Design Guideline 1: Layout of Dynamic Activities
Short explanation
At the beginning of a Dynamic Activity, you should give an explanation of its content. Keep the text short (no more than one or two sentences) and write it in a personal style.
Few Tasks
You will usually add questions or tasks to make sure that your students use the Activity effectively. Place these tasks close to the interactive applet (e.g. directly below it). Don't use more than three or four questions / tasks to avoid scrolling. If you have more tasks, consider breaking your Activity into several pages.
Avoid distractions
Make sure that your Dynamic Activity just contains objects that are relevant for the objectives. Neither use unnecessary background or purely decorative images, nor background music on the web page in order to not distract your students from reaching the objectives.
