Resumen: En el presente trabajo, se realiza un modelo computacional mediante los Autómatas Celulares (Cell-DEVS) que describa la dinámica de transmisión de la Varicela en un grupo cerrado de personas donde se pueda propagar la enfermedad. Desde la perspectiva de la epidemiología matemática se tiene el modelo matemático SEIR de W. O. Kermack y A. G. McKendrick que representa la dinámica de la epidemia, en nuestro caso la Varicela, donde se realizará las simulaciones computacionales tanto por los Métodos Numéricos como los Autómatas Celulares para analizar el desarrollo de la enfermedad. Palabras clave: epidemiología matemática; ecuaciones diferenciales; autómatas celulares; formalismo DEVS; simulaciones computacionales.

The process of Teaching and Learning in times of Covid-19 brought experiences between teachers and students, seeking to improve with some teaching method to obtain satisfaction in their learning, the objective of this research is to validate the instrument of measurement of Teaching and Learning Experience Questionnaire (ETLQ) in the Peruvian context with university students, This instrument consists of three parts, the Teaching and Learning Environment which consists of 19 questions, the Student Learning Approach which consists of 9 questions and the Critical Thinking with 4 questions, each question is composed of 5-point Likert-type scales (1 point = "Strongly disagree" and 5 points = "Strongly agree". A total of 2027 university students participated throughout Peru, including students from national and private universities. Cronbach's Alpha =0.957 with 32 numbers of items was valid for its respective use, with which it will be possible to measure the Learning Experiences in university students, reinforcing this result with different tests whose results were optimal and reliability analysis. Concluding that, the validation instrument is valid in the Peruvian environment, online education is accepted in its highest percentage and that the rejection of this is only in the most vulnerable students and the feedback to students is the most outstanding. Keywords—Validation, Learning experiences, teaching, online education, Covid-19
