Abstract

This study aimed to analyze the mathematical literacy of university students in solving Higher-Order Thinking Skills (HOTS)-based problems on geometric transformations in an Advanced Mathematics course. A descriptive qualitative approach was employed, involving six participants selected through purposive sampling to represent high-, medium-, and low-ability groups. Data were collected using a written HOTS-based mathematics test and analyzed following the data analysis model of Miles, Huberman, and Saldaña. The findings indicate that students' mathematical literacy can be classified into three categories: (1) accurate and appropriate visual representations, (2) inaccurate visual representations, and (3) absence of visual representations. Students in the high-ability category successfully demonstrated all indicators of mathematical literacy, including problem comprehension, solution strategy development, mathematical representation, visualization, and logical reasoning. Students in the medium-ability category exhibited partial understanding but still experienced conceptual misunderstandings and weaknesses in visualization. In contrast, students in the low-ability category were unable to integrate symbolic and visual representations effectively and demonstrated deficiencies across nearly all mathematical literacy indicators. These findings suggest that visual representation is a key factor in successfully solving HOTS-based geometric transformation problems. Therefore, mathematics instruction should be designed using contextual, visual, and HOTS-oriented learning approaches to enhance university students' mathematical literacy.

Abstract

Superconductivity is a phenomenon in which a material exhibits zero electrical resistance and perfect diamagnetism through the Meissner effect when cooled below its critical temperature. In type-II superconductors, critical magnetic field parameters, including Hc1H_{c1}Hc1​, Hc2H_{c2}Hc2​, and HirrH_{\mathrm{irr}}Hirr​, play essential roles in determining the stability of the superconducting phase under external magnetic fields. This review discusses the relationship among the Meissner effect, critical magnetic fields, magnetic vortices, flux pinning, synthesis methods, and the applications of high-temperature superconductors (HTSs), particularly YBCO and BSCCO. The reviewed studies indicate that microstructure, doping, and crystal quality strongly influence critical magnetic field performance and superconducting stability. However, previous studies have generally examined the Meissner effect and critical magnetic fields separately. Therefore, a more comprehensive review is needed to integrate recent developments in the theory, experimental investigation, and applications of modern superconductors.
