This is the most important lesson which kids learn in a STEM course, it takes away the fear out of them about trying & learning new things and to learn things by making mistakes which our school system doesn’t believe in. You cannot afford to make mistakes in school, you cannot fail, you cannot give a wrong answer, mistakes are not appreciated. You have to be always right which is not real. In life we learn more by making mistakes & number of mistakes made is a barometer of number of new things we have learned and that’s what a STEM course teaches your kids.
