Administrative building
Smejkal, Petr ; Spáčilová, Jitka (referee) ; Sedláková, Markéta (advisor)
The subject of the diploma thesis is the elaboration of the project documentation of an administrative building in the south-eastern part of Brno. The building has seven above-ground floors, of which five above-ground floors will be used as office space, one above-ground floor will be used for commercial use and gastronomy. On the last floor, there will be an elevator lift range and a technical background for air conditioning. The support system is designed as a reinforced concrete skeleton based on a reinforced concrete slab and pilots. The façade is designed as lightly ventilated with facing bricks. For this object, a single-shell roof area is selected.

Solid fuels boilers
Šmejkal, Petr ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with burning solid fuels in boilers used for house heating. In the first chapter, the individual kinds of solid fuels are described in light of their composition, properties, means of their energetical application and ways of adjusting them to a form proper for combustion. In the second chapter, the individual types of solid fuels boilers are described. The last chapter deals with comparision of several specific boilers in light of their purchase price and operating expenses.

Applications for Wearable Devices based on Android Wear OS
Šmejkal, Petr ; Zeman, Kryštof (referee) ; Hošek, Jiří (advisor)
The semestral project "Application for Android Wear wearables” describes basic principles of the communication network - M2M (machine to machine), H2H (human to human) and D2D (device to device). It is also focused on wearables especially smart watches, available operation systems for smart watches and system Android, Android Wear. In the practical part is described functionality, design and structure of developed application for Android wear smartwatch.

Eye-tracking as a method for monitoring students' strategies when working with the periodic table of elements
Kopecký, Adam ; Šmejkal, Petr (advisor) ; Míka, Luděk (referee)
Teaching methods try to improve every year, and modern technologies help this progress. One of these technologies is the eye-tracking method. This method allows capturing certain procedures of the respondents from their eye movements. We can subsequently derive certain specific strategies from the procedures, and subsequently adapt the teaching materials to themThe thesis focuses on the detection of different strategies of pupils when working with the periodic table with the help of an eye-tracking device. The work uses a pre-prepared test in which the students determined the specific location of specific elements in a table with displayed element symbols and proton numbers and subsequently the location of other specific elements in a blind periodic table. Subsequently, the strategy of pupils with higher self-confidence was examined and compared with the strategy of pupils with lower self-confidence. Success in finding individual elements in the test was also compared. A typical strategy, which was observed in most respondents, is to determine the location where the element is most likely to be located and then search in a sufficient area for signs that could belong to the searched element. This fact does not apply only in the case of the search for the element antimony, which the respondents could...

Creation of material for chemistry teaching in virtual reality
Málek, Albert ; Míka, Luděk (advisor) ; Šmejkal, Petr (referee)
Modern education is developing dynamically along with new technologies. One of the main aspects of this development has been the massive expansion of the consumption of online video content, especially on social networks. Another and similarly major influence may be virtual reality (VR) in the near future. This thesis combines both of these aspects and sets as one of its goals the creation of an educational VR video available on the social network YouTube. The theoretical part of the thesis first describes aspects of the use of VR and video not only in chemistry education. It also summarizes the existing knowledge about what a good educational VR video should look like. This knowledge then served as a basis for the search of available educational VR videos and for its actual production. In less than six minutes, the video produced as part of this work introduces the viewer to the workings of the global carbon cycle and its connection to climate change. Working in the 3D modelling program Blender was essential to the creation of the video, which allowed for the inclusion of more sophisticated visual elements. The video was tested with 15 respondents, aged secondary and primary school students, who, after watching it, completed a knowledge test to check the transfer and understanding of the...

Selected materials for teaching chemistry in lower grades at the eight-year grammar school
Wilhelm, Lukáš ; Šmejkal, Petr (advisor) ; Janoušková, Svatava (referee)
The incoherence of the Czech school system, which is based on the existence of three different types of grammar schools, results in a time inconsistency in the teaching of some subjects. Today, pupils at eight-year grammar schools encounter the subject of chemistry for the first time one to two years earlier than pupils at primary schools. However, the same textbook may be presented to both groups, but it may be inappropriate for younger pupils as it would not reflect the fact that they are not cognitively advanced enough. How do eight-year grammar schools themselves approach this disparity? Does the approach to teaching chemistry to younger pupils differ in foreign countries in any way? These are the questions this thesis seeks to answer. To find the answers, an analysis of Czech and selected foreign curriculum documents was used. The most important results of this thesis include the fact that eight-year grammar schools in the Czech Republic most often include a total of seven teaching units during the first year of chemistry teaching, of which the most abstract concepts are included in the teaching unit Particle composition of substances. In foreign countries, the teaching of chemistry to younger pupils does not go as in-depth as in our eight-year grammar schools, but comparable topics are...

USB-microscope in chemistry and geology - a toy for geeks or a teaching aid?
Kopecký, Ondřej ; Šmejkal, Petr (advisor) ; Martínek, Václav (referee)
Microscopes are often used in school environments to give students insight into the microworld, whether (especially) to observe small objects in biology, but also in chemistry or geology. A stereoscopic microscope, in other words a binocular, is usually used to observe opaque objects. These devices make it possible to examine larger, opaque and three-dimensional samples. In recent decades, the so-called USB-microscope has appeared on the market and in technical fields, which could be an alternative to binoculars due to its properties such as durability and small device dimensions. However, these devices are not widely used in teaching yet, but the question is whether their use would not cause difficulties or be less illustrative for teaching, eg due to the limited field of view of the USB-microscope compared to binolup. In this regard, the work deals with the observation of binoculars and USB-microscope in terms of motivation of students in working with the device and also tries to evaluate the user experience of students in working with these devices. For this purpose, a teaching activity was prepared for working with a binolup and a USB-microscope, in which students used a binolup and a USB-microscope to determine the crystallographic system, their chemical composition and the associated shape of...
