Abstract

Purpose of the study: This study aimed to design, refine, and evaluate Photonics Explorer Kit (PEK)-supported inquiry activities for enhancing preservice physics teachers’ conceptual understanding of optics, particularly in reflection, refraction, and diffraction. Methodology: The study employed Educational Design Research (EDR) involving two iterative cycles with 89 level 200 preservice physics teachers at the University of Education, Winneba, Ghana. Cycle 1 involved 51 participants, while Cycle 2 involved 38 participants. Data were collected using a validated two-tier diagnostic test and analysed using descriptive statistics, paired-samples t-tests, effect sizes, and comparison of learners’ correct conceptions, partial conceptions, misconceptions, and no-explanation responses. Main Findings: The findings showed significant improvement in participants’ conceptual understanding in both cycles. In Cycle 1, mean scores increased from 7.75 to 11.14, t(50) = 25.78, p < .001, d = 1.95. In Cycle 2, mean scores increased from 8.10 to 12.46, t(37) = 29.84, p < .001, d = 2.34. Cycle 2 also recorded higher correct conceptions and fewer misconceptions across the assessed optics concepts. Novelty/Originality of this study: The study presents an Educational Design Research-based approach for refining PEK-supported 7E inquiry activities in optics. It shows how iterative refinement of instructional support, diagrams, inquiry questions, and multimedia can strengthen preservice physics teachers’ conceptual understanding in optics, especially in resource-constrained physics teacher education contexts.

Abstract

Purpose of the study: This study aims to develop an alternative theoretical approach for describing entropy and Einstein temperature in solids. The proposed framework seeks to provide a simpler and more consistent understanding of the thermal behavior of solids while offering new insights into their thermodynamic properties. Methodology: This study employed a theoretical and analytical research method based on the Einstein model of solids and classical thermodynamics. Mathematical derivations and analytical calculations were used to develop the proposed approach. No experimental tools, survey, statistical analysis, or commercial software were used. Standard mathematical notation and symbolic analysis were applied. Main Findings: The proposed approach produced an alternative expression for entropy and a revised definition of Einstein temperature for solids. The derived relations were mathematically consistent with thermodynamic principles, simplified the description of thermal behavior, and provided a unified framework for analyzing entropy and characteristic temperature in solid-state systems. Novelty/Originality of this study: This study introduces a new theoretical formulation of entropy and an alternative definition of Einstein temperature for solids. The proposed framework simplifies conventional thermodynamic treatment, offers a more coherent interpretation of thermal properties, and expands the theoretical understanding of solid-state thermodynamics by providing an alternative perspective to existing models.

Abstract

Purpose of the study: This study aimed to characterize the spatial and temporal variation of b-value in the southern Java subduction zone and identify areas exhibiting distinctive seismicity patterns through an integrated analysis of earthquake magnitude distribution, seismic activity, and associated estimation uncertainty. Methodology: Earthquake data from the BMKG and NEIC-USGS catalogues covering 1973–2011 were processed through magnitude homogenization, declustering, and magnitude-completeness assessment. The Gutenberg–Richter relationship and maximum-likelihood estimation were applied using ZMAP V.06 implemented in MATLAB 7.04. Spatial analysis used 0.1° × 0.1° grids with 80 events per calculation, while temporal variation was evaluated using a moving-window approach. Novelty/Originality of this study: This study integrates regional, spatial, temporal, and uncertainty analyses of b-value to provide a differentiated characterization of seismicity across southern Java. By combining Gutenberg–Richter parameters, spatial mapping, moving-window analysis, and standard-deviation assessment, the study demonstrates that regional-average b-values can conceal localized seismic regimes and provides a more comprehensive framework for interpreting seismic heterogeneity.

Abstract

Purpose of the study: The goal of this work is to present a comparative study between the semi-relativistic theory of Sakho and the relativistic theory of Dirac applied to calculations of the eigenvalue of the Hamiltonian fine structure of the hydrogen like systems. The three small perturbative corrections (relativistic mass correction, spin-orbit coupling, and the Darwin term) of the Hamiltonian are considered. Methodology: This research is based on correction of the semi-classical Bohr’s theory on the hydrogen like systems considering the relativistic mass correction by ignoring the electron’s spin. This approach referred to as semi-relativistic theory allows one to express the eigenvalues of the Hamiltonian fine structure to be compared to that from the relativistic wave function of Dirac Main Findings: The research gives the first expression of the quantized energy of hydrogen like systems taking only into account, the relativistic mass correction.   This result provides exactly the eigenvalues of the Hamiltonian fine structure predicted from Dirac’s relativistic theory for all the non-degenerated quantum states n2Lj (j = l ± s) of the hydrogen like systems (i.e.  1 2s1/2, 2 2p3/2, 3 2d5/2, 42f7/2, and so on). Novelty/Originality of this study: Theoretical determination of the eigenvalue of the Hamiltonian fine structure predicted from Dirac’s relativistic theory for all the non-degenerated quantum states is obtained with a soft semi-relativistic theory without including in the calculations the spin-orbit coupling and the Darwin term corrections.
