An instructional supply could be a book, it could be a whiteboard, it could be flexible seating, it could be a fidget spinner, it could even be painting the walls of a school a more calming color, allowing students to thrive.
Bahan ajar bisa jadi sebuah buku, sebuah papan tulis spidol, tempat duduk fleksibel, fidget spinner, atau mungkin mengecat dinding sekolah dengan warna menenangkan, agar murid-murid merasa nyaman.
