Teacher not have two consec. hours with same group

[Yaciel]

Thank you! The first option has solved my problem, now I have another question, can I do for a teacher to not have two consecutive hours with the same group?

I do not want to do:

Hour 1 - Mathematics - Third Grade - Teacher John
Hour 2 - Physics - Third Grade- Teacher John
Hour 3 - Chemistry - Third Grade - Teacher John
Hour 4 - Statistics - Fifth Grade - Teacher John

I want to do:

Hour 1 - Mathematics - Third Grade - Teacher John
Hour 2 - Statistics - Fifth Grade - Teacher John
Hour 3 - Chemistry - Third Grade- Teacher John
Hour 4 - Physics - Third Grade- Teacher John

There is a minor mistake in your post, as also second variant has 2 consecutive hours with same group (Hour 3 and Hour 4).

I think you should use constraint teachers activity tag max hours continuously or students sets activity tag max hours continuously, as you consider easier. For first variant, you must add same activity tag for same students set, for second variant you must add same activity tag for same teacher.

an other variant is to do it "harder" by moving them on different days with a min n day constraint.

but on the other hand you should maybe happy if you have 2 consecutive hours.

most teachers at our school like that, because you can teach more flexible.

example:
i have math in the first hour with class 10a and
i have physics in the second hour with class 10a.

so i like that very much, because:
- if there is a longer physics experiment, then i can do that in the first and the second hour without interrupting the experiment. of course i do a double math hour next week to balance the number of hours.
- if i write a math test, then they need 2 hours for this in year 9 and 10. so i don't need to swap with other teachers activities. i can just write the math test in both hours.
- if my first hour/lesson is not completly finished, i just use 5 or 10 minutes of the second hour to finish the content of the first hour.
- if the content of my first hour/lesson is already finished 5 minutes before end of the hour i don't need to "extend" that lesson. i just end and can start with the next subject.
- ...


it can also save much "swapping time"/"change room time", because students or teachers don't need to change the room because they can stay in the room.
so there is less crowed on the floors.

so we like such consecutive hours very much.
