Why braille reading is important and how to study it /Por qué es importante la lectura en braille y cómo estudiarla
2016
AbstractDespite its relevance in theoretical and practical terms, braille reading has received little attention from researchers. Awareness of the pros and cons of the different procedures used to examine braille reading is needed to facilitate the realization of systematic studies and to improve teaching methods in braille reading. This study provides a critical examination of braille reading methods and highlights key points for future studies on tactile reading.
Developing a Pedagogical Framework and Design Principles for STEM Learning Environment Design
2020
The need for effective and attractive learning environments (LEs) for science, technology, engineering, and mathematics (STEM) has been internationally recognized. Additionally, the connection between STEM learning and cross-curricular skills such as creativity, innovation, and entrepreneurship has garnered attention. A deep theoretical and empirical understanding is required when designing STEM LEs. In this study, a pedagogical framework for STEM LEs has been developed based on feedback from students, aged 10–18 years old, teachers, school directors, parents, and STEM professionals, and supported by the literature. First, representatives of key stakeholder groups in Belarus, Finland, Germa…
Visual cues improve students’ understanding of divergence and curl: Evidence from eye movements during reading and problem solving
2019
The coordination of multiple external representations is important for learning, but yet a difficult task for students, requiring instructional support. The subject in this study covers a typical relation in physics between abstract mathematical equations (definitions of divergence and curl) and a visual representation (vector field plot). To support the connection across both representations, two instructions with written explanations, equations, and visual representations (differing only in the presence of visual cues) were designed and their impact on students’ performance was tested. We captured students’ eye movements while they processed the written instruction and solved subsequent c…

Phonon Driven Floquet Matter.
2018
The effect of electron–phonon coupling in materials can be interpreted as a dressing of the electronic structure by the lattice vibration, leading to vibrational replicas and hybridization of electronic states. In solids, a resonantly excited coherent phonon leads to a periodic oscillation of the atomic lattice in a crystal structure bringing the material into a nonequilibrium electronic configuration. Periodically oscillating quantum systems can be understood in terms of Floquet theory, which has a long tradition in the study of semiclassical light-matter interaction. Here, we show that the concepts of Floquet analysis can be applied to coherent lattice vibrations. This coupling leads to p…
Pedagogika katolicka – znaczenie i aktualność w kontekście chaosu wartości (perspektywa polska)
2017
Education cannot be reduced to information and should guarantee to the students and their parents the freedom of making axiological decisions and solutions. The above mentioned right is confimed by the right of parents to raise their children according to their own conceptions. In the contemporary chaos of values and principles of education the Catholic education remains a topical, interesting and important proposal for school.

Istota budżetu gminy w gospodarce komunalnej i mieszkaniowej
2016
The municipality independently manages the finances. The plan of incomes and expenses the municipality passed a by law for a period of one calendar year. The draft budget is developing management based on the budget law and the guidelines of the municipal council, the municipal council adopts while. The revenues of local government units are public funds collected by these units from individuals, legal persons and entities without legal personality, as well as funds received from the state budget in the form of subsidies and grants for the implementation of specific tasks. However, the revenue received is not always sufficient to meet all the needs of the residents. Municipal authorities ha…

Cavity Control of Excitons in Two-Dimensional Materials
2018
We propose a robust and efficient way of controlling the optical spectra of two-dimensional materials and van der Waals heterostructures by quantum cavity embedding. The cavity light-matter coupling leads to the formation of exciton-polaritons, a superposition of photons and excitons. Our first principles study demonstrates a reordering and mixing of bright and dark excitons spectral features and in the case of a type II van-der-Waals heterostructure an inversion of intra and interlayer excitonic resonances. We further show that the cavity light-matter coupling strongly depends on the dielectric environment and can be controlled by encapsulating the active 2D crystal in another dielectric m…
