Pauling: Charismatic, Controversial, and Tough
Book Review of "Linus Pauling: A Man and His Science" by Anthony Serafini, Paragon House, 1989
Discussing controversial issues in the classroom
Discussion is widely held to be the pedagogical approach most appropriate to the exploration of controversial issues in the classroom, but surprisingly little attention has been given to the questions of why it is the preferred approach and how best to facilitate it. Here we address ourselves to both questions.We begin by clarifying the concept of discussion and justifying it as an approach to the teaching of controversial issues.We then report on a recent empirical study of the Perspectives on Science AS-level course, focusing on what it revealed about aids and impediments to discussion of controversial ethical issues
Modern merthods and a controversial surname: Plant
In the past few years, DNA testing has begun to contribute to our understanding. It is currently emerging more clearly which surnames are multi-origin, originating with many different forefathers, and which descend from a single male ancestor.
As a case study, I shall describe the application of modern, multidisciplinary methods to the surname Plant, which has been ascribed a different meaning each time an authority has written about it. The recent emergence of a different view anout this name's origins has prompted a reassessment of its meaning
Teaching and learning about controversial science issues
The overarching Nature of Science (NoS) strand in our revised science curriculum presents teachers of science with a number of challenges. One of them is the ‘Participating and Contributing’ achievement aim with its focus on controversial science issues (CSI). This article reports on a new classroom model for exploring controversial science issues with students that was trialled in New Zealand science classrooms, writes Dr. Kathy Saunders, the University of Waikato
The controversial piston in the thermodynamic limit
We consider the evolution of a system composed of non-interacting point
particles of mass in a container divided in two regions by a movable
adiabatic wall (adiabatic piston). In this talk we discuss the thermodynamic
limit where the area of the container, the number of particles, and the
mass of the piston go to infinity keeping and
fixed. We show that in this limit the motion of the piston is deterministic.
Introducing simplifying assumptions we discuss the approach to equilibrium and
we illustrate the results with numerical simulations. The comparison with the
case of a system with finite will be presented. We consider the
