I wanted to share this statewide resource I developed last year as Science Coordinator at the Orange County Department of Education. Prior to my retirement last July, I had trained over 200 “trainer of trainers” throughout the state on how to use this online resource that provides step-by-step instructions and graphics on how to develop an NGSS instructional unit. Since then, I have used this online tool and backwards mapping protocol with many districts I have consulted with. My next step is to collect and archive sample units from participating teachers. I hope you try this tool out and find it useful!
