All the time limitation examples shown so far assume that lessons take place once a week in a given period. However, it could be that certain subjects should be taught not on a weekly basis but e.g. fortnightly.
You can find a description of periodicity in the manual Multi-Week Timetable in chapter ' Periodic lesson group '.
The following example will illustrate why it is advisable to work with factors for lesson groups .
Example:
| • | Please open the Demo2.gpn file and deactivate the class, teacherand subject factors. . |
| • | Activate '*Count only school days' on the 'Value calculation' tab under 'Settings | Miscellaneous'. |
| • | Under “Settings | School Data”, select a weekly periodicity of 2 |
| • | Then define two lesson groups: “WA” for week A and "WB" for week B. |
| • | Assign lesson 50 to lesson group WA and lesson 51 to lesson group WB. |
You can see that the values for the two lesson are not identical. The difference is due to that the lessons in week A can be held for a total of 20 weeks while thos in week B can be held for only 18 weeks.
Entering a factor of 0.500 for both weeks will result in both weeks being counted equally.
