Models and Modelling in Physics Education: A Critical Re-analysis of Philosophical Underpinnings and Suggestions for Revisions
The model-based view (MBV) of science education, which strives for authenticity in science teaching, is currently seeking support from the philosophical positions related to the Semantic View ofExpand

Coherent Knowledge Structures of Physics Represented as Concept Networks in Teacher Education
A characteristic feature of scientific knowledge is the high degree of coherence and connectedness of its conceptual structure. This notion is also behind the widely accepted instructional method ofExpand

Concept Development in Learning Physics: The Case of Electric Current and Voltage Revisited
In learning conceptual knowledge in physics, a common problem is the development and differentiation of concepts in the learning process. An important part of this development process is theExpand

Instability and wavelength selection during step flow growth of metal surfaces vicinal to fcc(001).
We study the onset and development of ledge instabilities during growth of vicinal metal surfaces using kinetic Monte Carlo simulations. We observe the formation of periodic patterns at [110] closeExpand

CONCEPTS AND LAWS AS NETWORK-STRUCTURES : COMPARISONS OF STRUCTURAL FEATURES IN EXPERTS ’ AND NOVICES ’ CONCEPT MAPS
A characteristic feature of physics knowledge is the high degree of coherence and connectedness of its concepts. To large degree physics concepts and laws can be viewed as organized, network-likeExpand

Island diffusion on metal fcc(100) surfaces
We present Monte Carlo simulations for the size and temperature dependence of the diffusion coefficient of adatom islands on the Cu(100) surface. We show that the scaling exponent for the sizeExpand

Morphology of ledge patterns during step flow growth of metal surfaces vicinal to fcc (001)
The morphological development of step edge patterns in the presence of meandering instability during step flow growth is studied by simulations and numerical integration of a continuum model. It isExpand

Atomic mixing in ion‐bombardment‐induced temperature spikes in metals
The theory of temperature spikes is generalized to account for the coupling between conduction electrons and lattice atoms. This theory is used to revise the phenomenological model of atomic mixing.Expand

Systemic view of learning scientific concepts: A description in terms of directed graph model
TLDR
This study suggests a systemic view on concept learning, in which concepts are seen as complex, dynamically evolving structures with robust and persistent patterns emerging from loosely connected elemental pieces. Expand
