ABSTRACT
The teaching of mathematics is a complex phenomenon by nature and one that the COVID-19 pandemic has increased. Classes' features or the characteristics of classes held in confinement and the curricular prioritization carried out by the Ministry of Education, make necessary tools that allow evaluating teaching during this time, to improve, strengthen the learning of students. Through a review of the dimensions that characterize the quality of mathematics teaching, we identified four common elements (math used in class, goals, classes, and assessment). The description of these elements through questions is an input to evaluate the mathematics classes carried out in this very particular academic year. We conclude that the characteristics of the Chilean educational system make it necessary for the evaluation of mathematics classes to also be carried out from the perspective of how the educational system itself provided the conditions for teachers to carry out the quality teaching.
