“Depth of processing considers the richness and depth of exposure to material to support how someone retains information in long-term memory.” That’s how I summarized depth of processing to myself after reading the principle and doing my research.
From the Universal Principles of Design, an example of an online blog article and how deep processing may or may not be supported based upon. Blogs that use text, headings, images, video and survey questions engage the user from a processing perspective in a greater way than does a blog using only text or text with imagery.
Two principles also seen are elaboration rehearsal and maintenance rehearsal. Elaboration rehearsal supports deep learning while maintenance rehearsal may be something you use to simply memorize information; possibly for a test. With elaboration rehearsal, there are three aspects that support deeper learning;
Distinctiveness – the uniqueness of the information, including how it is presented in its context and the experience level of the user.
Relevance – the degree to which information is considered to be important and if it is presented in a way that the user can make the relevant semantic connections.
Elaboration – how much thought and engagement is required to connect with the material and interpret and understand the information. How deeply can the user engage and is the material supporting deep processing.
Considerations for Design:
- Identify targets for recall and retention
- Use unique presentation and interesting activities to support deeper processing
- Use rich media where it makes sense; video, audio, sound
- Give users a choice to create engagement
- Make information relevant to the audience
- Use case studies, infographics, display information visually appropriately, use relevant imagery and data to create deeper learning opportunities.
An example would be the learning layout used by codecademy.com where the user rehearses how to write code from first instruction, but then by gradually thinking more and more on their own, eventually learning to write and build code from requirements. This is an example of elaboration rehearsal as the user is user deep processing to learn a concept into long-term memory.
Here we can see the three panes that make up the user interface and provides the user with learning through elaboration rehearsal and feedback. In the left-hand pane the user is provided with details about how this type of code works, but not the answer to this specific example. The user, building on the knowledge of a previous lesson and the details and example provided, creates or completes the code example in the middle pane, and when the correct response has been coded, the user will see the results if the right-hand pane. Codecademy.com provides the user with the ability to practice, building on the success of each lesson, getting feedback and tips and hints along the way.
A real world example of depth of processing is a map. With the depth of processing principle, seeing how it is supported should provide the user with multiple methods of processing. A map typically provides multiple modes of detail with the use of color, contrast, iconic representation and much more detail as we are learning as part of project 2 mapping.
Here we see the level of detail that is provided supports the users depth of processing. Information is provided though text, images and deeper information that is mapped to the other side of the map, providing the user with context.
The legend is used to drive meaning to the graphical elements used within the visual aspects of the map.
The final image shows where this map is providing detail for, providing deeper context for this map and the user.
