Aprender a aprender se convierte en una competencia clave en la sociedad del conocimiento. El objetivo de este estudio es analizar las estrategias de aprendizaje de los alumnos de grado de la Pontificia Universidad Católica del Ecuador, Sede Esmeraldas, y su relación con las variables género, rendimiento académico y nivel de estudios. Para ello se realizó un estudio descriptivo y correlacional. Se aplicó la escala ACRA de Román y Gallego a una muestra de 849 alumnos. Los resultados evidencian que el nivel de práctica de las estrategias es medio bajo. En cuanto al análisis correlacional, no existe relación estadísticamente significativa con el nivel de estudio, mientras que con el género y con el promedio de calificaciones se observan relaciones estadísticas débiles.
This paper presents the theoretical elements that support the calculation of the prime number counting function, π(x), based on properties of the sequences (6n-1) and (6n+1), n ≥ 1. As a result, Sufficient primality criteria are exposed for the terms of both sequences that support a deterministic computational algorithm that reduces the number of operations in calculating the function π(x) by exonerating all multiples of 3 from the analysis. In analyzing the primality of a particular term, the divisions by factor 3 are excluded. Such an algorithm can be applied to the search for prime numbers in each sequence separately, a possibility that allows approximately half the time of number search in practical applications.
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.
