    (Universidad de Córdoba, 2024-08-21) De La Ossa Doria, Kevin; Torres Hoyos, Francisco; Catellano, Maria Esperanza; Martines, Segundo; De La Ossa, Kevin
    En América Latina en el año 2018 se diagnosticaron 462.000 canceres de mama en mujeres (Pan American Health Organization, 2018), mientras que en Colombia el diagnóstico en el mismo año fue de 1.270 casos (Bravo y Mu˜noz, 2018; Pardo, et al., 2017). Lo que sitúa este cáncer en la tercera causa de muerte de todos los existentes (Martínez-Rojas, 2018; Mejía,et al., 2019). Existen muchas t´ecnicas imanológicas que permiten la detecci´on y diagnóstico del cáncer de mama, como son mamografía, resonancia mágnetica, ecografía y tomagrafía computacional (TAC). Tambi´en existe la t´ecnica del tacto de mama, que permite localizar algunos tipos de tumores. Teniendo en cuenta la gran importancia de estudiar este tipo de neoplasias malignas, en el presente trabajo se hace un estudio que permite el diagnóstico del cáncer de mama, mediante el procesamiento de imágenes de tomografía y el mátodo de algoritmo de clauster cu´antico, que permita estadificar el grado de malignidad de la lesión, donde podamos mostrar que los resultados concuerdan con los reportados en la literatura.

    Estrategias metacognitivas para el desarrollo de competencias digitales en la construcción participativa de presentaciones infográficas con estudiantes de básica secundaria
    (2023-07-13) Betancourt Negrete, Elian David; Pino Espitia, Laura Johana; Meza Fernández, Johana Milena; Ever Coronado Martínez
    LThis research project aims to design a meta-cognitive strategy based on the participatory construction of Infographic Presentations for the development of digital competences in secondary school students at San José Educational Institution in Montería, Colombia. A discrepancy has been identified between the institutional vision of forming students with digital skills and the educational practice. This has led to a lack of resources, environments, and strategies that promote the development of digital and technological competences in students. Additionally, the COVID-19 pandemic has disrupted projects and educational activities, further exacerbating the lack of digital skills and competences in students. To address this problem, the goal is to promote teamwork, planning, self-regulation, and the development of cognitive skills in students. The research approach used is qualitative, and an educational action research design will be followed. The study population comprises approximately 1637 students from San José Educational Institution, with the sample consisting of 9th-grade students in the Technology and Informatics area. The aim is to obtain an in-depth understanding of students' experiences and perceptions, as well as their active participation in the process of constructing infographic presentations.

    Práctica pedagógica de un docente vital de ciencias naturales desde el enfoque pedagógico crítico inclusivo de la suvidagogía EPCIS
    (2023-02-10) Alvarez Ruiz, Leidys Marcela; Agudelo Arteaga, Karen Patricia; González – Arizmendi, Samuel
    The systematization of the pedagogical practice of teachers is a key and important point that they should perform since it allows them to make visible the understanding, reflection and development that they approach from the social relations that happen around their academic and intellectual processes. Even so, despite all the importance of this process, it is not a habit or a frequent occurrence and that is why today few teachers write and reflect on the experiences they witness daily in their educational environment. Because of this, this proposal arises with the intention that teachers can organize and structure their practice and as main objective to systematize the pedagogical practice of a vital teacher of natural sciences of the Juan XXIII Educational Institution at La Esperanza from the inclusive critical pedagogical approach of the Epcis suvidagogy, where initially the elements of didactic strategy of this approach were identified, then the didactic strategy TAC (Conceptual Open Text) was applied and subsequently it was analyzed if the applied strategy is a fundamental tool to systematize the pedagogical practice of the teacher. The methodology was inclined under a constructivist paradigm, with a qualitative approach and the techniques used for data collection were the semi-structured interview, participant observation and the route to decant the information for systematization purposes provided by the suvidagogical approach. Finally, it was possible to systematize the pedagogical practice through the construction of the TAC (Conceptual Open Text) which allowed the teacher to reflect on his life history, the construction of new knowledge, to gather lessons that will allow him to enrich his practice and to encourage him to continue systematizing his teaching practice
