“…There is research into maths competency indicating that boys tend to get better results (Preckel et al, 2008;Llor et al, 2012; (González-Pienda et al, 2012;Mato et al, 2014;Ministerio de Educación, Cultura y Deporte, 2014b;Preckel et al, 2008;Ministerio de Educación y Formación Profesional, 2019;Cueli et al, 2020;Palomares-Ruiz and García-Perales, 2020), girls can exhibit anxiety and lack confidence in this area (Instituto Nacional de Evaluación Educativa, 2013;Rodríguez-Mantilla et al, 2018). It is essential to consider girls' levels of attention or execution rates in approaching mathematical tasks (Boaler, 2016;Farfán and Simón, 2017;Hattie et al, 2017;Rodríguez and Guzmán, 2018;Cueli et al, 2020), as well as other motivational and emotional factors (Else-Quest et al, 2010;Rodríguez-Mantilla et al, 2018). Teacher training and practice must consider these discrepancies between aptitude and attitude toward mathematics (Nortes and Nortes, 2013;Rico et al, 2014;Ursini and Ramírez-Mercado, 2017).…”
