  • For decades, scholars and researchers have explored the effects of instructional graphics on learning. In doing so, instructional graphics have been described, labeled, and classified in multiple ways based on their content, composition, medium, mode, and function.
  • (Sweller, van Merrienboer, & Paas, 1998)
  • Representational graphics physically depict someone or something and “share a physical resemblance with the object they are supposed to represent” (Rieber, 1994, p. 36). Representational graphics depict a particular subject and can be used to visually describe someone or something.
  • Learning often takes a learner down the path of what is known (prior knowledge) toward new knowledge (Reigeluth & Curtis, 1987; Rieber, 1994). Analogical graphics can be used to activate prior knowledge and bridge the learning gap from the known to the unknown. Therefore, “The usefulness of [analogical graphics] . . . is largely dependent on the learner's prior knowledge (Rieber, 1994, p. 39).

  • Organizational graphics provide an efficient and orderly approach to displaying complex and often abstract information.
