Learning Standards
NCTM:


Connections: “Recognize and apply
mathematics in contexts outside of
mathematics”
Data Analysis and Probability: All expectations
Illinois Learning Standards:


Applications: Communicating and making
connections
Goals 10A & B: “Collect, organize and analyze
data using statistical methods [and] predict
results…”
Curriculum Context
Statistics is one of four full-year elective
courses beyond Algebra 2/Trig; students
must take at least one. Other courses
include Pre-Calculus and two years of
Calculus. Some students take Statistics to
avoid more rigorous mathematics; some
take Statistics concurrently with another
math course.
The course covers all the material tested on
the Statistics Advanced Placement exam;
some students take the AP each year.
Statistics Course “Syllabus”
Major blocks of study:



Descriptive Statistics
Fundamentals of Probability
Design of Experiments

keyed to each
major block.
Social Justice
Definition?
Scope?
Do students understand the concept?


Students have a schoolyard concept of fairness,
and are (at least superficially) aware of some
issues related to social justice.
At the outset, students have been unable to
articulate even an informal definition of social
justice.
Student Involvement
Day 1: Introduction to course included a
definition of Statistics as a tool for making
sense of the world; students were told that
the year would include a “focus on social
justice.” We discussed (briefly) what that
might mean.
Week 1: As part of the first problem set,
students were to research the meaning of
the term “social justice” and write down
their own working definition (with
references cited)
Further Student Involvement
General discussions
Use of data sets in student assignments
Use of data sets related to social justice
issues in class lecture/discussion
Guest speaker “colloquia” from community
or other groups
Social Justice Discussions
Classroom discussions: genocide, Hurricane
Katrina, Kashmiri earthquake, NCLB,
affirmative action/college admissions, others
according to student interest
Method: Introduce topic at the end of a
lesson (last 10 minutes of class), continue
discussion for 10-15 minutes the next day.
General class discussions about once every
two weeks (sometimes more often,
especially during the aftermath to Katrina)
Discussion Ground Rules
How does the definition of “social justice”
fit?
Is there a way to measure fairness?
What kind of data would you like to be able
to collect?
What variables and/or factors contribute to
the situation? How are they related—cause
and effect?—explanatory?—response?
Are there different “sides” to the issue?
Lab Activities
Statistics skills involve data; why not
choose relevant data for the students to
work with?





Graphical representations
Transformations of data
Correlation and regression
Confidence intervals
Hypothesis tests
In the lab write-up, students address social
justice and mathematical issues.
Data Interpretation Exercise
Match the group with
the graph… data
shows mortgage
refusal rates for 20
large banks.

Where’s the fairness?

Classroom Activities
Modeling situations:





Identifying variables
Formulating hypotheses
Designing experiments/surveys
Interpreting data and representations of data
Role play
All of these can be done in a social justice
context!
A Sample Activity: Confidence Intervals
Groups of 3-4 students are given different
settings; they work together to identify
confidence intervals and decide on an
appropriate confidence level in order to
make a recommendation. They are told to
prepare statistical arguments for both sides
of the issue. After working together for
some time, groups present their findings to
the class; the class discusses social justice
implications.
Confidence, Statistics, and Social Justice
 Each group has several scenarios. In each
scenario, answer the mathematical part using
techniques we have discussed in the past week
and a half. Answer the “social justice” part by
reasoning out, considering different viewpoints (at
least TWO different viewpoints per scenario),
adopting a viewpoint if one is not suggested, and
answering the question. Be prepared to either
DEFEND your answer, or to CRITIQUE answers of
other groups.
 After a while, I will assign one scenario
presentation to each group; for now, consider
EACH scenario.
Problem-Based Learning
The idea behind PBL is to give students a realistic,
large, ill-posed problem, from which they extract
meaningful questions, do appropriate research,
then present solutions (IMSA’s web site has a
great description).
Social justice issues can provide an ideal PBL
setting for Statistics projects, whether on a grand
or limited scale.
Example: the Illinois legislature requires the study
of genocide in the curriculum (Public Act 94-0478).
Where? Why not in Statistics?
Student Work: Projects
1st Semester:


Interview with scientist/social scientist about
experimental design
Statistical synopsis of local social service agency
2nd Semester:

Design, conduct, and analyze an experiment (or
analyze a large data set collected externally)
What I Could Have Done (and did, after the
AP exam, instead of a unit on ANOVA):

Social justice project (abbreviated)
Projects with Social Justice Flavor
(by student choice)
NCLB survey of elementary teachers in local
district… (fall 2004)
Career interview with sociologist (fall 2004)
Statistical overviews of work done by Habitat for
Humanity, Planned Parenthood, El Centro, and a
homeless shelter (fall 2004, fall 2005)
Analysis of bullying survey data collected by the
counseling office (spring 2005)
Minority enlistment in the military (fall 2005)
Sex education in public schools (spring 2005)
Social Justice Project
Brainstormed social justice issues as a class
Individuals took an issue and formulated
questions with a statistical basis
Students put together an annotated
bibliography relevant to their issue
Students chose one question to study; they
collected information and used it to “tell a
story.” In addition, they documented their
research process and thinking as part of the
project.
Project Results
Affirmative Action
Birth Control: Pharmacist’s Choice?
Access to abortion
Illegal immigration
Health care costs in the U.S.
Minimum wage
Public funding for sports arenas
Socio-economics of military recruiting
More Brainstorming
Immigration reform

Kyoto Protocol and global warming
Iran and North Korea as nuclear powers
Oil Prices: Where does the money go?
Medicare Prescription Drug Plans
CEO Salaries (or pro athlete, coaches,
celebrities, etc.)
Philanthropy: Gates Foundation & others
What’s Next?
Continuing this year… More guest speakers?
New data sets? New questions?
Students reported that the social justice focus
in 2005-2006 made the Statistics class much
more relevant.


Is a thematic focus (whether social justice or other
topic) appropriate for any math course?
Is an open-ended problem solving approach (PBL
or other) appropriate for any math course?
I welcome any suggestions or feedback (my
contact info is on the handout).
Thanks for stopping in… Enjoy the conference!
