Didactic Design of Teaching Materials Created by Future Teachers in the Czech Republic

This paper describes research on the didactic design of teaching materials created by Czech future teachers in their university theses. The results of the research indicate that the teaching materials for future teachers are far from achieving the highest level of didactic design. The average value of the coefficient of the total didactic design is only 26%. The weakest aspect of the teaching materials is the component of the learning management system. This fact implies a significant underestimation of the learning process. Students preparing for the teaching profession have not demonstrated the ability to compile didactically well-developed teaching material in their final theses. They use only a limited number of structural components, and therefore the basic function of teaching materials, the didactic function, is not fully fulfilled. The didactic function ensures the effective usability of textbooks and similar texts in actual education

Research on the quality of teaching professional subjects in the fields of trade and services using didactic case studies

Příspěvek je zaměřen na výzkum kvality výuky odborných předmětů obchodu a služeb gastronomického zaměření v České republice. V úvodu empirické studie jsou vymezeny možnosti kvalitativního výzkumu kvality výuky odborných předmětů oborů obchodu a služeb v oblasti gastronomie. Dále je prezentována původní didaktická kazuistika, která vznikla ve spolupráci s učitelkou tohoto oboru na střední odborné škole gastronomického zaměření v Jihomoravském kraji (Znojmo). Cílem kazuistiky je zhodnotit danou výukovou situaci dotčeného odborného předmětu z hlediska ukazatelů kvality výuky.The contribution is focused on researching the quality of teaching vocational subjects of trade and catering services in the Czech Republic. In the introduction of the empirical study, the possibilities of qualitative research into the quality of teaching professional subjects in trade and services in the field of gastronomy are defined. Furthermore, the original didactic case study is presented, which was created in cooperation with a teacher of this field at a secondary vocational school specializing in gastronomy in the South Moravian Region (Znojmo). The goal of the case study is to evaluate the given teaching situation of the concerned professional subject from the point of view of teaching quality indicators.O

Title in English: 14th International Scientific Conference Didactic Conference 2021: Proceedings Didactics of mathematics, natural sciences and vocational education represent developing areas and are a breeding ground for new ideas and approaches. In mathematics and physics, the proceedings provide an overview of the historical development of education process and the possibilities of activating students. From a practical point of view, physics and chemistry are interconnected by using simulations in teaching. Vocational education is represented from various perspectives, whether in technical education, by solving logistical problems, or educational activities in the teaching of economic subjects. Due to the current situation, there are abundant contributions on the effects of the ongoing pandemic on the educational process and distance learning

Sr(II) and Ba(II) Alkaline Earth Metal–Organic Frameworks (AE-MOFs) for Selective Gas Adsorption, Energy Storage, and Environmental Application

Two new alkaline earth metal–organic frameworks (AE-MOFs) containing Sr(II) (UPJS-15) or Ba(II) (UPJS-16) cations and extended tetrahedral linker (MTA) were synthesized and characterized in detail (UPJS stands for University of Pavol Jozef Safarik). Single-crystal X-ray analysis (SC-XRD) revealed that the materials are isostructural and, in their frameworks, one-dimensional channels are present with the size of ~11 × 10 Å2. The activation process of the compounds was studied by the combination of in situ heating infrared spectroscopy (IR), thermal analysis (TA) and in situ high-energy powder X-ray diffraction (HE-PXRD), which confirmed the stability of compounds after desolvation. The prepared compounds were investigated as adsorbents of different gases (Ar, N2, CO2, and H2). Nitrogen and argon adsorption measurements showed that UPJS-15 has SBET area of 1321 m2 g−1 (Ar) / 1250 m2 g−1 (N2), and UPJS-16 does not adsorb mentioned gases. From the environmental application, the materials were studied as CO2 adsorbents, and both compounds adsorb CO2 with a maximum capacity of 22.4 wt.% @ 0 °C; 14.7 wt.% @ 20 °C and 101 kPa for UPJS-15 and 11.5 wt.% @ 0°C; 8.4 wt.% @ 20 °C and 101 kPa for UPJS-16. According to IAST calculations, UPJS-16 shows high selectivity (50 for CO2/N2 10:90 mixture and 455 for CO2/N2 50:50 mixture) and can be applied as CO2 adsorbent from the atmosphere even at low pressures. The increased affinity of materials for CO2 was also studied by DFT modelling, which revealed that the primary adsorption sites are coordinatively unsaturated sites on metal ions, azo bonds, and phenyl rings within the MTA linker. Regarding energy storage, the materials were studied as hydrogen adsorbents, but the materials showed low H2 adsorption properties: 0.19 wt.% for UPJS-15 and 0.04 wt.% for UPJS-16 @ −196 °C and 101 kPa. The enhanced CO2/H2 selectivity could be used to scavenge carbon dioxide from hydrogen in WGS and DSR reactions. The second method of applying samples in the area of energy storage was the use of UPJS-15 as an additive in a lithium-sulfur battery. Cyclic performance at a cycling rate of 0.2 C showed an initial discharge capacity of 337 mAh g−1, which decreased smoothly to 235 mAh g−1 after 100 charge/discharge cycles
