Creating Visually-Appealing Content
Imagination is more important than knowledge - Albert Einstein
This is a beautiful quote that summarizes the importance of visualization in digital content. There are innumerable theories on the use of media in education, some favoring it and some criticizing its extensive use. Media plays an important role in education. Going by Dale's Cone of Experience, various approaches should be used in learning depending on the needs of the learner. The Cone shows the progression of experiences from the most concrete (at the bottom of the cone) to the most abstract (at the top of the cone). The cone was later modified by Raymond S. Pastore to indicate that learners retain 50% of what they see and hear, which leads to the use of media such as images, audio and videos to supplement text. However, how much media should be used to supplement text is debatable.

Creating visually-appealing content depends on your storyboarding and composition skills. The extensive brainstorming that goes between the subject matter experts and the media team decides the characters, camera angles, the background, the voice-over and their relative composition in each screen. This pre-production exercise for each topic decides the visual appeal for the topic.
