I don't understand your question.
sorry i didnt explain the question well .
okay , first i want to implement moodle in k-12 school , i want to separate students into classes in each stage , so i want 1 course for each subject for the same stage but with multiple teachers for each class , and different activities for each class . also i want to keep recording the grades at least for the previous academic years for the students in the same course , is it possible !! . i hope that its clear now
As you rightly found out, the course is the basic unit of Moodle. One tends to underestimate, may be because the term is so familiar, but creating a good course is a subject of its own. How about conducting a course, assisted by Moodle, for a semester and then expand to design a whole college?
P. S. You may want to ask the moderator to move this discussion to the Teaching with Moodle https://moodle.org/mod/forum/view.php?id=41 forum.
I have moved the thread into the Teaching with Moodle forum. First I'd suggest looking at Moodle site - basic structure. How you organise your students and teachers varies from school to school. In my old school for example we used categories for subjects (eg English, Mathematics) and then had a course per year group - Y7, Y8 ( I am in the UK) and then used Groups to separate the classes in the courses. Students and teachers were added to their groups by a csv file at the start of the year so it was easily managed. So all the Y7 English teachers and classes were working in the same course but if they really wanted to , they could use Restrict access features to only show work to their own classes and hide it from other classes.
However ...this is just one way of doing it and hopefully you will learn some other ways of organising your K-12 school Moodle and you will be able to make your own decision. Also take a look at our Admin quick guide and our Teacher quick guide
