...), the resources about waves seem to be constructed on the fly from more solid and stable sources, but not entirely appropriate resources about particles. They are still very plastic and have not yet been solidified by evaluation and re-evaluation. This would explain why they seem to mix up apparently incompatible...

... to the students. The task is listed as part of the entire exam so that students can return to the task later even if they no longer have experimental equipment. The required equipment for a student and the expected experimental setup are shown in Fig. 13.2 . A mug with hot water, a glass of cold water, plastic...

... that highlight the similarities between the micro/particle-level mechanisms in a physics context (e.g., charge separation when rubbing a plastic rod) and other disciplinary contexts (e.g., charge separation in an electrochemical cell). We believe that by grounding within the same curriculum microlevel...

... in the room because ‘they are colder than the plastic ones.’” The first of the choices for this question is “Jim agrees and says, ‘They are colder because metal is naturally colder than plastic.’” The authors describe efforts to validate the instrument in general terms, illustrating its content and construct...

.... (1987) investigated the use of Andersson's (1986) general constructs (or “Gestalts of causation”) when primary school children expressed their ideas about plastic strip magnets. They asked 119 primary school students in year 2, 4, and 6 in a demonstration interview to predict whether an old or a new...

... homework problems that include no observations or data. In RealTime Physics, as in many physics labs, the equipment is designed to create an idealized version of the real world. Through low friction motion carts, low friction pulleys, and plastic wheels with negligible mass and moment of inertia...

... optical experiments” (p. 61). Van Domelen (1999) introduced an artificial right-hand rule device that is made of a clear, plastic rectangular prism with vector arrows on three sides. This tool can assist students who have dexterity difficulties, students without right hands and/or the fingers used...

... et al., 1999 ; and Lee and Choi, 2008 ). However, the material properties of silicone rubber are highly sensitive to both pressure and temperature. Even a small pressure field can cause plastic deformation in silicone rubber based sensors. Moreover, its properties also depend significantly...

... deposition modelling In fused deposition modelling, an extrusion nozzle fixed to a printing head receives the supply of a thermoplastic filament. In a layer-by-layer approach, the plastic is melted and extruded onto a building platform according to the geometry of each layer of the final object, after...

At unloading time the material regains its original state only when the applied force should...
