El propósito de la investigación fue conocer las concepciones epistemológicas de la naturaleza de las ciencias, el conocimiento científico y el que hacer científico por parte de los maestros de ciencia del nivel secundario de la Región Educativa de Arecibo y su relación con el aprovechamiento académico de los estudiantes en la materia de ciencia.

In this expanded and revised edition of a fresh and original case-study textbook on environmental ethics, Christine Gudorf and James Huchingson continue to explore the line that separates the current state of the environment from what it should be in the future. Boundaries begins with a lucid overview of the field, highlighting the key developments and theories in the environmental movement. Specific cases offer a rich and diverse range of situations from around the globe, from saving the forests of Java and the use of pesticides in developing countries to restoring degraded ecosystems in Nebraska. With an emphasis on the concrete circumstances of particular localities, the studies continue to focus on the dilemmas and struggles of individuals and communities who face daunting decisions with serious consequences. This second edition features extensive updates and revisions, along with four new cases: one on water privatization, one on governmental efforts to mitigate global climate change, and two on the obstacles that teachers of environmental ethics encounter in the classroom. Boundaries also includes an appendix for teachers that describes how to use the cases in the classroom.

This book focuses on the talk of science classrooms and in particular on the ways in which the different kinds of interactions between teachers and students contribute to meaning making and learning. Central to the text is a new analytical framework for characterising the key features of the talk of school science classrooms. This framework is based on sociocultural principles and links the work of theorists such as Vygotsky and Bakhtin to the day-to-day interactions of contemporary science classrooms. *presents a framework, based on sociocultural theory, for analysing the language of teaching and learning interactions in science classrooms *provides detailed examples and illustrations of insights gained from applying the framework to real science lessons in Brazil and the UK. *demonstrates how these ways of thinking about classroom talk can be drawn upon to inform the professional development of science teachers. *offers an innovative research methodology, based on sociocultural theory, for analysing classroom talk. *expands upon the ways in which sociocultural theory has been systematically applied to analysing classroom contexts. This book offers a powerful set of tools for thinking and talking about the day-to-day practices of contemporary science classrooms. It contains messages of fundamental importance and insight for all of those who are interested in reflecting on the interactions of science teaching and learning, whether in the context of teaching, higher degree study, or research.

When children begin secondary school they already have knowledge and ideas about many aspects of the natural world from their experiences both in primary classes and outside school. These ideas, right or wrong, form the basis of all they subsequently learn. Research has shown that teaching is unlikely to be effective unless it takes into account the position from which the learner starts. Making Sense of Secondary Science provides a concise and accessible summary of the research that has been done internationally in this area. The research findings are arranged in three main sections: * life and living processes * materials and their properties * physical processes. Full bibliographies in each section allow interested readers to pursue the themes further. Much of this material has hitherto been available only in limited circulation specialist journals or in unpublished research. Its publication in this convenient form will be welcomed by all researchers in science education and by practicing science teachers continuing their professional development, who want to deepen their understanding of how their children think and learn.

This book documents and disseminates experiences from a wide range of universities, across the five continents, which showcase how the principles of sustainable development may be incorporated as part of university programmes, and present transformatory projects and programmes, showing how sustainability can be implemented across disciplines. Sustainability in a higher education context is a fast growing field. Thousands of universities across the world have signed declarations or have committed themselves to integrate the principles of sustainable development in their activities: teaching, research and extension, and many more will follow.

First published in 1994. Leading scholars in science education from eight countries on four continents and ex-pert practising science teachers (primary and secondary) wrote about the teaching and learning of particular science content or skills, and hence how different science content requires different sorts of teaching and learning. Having shared the papers, they then met to discuss them and subsequently revised them. The result is a coherent set of chapters that share valuable insights about the teaching and learning of science. Some chapters consider the detail of specific topics (e.g. floating and sinking, soil and chemical change), some describe innovative procedures, others provide powerful theory. Together they provide a comprehensive analysis of constructivist learning and teaching implications.

Examines the history of special education by categorical areas (for example, Learning Disabilities, Mental Retardation, and Autistic Spectrum Disorders). This title includes chapters on the changing philosophy related to educating students with exceptionalities as well as a history of legal and legislation content concerned with special education.
