Introduction
to the Online Compare/Contrast Tutorials
Help
Lee Decide and
What
Should Maria Do? are online tutorials for adolescent
learners, particularly those who are having difficulty in reading
and writing in the content areas. The purpose of the tutorials (called
"activities" for the students) is to help students develop
skills in comparing and contrasting. A good place to start would
be the Help
Lee Decide tutorial.
After that, try out What Should Maria
Do?.

Purpose
of the Tutorials
In
these tutorials, students will learn:
- How
people compare and contrast to make judgements, decisions, and
choices
- How
using a grid (graphic table) can assist in organizing and evaluating
information that is being compared and contrasted
- How
using signal words can help determine what elements (attributes)
are being compared
Background
Information
People
make comparisons all the time. However, students need to learn how
to detect and evaluate similarities and differences that are embedded
in text. This is especially true as the items being compared/contrasted
become more complex. Students need to learn how to decide which
attributes of two items should be compared and which similarities
and differences are important. They also need to learn how to write
texts that compare and contrast ideas.
Compare
and contrast is one type of text structure. (For more information
on text structures, visit our section about text
structures). We have chosen to use the term compare/contrast
to align with terminology used in schools and curriculum standards.
Compare usually refers to finding similarities, while contrast refers
to finding differences. However, in common usage when people refer
to "comparing" things, they typically imply the need to
identify both similarities and differences.
Texts
that compare and contrast can be written in two general ways: whole-to-whole
and part-to-part. In a whole-to-whole comparison, each item is described
fully in a different paragraph. In a part-to-part comparison, the
attributes of each item are compared within the same sentence.
For
example, a whole-to-whole comparison of a herring gull and mallard
might read:
The
herring gull is a bird among which both sexes look alike, but
juveniles and adults look different. The adult herring gull is
a white bird with dark gray back and wings. It has pinkish webbed
feet. Its yellow bill is slightly hooked, and there is often a
red spot on the lower bill. The herring gull is usually found
near salt or fresh water.
The
mallard is a bird among which males and females have very different
coloring. The male is quite colorful, with an iridescent green-blue
head, a white ring around the neck, a ruddy brown breast, and
a light gray body. It has orange webbed feet. The tan bill has
a dark spot on its flattened tip. The mallard is usually found
near fresh water.
A part-to-part
comparison of a herring gull and mallard might read:
The
herring gull is a bird in which both sexes look alike, while male
and female mallards differ greatly in coloring. On the other hand,
juvenile and adult herring gulls differ in coloring, while mallards
do not change appearance as adults. The adult herring gull is
mostly white with a dark gray back and wings. By contrast, the
male mallard is quite colorful, with an iridescent green-blue
head, a white ring around the neck, a ruddy brown breast, and
a light gray body. Both gulls and mallards have webbed feet, but
the herring gull's feet are pink, while the mallard's are orange.
[and so on
]
Whole-to-whole
comparisons may be somewhat easier to process, but the reader often
has to infer the similarities and differences between each item.
Part-to-part comparisons may assist the reader in identifying similarities
and differences between items, but the writing may seem choppier.
The writing that students encounter in actual textbooks and other
sources may mix these two styles.

Directions
The
tutorials present different students talking about their plans for
the summer. In the first tutorial, Lee is trying to decide what
job to choose by comparing the plans of his friends. In the second,
Maria has to decide between going to the Grand Canyon or the beach
for her summer trip. The students plan to compare/contrast to make
their decisions. They apply the relevant strategies for comparing
and contrasting. Your student(s) will follow the steps the characters
take. They will actually participate in the process.
The
tutorials are self-directing and self-paced. Essentially all that
students need to do is launch a tutorial (called an "activity"
for the students) and follow the cues. Depending on the level of
your students, they can work alone or in pairs. You may want to
select only certain students to engage in a tutorial, or all the
students could complete it in a computer lab or as homework. It
is important for you to go through the tutorials yourself to determine
how to use them most effectively with your students.
The
tutorial are introduced by one or more context-setting activity(s)
and followed by additional follow-up activities. We have provided
activities that are related to text structure generally and also
specifically to understanding comparisons in reading and writing.
Feel free to use any or all of them, depending on your student(s).

After
your students try out Help
Lee Decide
and What Should Maria Do?,
you may want to send them to these two sites for other tutorials
on compare and contrast.
Comparing
and Contrasting
Prentice Hall uses a science example to teach compare and contrast.
There is a simple exercise for students to do online that involves
comparing and contrasting two different kinds of cells.

Compare
& Contrast
This site provides practice quizzes for students in grade 3 and
other students who need reinforcement.
