Abstract: This thesis reports on a learning study that employed variation theory to enhance a domain-specific generic-capability pedigree analysis of Hong Kong secondary five students so as to help them develop their capability to solve pedigree problems. Pedigree analysis is a study of inheritance in genetics, which includes the deduction of dominant and recessive characters. The literature and local examination reports suggested that solving pedigree problems is difficult for students, as the process of deduction demands conceptual understanding and use of scientific language. Three biology teachers participated in this learning study using variation theory. Teachers shifted the focus of lesson observation from teaching performance to student learning, to how students deduced the dominant character from pedigree problems, which was the object of learning. To explore the effectiveness of such teaching and learning to solve pedigree problems through different patterns of variation, two cycles of learning study were conducted in two senior biology classes. Results showed that students were more able to deduce the dominant character with relevant genetic principles by experiencing the variations. Both conceptual understanding and scientific language are critical aspects of solving pedigree problems. This study also suggests that explanatory scientific writing needs to be broken down into different components and then differentiated patterns of variation designed to let students discern those components and their relationships; in that way their writing can be 'scaffolded' in a stepwise manner rather than giving them the whole writing framework at once. However, the identification of critical features and patterns of variation and their relevance to the object of learning should be considered carefully and explored further.

Book Description
First released in the Spring of 1999, How People Learn has been expanded to show how the theories and insights from the original book can translate into actions and practice, now making a real connection between classroom activities and learning behavior. This edition includes far-reaching suggestions for research that could increase the impact that classroom teaching has on actual learning. Like the original edition, this book offers exciting new research about the mind and the brain that provides answers to a number of compelling questions. When do infants begin to learn? How do experts learn and how is this different from non-experts? What can teachers and schools do-with curricula, classroom settings, and teaching methodsâ€"to help children learn most effectively? New evidence from many branches of science has significantly added to our understanding of what it means to know, from the neural processes that occur during learning to the influence of culture on what people see and absorb. How People Learn examines these findings and their implications for what we teach, how we teach it, and how we assess what our children learn. The book uses exemplary teaching to illustrate how approaches based on what we now know result in in-depth learning. This new knowledge calls into question concepts and practices firmly entrenched in our current education system. Topics include: How learning actually changes the physical structure of the brain. How existing knowledge affects what people notice and how they learn. What the thought processes of experts tell us about how to teach. The amazing learning potential of infants. The relationship of classroom learning and everyday settings of community and workplace. Learning needs and opportunities for teachers. A realistic look at the role of technology in education.

NEW IN PAPERBACK FEBRUARY 2005! `The most systematic and wide-ranging survey of the multi-faceted field of International Relations yet produced. It is sure to become a standard reference work and teaching text, and is unlikely to be superseded at any time in the near future. It should be considered as essential reading′ - International Affairs The Handbook of International Relations, published 2002 in hardback, quickly established itself as the benchmark volume, providing a state-of-the-art review and indispensable guide to the study of international relations. It is now released in paperback, in order to be accessible to students in classroom use. Divided into three parts, the volume reviews both the historical, philosophical, analytical and normative roots to the discipline and the key contemporary topics of research and debate today. The first part introduces the major approaches within the field and unpacks many of the on-going debates within the discipline including those between rationalist and constructivist approaches. The second part moves on to explore the key concepts and contextual factors important to the subject from concepts like the state and power, to international and transnational actors, debates around globalization, and contending feminist perspectives. The final part reviews a number of the key substantive issues in international relations and is designed to complement the analytical tools and perspectives presented in Parts I and II. Examples of the many topics included are: foreign policy; war and peace; security; nationalism and ethnicity; finance; trade; development; the environment; and human rights.

Book Description
Raising hopes for disease treatment and prevention, but also the specter of discrimination and "designer genes," genetic testing is potentially one of the most socially explosive developments of our time. This book presents a current assessment of this rapidly evolving field, offering principles for actions and research and recommendations on key issues in genetic testing and screening. Advantages of early genetic knowledge are balanced with issues associated with such knowledge: availability of treatment, privacy and discrimination, personal decision-making, public health objectives, cost, and more. Among the important issues covered: Quality control in genetic testing. Appropriate roles for public agencies, private health practitioners, and laboratories. Value-neutral education and counseling for persons considering testing. Use of test results in insurance, employment, and other settings.

Book Description
Education is a hot topic. From the stage of presidential debates to tonight's dinner table, it is an issue that most Americans are deeply concerned about. While there are many strategies for improving the educational process, we need a way to find out what works and what doesn't work as well. Educational assessment seeks to determine just how well students are learning and is an integral part of our quest for improved education. The nation is pinning greater expectations on educational assessment than ever before. We look to these assessment tools when documenting whether students and institutions are truly meeting education goals. But we must stop and ask a crucial question: What kind of assessment is most effective? At a time when traditional testing is subject to increasing criticism, research suggests that new, exciting approaches to assessment may be on the horizon. Advances in the sciences of how people learn and how to measure such learning offer the hope of developing new kinds of assessments-assessments that help students succeed in school by making as clear as possible the nature of their accomplishments and the progress of their learning. Knowing What Students Know essentially explains how expanding knowledge in the scientific fields of human learning and educational measurement can form the foundations of an improved approach to assessment. These advances suggest ways that the targets of assessment-what students know and how well they know it-as well as the methods used to make inferences about student learning can be made more valid and instructionally useful. Principles for designing and using these new kinds of assessments are presented, and examples are used to illustrate the principles. Implications for policy, practice, and research are also explored. With the promise of a productive research-based approach to assessment of student learning, Knowing What Students Know will be important to education administrators, assessment designers, teachers and teacher educators, and education advocates.
