The existence of the hierarchy of life is assumed in all instructional materials in biology in K-12 but its origin and evolution are not being taught. ETIs allow teaching the origin and evolution of the hierarchy of life. We developed a 3-step approach to translating our ETI research into the classroom for teaching biological complexity and the hierarchy of life: i) define new content material, ii) develop new teaching tools (5 specific tools were developed) and (iii) interface with the local teaching environment including local standards.
Our framework is published in Evolution, with follow-up papers under revision in major biology education journals. A two-year middle school study showed promising results, and we are developing a K-12 teaching progression. Analysis of our study data will be included in an upcoming publication.
We have developed several teaching modules to be used in a classroom setting. They are currently in use in the Tucson Unified School District.
