25. Integración de las Etnomatemáticas en el Aula de Matemáticas: posibilidades y limitaciones
Abstract This paper presents the first part of a doctoral research about teacher's training, focused on Ethnomathematics. It analyzed the veracity of two conjectures: C1. Teachers do not recognize mathematical extracurricular activities as math, and C2. This conviction obstructs the use of this knowledge in the classroom. Starting from these conjectures, we

26. Automated sugar analysis
Abstract Sugarcane monosaccharides are reducing sugars, and classical analytical methodologies (Lane-Eynon, Benedict, complexometric-EDTA, Luff-Schoorl, Musson-Walker, Somogyi-Nelson) are based on reducing copper ions in alkaline solutions. In Brazil, certain factories use Lane-Eynon, others use the equipment referred to as “REDUTEC”, and additional fact

27. Validación de la Versión en Español del Mathematics Value Inventory (MVI) entre Estudiantes Universitarios Uruguayos
AbstractBased on the expectancy-value theory, the Mathematics Value Inventory (MVI) was intended to measure math value in four areas: interest, utility, achievement and personal cost. This paper presents the validation of the Spanish version among Uruguayan university students: factorial validity through confirmatory factor analysis (CFA), gender related dif

28. Diseños Prehispánicos, Movimientos y Transformaciones en el Círculo y Formación Inicial de Profesores
AbstractInitially, an analysis of the logic design was used on plates or cups of pre-Hispanic cultures of the Grass, or Quillacingas, located south of Colombia. The results of this approach led to the construction of some activities to classes under the heading of movements and transformations in the circle. The main objective was to raise a methodological p

29. Conocimiento Especializado de un Profesor de Matemáticas de Educación Primaria al Enseñar los Números Racionales
We describe the specialized knowledge of an expert Primary Education math teacher while teaching the topic of rational numbers to students of 11-12 years old. Using a category system of the subdomains of the Mathematics Teacher's Specialized Knowledge model (MTSK), a content analysis of the transcripts of 21 classes taught was performed. This allowed us to a
