If you take photographs of people, places, and other examples using a digital camera, they can be quickly embedded in a PowerPoint presentation or uploaded to a website without the extra step of scanning. Demonstrations and examples. Visual images help immensely with demonstrations and examples because they make it possible to show your audience what you are talking about, even if you can't show your students the actual object or event. If you want to show your students the process of cell division and don't have access to a video, you could show students a series of photographs or illustrations of different steps in the process. Grades can make more sense if students can see their work compares with their own previous work or the rest of the class.
Line graphs are effective for showing progress.
A histogram or a pie chart may be helpful to anonymously show the distribution of grades in the class so students can see for themselves where they stand. Including digital photographs of yourself and your students on a class web page can help online students feel like they are more connected to the other people in the class. Material selection and evaluation. Consider the presentation of the content as well as the content itself when selecting your course materials. Content that is technically sound but confusing or uninteresting to the learner may actually impede the learning process.
