An "exemplar" is a model or example that serves as a standard for others to follow. It can represent the best qualities or characteristics of a particular category, making it a useful reference in various fields, such as education, art, and science. Exemplar models help individuals understand what is expected or desired in a specific context. In education, teachers often use exemplars to demonstrate high-quality work to students. This can include sample essays, projects, or performances that showcase the criteria for success. By studying these exemplars, students can learn how to improve their own work and achieve better results.
