A domain is a group of learning objectives. Learning objectives are goals or skills students have to reach or acquire after completing a course or assignment. You can use the analytics of Ans to check whether the students acquired the right level of the learning objectives. You can also use this information to analyse the teaching method.
Domains with learning objectives can be imported with the use of a template. They are connected to either a question bank or a course. You can set multiple domains and each domain can contain multiple learning objectives. Often, the domains are the equivalent as the layers of a taxonomy (e.g. the taxonomy of Bloom).
Now you understand what objectives are, you can start using them.
