Testimonials

We work with amazing educators

“I have been teaching Java classes for 9 years and AP Computer Science A for the past 5 years and I have used a number of different curriculums along the way. COBI is by far my favorite. I can easily see where my students are at with the gradebook feature. The information on the article slides prepares students well for the practice problems. The videos are concise and helpful. The editor allows me to quickly jump from information to demonstration. The interface and look of the COBI site is really nice, up-to-date feeling, and incredibly easy to navigate for both me and the students. I have found COBI to be a great resource for my classes.”

Dennis Hjort

Saint Ignatius High School

“The platform is easy to use and the live onboarding sessions helped us get started right away. This resource provides the rigor we were looking for and keeps students actively engaged in learning.”

Denise Ayres

Temple Independent School District

“The PD course gave me a clear understanding of the topics and it was fun to watch the videos. And the best thing - I passed the FTCE CS exam! The course helped me a lot. I highly recommend the PD course.”

Bonnie Yu

South Walton High School

“This course gave me exactly what I wanted: a thorough overview of the content of AP CS Principles without having to learn every detail. This was very valuable to me.”

Tricia Kellison

The Girls' Middle School

“The course breaks down concepts in a way that makes it easy for my students to understand.”

Cory Houghton

Earlham County High School

“Great videos, excellent problem solving tutorials and mix of quizzes and tests.”

Tony Finelli

Cherokee Bluff High School

“This PD accomplished two major things: I learned to set up and use a Raspberry Pi, and I learned how to teach it, including introductory CS content for students and misconceptions students have when learning to code. I'd recommend this PD to anyone who wants to start or improve teaching CS concepts and physical computing.”

Janet Weaver

Our Lady of the Gulf Catholic School

“Excellent questions that match the real exam content.”
