An OER science curriculum has completely revolutionized the way I teach and has transformed the way my students relate to their learning. In fact, some of the most powerful learning in my middle school science classroom has happened when I’ve pretended to NOT know the “right answer.” That’s when students take the lead and start to offer up their own ideas, share their experiences, and make powerful connections—sometimes amazing ones that I would never have thought of. Teaching in this way requires a good deal of flexibility—including in your curriculum. A traditional science textbook doesn’t always provide educators the freedom to delve into topics that students bring up from their own lives or questions they have about the world around them. That’s why I’ve turned to open educational resources (OER).
