Accessible Moodle (implementation guide)
The implementation aid Moodle barrier-free serves as support for the Moodle barrier-free checklist. The order of the aspects and the structure according to categories are the same.
Under the heading "What is meant by this? " you will find a detailed description of the aspect to be ticked off. The section "Why is it important?" describes which barriers you are removing with the respective aspect and for which groups of people this is essential. Finally, under the heading "How can I implement/check this?" you will find detailed instructions on how to implement or check the respective aspect.
4. Heading
4.4. Numbering of headings
The headings are numbered exclusively with Arabic numerals ("1"), not with Roman numerals ("I") and do not exceed the decimal structure of level 6 (e.g. "1.1.2.3.4.5")
What is meant by this?
When numbering headings, make sure that they are marked with Arabic numerals (1,2,3...) and not with Roman numerals (I, II, III...), because Roman numerals are often created by using letters. These are also read out like letters to students who use a screen reader. Numbering with Roman numerals is therefore difficult for them to grasp and can lead to confusion. In addition, the use of Arabic numerals represents the international standard for the representation of numbers and is used for the communication and exchange of information in different countries and languages.
The decimal structure of headings, e.g. when subdividing chapters into subchapters, should not exceed level 6 for the sake of clarity. This means that sub-headings and any numbering should not be overstretched, as otherwise there will be a lack of clarity. There is also a restriction in Moodle: the lowest heading level is h6.
Why is it important?
A missing or opaque hierarchy can impair readability and therefore accessibility. In addition, too many subheadings can quickly lead to confusion and make orientation within the document more difficult.
How can I implement/check it?
The number appears before the text of the heading. During and after the creation of the numbered headings, check that the numbering has been carried out using Arabic numerals only.
