Categorías y prácticas implicadas con el pensamiento computacional para la mejora de las habilidades en la resolución de problemas matemáticos en secundaria
Get PDFThis reflection article shows how computational thinking comprises a set of skills required by today\u27s human capital, linked to a need regarding economic and labor demand in the era of the fourth industrial revolution. In addition, the educational deficiencies in the secondary grades, regarding the training of mathematics and computation, make it necessary to review the categories and practices that can be used in the process of training these skills in secondary school and innovate in the development of these skills. Therefore, from the literature review, three relevant categories associated with computational processes were found, which impact education in mathematical problem-solving skills in secondary school: algorithm programming, problem solving and modeling, through which the skills of computational thinking, problem decomposition, abstraction and algorithm design are developed. Unlike the Pólya method, which has been implemented in many studies to solve mathematical problems by carrying out steps such as: understanding the problem, establishing a plan, executing the plan and reviewing the process to ensure that no mistakes were made, computational thinking allows solving the problem and representing it through codes with mathematical algorithms, with various didactic tools. In this way, computational thinking currently acquires great importance to promote the development of the necessary competencies in the 21st century. The above shows lines of possibilities in new research that seek to develop pedagogical practices for the resolution of problems related to mathematics in secondary school; some of them include coding skills, use of blocks and graphics. This facilitates the internalization of knowledge that guarantees the progressive advancement of students in their mathematical and computational skills and their integral formation.En este artículo de reflexión se evidencia como el pensamiento computacional comprende un conjunto de habilidades que requiere el capital humano actual, vinculado a una necesidad respecto a la demanda económica y laboral en la era de la cuarta revolución industrial. Además, las carencias educativas en los grados de secundaria, en cuanto a la formación de las matemáticas y la computación, hacen necesario revisar las categorías y prácticas que se pueden utilizar en el proceso de formación de estas habilidades en la escuela secundaria e innovar en el desarrollo de estas. Por lo tanto, a partir de la revisión de la literatura, se encontraron tres categorías relevantes asociadas a los procesos computacionales, que impactan la educación en habilidades matemáticas de resolución de problemas en secundaria: la programación de algoritmos, la resolución de problemas y la modelación, a través de las cuales se desarrollan las habilidades de pensamiento computacional, descomposición del problema, abstracción y diseño de algoritmo. A diferencia del método Pólya que se ha implementado en muchos estudios para resolver problemas matemáticos llevando a cabo pasos como: comprender el problema, establecer un plan, ejecutar el plan y revisar el proceso realizado con el fin de asegurar que no se cometió algún error, el pensamiento computacional permite resolver el problema y representarlo a través de códigos con algoritmos matemáticos, con diversas herramientas didácticas. De esta forma, el pensamiento computacional adquiere en la actualidad una gran importancia para promover el desarrollo de las competencias necesarias en el siglo XXI. Lo anterior muestra líneas de posibilidades en nuevas investigaciones que buscan desarrollar prácticas pedagógicas para la resolución de problemas vinculados con la matemática en la secundaria; algunas de ellas incluyen habilidades de codificación, uso de bloques y gráficos. Esto facilita la interiorización de conocimientos que garantizan el avance progresivo de los estudiantes en sus habilidades matemáticas y computacionales y su formación integral.

A Review of Soil Improvement in Problematic Black Cotton Soil by Using Dry Kota Stone Slurry and Fly Ash
Get PDFBlack Cotton Soil (BCS) is particularly rapid-expanding and swelling when it meets water. This trait of soil results in extremely low soil strength and other attributes. Soil stabilization by various stabilizers is required to enhance its characteristics. Stabilization is a technique used to improve the soil\u27s structural integrity. Soil stabilization raises the subgrade\u27s load-bearing capacity, allowing it to better support the pavement and foundation. It is accomplished by increasing the soil\u27s shear strength and regulating its shrink-swell qualities. Expansive soils could have their engineering qualities enhanced via several different means. The problematic soils are either excavated and replaced with excellent, higher-quality material or treated with an additive. This paper analyzes soil improvement in problematic BCS using dry Kota Stone Slurry (KSS) and Fly Ash (FA). In thermal power plants, FA is produced as a byproduct of burning coal. It\u27s made up of dust and ash that are swept up in the exhaust when fuel is burned. The findings highlight its potential to address soil-related issues, enhance agricultural productivity, and contribute to sustainable land utilization practices

Covid-19 y exportaciones peruanas de espárrago fresco o refrigerado hacia Estados Unidos de América, periodo 2020 – 2021
Get PDFThe condition of the coronavirus has had a significant impact on the socio-economic sectors and on international trade. However, there are few studies that have supported that certain export products are not related to the coronavirus condition. The aim was to determine the relationship between Covid and Peruvian exports of fresh or refrigerated asparagus to the U.S., 2020-2021. A non-experimental-transectional design was used, with a quantitative approach, of correlational scope. The paper used the documentary analysis technique, applied to the population made up of Peruvian exports of fresh or refrigerated asparagus, with tariff subheading 0709.20.00.00, to the United States, 2020-2021. Through the statistical analysis exposed in the Results, it was indicated that all the hypotheses were rejected. Thus, it was seen that the relationship between Covid-19 and Peruvian exports of fresh or refrigerated asparagus to the United States were weak or non-existent. This means that the Covid-19 variable in its social, economic and health dimensions in the Peruvian State was not related to Peruvian asparagus exports to the US. It should be noted that there may be other factors such as conditions climate, changes in demand, competition, economic factors, logistics, transportation, etc., which could be related and can be investigated in the future.La afección del coronavirus ha tenido un impacto significativo en los sectores socio-económicos y en el comercio internacional. Sin embargo, existen escasos estudios que han sustentado que ciertos productos de exportación no se relacionan con la afección del coronavirus. Por tal, el objetivo recayó en la determinación de la relación entre la covid y las exportaciones en Perú del espárrago ya sea refrigerado o fresco con dirección a Estados Unidos, 2020-2021. Se tuvo un diseño no experimental-transeccional, cuantitativo y correlacional. Para el levantamiento de datos se empleó la técnica de análisis documental, aplicada a la población constituida por las exportaciones peruanas de espárrago fresco o refrigerado, con subpartida arancelaria 0709.20.00.00, hacia Estados Unidos, 2020-2021. A través del análisis estadístico expuesto en los resultados, se indicó que todas las hipótesis fueron rechazadas. Así, se vio que la relación entre variables eran débiles o nulas. Así, la variable de Covid–19 en sus dimensiones a nivel social, económico y de salud en el Estado peruano no tuvieron relación con las exportaciones peruanas de espárrago hacia EE.UU. En tanto, pueden existir otros factores como las condiciones climáticas, cambios en la demanda, competencia, factores económicos, logística, transporte, etc., que podrían relacionarse y puede investigarse a futuro
