Oldie here! I went to primary school in the sixties. We had to stand up for the teacher, work in silence and copy off the board. We were slapped by the teacher if spelling was incorrect, and told to stand in a corner, facing the wall, if we misbehaved (irrespective of whether it was our fault or not). We ran around in our knickers and vests to 'Music and Movement', and I dreaded the outdoor PE on scratchy coconut mats in gravel coated playgrounds.
As others have said, some children hated school; others loved it If I look back on the school experience, it was horrendous by today's standards. However, the experience I describe was normal for a village school in those days.
I think, if children went back to be taught by the methods that were acceptable a generation ago, they would be shocked. Go back two generations, and the experience would be unacceptable.
The teaching methods, technology and individuality available to children today, in schools, is magical compared to those experienced over fifty years ago.
However, I think what really matters, and what children of any generation remember are the friendships made, the kindness of a teacher, the time we did something really well, or the bullying, the discrimination or unfairness and the time we were made to feel inadequate. These memories are timeless and not context dependent. So school has always been, and will continue to be, enjoyable for some and less enjoyable for others, dependent on human relationships, rather than pedagogic practice.
