The use of calculators in classrooms can be beneficial in certain situations, such as for complex calculations or to save time on basic arithmetic. However, it is important for students to also develop their mental math skills and understanding of mathematical concepts without relying solely on calculators. Therefore, while calculators can be a useful tool, they should not be a permanent fixture in all classrooms as they may hinder students' ability to think critically and problem solve independently. **

Assigning classrooms to classes rather than teachers can have its benefits. It can help ensure that each class has a suitable learning environment and necessary resources. However, it may also limit the flexibility of teachers to personalize their teaching methods based on the needs of their students. Ultimately, a balance between assigning classrooms to classes and allowing teachers some flexibility may be the most effective approach to ensure optimal learning outcomes. **

It depends on the specific circumstances and needs of the students and teachers. If there are students who need a quiet and safe place to study or access to resources during the break, then keeping the classrooms open could be beneficial. However, if the break is meant to provide a complete rest and break from school activities, then it may be better to keep the classrooms closed to allow everyone to fully recharge. Ultimately, the decision should be made based on the well-being and needs of the students and staff. **

Learning spaces are flexible, adaptable environments that can accommodate a variety of teaching and learning styles, while classrooms are more traditional, fixed spaces designed for instruction.

Learning spaces prioritize student-centered learning and can be used for a variety of purposes, while classrooms are primarily used for formal instruction. **

In the German debate, there are differing opinions on whether classrooms should be assigned to subjects or teachers. Some argue that assigning classrooms to subjects allows for better organization and ensures that the necessary resources are available for each lesson. On the other hand, others believe that assigning classrooms to teachers promotes a sense of ownership and allows teachers to personalize their learning environment. Ultimately, the decision may depend on the specific needs and preferences of the school and its staff. **

It depends on the specific policies of the teacher and the school. Some teachers may mark a student as absent if they miss a class due to a classroom change, while others may not.

Ultimately, it's up to the teacher's discretion and the school's policies. **
