This study examines the impact of organizational purposes and values on reforming physics instruction to align with a practice-based instructional approach, in a case of engaging in infrastructuring with a no-excuses charter network. The network's instruction was guided by organizational purposes of ensuring predictable academic success and…

This book has three sections on the role of technology in education. The first section covers the merits of online learning and environment. The second section of the book gives insight on new technologies in learning and teaching. The third section of the book underlines the importance of new tendencies for the technology in education. There is a…

The discipline-based education research (DBER) report from the National Research Council (2012) highlighted the existence of a research-practice gap in science instruction in higher education and the need to identify strategies to close it. This study hypothesizes that one potential factor is instructors' access to research-based…

Faculty often wish to devote time and resources to improve a course to be more in line with principles of how people learn but are not sure of the best path to follow. We present our tested approach to research-based course transformation, including development of learning goals, instructional materials based on student difficulties, and…

Shows that the entropy change during the temperature equilibration of an isolated collection of systems which may exchange heat (but not work) energy is positive when the constant-volume heat capacity of each system is a non-negative function of the temperature. (MLH)

Explains the necessity for a domain concept in understanding ferromagnetism and discusses various factors influencing the domain configuration in a crystal. (MLH)

Investigates a sequence of inelastic collisions resulting among three spheres, whose centers are on a line, when at the outset the leftmost sphere is propelled to the right and the other two spheres are at rest. Expressions are obtained for velocity, time, and distance variables. (MLH)

Presents a mathematical treatment of optical propagation in crystals as an eigenvalue problem involving a real symmetrical dyadic. (MLH)

Shows that local equilibrium and energy considerations in an elastic dielectric crystal lead to a simple derivation of the Maxwell stress tensor in anisotropic dielectric solids. The resulting equilibrium stress-strain relations are applied to determine the deformations of a charged parallel plate capacitor. (MLH)

Advances new explanations for false observations made during 1903-1906 concerning a spurious radiation called N rays. (MLH)

Presents a classical approximation of the equipartition theorem of thermodynamics. A canonical distribution is assumed and the calculations of Reif are followed to solve for the average potential energy per particle. (CP)

Discusses the quantization of angular momentum components, Heisenberg-type inequalities for their spectral dispersions, and the quantization of the angular momentum modulus, without using operators or commutation relations. (MLH)

Discusses the Stark effect of the plane rotator using a simple analysis of symmetry features and a careful application of degenerate perturbation theory. (MLH)

Discusses the construction of wave packets by superimposing bound-state eigenfunctions. Illustrates the infinite square well and the infinite square well with a delta-function barrier. (MLH)

Discusses the uses of the Gelfand-Levitan formulation of the inverse problem as a source of exactly solvable bound-state models that are suitable for examples in quantum mechanics courses. (MLH)
