Teaching Probability for Conceptual Change La Enseñanza De La Probabilidad Por Cambio Conceptual

This work presents a theoretical proposal for a methodology for the teaching of probability theory. The theoretical proposal has a dual inspiration: (1) the epistemological approach of Lakatos (1978b) regarding the quasi-empirical nature of mathematical theories; (2) the perspective of conceptual change for the teaching-learning process, as formulated by Strike and Posner (1992). The scientific content taught and the didactic methods used in the classroom should, according to this proposal, respect and conform to this dual inspiration. We also present an evaluation of the methodology in a real context: six Spanish high school classes of students aged 14–15. The main purpose of the research was to answer this question: Is our didactic proposal more effective than traditional methodology? We operatively identify the concept of traditional teaching, and establish several indicators of effectiveness: the mastery of elementary probability calculations, the quality of intuitive reasoning in probability, and the conceptual and attitudinal change produced. We found significant differences on all indicators, except for attitudinal change, in favour of the group that followed our proposal.     

Language Acquisition Assisted by the Internet

Abstract

The authors focus on exploiting new methods of language acquisition with the help of the possibilities offered by the Internet. As a new option for computer‐assisted language learning, the Internet is considered to be a source for individual learning and problem oriented teaching in many other areas. Expanding knowledge in parallel in informatics and the English language is an asset. In addition to pointing out starting off sites for ESL teachers and introducing some interesting examples, some criteria of constructing language teaching WWW pages of our own are also listed.     

Ciencia en Nepantla: the journey of Nepantler@s in science learning and teaching

This paper presents a new approach to science education that takes a path through sociocultural theory and into the ideas of Gloria Anzaldúa. We apply Anzaldúan theory to science education by illustrating it in action through various examples which explore the multidimensionality of teaching science with Latin@ students in various contexts including dual language settings. We present what it is to journey through transformation using examples from educators at various levels of science within the world of teaching science with Latin@ students in the U.S. Our examples illustrate how Latin@ students cross many cultural borders in Spanish, English, Latin@ home culture, school culture, and the world of scientific dialogue and content, and in doing so, go through tensions and transformations between dominant and non-dominant worlds, which should be acknowledged and better understood through Anzaldúan theory. Fundamentally, we present a transformative notion of Latin@ science learning as “living on the bridges” of many dialogic and cultural practices, and having to negotiate these in-between spaces, or “nepantla” (Anzaldu´a and Keating in Interviews, Psychology Press, London, 2000), where Latin@ students must contend with the fragmented and sometimes painful struggle of living in racialized reality amidst the demands of a dominant culture, and where transformation and healing are possible through the path of conocimiento. We advocate for teachers to become science teacher nepantler@s, who guide their students through nepantla, and into a new mestiz@ consciousness of science education.     

Sighting horizons of teaching in higher education

This conceptual paper tackles the matter of teaching in higher education and proposes a concept of ‘horizons of teaching’. It firstly offers an overview of the considerable empirical literature around teaching—especially conceptions of teaching, approaches to teaching and teaching practices—and goes on to pose some philosophical and social theoretical considerations that open further the territory around teaching in university. Against this background, we propose the concept of ‘horizons of teaching’. Horizons of teaching provide a context in which it makes sense for teachers to give themselves to the teaching enterprise and to go on giving themselves to teaching. Horizons include diverse and intricate layers at both micro- and macro-levels that interact in a permanent and dynamic way; they involve persons and collectivities; and they concern structures and agency. The paper concludes by proposing that horizons of teaching configure and delineate curricula and the pedagogical relationship in a way that might contain a revolutionary potentiality in recasting teaching in higher education.
