Chemcom after a decade. A look backward and forward

Resumen

Science education at the secondary leve1 (grades 10-12) in the United States of America is very different than in most other countries. During pre-secondary and secondary (high) school in most countries, students are taught biology, chemistry, and physics principles together for several years. This continuum approach appropriately builds on basic principles learned previously, and also provides opportunities for students to make connections and discover relationships among the three sciences.
