John Dewey, an influential American philosopher and educational reformer, emphasized that children have a wide range of natural interests that should be nurtured in the learning process. According to Dewey, children are inherently curious and engaged in various activities that reflect their developmental needs and interests. These include:
- Interest in talking: Children are naturally social beings who express themselves through language. Talking helps them communicate, explore ideas, and build relationships.
- Interest in creating: Children have a strong inclination toward creativity. They enjoy building, making, and experimenting with materials, which fosters their imagination and problem-solving skills.
- Interest in artistic expression: Dewey believed that art is a fundamental part of human experience. Children express themselves through drawing, painting, music, and other forms of artistic expression, which helps develop their creativity and emotional intelligence.
Thus, all three interests—talking, creating, and artistic expression—are important aspects of childhood development, as highlighted by Dewey.
