    A mathematical modeling activity in elementary school with authentic data about COVID-19
    (2022) Trelles Zambrano, Cesar Augusto
    The aim of this study is to analyze a mathematical modeling task developed by students in the sixth grade of primary education (11-12 years old) based on a model-eliciting activity with real statistical data about COVID-19, which was implemented online during the period of confinement in Spain. Based on a multiple case study, the final products generated by the students are analyzed. The results show that, although not all students are able to develop a model, those who do are able to use intuitive concepts of statistics and probability that are outside the regular curriculum. It is concluded that these activities develop mathematical skills but require pedagogical knowledge to incorporate them frequently and successfully into teaching practice.

    Design, construction and validation of a rubric to evaluate mathematical modelling in school education
    (2022) Alsina, Ángel
    This study describes the design, construction and validation of a rubric for assessing mathematical modelling processes throughout schooling (3–18 years), especially those oriented by modelling cycles. The final version of the “Rubric for Evaluating Mathematical Modelling Processes” (REMMP) consists of seven elements with their respective performance criteria or items, corresponding to the different phases of a modelling cycle. We concluded that REMMP can be used by both researchers and teachers at different educational levels from kindergarten to high school. The rubric is designed to assess group work developed by students; however, it can eventually be used individually.

    Implementation of a didactic situation of linear programming through geogebra software
    (Institute of Electrical and Electronics Engineers, 2019) Trelles Zambrano, Cesar Augusto; Toalongo, Ximena; Gonzáles Prado, Neli Norma
    The present work exposes the main results of the application of a linear programming activity through the use of Geogebra software developed with future teachers of mathematics, this activity has been designed under the approach of the Theory of the Didactic Situations. The objective of the activity was to determine how the use of Geogebra software can influence the better understanding of mathematical knowledge related to linear programming in future teachers. The results show that the design of an appropriate activity in combination with the use of software offer great advantages both to teachers and students to acquire and consolidate the main mathematical knowledge. © 2019 IEEE.
