Order ECHOS  |  


The ECHOS preschool science curriculum consists of nine thematic units. Each unit contains an Overview, Science Process Skills, Lessons at a Glance, Key Concepts, Lesson Guide, four science lessons, a storybook and 12 Integration Cards (iCards) that provide activities related to language and literacy, mathematics and creative arts.


The ECHOS Observation Tool measures teachers' use of instructional strategies and children's use of science process skills. Observers can use the electronic, browser-based version of this tool on their smartphone, tablet or laptop to capture interactions between the teacher and a small group of children.

In addition, the tool provides a set of questions related to fidelity, the degree of congruence to the design of the ECHOS® program. It's used to check on curriculum-specific aspects including: sequencing of lessons, working with small groups, reinforcing key concepts, ease of lesson delivery, child engagement, etc.
