Material package accessible teaching: Lista: Moodle accessible (checklist)

A reference to internal or external textual or graphic objects is made by explicit naming, not solely by means of a description via visual or auditory features.
The use of colours is generally sparing.
If colours are used to convey information (e.g. in diagrams or to mark text), labels, symbols or patterns also convey the same information.

The selected course format is accessible.
The course is clearly structured and not overloaded.
Sections, text pages and activities are clearly labelled and are not repeated.
Text fields contain a heading that summarises the content of the text field.
A table of contents is created for a long, extensive course.
The activities (e.g. task, feedback, glossary) selected according to content and method are as accessible as possible.
The question types selected in a didactically sensible way according to content and method are as accessible as possible.

The font is sans serif (e.g. Arial, Helvetica) and not too thick or too thin.
The text is left-aligned.
Lists and enumerations are created with list and enumeration formats. Only content that is actually a list/enumeration is output as a list/enumeration.
Texts have a sufficient contrast ratio to the background. For large texts from 18 pt. or bold texts from 14 pt. at least 3:1. For all other texts at least 4.5:1.
Texts are formatted using paragraph formatting ("Paragraph"). Consecutive blank lines are not used to generate text spacing or paragraphs.

Headings are created in the text editor using style sheets.
If there are subheadings, there is every level without skipping a level (h1 - h6). The heading order is consistent.
On a text page, the first heading is labelled h2. If headings other than the default ("Name") are used within the description of an activity or in the material book, these start with h3. In a text field (visible on the course page), the first heading is labelled h4.
The heading is numbered exclusively with Arabic numerals ("1"), not with Roman numerals ("I").

URL does not appear as plain text in the body text. Instead, hyperlinks are inserted, clearly named and easy to understand.
If a link opens another programme (e.g. browser, email programme), this is indicated in the link text. Example: "Contact address" (opens email programme)".
Links open in the same window, not in a separate one.

Graphics contain a short, concise alternative text (max. 125 characters). Graphics with no meaning are labelled as decoration.
Complex images (e.g. diagrams, comics) have a detailed descriptive text alternative.
Graphic information-bearing elements (e.g. lines, neighbouring surfaces) have a minimum contrast of 3:1 to the background.
No images are used to display text (font graphics).
No animated graphics are used.

Uploaded videos can be switched on and off and do not play automatically.
Provided videos with relevant auditory content contain a subtitle.
Videos have an alternative form of presentation: either an audio description or a full text alternative.
Videos and audio files have a meaningful title.
Embedded audio clips have a transcript (as text on the page or in a separate document or on an external website).
Audio recordings (>3 minutes) can be paused or stopped and the volume can be adjusted.

Tables are created with the table settings of the editor. If tables are copied from other documents, their table properties are checked.
The first line of the table is labelled "Header".
Cells are not connected to each other.
Tables have a meaningful title (caption).
Complex tables are divided into several simple tables. Only content that actually represents a table is used for a table (not for purely decorative purposes).

The materials provided in the course are clearly named and the format is indicated (e.g. "PDF").
The materials provided in the course itself are accessible.
