relocation to Oklahoma. A microscopic virus that can inhabit living creatures.
The pattern of solutions for the equation 2x=3y. The geographic locations
of the major volcanic eruptions of the 20th century. The growth in population
of Wisconsin from 1950 to 2000 as reflected by the U.S. Census. The relationship
between increasing levels of phosphates and the population density of
game fish in our streams.
Perhaps you were able to generate some images of the
information described in the preceding paragraph. Clearly, the mental
pictures you evoked were undoubtedly quite varied, ranging from visual
scenes such as those represented by photographs to graphs, maps, charts,
or tables. As proficient readers, we expect that some information can
be better communicated through visuals rather than words. Increasingly,
readers of today's text materials are expected to "read" nonverbal as
well as verbal forms of information.
A quick flip through a new textbook reveals that publishers
are now emphasizing visual displays as a major source of important content.
Teachers sometimes comment that new texts feel almost "cluttered," with
very few pages devoted solely to words. To accommodate the space demands
of visuals, publishers may adopt an "either/or" policy: information will
be either presented in words or in visuals, but not in both forms. Therefore
visuals may assume a primary rather than auxiliary role in communicating
critical concepts.
The Strategy
Many students have developed the habit of skipping visuals as they read
text assignments. In addition, the information derived from some types
of visual displays, such as graphic representations, may not be readily
apparent to students. Ogle (2000) advocates modeling visual literacy strategies
to students as a regular part of the classroom routine.
Step 1: To heighten student awareness of visual
information, engage them in activities that develop the habit of interpreting
nonverbals as a regular practice when learning from texts. One strategy
is to take students on a "visual tour" of a chapter. Create a study guide
that walks them through visual displays and encourages them to spend some
time considering the information presented in each.
Include extensive prompts that guide students toward
interpreting each type of visual. Although the captions provided by textbook
editors may be helpful, often students will need more direction as to
how to "read" the visual. For example, you may wish to ask students to
describe what they are seeing in a photograph or drawing. Graphic information,
such as tables or diagrams, may be best processed through questions that
ask students to notice elements of the graphic and to determine what relationships
might be suggested.
An important aspect of this step is to immerse students
sufficiently into a visual so that they become comfortable encountering
information in a multitude of formats. As students become familiar with
reading various visuals, they can be asked to collaborate with a partner
to create their own tour of a chapter as an assignment. This activity
can be especially useful with visuals that are prevalent within a content
area - math visuals, for example, are quite different from what students
find in social studies texts.
Step 2: A second phase in developing visual literacy
is to involve students in creating their own visual representations of
text information. Ask students to assume the role of "Visual Editor" of
a textbook. Supply them with pads of sticky notes and direct their attention
to a paragraph or two that might be difficult to understand. After reading,
have each student confer with a partner to brainstorm possible visual
displays that might enhance comprehension of this passage. For example,
the following world history excerpt could prove challenging to students:
"Feudalism became the prevalent system in Europe. In
this system, nobles swore an oath of loyalty to the king and provided
him with military support. Each noble, or lord, might have additional
lords also pledged to him, making them his vassals. Thus, underneath the
king were various layers of lords, and a noble might be both a lord and
vassal to other lords. The next level were the knights, or mounted soldiers.
At the bottom of this pyramid of relationships were the peasants, or serfs."
What visuals could be created to make this text clearer?
Each set of partners decides upon a visual, which is then posted on a
sticky note on the chalkboard. Students can then examine their classmates'
ideas and select the visual that works the best for them. In the example
above, students might decide upon a pyramid diagram that clearly indicates
the hierarchy of relationships described in the passage. Each student
"editor" then draws this visual on a second note and affixes it to the
textbook page.
Step 3: Encourage students to experiment with
drawing as a strategy for learning. For example, in a highly visual subject
like biology, students often discover that reproducing visuals that they
are studying from the textbook, labs, and class presentations can be a
powerful means for examining and understanding this visual information.
Use of color in such visuals is especially advantageous. Students begin
to realize that drawing a visual causes them to analyze it in much greater
depth.
Other variations include the Sketch to Stretch strategy
(Short, Harste, and Burke, 1996). After students have read a passage,
ask them to render the most important idea in a drawing. What do they
feel is the central concept of this poem, short story, history passage,
or science segment? Obviously, the intent of this strategy is not to produce
"works of art," but is to ask students to visualize what the words are
saying, and to read carefully for clues as to what to draw. Some students
may be capable of exceptional drawings, but most will probably create
basic sketches that reflect what they perceive in a passage.
Advantages
Students gain practice in formulating mental images as they read, which
is a necessary component for reading comprehension and is often a weakness
for struggling readers. Students began to investigate the balance between
presenting information through writing and representing information through
visuals in their own communications.
