I believe this is especially true for students. If students start to show verbal negativity or resistance to trying new things, it may be that they are afraid to fail. It shows up in student self-talk (i.e. "I can do it" versus "I'll never get it" or "Let's try" versus "It'll never work"). As teachers and parents, we must promote this idea early on by modeling a growth mindset through our words and actions.
I encourage you to have ongoing discussions with your kids about not being afraid to make mistakes. It's how we learn. If you use Responsive Classroom like I do, I introduced the topic during one of our Morning Meetings. I let kids talk about a time when they made a mistake they learned from with a partner before sharing in our class circle. I made sure to write down some of these "learning mistakes" on a poster. It was so sweet to see kids later referring to the poster to cheer up their friends when they made a mistake they felt embarrassed or frustrated about.
Note: Building a growth mindset is a process. Students need the right activities, feedback, and encouragement over time to build a growth mindset. A storybook is only one piece of the puzzle.
