Why Learning Styles Are Out and Dual Coding Is In
We want to employ the best, most effective teaching strategies available to ensure that our students learn and remember. However, it is not always correct that the learning experiences students prefer, or with which students feel most comfortable, lead to the best learning outcomes. We often need to look past what may seem familiar or has been a long-standing tradition to determine the instructional approach that will be most likely to lead to higher levels of learning and lengthen recall.
Consider the practice of teaching to students’ preferred learning styles. For decades it was assumed that teaching students in the mode they preferred—typically visual, auditory, or kinesthetic—would lead to better learning outcomes. Yet, extensive research has shown that teaching to a single, preferred learning mode does not necessarily improve learning.
Interestingly, the challenge with learning-style-based teaching is not the mode of instruction. Rather, it resides in using a single mode for instruction or depending on a single input strategy for learning. When learning modes are combined, the impact on learning grows significantly.
The approach known as dual coding combines two learning modes—auditory and visual—to enhance learning. The concept is to combine multiple representations of content. While research on learning-style-driven instruction has not shown positive outcomes, studies on the impact of dual coding have shown significant increases in learning and improved recall.
Dual coding works by combining two main channels on which the brain depends for processing information. As a result, students hear or read explanations and see images, graphic representations, icons, and other supports to visualize content, processes, and other learning-related information.
Dual coding does not have to be a complicated, cumbersome, or time-consuming strategy. Consider these examples:
- Provide students with graphic organizers to complete as the lesson unfolds.
- Pair meaningful, related images with key written paragraphs and passages.
- Use icons and symbols to reinforce vocabulary words.
- Provide an infographic to accompany new content or an unfamiliar concept.
- Have students draw what they are learning as they hear or read information.
- Coach students to combine words and visuals as they take notes.
- Support the introduction and discussion of historical events with timelines, pictures, and other visual connections.
- Present students with an image and have them write an explanation or interpretation.
- Following verbal and visual presentation of information, have students explain what they are learning in their own words.
While dual coding can be an effective instructional strategy, there are cautions and considerations to observe:
- Be sure that verbal and visual information support the same concept. Misalignment of information between learning modes can lead to confusion and faulty recall.
- Resist overloading students with simultaneous content. Sequence and spread complex information out over time to avoid overloading short-term memory.
- Avoid overdecorating visual information. Excessive color and complexity can work against focus, understanding, and recall.
- Strive to present information clearly. Artistic skills are not a necessary component of dual coding for us or our students.
- Avoid employing too many visuals. One visual at a time typically is best to avoid distraction and confusion.
We know that students often have preferences in how information is presented to them. The advantage of dual coding is that two of the most common learning preferences are featured. We can further enhance learning experiences by integrating body movement and interactive tasks and by tapping social-emotional features such as relevance, empathy, and other connecting elements.
