Practice, Experimentation & Revision with 2-D Elements and Principles

You’ll be able to

Three engines: practice, experimentation, revision

The investigation row of the rubric names three things a reader must see happening across your 15 images. Practice is repeated, deliberate work that builds skill and control — drawing the same edge until it behaves. Experimentation is trying genuinely different approaches to your inquiry — a new material, palette, composition, or process — to see what it reveals. Revision is returning to an idea or image and changing it on purpose based on what you learned. A strong SI shows all three; a weak one shows only 15 finished, unrelated pieces with none of the visible testing between them.

The 2-D elements and principles are your controls

Experiments need variables, and in 2-D art those variables are the elementsline, shape, color, value, texture, space — and the principles that organize them — unity, balance, contrast, emphasis, rhythm, movement, proportion. To experiment is to hold your inquiry steady and deliberately change one lever: What if I push value contrast to the extreme? What if balance goes from symmetrical to radial? What if I flatten space? Naming the element or principle you are testing turns a vague "try something new" into a real experiment a reader can recognize.

Revision is a decision, not a repair

Beginning students think revision means fixing what looks wrong. In an SI, revision is choosing to change a work because your inquiry demanded it — cropping a composition to force emphasis onto one figure, re-doing a piece in a limited palette to test whether color was carrying too much of the meaning. The most convincing revisions are visible as pairs or sequences: an earlier attempt and its reworking, so a reader can read the decision between them. Document both; the "before" is evidence, not a failure to hide.

Worked example

A student’s inquiry is "How can crowded, repeating shapes create a feeling of anxiety?" Their first three pieces all feel calm and decorative instead of anxious. Design an experiment-and-revision step that uses the elements and principles.

  1. 1.Diagnose which element or principle is fighting the inquiry: the repetition reads as pleasant rhythm, and the balanced, evenly spaced shapes create unity — both calming, the opposite of anxiety.
  2. 2.Choose a lever to change deliberately: break the even rhythm and reduce the comfortable balance, and raise contrast and emphasis so the eye cannot rest.
  3. 3.Run the experiment: remake the composition with shapes crowding toward one corner, wildly uneven spacing, and a jarring value clash — an intentional test, not a redo.
  4. 4.Compare the pair and record the decision: does the reworked piece feel more anxious? What did changing rhythm and balance actually do? That comparison is the revision evidence.
Answer: The student holds the inquiry (anxiety through repeating shapes) fixed and treats the principles as variables: replacing even rhythm and balance with crowding, contrast, and emphasis. Keeping both the calm original and the tense revision documents a real experiment and a reasoned revision — precisely what the investigation rubric row rewards, because a reader can see the decision, not just the result.
On the exam

When you photograph work for the SI, deliberately include evidence of process and revision — studies, alternate versions, in-progress shots — not only polished finals. Some of your 15 images should show the investigation itself. A portfolio of 15 finished, unrelated pieces reads as a gallery, not an inquiry, and loses the investigation row.

Checkpoint

A student wants to "experiment" in their Sustained Investigation. Which action best qualifies as experimentation in the AP sense?

Tip

Keep a running list of the six 2-D elements and seven principles taped near your workspace. When stuck, ask "which one have I not tested against my inquiry yet?" That single prompt generates most experimentation and keeps your 15 works from repeating the same solution.
