The findings of a recent survey suggests that students are not happy with
multimedia approaches in education. They feel that they learn much effectively
when traditional methods are used. The students interviewing said they thought
the teacher played a important role in their learning. They found listening to the
teacher, taking note, and using a textbook suitable for their age group really
help them understand and remember the content of their lessons. They also
found that answering questions that had been written on the board very helpfully. They valued the chance to carry practical, hands-on work, either.
