Depth & Complexity Icons

The Depth and Complexity Icons are visual prompts designed to help students go beyond surface level understanding of a concept and enhance their ability to think critically. These critical thinking tools help students dig deeper into a concept (depth) and understand that concept with greater complexity.

Carlton staff has incorporated D&C Icons into many lessons to support student learning and encourage critical thinking skills.

The main Icons are listed below:

Language of the Discipline- The meaning of this icon is pretty self-explanatory. The lips represent specialized language related to a topic or concept. This language includes key words, phrases, signs/symbols, figures of speech, abbreviations, and the like.
For example, to truly understand a concept in mathematics, one must speak the “language of math”. A student being asked to add and subtract would need to understand not only terms such as “sum” and “difference”, but also be able to understand mathematical sentences which often include symbols: 27 + (16 - 5) =

In the study of the American Revolution, students would need to know the meaning of “Redcoat” and realize that it isn’t something one can purchase in a store!

Details – As you consider the design of this icon, think about the details of the flower and how each part (flower petals, etc.) make up the whole flower.
Details contain the information that enhance understanding. They act as supporting information to a big idea or concept (main idea). Details include: parts, factors, attributes, traits, and variables. If we go back to our earlier math example: 27 + (16 - 5) = the details are the numbers themselves (the parts that make up the equation).

Being able to discern important details of a story is key to one’s ability to critically analyze that text. While we can concede that one of the pigs in the story, The Three Pigs is wearing a red shirt, we can agree that the color of the shirt is extraneous and doesn’t lead to a deeper understanding of the story.

Patterns – There’s no surprise that this icon represents patterns (note the circle, line, circle, and zig-zag pattern). If one were asked, it would be a fairly simple task to continue the pattern. Patterns are recurring elements or factors in ideas, objects, stories, and events. They are predictable, repetitive and ordered.
We see patterns in math: number lines, geometry; literature: “Little pigs, little pigs! Let me come in…” ; social studies: patterns in movement and settlement, behavior. The list goes on… Being able to move beyond simple identification of patterns to defining the cause and effect of a pattern or identifying relationships among patterns is rigorous and requires the ability to think critically.

Rules- Rules are the organizational elements that create structure. This concept is an easy one for students, as they are surrounded by rules (at home, school, in sports, etc). Rules provide structure and represent organization and hierarchy.
The meaning is reflected in the design of the icon, which itself has a clear structure. This icon is often seen in science when looking at classifications. Students may encounter it when examining the structure of a text (compare and contrast, main idea and details, and the like). They may also be asked to apply mathematical rules (formulas) to solve a problem or utilize spelling and grammar rules in writing.

Big Idea – The Big Idea indicates a generalization, principle or theory about the curriculum being studied. It often represents the focus of study or a learning task. For example, the big idea of a science lesson might be the water cycle.
The Big Idea design works well to help students organize the main idea of a story or paragraph (in the roof), which is then supported with evidence (pillars supporting the roof). Students use this with universal themes and generalizations.

Ethics – This element of Depth and Complexity represents moral principles (possible rights or wrongs). An easy way to remember the meaning: “Black and white/ right and wrong”. It represents conflicting points of view on events, ideas or issues and involves bias, values, or judgments.
Students will most likely encounter this dimension when analyzing literature or studying social studies. For example, students might be asked to consider ethical issues surrounding Spanish colonization and the establishment of missions along the California coast or to examine ethical issues surrounding a character’s behavior in a story.
