“…Durante la última década (2010-2020) LACLO ha sido un dinamizador de la construcción de redes científicas en la temática de la EA en la región. Al respecto [29] presentan un análisis general de algunas de las principales iniciativas, resultados e impactos de las redes de colaboración científica articuladas por LACLO. De nueve grandes proyectos y redes analizados, seis se orientaron a la investigación, desarrollo e innovación vinculadas a la EA y los REA.…”

There is great potential in the use of open educational resources (OER). This article presents the GlobalNetwork of Graduates of REA (GO-GN) a network that includes PhD candidates from around the world, whose research projects include a focus on Open Education (OE), and the potential for collaboration with the Latin American Community of Learning Objects (LACLO). This collaboration may help to raise the profile of OE research in Latin America, offer support to those conducting doctoral research in this area, promote equity and inclusion in the field of OE research, and promote open science at all levels of the research process. In this sense, a series of options are offered, such as participation in conferences and webinars, joint processes that can potentially co-development of research publications and projects, and the recognition and expansion of the impact of the achievements of its members and alumni at a global level.

Early Prediction of At-Risk Students in Secondary Education: A Countrywide K-12 Learning Analytics Initiative in Uruguay

et al. 2022

This paper describes a nationwide learning analytics initiative in Uruguay focused on the future implementation of governmental policies to mitigate student retention and dropouts in secondary education. For this, data from a total of 258,440 students were used to generate automated models to predict students at risk of failure or dropping out. Data were collected from primary and secondary education from different sources and for the period between 2015 and 2020. Such data contains demographic information about the students and their trajectories from the first grade of primary school to the second grade of secondary school (e.g., student assessments in different subjects over the years, the amount of absences, participation in social welfare programs, and the zone of the school, among other factors). Predictive models using the random forest algorithm were trained, and their performances were evaluated with F1-Macro and AUROC measures. The models were planned to be applied in different periods of the school year for the regular secondary school and for the technical secondary school ((before the beginning of the school year and after the first evaluation meeting for each grade). A total of eight predictive models were developed considering this temporal approach, and after an analysis of bias considering three protected attributes (gender, school zone, and social welfare program participation), seven of them were approved to be used for prediction. The models achieved outstanding performances according to the literature, with an AUROC higher than 0.90 and F1-Macro higher than 0.88. This paper describes in depth the characteristics of the data gathered, the specifics of data preprocessing, and the methodology followed for model generation and bias analysis, together with the architecture developed for the deployment of the predictive models. Among other findings, the results of the paper corroborate the importance given in the literature of using the previous performances of the students in order to predict their future performances.
