TeachCyber, a subsidiary of DARK Enterprises Inc., is a non-profit dedicated to developing, supporting, and stewarding excellent cybersecurity education at the secondary level. Our mission is to provide resources, training, and support to secondary school educators teaching cybersecurity. By supporting teachers, we hope to 1) contribute to growing the cybersecurity workforce; and 2) help all students understand ways to act more safely and more ethically in cyberspace. Teach Cyber is by educators and for educators. What is Teach Cyber? Simply put, it is teaching materials for educators interested, excited, and ready to teach high school cybersecurity. The Teach Cyber courseware is creative commons licensed giving educators the rights to adopt, adapt, and disseminate the Teach Cyber course. The Teach Cyber course is based on the High School Cybersecurity Curriculum Guidelines (HSCCG). The Guidelines and the Teach Cyber curriculum were developed by a team of K-12 educators, post-secondary educators, and cybersecurity experts in partnership with the National Cryptologic Museum Foundation. The instructional materials are grounded in learning science, and use a variety of hands-on, active, student-centered learning strategies, including lab experiences using the U.S. Cyber Range. Currently educators in Maryland, New Hampshire, and Texas are pilot testing the materials with a final version to be published for the 2021 AY. The Teach Cyber team is partnering with several states to support their teachers as they adopt the High School Cybersecurity Curriculum Guidelines and the Teach Cyber instructional materials. If you are interested in this effort, you can 1) sign up to pilot test in Spring 2021, and 2) sign up for the newsletter to receive updates. Teach Cyber welcomes partners and sponsors as well.
