Homework is overlooked as one of the biggest stress causes and plays the biggest role in student depression. It kills motivation and ambition. Multiple classes giving homework to every student every night for the next 10 years of their lives is not the best way to educate our youth.
By banning homework we can create more class time for discussion and real, authentic teaching. Giving an overview of a lesson and then assigning work for the students to do at home is not teaching. Eliminating homework creates a healthy environment for all students.
This also benefits teachers. When teaching a class, they are restricted on time and therefore give out homework expecting the students to have it finished by themselves. This could change everything and introduce an era of genuine education.
