Didactic Engineering as a research method in physics teaching
...
Avendaño Castro, William Rodrigo | 2021-08-26

Several mathematical concepts have application in physics; this paper reports the results of a pedagogical investigation based on the methodology known as didactic engineering, which has been proposed with the aim of improving the skills exhibited by a group of eleventh grade students from a private institution in the interpretation of kinematic graphs. The concept of the slope of the straight line and how this mathematical concept can represent velocity or acceleration according to the variables considered in the kinematics graph provided was enhanced in the pedagogical intervention. This methodology offers a process of internal validation, after comparing the results obtained in a knowledge test at two different points in time (pre-test and post-test). The results allowed us to identify improvements in all students in terms of basic kinematics graph interpretation skills, and a group of students stood out by advancing in more complex reasoning and interpretation processes. These results contribute to the improvement of the pedagogical practices of Physics teachers at secondary and middle school levels, making them more competent when they enter higher education.

Imaginaries Of The Venezuelan Migrant From The Narratives Of A Border Community In Cúcuta, Colombia
...
Urbina Cárdenas, Jesús Ernesto | 2022-11-09

This text addresses the phenomenon of migration of the Venezuelan population to Colombia from the narratives of inhabitants of the border area of the Corregimiento de la Parada, located in the city of Cúcuta. Through these narratives the researchers show the atavistic imaginaries about the Venezuelan migrant through fivecategories: "the borders", "friend/enemy", "good/bad", "scapegoat", "an eye for an eye, a tooth for a tooth". An interpretative methodology is used, taking symbolic interactionism as a reference, insofar as it allows us to understand the process of creation and assignment of meanings by the residents of this area. The results show violence as a method to justify xenophobic attitudes against Venezuelan migrants.

Processes Of Educational Inclusion In Times Of Crisis
...
Vergara Fregoso, Martha | 2022-11-09

The pandemic marked society and, therefore, educational institutions, since preventive measures revealed large gaps and differences, and led to rethink the role of the school today, to rethink its constitution and redirect its actions towards a renewed entity, with new positions, new approaches and commitments, in order to respond to current needs and, even more so, to serve students with disabilities. This paper represents a research advance in which an analysis is made of the perspective, policies and strategies that the University of Guadalajara implements to guarantee inclusive education, and some of the effects generated in higher education students as a result of the COVID-19 pandemic; in particular, emphasis is placed on the effects that the situation has had on students with disabilities. For this research, some interviews were conducted with blind students from the same institution, in order to learn about their experiences during the health emergency.

Mathematical Modelling As A Tool To Understand Everyday Situations
...
Prada Núñez, Raúl | 2022-11-09

This research reports the effects derived from the application of mathematical modelling in classroom work within the development of mathematics classes, which allowed the resignification of the concept of linear function, making use of various semiotic registers of representation applied to a wide range of everyday situations. The fieldwork was based on the application of a didactic sequence to two groups of ninth grade students from a public educational institution located in the capital city of northeastern Colombia. The students were expected to build a mathematical model that would fit the data provided framed in the situations in context in order to contribute to the re-signification of mathematical knowledge. The results show that the practice of modelling favours the motivation of students in relation to mathematical knowledge, giving it meaning and significance when confronted with real situations.

Formative Meaning Of Teaching Practice
...
Freire Tigreros, María Eufemia | 2022-11-09

The perception that four teachers and one hundred students have of their teaching practices with theoretical support was explored, which served as a basis for discussion, of the incidence of teacher training on the educational task, from a qualitative research, inductive method, descriptive-interpretative approach. To address subjective aspects about before, during and afterthe practice, a non-participant observation guide and a student questionnaire were used as instruments. The results allowed recovering the contributions in two constructs: the theoretical meaning and the formative meaning. Here we present the analysis of the formative meaning that contemplates the subcategories of New Forms of Pedagogical Relationship (NFRP) articulated to critical dialogicity and Collaborative Work (CT) and derived from it, the importance of enhancing the formative nature of research.

