Teacher-researchers Exploring Design-based Research to Develop Learning Designs in Higher Education Language Teaching

2012

Due to constant changes and developments of the 21st century societies and working life, the environments in which learning takes place have changed. Novel ways to research learning in those environments and to explore how learning could be supported with the learning design are needed in order to bring about changes in teaching practices. One of those ways could be design-based research (DBR), an iterative, interventionist and flexible research strategy, which would allow cycles of developing theory of learning as well as implementing design principles in practice. This article describes how we, as teacher-researchers, have adopted a design-based research approach in two separate studies i…

Preparaciones de base líquida vs. citología convencional: adecuación de las muestras y coincidencia de diagnóstico en lesiones orales

2005

Objetivo: Comparar la efectividad de la muestra y la coincidencia de diagnostico entre preparaciones de base liquida y frotis convencionales en lesiones orales, y probar la viabilidad de la prueba inmuno-citoquimica en preparaciones de base liquida de lesiones de carcinoma oral. Material y Metodos: Se obtuvieron muestras de 44 pacientes. Primeramente se prepararon frotis convencionales, usando un dispositivo cytobrush. A continuacion se sumergio el cepillo que contenia el material residual en un liquido conservante. La muestra en el mismo fue procesada de acuerdo con las indicaciones del fabricante (AutoCyte, Inc. Elon College, North Carolina, USA). Se tineron preparaciones de ambas tecnica…

Enriching primary student teachers’ conceptions about science teaching: Towards dialogic inquirybased teaching

2012

Inquiry-based teaching has been at the heart of science education since it was first outlined in national standards over a decade ago. The general idea behind the inquiry guidelines is that pupils would adopt ways of conducting science, in addition to conceptually learning, thus attaining also the epistemological dimension of science. Although curricula are based on these ideas of inquiry, all too often authentic inquiry is hindered by overly authoritative approaches and teacher directions. To avoid this, the communicational ways in which teachers can encourage pupil reasoning during different phases of inquiry should be explicitly addressed. This paper addresses this gap by introducing a d…

Dialogicality in making sense of online collaborative interaction : a conceptual perspective

2021

In higher education, learning activities increasingly take place in online collaborative groups. In this conceptual paper, we explore online collaborative interaction from the perspective of dialogicality. We aim to reconceptualize the notion of “productive interaction” and the typical focus of its research by turning attention to the dialogic features of collaborative interaction, especially the notions of alterity, dialogic attitude, and dialogic orientation. In relation to this, we offer a contextual perspective on collaborative interaction. Relying on data from an online university course, we conceptually analyze specified components of dialogicality. This article illustrates and explor…

The Supremacy of the Constructivist Approach in the Field of Physics Education: Myths and Real Challenges

2012

We intend, first of all, to show that the supposed 'supremacy of the constructivist epistemology' in the field of physics teaching is just a myth that hides the actual supremacy of the ineffective transmission/reception model. We then centre our analyses and proposals on the real challenges to improve students' learning and attitudes. Résumé Nous essayons de montrer que la prétendue « suprématie de l'épistémologie constructiviste » dans le domaine de la didactique de la physique n'est qu'un mythe, qui cache la suprématie effective du modèle inefficace de la transmission/réception. Nous centrons ensuite nos analyses et propositions sur les défis réels pour améliorer l'apprentissage et les at…

Testing the Sobolev property with a single test plan

2020

We prove that in a vast class of metric measure spaces (namely, those whose associated Sobolev space is separable) the following property holds: a single test plan can be used to recover the minimal weak upper gradient of any Sobolev function. This means that, in order to identify which are the exceptional curves in the weak upper gradient inequality, it suffices to consider the negligible sets of a suitable Borel measure on curves, rather than the ones of the $p$-modulus. Moreover, on $\sf RCD$ spaces we can improve our result, showing that the test plan can be also chosen to be concentrated on an equi-Lipschitz family of curves.
