Authentic-interactive activities to promote oral production on a virtual platform

Implementing learning or communicative strategies are not enough to develop oral production when learning English as a Foreign language; indeed, it is necessary to provide authentic activities that engage students in the act of speaking. The objective of this research is to know if the interactive activities operated in the Moodle platform promote oral production and identify the possible association between their scores from the instructional design and their speaking level from a standardized exam. For this, a longitudinal quantitative approach was carried out during spring 2020 in the Teaching English Bachelor at BUAP, having a sample of 20 subjects. The results demonstrated that the use of authentic-interactive activities improved the students’ speaking competence significantly. Furthermore, this study pretends to contribute with useful theoretical information for teachers and students who want to select appropriate tasks to improve this competence. It is essential to clarify that this is an innovative study since it promotes the use of activities and strategies mediated by technology asynchronously and synchronously, which are flexible and suitable for students’ needs in times of contingence.

Characterization of SARS-CoV-2 cases in Mexico using data mining

In this paper, it is realized an analysis of the data published by the Federal Government of Mexico on the cases related to the test for detecting the presence of the SARS-CoV-2 virus, that originates the COVID-19 disease. More than a million cases were analyzed, most of which were positive to the test. For this study, twenty-one significant variables were considered, included the result of the test and the cases of death, going through the different factors that complicate a person’s health such as diabetes, chronic obstructive pulmonary disease (COPD), asthma, hypertension, obesity and smoking, among others. At the beginning of the study, the preparation of the data was carried out so that they could be treated using data mining techniques, based on the CRISP-DM methodology for extraction of knowledge. Thus, with the help of this type of techniques, data models were generated to characterize the development of the COVID-19 disease in the national and local (by States) panorama. As an important part of the models, various rules or correlations were observed among the different variables, which could be used to predict, in part, the future development of the COVID-19 disease in Mexico and, consequently, to establish best practices that target to reduce its social impact.

Comparison of numerical methods in code as solvers for simulation of robotic systems

This research introduces the development of the implementation and comparison of algorithms of numeric methods which solve a system of ordinary differential equations, commonly known like solvers. These were applied to a robotic system with 4 grades of freedom in open loop based on the non-linear dynamic model in the joint space. The performance of the robotic system solution simulated on Matlab®/Simulink® with S-Function has been assumed to be the reference criterion to contrast the results that were get from codification of the solvers. Moreover, some inferences were set for each one of the algorythms, for instance, simulation time and computing cost. The analysis of the results lets account the implementation of the code of the numeric methods for simulation purposes, thus, it may aid for the optimization of simulation times and computing cost.
