Good Mentoring offers an in-depth analysis of the way mentors transmit not only knowledge and skills but the guiding values that support good work and social responsibility. The book clearly shows how these values are passed along to those they guide. Profiling three lineages of scientists passing their professional skills, values, and practices down through generations, the book reveals what constitutes successful mentoring in science and beyond. Stemming from a first-of-its-kind study by the GoodWork Project, the book shows how the cultivation of professional ethics and excellence depends on teachers and mentors and the learning environments they foster.