Bayona Sanabria, Tatiana Torcoroma | 2022-11-09

This research article shows a broad analysis of the situation of migrants in the city of Cúcuta - Norte de Santander (Colombia) and the representations that the receiving citizens have in this border context. The methodological approach of this study was framed from the qualitative-hermeneutic paradigm where the life story was used as a basis for collecting information. The results of the research show that the discourses of the subjects under study legitimise violent actions towards the Venezuelan migrant population. Furthermore, it shows that in the border municipalities, residents naturalise the current situation, to the extent that it seems that the events that occur in this border context are isolated from the reality of those who do not migrate, describing them as "something normal".

Education And Prevention: Strategies To Prevent Adolescent Suicide
...
Gómez, Guillermo | 2023-05-01

Gatekeepers Training (GKT) is one of the most widely used and disseminated programs worldwide to train personnel in suicide prevention. The purpose of the program is to acquire the necessary skills and competencies to detect psychoemotional and mental health problems that could lead to self-destructive behaviors. In this research work, the level of risk related to suicide was evaluated by means of the ISO-30 psychometric test in high school students, then the effectiveness of a gatekeeper training program applied in the Tepatitlan Regional Preparatory School (TRPS) andsome of its modules was evaluated. The results of the ISO-30 psychometry showed that 64.5% of the students evaluated have a high-riskfactor for suicide related to the inability to cope with emotions. In addition to the above, a statistically significant difference was found (Mann-Whitney U Statistics = 4322.000; p0.001) in the level of competence of the participants in relation to a pre-training evaluation.It is important to note that the effect of the difference found is strong (Rosenthal’sr=0.67) so it is concluded that the GKT drastically improved the skills and competencies of the participants.

...
Prada Nuñez, Raul | 2022-10-22

This research reports the findings derived from the identification of the difficulties exhibited by a group of 76 students from different grades of basic secondary education in a private educational institution with an emphasis on science education. The students were given a questionnaire presenting five situations based on the Position-Time graph associated with uniform rectilinear motion of particles. The research approach is of a quantitative nature at a descriptive level with a field design, since it was the students who filled in the instrument. It is highlighted as a finding in the opinion of the students that the subject has been seen in class, but due to the teacher’s methodology it is not fully understood by them. The results show that the students have a long list of difficulties mainly due to the lack of articulation of mathematical concepts in physical contexts, a situation that prevents them from analyzing the proposed statements, reasoning about the approaches, and improving in the process of searching for alternative solutions with clear arguments.

Inquiry-based learning. Beliefs of trainee teachers in a physics course
...
Pabon Galan, Carlos Antonio | 2022

The teaching of physics should be supported by practical or laboratory activities that seek to develop the scientific competencies of the students who study physics, so it is necessary to propose innovative strategies, such as research-based learning, in which students answer research questions through the analysis of data, which increases the interaction between the student and the physical concepts under investigation. Therefore, the objective of the study was to analyze the beliefs of teachers in natural science training at a public university in Colombia who take the subject of physics on research-based learning, to provide information on how to guide the use of innovative strategies. The study responds to a type of quantitative research with a descriptive approach and was based on a field design. On the other hand, the results reflect slightly positive beliefs of students in initial teacher training who study physics about researchbased learning as an innovative strategy, although it is recommended to expand the sample to generalize. Finally, the analysis reveals as a conclusion that the implementation of innovative methodologies such as inquiry-based learning for science teaching, especially physics, should be promoted and supported more effectively to foster motivation, skills development, and conceptual understanding. of the scientific contents.

