Trial 1: The Verbatim Race
Attempt to write down every single word the teacher says. Do not skip anything!
How did it feel?
When did you stop?
Analyzing the Bottleneck
Your "Working Memory" is like a narrow tube. Too much information at once causes a clog.
1. Input
Spoken words, sounds, pacing
2. Processing
The "Working Memory" Bottleneck
3. Output
Written notes, drawings, connections
What happens to your brain when the speaker goes too fast for you to write every word?
If you can't write every word, what should you prioritize capturing instead?
Exact vocabulary
Relationships between ideas
Filler words (like "and" or "the")
The "Big Picture" goals
Bottleneck Intro Slides The Working Memory
Bottleneck
Visual Note-Taking Lesson 1
Today's Mission
Understand the Limit
Discover why our brains can't write as fast as people talk.
Shift Your Focus
Learn to stop listening for "words" and start listening for "meanings."
"Your brain is for having ideas, not holding them."
The Memory Pipeline
1. EAR
Information enters as sound
Working Memory
THE BOTTLENECK
Where info is held briefly before it's lost or saved.
3. PAGE
Information is "Externalized"
Why Verbatim Fails
Too Fast
Most people speak at 150 words per minute. Most students write at 30 words per minute.
Zero Context
Focusing on letters prevents you from understanding the actual story or logic.
THE SOLUTION
Visual Notes = Compressed Data
Instead of writing every word, we build a map of the ideas.

Lesson 1: The Bottleneck Challenge
The Hook: The Impossible Dictation
Before explaining working memory, force students to experience its failure. This creates "buy-in" for the strategies they will learn later.
Instructional Script:
"Okay everyone, get your pens ready. I am going to read a short passage. Your only job is to write down EVERY SINGLE WORD I say. If you miss a word, keep going. Ready? Go."
Reading Passage (Read VERY FAST, approx. 180wpm):
"The process of cellular respiration is fundamentally the mechanism by which biological organisms convert biochemical energy from nutrients into adenosine triphosphate or ATP and then release waste products the reactions involved in respiration are catabolic reactions which break large molecules into smaller ones releasing energy because weak high-energy bonds are replaced by stronger bonds in the products."
Discussion Questions
At what point did you give up?
What did it feel like in your head when you fell behind?
Can you explain what "cellular respiration" is based on what I just read? (Most will say no).
Key Takeaways
Transcription ≠ Understanding.
Speed is the enemy of retention.
We need a system that doesn't rely on word-for-word capture.
Explanation: The 7 ± 2 Rule
Explain to students that human working memory can typically only hold between 5 and 9 pieces of information at once (Miller's Law). When we try to write every word, each *letter* or *word* takes up one of those precious slots.
What Clogs the Bottleneck:
Focusing on spelling
Worrying about neat handwriting
Capturing "filler" words (and, the, of)
Trying to keep a perfect line-by-line list
What Bypasses the Bottleneck:
Using icons (pictures process faster than text)
Using spatial relationships (position = meaning)
Summarizing whole sentences into one symbol
Pre-segmenting the page (reduces decision load)

Pick Your Blueprint
The Quadrant
Best for: Comparing 4 different sub-topics at once.
Modified Cornell
Best for: Main ideas on the left, details on the right.
The T-Bone
Best for: One big summary at top, two categories below.
Reduce "Decision Fatigue"
If you are thinking about WHERE to write,
Strategy: Name your buckets BEFORE the speaker starts talking.

Active Listening Challenge: TED Talk Practice

STEP 1: Preparation
The speaker is going to talk about "The 3 Secrets of Sleep." Based on that title, we can pre-label our page segments.
Secret 1
Secret 2
Secret 3
SECRET 1:
SECRET 2:
SECRET 3:
THE BIG WHY (Core Message):
? QUESTIONS:
Layout Analysis
Did having pre-labeled boxes make it easier to decide where to write? Why or why not?
What happened if the speaker started talking about "Secret 3" before you finished "Secret 1"? How did the layout help you handle that jump?

The Magic of Connectors
Static Link (X and Y)
Cause/Effect (X leads to Y)
Parallel (X and Y at same time)
PRO TIP:
Spatial placement is also a connector. Putting something under something else can mean it's a detail or a foundation.

Reflection: The Working Memory Win
How did it feel different to "draw the logic" compared to the first verbatim challenge in Lesson 1? Was your brain less "clogged"?

How to Use Visual Notes
1
The "Cover Up"
Cover a section of your notes with your hand. Look only at the ICON.
2
The "Oral Relay"
Try to explain the concept out loud using only the visual cues. If you can't, uncover and re-read.
Mental Retrieval
"Making your brain work to find the answer makes the memory stronger."
Metacognition
"Thinking about your thinking"
Ask Yourself:
Which layout felt most natural?
Which icons were easiest to remember?
Where did I still struggle to keep up?
The Goal:
Build a Personalized Note-Taking System that supports YOUR working memory.
"There is no 'right' way to sketch. There is only 'your' way to remember."
