Blog 4 - Visual Literacy

What is visual literacy? Why is it important for K-12 eLearning?

Visual literacy is the “learned ability to interpret visual messages accurately and to create such message” (Smaldino, Russell, & Lowther, 2008, p. 136). Like literacy learning (reading and writing of the verbal message), visual literacy is the seeing of the image to aid in learning. There are seven learning styles (http://www.learning-styles-online.com/overview/). A person may be more of an auditory learner, yet even they benefit from visuals to help them understand certain concepts.
There are two approaches in visual literacy – input and output strategies. Helping learners decode, read the visual, is the input strategy. Helping learners write or deliver the visual is the output strategy.

An educator should not assume just because there is a visual component, that the learner will be able to successfully understand the visual. The learner must be guided through the correct decoding of the visual. They must be taught the skill of interpreting visuals. An educator should realize that younger children often interpret the images more literally than older children; these children do not interpret visuals as a whole, but rather section by section. Older students can summarize the whole image and draw a conclusion about the visual’s meaning. Younger children need more realistic visuals compared to older children who can handle more abstract visuals.

An educator should also consider the learner’s cultural background when teaching. A Native American student can interpret scenes of the Old West differently than a Mexican American, African American, or Caucasian.

A colorful photograph might look beautiful and realistic; however, it may not be the best visual for learning. Learners do prefer photos over drawings. If the lesson is about to show the parts of a flower, a photograph, even though it might be close-up of the flower and very beautiful, might not be the best option. It would be better to have a detailed drawing of a flower. By using the visual students develop their visual ability.

Visuals can help students in the learning process; sequencing is an important skill to acquire. Using visuals can help the students put events/objects in a logical order. When learning story structure (beginning, middle, and end), a student can use visual images of the story or phrases of the story events that were placed on file cards and manipulate the cards to place the cards in the correct sequence order.
Visuals are important in the K-12 eLearning as it provides concrete reference for ideas, makes abstract ideas concrete, draws the learner’s attention and thinking to the important parts of the visual (done may color, word, arrows, icons, shading, and animation), reiterates important information that may have been presented verbally or written, allows for recall of prior learning, and can simply the learning of complex topic (e.g., a diagram of the water cycle can help a student understand this complex cycle).

The type of visuals has an impact as well. A visual can be realistic, analogical, organizational, relational, transformational, and interpretive. A photograph, such of a photo of a covered wagon, is more realist than a verbal explanation of a covered wagon. How the visual is designed and laid out play an important role in interpretation of the visual. Referencing the Periodic Table of Visualization (http://www.visual-literacy.org/periodic_table/periodic_table.html) can be very beneficial. This table provides ideas for visuals broken down into data, information, concept, strategy, metaphor, and compound visuals. The visuals can then delivered using as complex delivery as necessary – paper, electronic flat image, 3D object, to an interactive image.

Visuals are very important in the K-12 eLearning environment since visuals can enhance the learning. With today’s emphasizes on assessments, especially state standardized testing, the use of multimedia can impact test scores. Studies by Levie and Lentz have shown that test scores increased by 36 percent; Richard Mayer’s study has shown that test scores increased by 42 percent (Supporting Research). When sights, sounds, and text are combined the learner’s retention level can be up 80 percent (Supporting Research).

With today’s technology visuals are part of our everyday. Students are exposed to television, smart phones, tablets, games, and World Wide Web – all chalk full of visuals. One should remember, however, that a visual does not have to be complex and expensive. A simple stick figure drawing may be able to convey the same message as a photograph. Drawings on paper, poster boards, or chalk boards are relatively inexpensive compared to drawing the image using a computer program or an interactive whiteboard.
