Regarding programming education in universities, it was common to utilize computer classrooms until now. Bring your own device (BYOD) spread, and students brought notebook PCs they purchased into a lecture room to take a class recently. A projector and screen were installed in the classroom. The teacher displayed a picture of the textbook he had photographed with a painting and calligraphic work camera on screen using a projector. The teacher displayed the state of the desktop notebook PC that he operates. In a lengthwise classroom, reading a letter from the rear of the classroom was difficult and created an issue. It was the entire school that introduced Zoom in February 2020 to address this challenge. In this review, I describe the new classroom AV systems and Digital Textbook in computer programming education.
