Quote from: Anna ari on February 24, 2024, 06:51:30 PMThanks for the consideration! In our school we firstly schedule the musical instruments' timetable,and general lessons follow. There are many parameters, of which the most difficult is that each class is ordered alphabetically and not by musical instrument, e.g. in A1 there may be four violins, no clarinet and three percussions. The only solution that I have figured so far is to "break" classes with multiple ways, such as second language, musical theory etc, but manually
For the same year, the students groups should be split in such a way that for every elective musical instrument the students are distributed evenly into their respective groups. So, the first criterion should be the elective musical instrument, and the second criterion the alphabetical order of the students.
For example: If the 1st year of the Gymnasium has 15 students whose the elective instrument is guitar and the year should be split into students groups, each group should have 5 of these students. The first 5 students (according to their alphabetical order) should be "placed" in the A1 group, the second ones in A2, and the 3rd ones in A3.
The law is very clear. It provides the school with two alternatives. The 1st alternative is to follow the alphabetical order criterion. Most of the time, the realization of this 1st alternative makes the musical instruments timetable really difficult, or even impossible. The 2nd alternative (according to the law) is to split the students accordingly to their elective instrument (in the above described way). Of course, in order to make the timetable possible, the 2nd alternative is much more flexible.
