For this particular project we will use Anki, a free and open source software developed by Damien Elmes based on the SM2 algorithm . It works on the basis of cards created using HTML, which can include text, images, sounds, videos and LaTeX equations. The type of activity contained in the card can be of many different types, but always looking for a proactive response from the student, rather than a mere reading, to properly reinforce the knowledge. Depending on the difficulty the student had to remember the answer, the software calculates how much time has to pass until the question is displayed again, so that the probability of correctly remembering the concept studied is not lower than a certain threshold, according to the forgetting curve, thus making the long-term retention increasingly higher.
