I am working on PowerPoint slides for a physics class. On the attached pages, would you place the blue text in the graphics as captions in 7-5, preceded by TNCaptionTN? Or perhaps just plain 3-1 paragraphs? Can I ignore the blue pointer lines from the blue text and assume the text is sufficient for the student to know which element of the tactile is referred to?
Also, if a diagram is repeated on a page later in the slides (sometimes on consecutive slides, but sometimes several slides later), is it customary to repeat the tactile graphic or to use a TN to refer the student back to the previous instance?
Thanks in advance,
