But some people start asking the question...
Should we block access to higher education to
someone because they do not master a skill that
does not further their educational goals?

This is not to say that students shouldn’t take math...
But is the algebra needed for Calculus the most
appropriate math for everyone?

You mean all math isn’t algebra?
The new vision for college mathematics
Multiple pathways that are rigorous and meaningful to
students’ programs of study and lives...
 STEM (leads to Calculus or technical programs with
a need for algebraic manipulation)
 Statistics
 Quantitative Literacy (QL) or Quantitative Reasoning
(QR)

What is Quantitative Literacy?
QL prepares students with the skills needed to
be an informed, thoughtful and discerning
citizen and consumer in a world saturated with
quantitative information.

What is Quantitative Literacy?
Despite is occasional use as a euphemism for statistics in
school curricula, quantitative literacy is not the same as
statistics. Neither is it the same as mathematics, nor is it (as
some fear) watered-down mathematics. Quantitative literacy
is more a habit of mind, an approach to problems that
employs and enhances both statistics and mathematics.

What is Quantitative Literacy?
In math, what we need is “quantitative literacy,” the ability to
make quantitative connections whenever life requires (as
when we are confronted with conflicting medical test results
but need to decide whether to undergo a further procedure)
and “mathematical modeling,” the ability to move practically
between everyday problems and mathematical formulations
(as when we decide whether it is better to buy or lease a new
car).

What is Quantitative Literacy?
Quantitative literacy insists on understanding. This
understanding must be flexible enough to enable its owner to
apply quantitative ideas in new contexts as well as in familiar
contexts. Quantitative literacy is not about how much
mathematics a person knows but about how well it can be
used.

Development of Quantitative Literacy. in Quantitative Literacy: Why

What is Quantitative Literacy?
Quantitative literacy is simple math used in
complex situations.

Is this college material?
Do college students have these skills?
2003 National Assessment of Adult Literacy (NAAL)
• Measured quantitative literacy defined as “the knowledge
and skills needed to identify and perform computations
using numbers embedded in printed materials.”
Percentage of people proficient or above:
• Bachelors degree: 31%
• Graduate courses or a graduate degree: 36%
