The project method is an instructional approach where students apply the skills and knowledge they have learned to solve real-world problems with minimal teacher direction. Introduced in the 18th century for architecture and engineering students, it was later expanded by William Heard Kilpatrick to be a child-centered, progressive philosophy of education. While time-consuming, the project method gives students hands-on experience, enhances their skills, and allows them to be creative and imaginative. However, it can isolate students to a single activity for long periods.
