Abstract
What are important settings for making learners benefit from animated visuals and illustrations? One interesting method is to use pictures and animations to illustrate phenomena that are not visible with naked eyes. In addition, multimedia can make visualizations interactive and provide possibilities also for combinations with acoustic information. This paper reports about a study with 99 students who worked with a multimedia learning environment. Explained is how infrared motion detectors and infrared thermometers work, and Planck’s law and infrared radiation are made more familiar. Illustrated graphs, animations and thermal imaging were employed. Their information value was assessed. It was distinguished between knowledge that was primarily based on pictorial information or on text based information. The best results provided animations with spoken explanatory text where pictorial imagination is important for understanding. This was significant for all students, but especially fruitful for the not so capable students. Concerning abstract, text based information students with higher abilities profited from written text, while students with lower abilities (median split) gained better results with spoken text.
