I suppose I was lucky enough to be educated at a time when teachers still thought children could handle knowledge. They trusted us. Then there came a time when they decided that because not every kid in the class could understand or remember those things they wouldn't teach them anymore because it wasn't fair on the less good ones. So they withheld knowledge. Then I suppose the next lot of teachers didn't have the knowledge to withhold.
The author reflects on a past educational experience where teachers believed in the capacity of students to absorb complex knowledge. This environment fostered trust in students and encouraged learning, as teachers imparted a wealth of information without reservations.
However, a shift occurred in educational philosophy; teachers began to withhold challenging content, believing it was unfair to those who struggled. This led to a generation of educators who, lacking the depth of knowledge to share, further perpetuated a cycle of limited learning opportunities for all students.
