... among observable quantities associated with such processes, the ability to relate measurements made by different observers lies at the very foundation of theoretical, experimental, and computational physics. Rich technological applications of these ideas have enabled us both to keep tabs on the location...

... of physics, if not the most important ( Coopersmith, 2010 ). Energy is an abstract, imponderable idea ( Harrer, 2017 ), the relevance of which solely derives from the fact that it is a conserved quantity ( Feynman et al., 2011 ). The fact that energy is a conserved quantity is essential...

... productive and unproductive resources and eschewing descriptions of difficulties. One such analysis of student reasoning with the concept of heat further focuses on the language, using perspectives from linguistics. Distinctions between closely related quantities An ongoing theme of the early work...

... pressure as a quantity without direction and consider or calculate it on a surface. Students incorrectly also associated the pressure with “confinement” similar to the “packed crowd” model described above. Students (40%) who use the “pressing force” model consider pressure in the wide vessel as greater...

... knowledge is an elusive proposition since the term has different meanings in different subfields. In PER, conceptual knowledge most commonly refers to a qualitative knowledge of physical quantities and the relations between them (e.g., McDermott, 1991 ). This view of conceptual knowledge is commonly...

... theories of learning as a context, to implement STEM epistemology to Support Experiential Learning of Students ( Kalovrektis et al., 2017 ). Table 6.1 Variables list. Name Measured quantity Name Measured quantity Name Measured quantity h Height of vertical...

... of strain is described as the ratio of two like quantities (change in dimension/original dimension), coefficients of strain tensor are dimensionless. ℂ and S are fourth-rank property tensors; ℂ i j k l are the elastic stiffness coefficients given in the units of N/m²...

... extracting information without looking at the actual data points. The focus is on the diagram frame and coordinate axes. The following activities take place during the identification process: assignment of the quantities to the axes, determination of the scale range and, if several data series are shown...

... about adding electric fields: the fraction of correct responses dropped to below the pre-instruction level, and many more students added the electric fields of two identical charges as if they were scalar quantities. After the introduction of the magnetic field (a vector quantity), the numbers recovered...

... are structured, but to answer the subtasks, very simple experiments must be performed or even designed in which only a few quantities are measured, the data are reported in an orderly fashion, and conclusions are drawn from the measurements. Without performing the experiments correctly, the tasks cannot...

... interference between energy as several entities with different forms, and its presentation as a unitary quantity based on the definition of work. There is evidence that even science teachers fail to reconcile the “energy forms” view and the formal definitions of energy ( Lehavi and Eylon, 2014 ). The lack...

....” This statement could form the common misconception that if there is a voltage, there should be a current. This is not always correct. Another study by Yildiz (2015) focused on the expression “All quantities can be converted into length, time and mass units in the end. No matter how complex any physical...

... problems) or the invariance of quantities under transformation (conservation of quantities). This endows mathematics with modeling and predicting power in physics. On the whole, mathematics provides structures for enhancing a deeper understanding of the world and especially the physics processes that take...

... of the mathematization of electromagnetics at that time. However, the objections of Faraday and others were largely forgotten. For example, Maxwell insisted that natural philosophy should be mathematics because laws related to quantities must be dealt with in accordance with precise reasoning principles. Due...

... measurement process (i.e a polarized photon on a polaroid) vs the epistemic character of probability in CM (i.e., prevision of a tossing coin) Physical meaning of the uncertainty relations (existence of physical quantities pairs that cannot be simultaneously determined with arbitrary precision...

... for physical quantities (acceleration, position…), while these measurements were connected to students' daily life through sensors integrated into clothes or toys ( Tiemann et al., 2003 ; and Orfanakis et al., 2004 ). In the same spirit, the MediaLab "Toys of Tomorrow" program was created...

... in an active manner in the ISLE approach) that follows, under the guidance of the instructor, they work in pairs on a set of activities and discuss what physical quantities might affect the magnitude of the current and invent the quantity of magnetic flux. There, they also worked on the activities to invent...

... is “changing parameters.” When this interpretive device is activated, it allows the student to imagine how one quantity varies while others are held constant. Sherin argued that students who study algebra-based physics as opposed to computational-based physics are likely to acquire different interpretive...

..., such as argumentation and visual representations, appear to students through the textbooks and how these affect teacher practices ( McNeill et al., 2016 ). Frameworks for Analyzing Textbooks Textbooks have been assessed according to different criteria such as gender equality ( Elgar, 2004 ), the quantity...
