Introduction: This article is the product of a project developed by UNIMINUTO in the nineth grade of the Educational Institution Simón Bolivar in “La Nohora” neighbourhood of the Villavicencio - Colombia, this project was executed during 2017 and 2018. Problem: The problem is the low academic performance of students in mathematics, in addition to multiple possible adverse situations they face as a vulnerable population. Objective: The objective is to have a positive impact on the academic performance of the students. Methodology: In the strategy development, STEM education was used to support the learning of math through six sessions were carried out your own classroom. The students solved challenges by programming robots. Results: Complete each challenge had an important attitudinal impact on the students, the joy and satisfaction of them were an unexpected result. A previous knowledge test was carried out at beginning and at the end of the sessions a formative test was applied too. Afterwards, the results of both tests were compared to evidence improvements in the students' mathematical skills. Conclusions: It was possible to provide the target population with an alternative to understand issues mistakenly considered difficult and to propose important playful and didactic moments in cognitive development. Originality: This article shows an educational innovation that the team of researchers will continue to apply. through new projects that allow financing the purchase of equipment and the logistics of the workshops. Limitations: Lack of strategic alliances that allow financing more meetings with students and the acquisition of more robots.
Introduction: This article is the product of the research "Monitoring and Characterization of air quality in the downtown area of Villavicencio", carried out from 2018 to 2020 in Villavicencio - Colombia. Problem: Air quality directly impacts the health of the people who breathe it. Currently Villavicencio does not have enough monitoring stations, nor are there strategies to improve air quality. Objective: The main objective is to collect and analyse atmospheric and air quality information, to determinate the relationship between atmospheric variables and particulate matter. Methodology: Quantitative and experimental research in stages, a number of samples to be taken were defined and a statistical treatment was carried out. Different instruments were used to collect the variables. Results: The linear model between particulate material and atmospheric variables was obtained. The correlation index of particulate material with atmospheric variables was determined. The results were compared with regulations in Colombia and other countries. Conclusion: The results are within the limit allowed by national regulations. Linear models of the relationship between environmental variables and particulate matter were obtained. Originality: There are few studies related to air quality in the region. With the results, improvement actions can be proposed to local administrations to mitigate the impact on air quality in Villavicencio. Limitations: Sample collection time was limited, the availability of equipment in the institution where the research work originated also affected the scope of the work carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
