This book provides examples of how K-12 teachers and other instructors improve their instruction. Their stories illustrate that they do not follow the tenets of the social science improvement paradigm, which was proposed by education professors in the 1950s and has been promoted by policymakers since the 1970s. Instead, these stories illustrate that teachers improve instruction by bringing the six virtues of the educated person to their dealings with students. In other words, their stories illustrate an aesthetic improvement paradigm.
