According to Björn Öckert, the research shows that students in smaller classes learn more and also did better later in life than students who went to larger classes.
- It is costly to reduce the class size, because then you have to hire more teachers, he says.
Even today's shortage of teachers makes it difficult in many places to teach in small groups.
More teachers are needed, but the question is how to attract more people to the profession.
Ulf Fredriksson has looked at how Sweden and Finland differ in the status and education of the teaching profession.
In Finland, competition for training places is greater, while in working life they have a higher salary than Swedish teachers.
Low admission threshold for teacher education
Salary plays a role in attracting more people to the profession, but is far from the only factor, according to Fredriksson.
- The school is discussed as a problem area.
It is important that teachers feel that they are appreciated by society, not only financially but also in other ways.
Good support from the management, extra resources and the opportunity to have the opportunity to grow in their profession, says Ulf Fredriksson.
It can also be a challenge to maintain the quality of teachers in the coming years, Fredriksson believes.
This is not least due to the low admission threshold for teacher education.
- It has been low for many years.
Students can come in without particularly high grades, he says.
