Abstract
The teachers^ lack of knowledge about the use and use of mathematical formulas and concepts in
solving problems in everyday life results in students not knowing the role, benefits, and importance of
mathematics material taught by teachers in schools. As a result, students often perceive mathematics as only
theoretical, difficult, boring, and uninteresting to learn. Determining the number of people
infected with Covid 19 in schools in the future is one of the problems that can be modeled mathematically.
The dynamic system model In+1=1,1177482 In - 0,000196247 In2 that can be used to predict the number of
infected students in the next few days is constructed with the assumption that there is an interaction between
students and students who are vulnerable to the Covid virus. A model that uses the concept of change = future
value - present value and the proportionality relation is constructed through several stages or modeling steps.
These stages are problem identification, making assumptions, determining variables and relationships
between variables, constructing models or mathematical equations, determining the solution of the model, and
testing the validity of the model. From the results of the validity test, it was found that the model was closed
to the data. This means that the model constructed can be declared valid. Besides, from the resulting model, it can be concluded that the mathematics material taught in schools and related to Covid 19 is quadratic
equations, functions, and sequences. From this activity, the teacher can also find out the application of some
of the mathematics material taught so far. Then this knowledge can be passed on to students at school.
Keywords: proportionality relation, mathematical model, validity test
