Creativity is a growing demand in today's world. Education for creativity takes hierarchy, as well as the search for ways to evaluate its promotion. This paper presents partial results of a research project aimed at the study of the promotion of creative qualities in science education. The CREA test was used as an instrument to evaluate the creativity of students. The results allow us to propose limitations of this test as a tool for a global measure of creativity. The conventional analysis could measure one of the creative qualities: fluidity. The assessment of other creative qualities could benefit from a modified analysis. Some modifications like test time, could improve the measure of flexibility and elaboration. The applicability of the CREA test may not be accompanied by quality to the extent of creative potential.

El estudio de procesos biológicos en un laboratorio y con protocolos simplificados puede introducir o fortalecer errores conceptuales. Este es el caso del transporte de agua, cuando se enseña como ósmosis. El presente trabajo describe una experiencia que atiende dicha problemática. Introduce el concepto de transporte de agua diferenciándolo del de ósmosis, plantea dificultades en su enseñanza, señala conceptos inclusores erróneos frecuentes, fundamenta por qué protocolos de uso habitual fortalecen dichos conceptos erróneos y relata experiencias sustentadas en el Modelo de aprendizaje cognitivo consciente sustentable. Dichas experiencias proponen protocolos ampliados que contribuyen a la introducción de conceptos sostén relevantes, favoreciendo un aprendizaje sustentable del transporte de agua.
