Very Simple and Inexpensive System for Distance Learning with the Use of Chalkboard

Abstract

Using technology in Covid-19 time’s classroom is a given. Many teachers, however, prefer to use chalkboards both because they have difficulty adapting to new methods and because they believe teaching with a chalkboard is more effective. Writing with chalk on a blackboard makes it easier to control the pace of a lecture because it induces to talk while writing, thus giving to the students the time to assimilate new information and to take notes properly. To make it possible for teachers to continue lecturing with this method but in distance learning mode, as required by the anti-Covid-19 provisions, an easy and inexpensive automatic shooting system has been developed, that can be used by schools and universities with minimum effort. To take advantage of the developed software, it is sufficient to have a smartphone (or a webcam) and a PC, without the need for other expensive hardware. The method has been experimented and found to be very effective in our department with a number of colleagues completely relying on it to deliver classes.
