With hands-on teaching the students are doing it themselves with the guidance of the teacher. I believe that a child must use scientific inquiry to gain knowledge. To do this, a child must acquire information through experience and examine it. A teacher can lecture information to a student and nothing is retained, but let the student experience the subject matter and he will retain it. Education allows people to make their own decisions and determine what is best for them.
People learn from their experiences, good or bad.
From learning from out experiences we can determine what our actions will be in the future. A bad experience in one subject can have a negative impact on the student. I dislike English because of my bad experience with it. I enjoy math and history because my experiences were positive. I want the students to experience different aspects of the subject matter and then one aspect will stick with them.
