Yes, showing is definitely better than telling in education. When teachers use visuals or demonstrations, it makes the class more interesting. Students can actually see how things work instead of just imagining them. This can help them understand and remember the lessons better. Also, for students who are not good at learning by listening, this method can be really helpful.

I don't think showing is always the best method in education. Some subjects, like literature or philosophy, rely heavily on reading and critical thinking. These areas require a deep engagement with text and ideas that can't always be 'shown'. Also, trying to show every concept might oversimplify things, which isn't good for students who need to tackle complex ideas.

It really depends on the situation. Different subjects and different students might need different methods. For example, young children or visual learners might benefit more from showing, while older students or those studying complex theories might need more detailed explanations. A mix of both showing and telling might work best, adapting to what's being taught and who is being taught.
