In the education system of the Republic of Croatia, a certain number of students begin their primary education in combined classrooms. Those classrooms are specific in that they consist of students from two or more grade levels. Combined classrooms are formed due to a small number of students in particular locations. Planning and preparing lessons in a combined classroom are very challenging and demanding processes. Combined class teaching has its advantages and disadvantages. Advantages manifest in the fostering of friendships and cooperation, and in various ways, students are prepared for learning and independent work. Therefore, creating an atmosphere within the classroom that significantly influences the success and complexity of teaching is extremely important. Combined classrooms are often considered a poor approach to teaching with a reduced number of students, but at the same time, all the positive aspects that teacher and students gain from such experiences are not considered. Since schools with such teaching departments are often located in smaller communities, teachers find it much easier to organize extracurricular activities and thus contribute to all positive aspects of the educational process. Combined teaching can be easily and positively applied to the teaching of visual and musical arts because these artistic areas do not always require a clear boundary between age groups of students, thus facilitating the application of teaching material to two or more grades. The analysis conducted in this thesis clearly identifies advantages and disadvantages of teaching music and art education in combined classes. Fundamental disparities in instructional approach and implementation between homogeneous and integrated classrooms were considered, as well as specific content that proved to be suitable or challenging for implementation in combined classes. It has been shown that, despite the challenges, with careful planning of teaching activities, creativity, and dedication, teachers can achieve exceptional outcomes and deliver high – quality education to their students.
