Some Additional Resources
Advanced mathematics courses are difficult, and you will be challenged
in many ways throughout this course. Research has shown that the students that are the
most successful are the ones who have two qualities: Growth Mindset and
Grit. View, read, and watch the following resources on Growth Mindset
and Grit. Throughout the course, do your best to keep these ideas in mind as you encounter
difficult portions of the material.
- Growth Mindset is the belief that your ability to learn is not fixed, that
you become better at any subject with effort and practice, and that failure is not
permanent.
- Grit is the ability to stick with and pursue a goal over a long period of
time. This includes the ability to stay determined and motivated
despite experiences with failure or adversity.
