ANGEL HTML Editor
ANGEL HTML Editor ¡Available in multiple tools E-mail, page, quiz (“assessment”), dropbox, syllabus editor ¡Benefits Good editing tools HTML easiest for screen readers, other tool to process
ALT Tag/Text/Attribute Image from Wikipedia ¡Text which replaces image if it can’t be processed ALT=“Washington at Valley Forge in winter snow” Appears when image fails to load
Adding ALT Text ¡ Add “Short Description” or “Alternative Text” when inserting image.
Usefulness of ALT Text Page with images not loaded and missing ALT text Images from BBC
Pick the Best Two ALT Tags ¡Context: 6 Nationalities of Texas 1. Wow, Six flags over Texas! 2. Image taken from Wikipedia. Photo by Ann W. 3. 220 px_Six_flags_over_Texas. jpg 4. Photo shows flags of Spain, US, Mexico, France, Republic of Texas and Confederate flag 5. Photo of six flags read information below 6. Photo shows 6 flags of different colors waving in the breeze on a sunny day. Three are red, white and blue….
Full Image of Six Flags
Complex Images ¡Too complex for an ALT tag Describe in main text and use short ALT text Colonial New Netherland stretched from New York City (New Amsterdam) up Hudson River Valley to north of Ft. Orange (modern Albany) Colonial New Sweden was centered on the Delaware river and stretched from the head of the bay to a little south of Trenton. (Text includes details not in image) Image from Wikipedia
ALT Tag Exercises Twinned Pyrite Crystal (Wikipedia) Athens Greece (Wikipedia)
Unclear Link Text ¡Avoid For more information about accessibility, click here ¡ Or learn more here, here and here “Learn about additional international resources that might be useful in class or in research” ¡Blocker because Screen readers search for/scroll through links “Here” is small (hard to find) and ambiguous ¡Try This You can get more information from Accessibility at Penn State Learn more from “International Music Links” ¡This strategy works across all tools!
Scanning Links on a Screen Reader
Headings on a Page Wikipedia article using subheadings to mark topic changes
Headings on Screenreaders ¡Screenreader users can call up lists of headers and links in their screenreader and jump to that point in the screen
Headings in HTML Editor ¡Access in Format menu
Marking Large Text as Headings ¡HTML Editors Look for Heading 1…Heading 6 menu option =H 1, H 2…H 6 tags ¡Word Heading 1…Heading 6 styles ¡Power. Point Slide titles Bullet levels
Tables: Simple vs Complex ¡Simple Tables Have no merged cells or empty cells Rows represent one type of data Columns represent another type of data Are easier to accessify Are easier for screen readers to process ¡Complex Tables Are popular, but not always user friendly Tricky to maintain Often based on layout from print sources ¡ We have different options on the Web!
Well Marked Data Table ¡CAPTION “Windows ALT Code for Currency Symbols” ¡TH = Table Header 1 st row 1 st column Headers allow screen readers to match cell with row, column
ANGEL Table Tools Allows you to add caption, headers, summary (invisible, but read on screen reader)
TABLE Troubleshooting 1

ANGEL Select Question page
Radio Button: Accessible and Usable ¡Found in Multiple Choice, True/False ¡Highly accessible The radio button is easy to select gives the user the option to select before and after the question. http: //accessibility. psu. edu/angel#quiz
Multiple Select Questions: Accessible and Usable ¡Check boxes are provided that have the same beneficial functions the Radio Button; before and after selection! ¡Specify “Check all that apply”
Combo box Popup: Accessible BUT NOT Usable Combo box popup ¡ The selection boxes do NOT repeat after the question. ¡ Multiple selecting required. One to select the pop up. Second to select a choice. ¡ The alphabetical bulleting is automatically formatted even though the combo box popup is numerical selections for ordering questions. ¡ Choices can be selected more than once.
Matching: Accessible, NOT Usable ¡Requires a tabular list of information above. ¡Long list of choices maybe cognitively challenging on short-term memory.
Ordering; Accessible, NOT Usable Ordering Issues ¡ Combo box popups in ordering questions use numerical selection and is associated with an alphabetical order in ANGEL. ¡ The task is NOT explained in context of the selection tool. ¡ The same number can be selected twice. ¡ Difficult to navigate back to change an answer.
Re-worded Ordering Questions ¡Explain the task ¡Limit the number of items to be ordered. ¡Combo popup boxes still NOT user friendly. Use Multiple Choice version of question. Still difficult to navigate to change answers Multiple selecting process
Multiple Choice Alternate for Ordering Worst version More usable multiple choice
Fill-in-the-Blank: Accessible and can be Usable ¡Potential Gotchas The task maybe unclear. The blank space requires filling-in before the context of the sentence is understood. Navigating back to the blank space is difficult.
The Usable and Accessible Fill-in-the-Blank ¡Provides the user to hear the entire sentence first before inputting the answer. ¡Allows the user to hear the entire paragraph before entering the answer. ¡Using a word bank? Identify them and place them before the paragraph.
How to write a Fill-in-the. Blank/Cloze ¡ Use _1_ to control position first blank Then _2_, _3_. . .
NOT Accessible Games/Flash ¡Games = Crossword Puzzle, Quiz Show
