Teachers in K-12 schools have shown an increasing desire for open educational resources (OER) to ensure all students can learn effectively. OER provide teachers with free access to open-licensed educational resources that they can retain, reuse, revise, remix, and redistribute for personalized instruction. Open educational practices (OEP) have been considered a pathway to reinforce the acceptance and readiness of K-12 teachers to use OER. This research thus showcases a qualitative study that investigates teachers' experiences with OEP. This research explains K-12 teachers' perceived benefits of implementing OER and also discusses their perceived barriers hindering OER usage in K-12 settings. The study also discusses the practical implications of integrating OER in K-12 curriculum.
