The University Academic Accompaniment Plan (AAP) was aimed at freshmen students whose ICFES test results were below the national average. The study's approach was quantitative, where two semesters were analyzed 2020-I and 2020-II consisting in 189 and 146 surveyed students, respectively. The SPSS version 22 statistical program and the Academic Valuation Software were used, and results were parameterized by two tests a pre-test and post-test. Mann Whitney's U-test was applied to contrast the two semesters, to analyze the effectiveness of each semester, the T-Student test was used for related samples and the Wilcoxon test in cases where there was no normality;finally, an exploratory factorial and reliability analysis was carried out through the Cronbach’s alpha statistic to determine how related the questionnaire questions were in terms of quality of service and methodologies. According to the results of this study, it was found that the AAP in the two semesters managed to be statistically effective and the methodologies implemented for the approach and development of skills through ICT in both semesters resulted to be statistically significative, reliable, and adequate. These findings lead to the conclusion that the AAP in mathematics and critical reading was effective for skills development, through the working process in remote access during the COVID-19 pandemic. © 2021, Springer Nature Switzerland AG.

Estos retos implican cambios significativos en los modelos de ensenanza y la incorporacion de las tecnologias de la informacion y la comunicacion. En el mundo actual, donde se ha asumido la necesidad de la formacion a lo largo de la vida y las tecnologias han pasado a tener un papel relevante, la educacion esta abocada a replantearse sus objetivos en la formacion de un profesional en educacion, con habilidades practicas, conocimientos, motivacion, valores eticos, actitudes, emociones y a la incorporacion del concepto de competencia digital para lograr una accion eficaz ante las demandas crecientes de las sociedades y las nuevas pautas socioculturales. Los cambios exigidos en torno a la formacion profesional vienen...

En ese sentido, la Universidad de la Costa en Colombia, ha disenado el Plan de Acompanamiento Academico con el proposito de mejorar las competencias de los estudiantes, es por ello, que el objetivo del presente articulo consiste en analizar la incidencia del Plan de Acompanamiento Academico sobre las competencias de lectura critica y matematicas, de los alumnos del primer semestre en dicha universidad. El abordaje metodologico fue empirico-analitico, cuantitativo, con diseno cuasi experimental pretest y postest. La muestra fue conformada por 171 estudiantes de pregrado. Los resultados evidencian la existencia de diferencias significativas al 95% (Wilcoxon W, p: .000) entre (pretest y postest), con un incremento en las competencias tanto de lectura critica como de matematicas, obteniendose ...
