When it comes to mathematics, students often have fixed mindset. A person with a fixed mindset views intelligence as something that is given to them: they either have it or they do not. They either think "I'm really smart, and math is easy for me" or "I've just never been good at math." The Fixed Mindset is not only harmful to your intellectual development, but it is also inaccurate. Research by educational psychologists have shown that the human brain is flexible and intelligence is not fixed.
