    Tensiones al enseñar inferencia estadística en la formación inicial docente
    (2022) Giaconi, Valentina; Montenegro, Helena; Rojas Sateler, Francisco; Catalán, Marco; Guiñez, Flavio
    Este estudio examina las tensiones que vivencia una formadora de profesores al enseñar inferencia estadística, tópico en el que se han reconocido diversas dificultades de enseñanza y apren-dizaje en la formación inicial del profesorado de Matemática de secundaria. Para ello, se utilizó un enfoque cualitativo de naturaleza interpretativa, donde se analizaron las reflexiones de la formadora sobre la enseñanza de una unidad de inferencia estadística registradas por medio de bitácoras y reunio-nes de amistad crítica. El análisis permitió identificar tres grandes tensiones: una de ellas relacionada con la estadística como disciplina; la segunda, vinculada a su enseñanza; y la tercera, asociada con el aprendizaje de los estudiantes. Finalmente, se discuten posibles mejoras de los procesos formativos en la formación inicial del profesorado.

    Understanding the influence of children's mental health, cognitive development, and environmental factors on learning outcomes in Chile
    (2024) Gomez, Gabriela; Rivas, Marlene; Giaconi, Valentina; Martinez, Camila; Burrone, Maria Soledad
    Mental health, cognitive development, and social background are related to educational success. While growing evidence is available in cultural settings other than Western countries, more knowledge is needed, especially regarding interactions among these dimensions. Rather than studying isolated factors, we propose an integrated approach to consider the diverse interrelated dimensions influencing children's learning. Life course theory supports this approach underlying the role of early events in subsequent life paths and the multidisciplinary nature of these events. The sample consisted of 610 children (49.1% male) attending first grade. The children completed reading, mathematics, and visuospatial working memory (VWM) assessments. Parents completed the Strengths and Difficulties Questionnaire (SDQ-P) and reported their demographic information. A multilevel path model was estimated, including direct relationships between (i) children's socioemotional behavior (SEB) and learning, (ii) VWM and learning, and (iii) SEB and VWM. The effects of sex and maternal education were also controlled. School and student level variances were modeled. At the school level, VWM, reading, and mathematics have variance, whereas SEB does not. At the student level, VWM, SEB, and maternal education have significant and differential effects on learning. Hyperactivity and peer problems were negatively related to reading and mathematics, while emotional problems were not, and conduct problems exhibited mixed results. These results reinforce developmental life course approaches, that is, from the beginning of schooling, promoting positive mental health can improve children's learning outcomes.
