The objective was to learn defined integrals using free software as a didactic resource, with students of the first semester of the Faculty of Mechanics at Escuela Superior Politécnica de Chimborazo, in the period September 2021 - March 2022. The research approach was quantitative, with an explanatory scope and a quasi-experimental design. A sample of 232 students was calculated and divided into two study groups: an experimental and a control group. In the first diagnostic stage, a survey was applied to the students in which they stated that the academic performance of the definite integral would improve with the use of technological tools. Students were also tested with an objective diagnostic test in which the homogeneity of the groups was verified through the F test for variances between two samples. Subsequently, by means of GeoGebra software, learning activities on definite integrals were designed and applied in the classes of the experimental group in stage 3, whereas the control group learned with the traditional methodology. For the validation of the experiment, an objective summative test was carried out, obtaining an average of 6,25 for the control group and 7,54 for the experimental group. The results were analyzed by use of the Z test, obtaining a Zc of 4,704. Thus, the null hypothesis was rejected, and the alternative hypothesis was accepted. It is concluded that the use of free software as a didactic resource affects the learning level of definite integrals in first semester students of the Faculty of Mechanics. 2023-07-23T00:00:00Z https://repositorioslatinoamericanos.uchile.cl/handle/2250/8267049 Análisis de los factores determinantes de la inclusión y profundización financiera y la concentración del sector bancario en el Ecuador, periodo 2010-2020. Financial inclusion has been a worrying factor for financial and banking institutions, due to the high proportion of people in the country who do not have products and services in this area, meaning that they are excluded from the formal financial system; therefore, they do not benefit from the innovations and progress offered by banks, regarding savings and management of financial operations. The objective of this paper was to analyze the determinants of financial inclusion and concentration in the banking sector in Ecuador, period 2010-2020; given the existence of a division of the financial market, on the one hand the banks that cover the cities, where there are urban sectors with greater ease and accessibility to financial services; and, on the other hand, the rural sectors that have great limitations and weaknesses that over time have increased marginality, persevering inequalities to financial services. The methodology used in the research is qualitative, which is characterized by the use of a flexible design to face the reality of the populations under study with any of its alternatives, where an attempt was made to integrate concepts from different social research orientation schemes. In conclusion, finance and innovation are indispensable elements of financial inclusion, since they facilitate accessibility and the request of financial products and services, without the need to necessarily go to the nearest bank offices or branches; thus, discarding the high rate of financial exclusion in regions and/or rural areas of the country, since they do not have nearby services to manage the opening of savings/current accounts or the request of financing. It is recommended to all financial and banking institutions, to have technological and digital elements that are adequate to the new demands in society, such as the possibility of performing operations from smartphones through virtual banking, so that limitations and deficiencies can be eliminated regarding access and application for financial products and services, which have kept users demanding procedures that people must necessarily perform through traditional and face-to-face channels. 2023-07-23T00:00:00Z https://repositorioslatinoamericanos.uchile.cl/handle/2250/8266784 Desarrollar una aplicación web para el registro de pedidos de computadores personalizados y preensamblados en la empresa informática Mega Sistemas. The vision of this work was to develop a web application for inventory management and sale of computer items, especially pre-assembled computers or with personalized settings, for the computer company Mega Sistemas. Within the execution plan, the SCRUM software development methodology was used, which allowed to organize optimally all the work in phases that were pertinently carried out. The application runs an architecture in N layers. The integrated management system for business “Odoo” was used, which was the base platform where the entire web application was designed. Such platform works with the Python programming language. Referring to Odoo database, it is operated by PostgreSQL. The entire work environment mentioned was set on a computer with the Ubuntu operating system and the PyCharm IDE. In turn, another approach of the project was to evaluate the availability offered by the application to its users when making a purchase. Referring to this availability as the capacity of the system to be active whenever you need it and to provide, through filters, an intuitive navigation, a form of virtual advice, which frees users from the need of having personal technicians to guide their purchase, except in special cases. All this was evaluated by means of a survey based on ISO 25010, on software quality models that contains the availability as a feature. Giving as a final result an acceptance percentage of 94.5% for the application, which indicates that it fulfills the expected purpose. It is recommended to incorporate new payment methods in future updates of the site, such as payments by credit cards. 2022-02-25T00:00:00Z https://repositorioslatinoamericanos.uchile.cl/handle/2250/8266939 Desarrollo de un sistema de recomendación de contenidos educativos basado en estilos de aprendizaje aplicado a la Escuela de Ingeniería en Sistemas. The objective of this work was to develop an educational content recommender system based on learning styles that allows managing and recommending content to students in order to improve their academic performance. Its development contemplated two studies, a preliminary study that established the preferences of content regarding learning styles, and another study to evaluate the academic performance of the students who utilized the system. As data collection techniques, we utilized the following: documentation review, learning style test of David Kolb, test to determine content preference and a structured evaluation with multiple choice questions. The population for the studies were software engineering students from the Escuela Superior Politécnica de Chimborazo, the sample for the first study were 128 students, and for the second study there were two groups of students named control group and experimental group, respectively to apply and compare their results when interacting with the system and its content. We developed the content recommender system with java language programming following the XP methodology and using tools and technologies such as: NetBeans IDE, javascript, Ajax, PrimeFaces and PostgreSQL. The results obtained related to content format preference in relation to learning style demonstrated that the convergent/assimilator groups prefer the video format, while the divergent/accommodator groups prefer the simulation format. The evaluation of academic performance determined that the experimental group obtained an average of 15.60/20, while the control group obtained 12.74/20. We applied the t-student test and we determined that there is a significant difference between the means of the data. We concluded that the use of the recommender system improved student performance by 14.3%. We suggest uploading content in various formats to have more options when making the recommendation. 2022-01-21T00:00:00Z
