From my experience of teaching physics and chemistry to boys and girls in the
same classroom for nine years I do not think that there are gender differences in
the learning of science. What I observed were differences in student interests.
Some enjoyed one topic more than another topic. Some chose to write about one
project, others chose a different project. I had both girls and boys obtaining very
good marks and others obtaining less good marks. Some girls and boys were
emotionally disturbed and could not learn. But there was no gender difference in
this either
