• Resumen

  • The study of astronomy is vast both in space and time. A typical astronomy course leads students through the entire 14 billion-year evolution of our universe while covering everything from atoms to planets and stars to galaxies. To students, the 15-week tour of the universe is often little more than a series of facts and figures related to objects beyond reach or comprehension; there is little connection to their human story. Even worse, the desire to cover so many topics in the course results in students memorizing properties and processes of ever-larger and ever-more-distant objects without comprehending the empirical nature of astronomy. To them, our understanding of the universe seems fixed, not fluid. while students may learn the story of the physical universe, they fail to appreciate how our understanding of our human place in the cosmos has changed over time.
