Utilization of Cannabis Sativa in Teaching Chemistry
Stránská, Adéla ; Holada, Karel (advisor) ; Beneš, Pavel (referee)
The diploma thesis deals with Cannabis sativa. The aim is to focus on possible utilization of Cannabis sativa in teaching chemistry. The theoretical part describes the botany of cannabis, overviews phytocannabinoids, substances contained in cannabis, and it also includes wide use of cannabis in agriculture and industry. The practical part deals with the selection and arrangement of a possible curriculum about chromatography as the most affordable technique for analysis of cannabis at school, including the formulation of school experiment methodology using the thin-layer chromatography of Cannabis sativa extract to demonstrate the presence of phytocannabinoids. The practical part also includes the scheme of an educational project on cannabis and describes the latest techniques, as well as the methodology of work with them, which are suitable for analysis of phytocannabinoids.

Educational game activities with chemical theme
Černá, Martina ; Beneš, Pavel (referee)
The rigorous thesis deals with study of one of the method, which go to development of creative genius and activity of students, namely with game. The main goal of the thesis is to explore problems of the game activities, inclusive of conditions, possibilities and advantages of their introduce to teaching chemistry at the second grade of basic school and to present suggestions for their realization. The thesis contains also fifteen concrete game activities with their rules and methodical hints. By means of the guest-size pedagogical research, practised on the choiced sample of the pupils from six basic schools, the prediction, that the result of teaching with games are better than results of teaching, where game activities weren't used, was ratified.

A Multimedia Presentation of The Basics of Chemistry 1
Škarvada, Vladimír ; Pumpr, Václav (advisor) ; Beneš, Pavel (referee)
Hlavním cílem diplomové práce je navrhnout netradiční didaktickou pomůcku pro učitele, která usnadní a snad i zefektivní jeho pedagogickou činnost. První část práce se zaměřuje na teoretické aspekty v souvislosti s rozvíjením klíčových kompetencí žáků. Zastávám názor, že efektivní využívání multimédií ve výuce vede k rozvíjení klíčových kompetencí. Druhá část teoreticky pojednává o vzniku a vývoji multimédií a jejich uplatnění a vlivu při rozvíjení klíčových kompetencí žáků. Třetí část obsahuje tvorbu multimediálního produktu a jeho praktické využití ve výuce chemie. Nedílnou součástí diplomové práce je DVD, obsahující multimediální prezentace a soubor digitalizovaných chemických experimentů z oblasti anorganické chemie. Tématicky jsou multimediální prezentace koncipovány pro výuku chemie v základním vzdělávání. V žádném případě se nejedná o profesionální produkt, ale spíše o návrh, jak by taková prezentace mohla vypadat. Snažil jsem se o přehlednost, komplexnost a jednoduchost.

Activating Strategies of Managing Students' Learning Process in Chemistry
Gabriel, Štěpán ; Rusek, Martin (advisor) ; Beneš, Pavel (referee)
TITLE: Activating Strategies of Managing Students' Learning Process in Chemistry AUTHOR: Št pán Gabriel DEPARTMENT: Department of Chemistry and Chemistry Education VEDOUCÍ PRÁCE: PhDr. Martin Rusek ABSTRACT This thesis is focused on literature-search evaluation of modern methods applied in chemistry education. Firstly, the development of chemistry education from the beginnings of the Czech schooling system until present is briefly described. Further, currently the most widely discussed methods used in Science education eventually Chemistry were defined based on the analysis of scientific literature and other available electronic resources. These methods are briefly characterized; an evaluation of the possibility of their usage in teaching practice in terms of Czech schools is made not only with regards to the educational reality in schools, but also with respect to the law (Framework Educational Programmes). KEYWORDS: Chemistry teaching, modern teaching methods, constructivism, project-based learning, inquiry-based learning, STEM, STEAM

Teaching consumer literacy for students of second stage of elementary education on the example of dairy products
Jelínková, Věra ; Marádová, Eva (advisor) ; Beneš, Pavel (referee)
In developed countries, the majority of the population perceives food only from the viewpoint of a consumer. Few know its origin, production technology and composition, and they can't critically evaluate, which products are beneficial in terms of proper nutrition. Therefore, this work deals with the development of consumer literacy in the area of food, i.e. food literacy among pupils of second stage of elementary school, where is not systematic given attention to this theme. As an appropriate example for teaching were chosen milk and dairy products, which are an essential part of healthy eating mostly in childhood. In line with the objectives of this work has been created structured summary of the findings of these foods serving as a theoretical background for teachers. It was also done research survey about knowledge and attitudes to milk and dairy products among pupils of second stage of elementary school. It turned out that in the surveyed sample, most of the pupils consume milk and basic dairy products (butter, cheese, yoghurt), but the consumption of other fermented dairy products is considerably lower. Most respondents considered milk and dairy products beneficial to our health, however they were almost unaware of its production technology and were not interested in their origin and...

Feedback procedures, its options and limits in practical training of future chemistry teachers
Hladíková, Dana ; Beneš, Pavel (advisor) ; Dvořáček, Jiří (referee) ; Bílek, Martin (referee)
Present days mean rapid development of technologies and their use in various spheres of science, research, production etc. This paper shows possibilities of using video technology in teaching during the pedagogical training of future chemistry teachers, with appropriate feedback. Terms reflection and self-reflection of teacher's skills, diagnostics and autodiagnostics of pedagogical activities, monitoring of pedagogical skills etc. represent in fact processes connected with application of feedback principles during the pedagogical training. In practice-oriented parts of teaching preparation, these processes are considered to be substantial to increase the effectiveness. Students' opinions shall also have a significant place in post-inspection procedures. Key words: video technology, feedback processes, reflection, self-reflection, diagnostics, autodiagnostics, monitoring of professional skills, inspection of classes, work practice. 6

Insights about Chemistry Education Gained in the Time of COVID-19
Hamerská, Lucie ; Rusek, Martin (advisor) ; Beneš, Pavel (referee)
This bachelor's thesis deals with the topic of distance learning and its conception by chemistry teachers during the COVID-19 pandemic. The theoretical part briefly characterizes the teacher's concept of teaching and its components, the distance form of teaching, its development, principles and effectiveness. Subsequently, attention is paid to the current situation regarding distance education during a pandemic and there is specific focus on teaching chemistry. The transition to the distance form of education was a great challenge for the teaching of chemistry as a subject, which includes not only theoretical but also practical knowledge. Every teacher took a different approach. The aim of the work is to map and present the approaches of several teachers to distance teaching of chemistry, the conditions for distance teaching, both on the part of teachers and on the part of students, and the experience with teaching concieved in such way. The research survey in the form of an interview was attended by 16 respondents. The questions concerned three main areas, namely the technical implementation of distance learning, pedagogical aspects of teaching and the impact of distance learning on educational content. The statements were analyzed using the open coding method. The findings show that at the level...

The influence of hydration accelerators on cement doped with zinc
Beneš, Pavel ; Šilerová,, Iva (referee) ; Šiler, Pavel (advisor)
Zinc in cement has negative properties mainly due to a significant delay in hydration. This bachelor thesis deals with the study of hydration of cements containing zinc. The course of cement hydration was monitored by isoperibolic calorimetry. Zinc was doped to CEM I 42.5 R in the form of 1 weight percent zinc oxide. Calcium oxide, formic acid and calcium formate were used in various proportions as accelerators. The obtained results were compared with the measured strengths and finally the suitability of the given accelerators was discussed for use in construction application.
