.... The historical record is clear: controversies occurred throughout its progression, especially when established theories clashed with competing views: geo-centrism vs helio-centrism; Huygens vs Newton on the nature of light; Leibniz vs Newton on the nature of space, gravity and action-at-a-distance ( Dainton...

... of teaching activities supported by research and empirically adapted to students' reasoning ( Psillos and Kariotoglou, 2015 ). TLS design reflects how developing tools and learning environments relate to developing educational theory. This interrelation is a complex cyclical process where general education...

Hierarchies of skills (Fisher) Skill-theory ( Fisher, 1980 ) is a well-known and straight-forward approach to assume a hierarchy (of skills) that appears in the course of the development starting at birth. Fisher's approach has the benefits...

... concepts and the high school classroom dynamic. Through classroom observations, he found that students are so invested in the one-fluid electron theory that a two-fluid model simply did not make sense to them. In two pivotal successive lessons, his students first found experimentally that metals cannot...

... The modern understanding of physics problem solving is heavily influenced by early developments in information-processing models of cognition. Information-processing theories view problem solving as the construction of and navigation through a problem space—a representation of the problem...

... of art and media such as Interstellar and Gravity. Looking back at many kinds of literacies, SL is crucial in achieving them. Scientific methods and processes are essential to understand how data is generated and analyzed with respect to data and information literacy. Our concern with physics literacy...

... possess a knowledge of particle theory of matter ( Treagust et al., 2002 ). When it comes to properties of matter, children do not easily make use of abstract ideas about particles. According to Kind (2004) , they rely mainly on sensory information up to the age of around 14 years. Two mental...

...), but the anecdotal history of physics is full of romanticized episodes where theories are apparently born fully fledged in the mind of a scientific genius. Famous examples are Archimedes' shout of “Eureka” from his bath, Newton's falling apple giving rise to his theory of gravity, or the youthful Einstein chasing...

To establish clear links between the research objectives and the summary findings derived from the raw data, and to ensure that these links are both transparent (demonstrable to others) and defensible (justifiable given the objectives of the research) ( Gee, 2004 ); and To develop a model or theory about...

The relevant contrast case is probably not with physics as a non-human endeavor. Considering all the material, non-human...

Optimal operation of the primary separation vessel (PSV) is critical to ensure that the maximum possible amount...
