In this paper I shall present ways in which professional astronomers in developing nations can aid basic education by using a few things that have been done in Mexico.
Recently the compulsory education in Mexico was increased from 6 to 12 years. An optional subject on astronomy was included in high school; so there are several ways in which one can contribute to the national education system.
I shall give a practical example on ways to teach and mention the importance of magazines and books dedicated to teachers. I will also address the way we have implemented brief courses for educators and organized conferences for science teachers.
It is important to emphasize that we must find ways to train people in a more effective way.
