One teacher - one class - multiple subjects

[mercurialuser]

I have a teacher with 10 hours in a class (1A) and 8 in another (2F)

For example in 1A she teaches writing(4)+history(2)+geo(2)+reading(2)

She needs to have 3 consecutive hours in a class at least once in a week to do writing tests.

I created one activity of 10 hours split 3+1+1+1+1+1+1+1 so that she will arrange the distribution of the Subjects herself and speedies up the loading of the data...

I also set max 5 teaching hours (out of 6) for all Teachers.

How can I specify that she can't teach more than 3 hours in a class each day?

It is highly recommended to split an activity into no more than n days per week (FET instructs you how to do it, if you try to split into more than n days per week).

Then, you can either use min days between activities or activity tag max hours daily (you need to add activity tags in this last case).

Actually the program only alerts during manual loading of the activities, while I imported them.

Sorry I don't understand how I can use "min days between activities". 10 hours, max 3 per day, 5 days, "min days between activities" to 1... doesn't it transform to 3+0+3+0+3, total 9?

I am really new to FET and I may be misinterpreting and perhaps also mis-using the software... I'm now thinking about changing the activity and splitting into 4 different subjects:
writing 3+1
geo 1+1
history 1+1
reading 1+1
but if I do this, I can avoid to have in one day writing3+geo+history+reading?

I think that I may assign the teacher name as the activity tag and use the advanced constraint.... or not :-)

I just checked. Adding an activity split into 6, with a 5 days week. Adding in the GUI. It displays a warning with instructions.

Min 1 days means for instance Monday and Tuesday is OK, plus you can have weights under 100%, which can be broken.

I was talking to add min 1 days 100% between the activity with duration 3 and each of the others, but you need to add many constraints.

Maybe the best is to use activity tag max hours daily.

Hi .. I have a similar problem I guess. My timetable with FET mostly works out OK except for a few minor inconveniences / problems.

This problem is mainly related to situations where one teacher is taking multiple subjects in a class. In such cases, FET (I am using the latest version 5.27.2) still somehow manages to give me a timetable where the same teacher is in the same class for more than 2 or 3 periods (say activities). This is mostly undesirable and to be avoided. Please advise how to solve this ??

Otherwise there is only the manual option to let FET generate the time table, then keep most of the data intact and make the necessary corrections manually in word or excel after importing the HTML file but this is very tiresome and cumbersome and often there are problems that are not resolved so it would be excellent if FET could help to resolve this issue.

thanks

Either modify the weight of min days between activities constraints to 100% or use constraint teacher(s)/students (set) activity tag max hours daily.

I think I don't get it .. sorry to be a pain .. but it works like this .. the teacher can indeed have 2 or say even 3 periods in a day maybe with same or different activities .. but what I want to try and avoid is consecutive periods / activities by the same teacher in the same class .. is there a better constraint for that ??

For eg. we have 8 periods in a day - now the teacher could have say, the 1st, 3rd and any of the periods from 5-8 but not 2nd or 4th as then it would become consecutive periods in the same class for the same teacher - which does not work out too well for either our teachers or the students .. (Even if the subjects to be taught are different .. but sometimes FET puts the same subject consecutively as well ..

I can mail you my data file if that helps !!

FET puts the same subject consecutively if you make the min days between activities constraints with weight less than 100.0%.

I guess you can use constraint teachers/students activity tag max hours continuously. Why can't you?

Yes, you may email us your file. To me and to Volker only, if it is private.

Ok I am trying this .. but not sure about the right place / option .. anyway have mailed you the file too .. Please look at classes IIIA & IIIB and class XI in particular where this is occuring most of the time where a teacher gets consecutive periods ..
