Abstract
espanolSe construyo un instrumento de medicion altamente confiable, con validez de contenido y de criterio. Su contenido esta basado en las habilidades algebraicas que los estudiantes de ingenieria requieren para desempenarse favorablemente en un Curso de Calculo Diferencial en las carreras de ingenieria. En el diseno del instrumento participo un equipo de 10 profesores con al menos grado de maestria y experiencia docente en el area de calculo diferencial. El instrumento de medicion es de opcion multiple, criterial, de gran escala, esta integrado por 25 reactivos y su analisis de calidad se describe y se deriva de las respuestas emitidas durante los ciclos lectivos 2018-2 y 2019-1 por estudiantes de nuevo ingreso en la carrera de ingenieria. Los resultados muestran que los topicos que predicen el exito del alumno y cuentan con el mayor poder de discriminacion en el instrumento de medicion estan fuertemente relacionados con habilidades que los estudiantes adquieren desde la primaria y secundaria, como es el caso de las operaciones con fracciones y las leyes de los exponentes. Tambien se logro identificar que la mayor deficiencia en las habilidades algebraicas de los estudiantes pertenece al tema de la racionalizacion, division de polinomios, factorizacion de suma y diferencia de cubos. EnglishA highly reliable algebraic skill measurement instrument with content and approach validity was developed. Its content focusses on the algebraic skills engineering students require to successfully follow a Differential Calculus Course. A team of 10 teachers, each with minimum of a master’s degree and teaching experience in differential calculus, participated in the design of this instrument. The measurement instrument is a large-scale multiple-choice criteria test comprising 25 test items. Its quality is described and analysed on the basis of the answers given by engineering students during the first and second semesters of the 2018-2019 academic year. The results show that topics that can predict student success and have the greatest power of discrimination in the measurement instrument are strongly related to skills students acquire in primary and secondary education, such as operating with fractions and the laws of exponents. It was also found that the main shortcomings in the algebraic skills of students are rationalisation, division of polynomials, factoring sums, and difference of cubes.
期刊介绍:
The revista española de pedagogía (Spanish Journal of Pedagogy or rep) is one of the oldest journals in the world dealing with pedagogical research. During the several decades it has been published, the revista española de pedagogía has always maintained the highest standards of quality and it has gained international awards. The logo of the journal is a wheel, a symbol that wants to evoke several ideas: creativity and forward motion, the wisdom eye that enters into the knowledge of reality, the sun that radiates knowledge and makes ideas shine more clearly, as well as the globe, the sign of an education that is interested in the society where it belongs. This symbol, together with some other figures.
