| Revolution in Earth and Space Science Education - Brief History of Earth Science Education (1495 words) |
 | While elements of geology, astronomy, physical geography, and environmental sciences were taught in schools at the turn of the 20th century, today's Earth science courses are a recent addition to K-12 education. |
| Science teaching at academies, however, was not always of high quality and often consisted of courses as short as six weeks, with inadequately prepared teachers and poor or non-existent textbooks. |
| The 219 remaining chapters were coded to match the four Earth science themes resulting in 120 chapters devoted to geology, 34 to meteorology, 23 to oceanography, and 42 to space sciences. |
