
“partner switch” be different every day (Behind you,
in front of you, to the left/right etc). That way you
can give them a participation grade by just checking
them off in your gradebook (I’m sure you don’t have
time to grade 100+ of these a day...) It’s a great
way to get a quick formative assessment of how
they understood the lesson.
