Personal Learning Designer

The Personal Learning Designer can be used to set up conditional events. 

As far as I know, the PLD also can be useful for:

• You can have an email sent out to the student if they haven't logged in for a week.

• You can redirect to a certain page the first time they access the course.
• PLD is course by course basis - shouldn't affect other courses
• When they complete a quiz, email them, or something similar to this. - done through the PDL.

This is a snippet of the official documentation on the PLD to give you an idea of what it can do. 

Our Personalized Learning Designer (PLD) is designed to make your life easier. Use it to identify at-risk, inactive, or failing students. Then use the alerts in PLD to implement a remediation process and an appropriate learning path for each student.

How the Personalized Learning Designer works

The PLD uses rules to trigger automated events in your course. You can create rules to reduce excessive manual effort and reach out to at-risk students. For example, a rule can watch for
at-risk grades and send messages to key figures in the student's life. A rule could also
encourage students by watching for the completion of activities.

Each rule has an event, optional conditions, and at least one action.

• Events: An event is what triggers the rule, or causes it to run.
• Conditions: A condition determines if there are actions when an event occurs. If there are no conditions, actions happen automatically.
• Actions: An action is what happens when the right conditions are met.

With the PLD, you can combine different events, conditions, and actions within a rule.
