The main idea explored in the article is about how supervision in education can help achieve educational goals. Initially, a directive approach was commonly used but was found ineffective in giving teachers room to grow and be creative. This led to the emergence of non-directive supervision theory. The problem with directive supervision was that it put too much responsibility on the supervisor, making them dominant and hindering teacher development. The research indicates that non-directive supervision could be a better approach for improving education by giving teachers more freedom to enhance their skills and creativity.