Hernandez Vergel, Viviana Karina | 2022-05-24

El virus Zika se transmite por la picadura de mosquitos infectados, pero también puede ocurrir a través de una infección intrauterina antes del parto, y el virus pasa al feto. Objetivo: describir el nivel de afectación en destrezas de ejecución y edad madurativa de niños del programa Valientes del Futuro con la infección neonatal por virus Zika. Materiales y Métodos: La investigación se enmarca con enfoque cuantitativo de tipo correlacional apoyada con una investigación de campo y diseño no experimental, con una muestra de 15 infantes de 3, 4 y 5 años. La técnica de recolección utilizada fue la Escala Abreviada. Resultados: En cuanto a las áreas evaluadas con respecto a la edad madurativa se encontró que la ponderación de la destreza motora y praxis halló un coeficiente de correlación de 0,601 (moderada) y en la muestra de las destrezas de ejecución de los niños de 3 años con zika gestacional se obtuvo una correlación de 0,853 (fuerte). Discusión: la infección por virus zika en niños y niñas, adquirida durante la gestación, limita fuertemente las destrezas de ejecución propias de la edad madurativa en esta población. Conclusiones: Existe correlación entre los infantes con zika gestacional y la afectación fuerte en las acciones o comportamientos que un paciente tenga para moverse e interactuar físicamente con actividades, objetos y por ende realizar una actividad motora aprendida.

...
Ramírez Carvajal, Luis Eduardo | 2022-01-05

A computational tool for learning electrostatic physics is presented through the development of a disruptive methodology. The tool allows the analysis of case studies based on Coulomb’s law, Gauss’s law, Poisson’s equation, and Laplace’s equation with boundary value. The tool was tested using reference exercises for each case study, making use of quantitative and qualitative comparative analysis between the traditional mathematical development and the computational tool. Errors were measured using Likert scale. The quantitative results showed errors of less than 1.8% in all the cases studied, concluding that the tool is effective. The qualitative results showed that the methodology allows a better development of the electrostatics learning process, dynamizing the study of complex topics such as electromagnetic physics theories through interactivity and technological resources, in addition to having a theoretical module developed using agile methodologies that provide dynamism and an intuitive environment to the interface.

Topological stereotomic structure with the use of palm rachis applying material physics to architectural design
...
Cadena González, I M | 2021-06-04

The use of ancestral construction techniques in wood has evolved throughout history, but consequently many species have been disappearing after indiscriminate logging; but the use of renewable materials is what is needed in the present and in the future after the global pollution and the ecological footprint of materials such as iron or concrete, so it is necessary to glimpse new building materials from a renewable approach. To this end, this research focuses on the application of physicochemistry and physics of materials to establish the feasibility of using Attalca Butyracea palm rachis as a sustainable material with a novel application in the field of architecture. For this purpose, a methodology of morphological configuration is applied that appropriates the identification of specific physical properties together with notions of geometry and topology applying the concept of topological stereotomic configuration from the operational tools and morphological actions of the Lucas Períes fold, resulting in a proposal for a topological stereotomic structure applied to the architectural design of buildings in the municipality of Pelaya, Colombia.

Physical-mathematical model to determine the structural efficiency of sections shaped as ellipses and parallelograms when used in reinforced concrete columns
...
MARQUEZ-PEÑARANDA, JORGE FERNANDO | 2021-06-09

Current practice of structural design of reinforced concrete columns uses mainly rectangular and circular sections. Among other reasons, this preference is linked to its ease of construction and spatial efficiency, and the historical inertia of civil works processes. Nowadays, modern design and construction techniques make possible to study the structural beahviour of sections distinctively shaped. If typical sections are extended from circular to elliptical and from rectangular to parallelogram shaped, it is possible to compute mathematical and physical parameters needed for the structural analysis. This work presents a physical–mathematical model to determine the structural efficiency in terms of relative strength and stiffness of sections shaped as ellipses and parallelograms when used in reinforced concrete columns. To solve the model, a Matlab® code for drawing the column interaction diagram of each studied section was written. Each diagram describes, in terms of mechanical physics, the relation between the uniaxial bending and the compression load that defines safety conditions as a mathematical limiting curve. The governing equation has the form P(m,g)=f(M(m,g) in which P describes the axial load strength function, M the bending moment strength function, m the material properties, and g the geometrical characteristics function. Structural efficiency has been expressed as the relative behaviour of each section with respect to comparable rectangular sections. To obtain the results of the model, a Matlab® code was written.
