READABILITY
The readability of a textbook
involves the determination of an
approximate grade level at which
materials are written.
READABILITY FORMULAS
• Fry Readability Graph
- Based on length of sentences and number of syllables in a selection
http://school.discovery.com/schrockguide/fry/fry.html
• McLaughlin’s SMOG Readability Formula
- Based on the number of polysyllabic words
http://web.ucdmc.ucdavis.edu/edu/HealthEd/Guide/Read.htm
• Gunning’s FOG Index
- Based on sentence length and words with three or more syllables
http://www.fpd.finop.umn.edu/groups/ppd/documents/information
/writing_tips.cfm
• Raygor’s Readability Estimate
- Based on sentence length and long words (those with six or more letters)

FRY READABILITY GRAPH
Data from Fry Readability Graph (Graphic scanned from Cheek and Cheek, 1983, p.254.)
READABILITY
All of these readability formulas consider only two
elements in determining the level of a material –
vocabulary and sentence length. There are many
other elements to consider some of which are
prior student experiences, teacher’s introduction
of information, format of materials, student
involvement in learning, awareness of purpose for
reading, organization of information, and interest
in content.
EXAMPLES OF WELL AND POORLY
DEFINED VOCABULARY TERMS
• Constants – numbers
that do not contain
variables.
• Discriminant – If the
discriminant is positive
or zero, the quadratic
equation will have real
number solutions.
• Constant – a number
whose value does not
vary.
• Discriminant – When b²4ac simplifies to 0, … .
Thus there is only one
rational solution,
-b/2a. Whenever the
discriminant is positive,
there will be two real
number solutions.

Vocabulary For Activities
JEOPARDY TEMPLATES
Search engine (www.google.com) to find
“jeopardy in the classroom”
• www.teachnet.com PowerPoint template to
make your own game of jeopardy
• www.netxv.net/esc/technology/InstructionalT
echnology/templates/powerpoint.htm
Example of a jeopardy.ppt file
• Many Others
ORAL QUIZZES
• Like the spelling
tests in elementary
school, students are
read the definitions
and they write the
correct vocabulary
word that
corresponds with
each definition.
• For students to
access outside of
the classroom, you
can make
PowerPoint slides,
to put on your Web
site, that
incorporate the
“sound” of spoken
definitions.
AUDIO FLASHCARD 1
• Definition
• Vocabulary Word
AUDIO FLASHCARD 2
• Definition
• Vocabulary Word
VOCABULARY ACTIVITY TO
FORM GROUPS
• Give each student a card as they come
into the classroom that has either a
vocabulary word or a definition.
• Have the students find the student with
the word or the definition that
corresponds with their card.
• After the students are in pairs, you can
form groups of two or three pairs for a
group activity.
PYTHAGOREAN THEOREM
• The sum of the squares
of the legs of a right
triangle is equal to the
square of the
hypotenuse.
• Let students see this
definition “illustrated”
with a hands on activity
using graph paper.
• Internet activities using
manipulations online
