SCALES is a signage plan we designed for a private cram school for children who are no longer familiar with compulsory education. Based on the concept of “growth ruler,” we installed at the entrance a continuous RC pillar as a ruler, with 9 dimensional units. These include millimeters, centimeters, meters, yards, feet, inches, measure, and distance. Furthermore, everything from room numbers, lockers, elevator floor displays, and toilet signs all use the ruler and grid motif. Through such signage, students learn through a fun, hands-on experience by creating opportunities for active learning, to become more aware in everyday spaces, such as perceiving and recognizing their height in various units that they were originally not familiar with.
