"Is het voor een cijfer?" by Johannes Visser offers an insightful analysis of how the emphasis on grades in education can undermine the learning process over time. Visser argues that this focus leads to decreased intrinsic motivation among students and negatively impacts their emotional well-being due to the constant pressure to perform.

The book delves into alternative approaches to learning that prioritize student engagement and intrinsic motivation. Visser highlights the importance of creating an educational environment where students are motivated by curiosity and a genuine interest in the subject matter, rather than by the pursuit of grades. He also discusses practical strategies for educators to implement these changes, such as providing personalized feedback instead of grades.

In the concluding chapters, Visser makes a compelling appeal to young people to join student organizations and advocate for more effective and supportive educational practices.
