Developing Integrated Arts Curriculum in Hong Kong: Chaos Theory at Work?
Peer reviewed Peer reviewed
Direct linkDirect link
Wong, Marina – Curriculum Inquiry, 2013
This article reports the development of integrated arts curriculum in two Hong Kong secondary schools over a 9-year period. Initial findings display a range of individual responses to educational change that are both non-predictable and non-linear. Chaos theory is used to explain these varied responses in terms of bifurcations. The findings of…

Pre-Service Teachers' Knowledge of Relational Structure of Physics Concepts: Finding Key Concepts of Electricity and Magnetism
Peer reviewed Peer reviewed
PDF on ERIC Download full text
Koponen, Ismo T.; Nousiainen, Maija – Education Sciences, 2019
Relational interlinked dependencies between concepts constitute the structure of abstract knowledge and are crucial in learning conceptual knowledge and the meaning of concepts. To explore pre-service teachers' declarative knowledge of physics concepts, we have analyzed concept networks, which agglomerate 12 pre-service teacher students'…

Static Solutions of Einstein's Equations with Cylindrical Symmetry
Peer reviewed Peer reviewed
Direct linkDirect link
Trendafilova, C. S.; Fulling, S. A. – European Journal of Physics, 2011
In analogy with the standard derivation of the Schwarzschild solution, we find all static, cylindrically symmetric solutions of the Einstein field equations for vacuum. These include not only the well-known cone solution, which is locally flat, but others in which the metric coefficients are powers of the radial coordinate and the spacetime is…
