A situation or question that presents perplexity, or a challenge, a mystery or puzzle which begs to be solved. In art education, assignments are often posed as problems. To students of creativity, finding or formulating a problem is considered the first stage in the creative process. George Kneller (American psychologist) called this stage "first insight." A middle stage involves mulling over the problem in a sort of chaos of ideas and knowledge. Jacob Getzel (American psychologist) called this "incubation." The last stage is when the idea is tested as a potential solution to the problem. Getzel called this "verification."Quote: "Look at nature, work independently, and solve your own problems."
