Adults thinking back on their experience of school almost always remember with most gratitude the teachers who taught them more than just a subject, and prepared them for life, not just for an exam. But the current generation of students may not have the same experiences to look back on in future years because the role of teachers has changed. The focus for both students and teachers is now mainly on exam results, and that is how their success or failure is measured. For teachers to share their lives with their students, offering them a model of adulthood to which to aspire, is therefore no longer considered desirable. So children today receive a less valuable education than their parents and grandparents did.
