Yes, this remains the same as older version of Moodle.  You can share a module with another lecturer or have a separate area in Moodle.

There are a number of options available if you want to share a module with a colleague(s).
   
1.  All work in the same module area
Several may be sharing the one module including lecture notes and resources.  In this situation, it may be suitable to all work in the same module area in Moodle.  All lecturers must first be added to the module as lecturers in Moodle.  This can be set up by sending an email to moodle@wit.ie requesting to be added as a lecturer to a module(please state the CRN number of the module).  Alternatively consider option 2.
   
2. Sub-divide the module into a number of newer modules
If there are several lecturers delivering one module and each desires their own module space in Moodle that only their group of students can access, then it is advisable to sub-divide the module into a number of different modules.  Simply send an email to moodle@wit.ie to request a module be broken into a number of different modules and the lecturers added to the new module areas.

However, there is one drawback, we in the Moodle office have no way of knowing which lecturer is teaching which group of students as this information is not stored in any central information system.  Therefore, a lecturer needs to manage their own enrollments on sub-divided modules.

UPDATE September 2022 - we are no longer facilitating Module Splits
