Aprendizaje de los números complejos usando diferentes sistemas de cálculo simbólico y un sistema de evaluación en línea en formación inicial de profesores

Abstract

En este artículo se estudió el trabajo matemático personal de 15 profesores en formación inicial, en primer año de una universidad pública en Chile, a partir de dos tareas sobre números complejos. Estas tareas se plantearon en un CAA (Moodlle - Wiris) y se propuso resolverlas utilizando distintos CAS, como GeoGebra, Symbolab, Photomath y Wolfram Alpha entre otros. Se observaron dificultades y potencialidades en el trabajo matemático de los estudiantes. En las dificultades, se observó que los estudiantes tenían problemas para interpretar la información de los CAS y del feedback del CAA debido a que los conocimientos matemáticos previos no eran lo suficientemente solidos para hacerlo. En las potencialidades, se observó que distintas características de la tarea, junto con la articulación de dos o más artefactos permitió a los estudiantes darle significado a los objetos matemáticos involucrados. In this article we studied the personal mathematical work of 15 teachers in initial training, in the first year of a public university in Chile, based on two tasks on complex numbers. These tasks were presented in a CAA (Moodlle - Wiris) and it was proposed to solve them using different CAS, such as GeoGebra, Symbolab, Photomath and Wolfram Alpha, among others. Difficulties and potentialities were observed in the mathematical work of the students. In the difficulties, it was observed that the students had problems interpreting the information from the CAS and the AAC feedback because their previous mathematical knowledge was not solid enough to do so. In the potentialities, it was observed that different characteristics of the task, together with the articulation of two or more artifacts allowed students to give meaning to the mathematical objects involved.

Graduate Mathematics in the Age of AI: Forming Mathematicians for Original, Independent, and Responsible Inquiry

Artificial intelligence can increasingly produce plausible, sophisticated mathematical material faster than a developing graduate student can understand or verify it. A sophisticated result or paper draft therefore becomes weaker evidence of the student's own mathematical development. This creates a formation gap between output and personal capacity, and a trust gap between a convincing argument and warranted acceptance. The formation gap can persist even when the student understands the output: understanding a supplied argument does not by itself establish the capacity to initiate and direct inquiry. These gaps are not the whole story. AI can also help students explore examples, compare approaches, enter unfamiliar areas, and undertake ambitious research. The task is to design an apprenticeship that realizes these possibilities while developing substantive mathematical command. The central purpose of a mathematics PhD is to form mathematicians capable of original, independent, and responsible inquiry, including inquiry conducted with AI. This document develops that objective through four connected capacities: competence, judgment, independence, and responsibility. It distinguishes a work's contribution to mathematics from the evidence it provides of a student's formation; explains how a known answer can initiate rather than end creative inquiry; and proposes changes in learning activities, assessment, doctoral originality, advising, and institutional support. Purposeful independent work and ambitious AI-assisted research are complementary parts of the model. Its recommendations include proportionate contribution statements, recognition of advising costs, and staged pilots evaluating both mathematical ability and effective human--AI collaboration. The aim is not to preserve an inherited sequence of training, but to improve mathematical formation as mathematical practice changes.
