Chemistry seeks to provide qualitative and quantitative explanations for the observed behaviour of elements and their compounds. Doing so involves making use of three types of representation: the macro (the empirical properties of substances); the sub-micro (the natures of the entities giving rise to those properties); and the symbolic (the number of entities involved in any changes that take place). Although understanding this triplet relationship is a key aspect of chemical education, there is considerable evidence that students find great difficulty in achieving mastery of the ideas involved. In bringing together the work of leading chemistry educators who are researching the triplet relationship at the secondary and university levels, the book discusses the learning involved, the problems that students encounter, and successful approaches to teaching. Based on the reported research, the editors argue for a coherent model for understanding the triplet relationship in chemical education.
Contains nineteen essays in which the authors discuss issues related to teaching and learning in science and mathematics, discussing the need to determine student understanding, ways to improve curriculum and teaching, and methods of implementing teacher change.
Statistical models attempt to describe and quantify relationships between variables. In the models presented in this chapter, there is a response variable (sometimes called dependent variable) and at least one predictor variable (sometimes called independent or explanatory variable). When investigating a possible cause-and-effect type of relationship, the response variable is the putative effect and the predictors are the hypothesized causes. Typically, there is a main predictor variable of interest; other predictors in the model are called covariates. Unknown covariates or other independent variables not controlled in an experiment or analysis can affect the dependent or outcome variable an...
This book is a compilation of papers from the inaugural International Science Education Conference held at the National Institute of Education (Singapore). The title, Science Education at the Nexus of Theory and Practice, reflects a pressing yet ongoing concern worldwide to integrate theory and practice in science education and the reader will find something of interest to both science education practitioners and researchers.
The Culture of Science Education: Its History in Person features the auto/biographies of the professional lives of 22 science educators from 11 countries situated in different places along the career ladder within an ongoing narrative of the cultural history of the field. Many contributors began to identify as science educators at about the time Sputnik was launched but others were not yet born. Hence the book articulates the making of a field with its twists and turns that define a career as a scholar in science education. Through the eyes of the contributing scholars, the development of science education is seen in the United States and its spread to all parts of the world is tracked, lead...
The aim of this Handbook is to present a global overview of developments in education and policy change during the last decade. It has the objective of providing both a strategic education policy statement on recent shifts in education and policy research globally and offers new approaches to further exploration, development and improvement of education and policy making. The Handbook attempts to address some of the above issues and problems confronting educators and policy makers globally. Different articles seek to conceptualize the on-going problems of education policy formulation and implementation, and provide a useful synthesis of the education policy research conducted in different co...
In contemporary society, science constitutes a significant part of human life in that it impacts on how people experience and understand the world and themselves. The rapid advances in science and technology, newly established societal and cultural norms and values, and changes in the climate and environment, as well as, the depletion of natural resources all greatly impact the lives of children and youths, and hence their ways of learning, viewing the world, experiencing phenomena around them and interacting with others. These changes challenge science educators to rethink the epistemology and pedagogy in science classrooms today as the practice of science education needs to be proactive an...
This Reader brings together a wide range of material to present an international perspective on topical issues in science education today. In order to identify what themes should be addressed in the book, thirty-eight science educators from around the world responded to the question: 'What issues are currently important in science education in your country?' The outcome is this lively and authoritative Reader, which features topics as varied as: globalisation assessment pupil's views on science education environmental education teaching approaches teacher development multimedia and ICT constructivism. With a specially written introduction from the editor, providing a much-needed context to the current education climate, students of science education will find this Reader an important route map to further reading and understanding.
This book explores how teachers can navigate the complex process of managing change within the classroom. The chapters highlight the new challenges that have arisen with the emergence and introduction of educational technology as teachers find themselves having to be responsive to the needs and demands of multiple stakeholders. Traversing a range of conceptual, disciplinary and methodological boundaries, the editors and contributors investigate the tensions that impinge on research-based change and how to integrate directed changes into their education system and classroom. Subsequently, this volume argues that posing these questions leads to increased understanding of the possible long term effects of educational change, and how teachers can know whether their solutions are effective.
