We are inundated with information: about our
health, about our leisure activities, about sports and so much
more. Information is just information.
It is our responsibility to process that information and to use
it wisely. That is one of the reasons we study data analysis. We
need
to not only evaluate this information, but also to base personal
decisions on evidence (data). We also need to see the dangers of
acting on decisions that are not supported by the evidence. The
question then becomes, “How do we get that evidence?” Of
course the answer is by analyzing the data that we are using to
make those
decisions.
QuizBus: Dealing with Data will help students in Grades
4-8 have practice with collecting data, presenting it in an understandable
fashion, analyzing the data through graphing, identifying ways
data can be distorted and looking at both arithmetic and geometric
probability
(area models). This multimedia package contains five videos, a
teacher guide and a Web site, http://WesternReservePublicMedia.org/quizbus.

The Treatment
QuizBus: Dealing with Data is patterned loosely after the TV program “Cash
Cab.” The actual quiz show takes place in a school bus. At
the start of the program, the bus arrives at a school and agents
exit it in search of “contestants” — four math
teachers. The contestants are led from the classroom to the QuizBus,
which has an on-camera quiz master and an announcer/sidekick, the
bus driver. The game begins on the bus, where the quiz show host
asks a preliminary question or poses a problem that each of the
four contestants tries to answer.
Round 1: In this round, the two
teams who answer correctly move on to Round 2.
Round 2: The two
remaining teams compete in a head-to-head question-and-answer
match. One of these two teams will be eliminated, leaving a final
contestant to answer in the program champion round.
Champion
Round: The remaining team correctly answers a championship question.

What the population and sample are, and
how to find them

What changes could
be made if they did this project again

How to present their data
Video 5
Probability lessons are covered using the following:
The Teacher Guide
The teacher guide is divided into four sections:
-
Teacher pages give complete instructions on how to conduct the lessons. Each
lesson is keyed to Ohio standards in mathematics.
-
Student handouts offer easy access to materials that can help the students complete
the projects.
-
Resource pages can be used by either teachers or
students to get more information on a topic.
-
Data standards are
listed for each grade level and include the corresponding lessons
that meet each indicator.
The Basic Tenets of Teaching Data Analysis
The lessons in the teacher
guide are built around the basic concepts listed below.
-
Recognize
the need to base personal decisions on evidence (data).
-
See dangers of acting on decisions
that are not supported by the evidence.
-
Understand
that tables of data can be viewed in a more simple
or readable format through the use of a graph.
-
Become aware of the fact that
graphs can be misleading if data is not accurately portrayed.
-
Know
that there is more than one way to solve a problem.
-
It is important
to use real (and relevant) data.
-
Emphasis should be on good examples
which lead to intuition.
-
Project work is important. Students need
to recognize the difficulty in asking the “right question.”
-
Variability is ubiquitous (ever present).
-
Always use appropriate vocabulary.
-
Technology can be used, where
appropriate.
The QuizBus Web Site
The QuizBus Web site, http://WesternReservePublicMedia.org/quizbus, offers the
project videos in a streaming format. The videos can also be
downloaded.
The complete teacher guide is onthis site, as well as other
games and activities that are not included in the teacher guide. |
