Combined classroom is a specific type of classroom in which teaching is taking place for different classes at the same time. Student share their classroom with one, two or even three other classes. Although combined classrooms existed in the past, more and more students attend these classrooms today. Opinions about combined classrooms are divided so some teachers consider them as „necessary evil“. Still, combined classrooms have a lots of peculiarities, and teaching is different than in normal classes. Except teaching, difference can be seen in teacher's preparation for every class. Teacher's competencies in these classrooms are especially expressed, and it is important that teacher is clever and ready to take every challenge that teaching in combined classrooms brings. Furthermore, it is important to emphasize that every combination of classes is different, so teacher has to adjust to every student in the classroom. Certainly, it is easier to adjust to every student in combined classroom than in normal classes because there are less students in combined classroom. Also, teaching in district schools and smaller cities has its own peculiarities, because teachers and school have a big role in organizing cultural, sports and other events. In all of that organizing there is always help of students and their parents. Older students are more independent so they are big helpers to the teacher, so that teacher can dedicate more time to younger students if needed. Also, younger students follow older student's example. Goal of this thesis is to show specifics of working in combined classrooms and to encourage young teachers for work in such classrooms, because more often they gain their first work experience in combined classrooms.
