Target group
I hope to see critical thinking become a common part of children's education, not something treated as an optional extra or reserved for adults. I also want critical thinking education to be fun and relatable. Through stories and interactive adventures, I hope to show that children can learn about fallacies, data analysis, and media literacy in a way that is both engaging and accessible.

About the innovation

Why did you create this innovation?

In 2019, I was teaching science at an international school in Chiang Mai. My grade 7 students were learning about atoms. After class one day, a boy asked me about flat earth. He had heard flat earth claims from a basketball player and then visited some flat earth sites. The arguments were persuading him. We talked about it, and it turned out okay, but I wondered what would have happened if he hadn't come to an adult. With the number of claims kids encounter every day, both online and offline, it's hard to teach facts fast enough. That's why I also believe it's important to teach kids the skill of evaluating claims: how to find trustworthy sources, fact-check, and withhold judgment when there isn't enough information. In other words, kids need critical thinking. I started to teach it to my students, but struggled to find engaging resources to support me. That's why I decided to make my own.

What does your innovation look like in practice?

Critikid's online courses are designed for independent, self-paced learning and can be used both at home and in classrooms.

For home use, parents purchase access to individual courses, and children work through them at their own pace. Although parental guidance is not required, many parents choose to do the courses alongside their children. Resources purchased this way come with lifetime access, but they can only be used by one child at a time.

For classroom use, Critikid offers a "For Schools" subscription that allows teachers to add an unlimited number of students to each classroom. Students complete the lessons independently, while teachers can extend the learning with accompanying lesson plans, worksheets, and classroom activities.

How has it been spreading?

People are learning about Critikid primarily through social media, search engine results, and ChatGPT.

How have you modified or added to your innovation?

Critikid used to focus on selling to parents and homeschool families, but we recently added the "For Schools" subscription model to make the courses easier to use in a classroom setting.

If I want to try it, what should I do?
