Misunderstood words

• These are words heard or read that the mind does
  not fully comprehend.

They sent us small quantities of unununium but
their apatite was quite large.
Poor man stutters, and why do we care about their
apetite?

Misunderstood words

• How do you know if a misunderstood word has been
  encountered?

• The Mind goes blank

Let me tell you about my theory of relativity

Misunderstood words

• How do you know if a misunderstood word has been
  encountered?

• The Mind goes blank

• Have you ever been reading a book and got to the
  bottom of the page and realized you dont
  remember a word you just read?
• You have likely passed a misunderstood word that
  caused your mind to shut down.

5
What other symptoms are there from misunderstood
words?
Check the patients chart for rubs, crackles, and
snaps.

• Theres a feeling of being dumb and not
  belonging.
• For example, when words are used that someone
  doesnt understand, that person can feel stupid
  and feel like fleeing.

None of those but S2 gallop, innocent murmur, and
a dim A2 were present.
6
What symptoms should teachers or students look
for in the classroom ?

• Experiencing misunderstood words can make people
  irritable and prone to complaining.

• They usually end up disliking or hating the
  subject.

7
So how do you avoid the barrier of misunderstood
words?

• Recognize the symptoms

Irritable
Mind is Blank
Feeling dumb not belonging
Disgusted
8
So how do you avoid the barrier of misunderstood
words?

• Look up words as soon as possible (dont guess
  their meaning)
• Use the dictionary ( online ones) for even
  technical terms. Learn the origin of words.
• Surf the internet for moreinformation

Learning at too steep of a pace
A more gradual approach gets farther
Too steep of a pace
11
Learning at too steep of a pace

• If learning is done in a step by step fashion, it
  is easy.

12
Learning at too steep of a pace

• If steps are skipped, then there is a complaint
  that a certain step is too difficult.

13
Learning at too steep of a pace

• How do you get past this barrier?
• Return to the step you were doing well and then
  proceed by making sure you do each step.

15
Lack of Visuals or Hands-on Learning

• For most subjects, the lack of visuals or
  hands-on learning keeps people from seeing or
  grasping the material.

What are the symptoms from not having enough
visuals or hands-on learning?
1. Headache (from straining to visualize what is
being discussed).
16
Other symptoms?

• 2. Eyes may hurt(Probably from strain from
  continuous reading and trying to visualize the
  subject.)

17
Other symptoms?

• 3. Heavy, weighted down feeling (Probably from
  accumulation of vague, incomplete images kept in
  the mind)

18
How can one avoid this barrier?

• FIND PICTURESThe Internet is one good source.

19
How can one avoid this barrier?

• Find movies, videos, or TV programs that relate
  to the subject.

20
How can one avoid this barrier?

• DRAW PICTURES
• Do what artists and designers do draw pictures
  either freehand or with the help of the computer.

21
How can one avoid this barrier?

• CREATE OR FIND MODELSOR FIND THE REAL THING

Clay is an excellent choice for
making3-diminension models of items or concepts.
Studying the real thing is the best.
Take a tip from engineers. They use models to
help them understand.

Chemistry is observed on two levels. One level is
what can be sensed with human senses. The other
level is below human eyesight, smell, touch,
hearing, or taste. Instruments expanded what we
could sense and therefore we learned more and
faster.

"My work, which I've done for a long time, was
not pursued in order to gain the praise I now
enjoy, but chiefly from a craving after
knowledge, which I notice resides in me more than
in most other men. ...whenever I found out
anything remarkable, I have thought it my duty to
put down my discovery on paper, so that all
ingenious people might be informed thereof." -
Anton Van Leeuwenhoek Letter of June 12,
1716. Leeuwenhoek constructed a total of 400
microscopes during his prolific lifetime.

The language of chemistry is difficult for
several reasons Many words are based in
Latin Pb for Lead because Latin Plumbum Many
words are named after dead scientists Fahrenheit
Many words are polysyllabic d-alpha-tocopherol
(Vitamin E) Some compounds have multiple
names ethanol, grain alcohol, fermentation
alcohol, alcohol, methylcarbinol, ethyl alcohol,
absolute ethanol, anhydrous alcohol, alcohol
dehydrated, algrain, anhydrol, Cologne spirit,
ethyl hydrate, ethyl hydroxide, jaysol, molasses
alcohol, potato alcohol, spirits of wine, spirit,
tecsol

Tips on learning words
Learn where the words came from. It helps you
understand the meaning It helps you remember
it Connect the chemistry words to other
subjects. This reinforces the meaning and helps
you recall it. (cyan cyanide cyanosis
cyanobacterium) Connect the words to as many
senses as possible. See, hear, smell, taste, and
touch
61
Tips on learning words
Break words into their parts (prefix, word root,
suffix) This simplifies the word Knowing the
parts will help with new words (trinitrotoluene)
Make the word more real by drawing it, making a
model, or finding pictures that relate to it.
