Secondly, the focus of learning is on the process and how the content is learned, rather than on the final product. Discovery learning focuses on how to analyze and interpret information in order to understand what is being learned. In traditional teaching and learning a lot of times the focus is on recalling information by rote memorization. This type of process oriented learning can be applied to many different topics instead of producing one correct answer for a specific question in a specific topic. Students will achieve a much deeper level of understanding in discovery learning. The emphasis is placed on mastery and application of overarching skills .Thirdly, failure in discovery learning is seen as a positive circumstance . Failure in discovery learning is related to a unique lesson learned from Thomas Edison. Edison is said to have tried as many as 1,200 designs for light bulbs before he found one that actually worked. When asked if he felt discouraged from all this failure, Edison responded by saying he never felt discouraged because he learned so many designs that didn't work. Discovery learning does not stress finding the correct answers each time. Cognitive psychologists have shown that failure is central to learning. In fact, if the student does not fail while learning, the student probably has not learned something new.
