Kratom as a candidate for a new topic in chemical education
Vacková, Kateřina ; Rusek, Martin (advisor) ; Kuhnová, Marta (referee)
The bachelor thesis aims to raise awareness of interested parties about the psychoactive substance kratom and to highlight the issue of kratom in today's society. It places the substance in a historical context and describes its different varieties together with its chemical content, phytochemistry, preparation, and use. The work also aims to outline the issue of kratom in terms of its addictive potential, legislation and places the issue in a school environment. Through two case studies, using data collection methods in the form of semi-structured interview, survey, and data analysis, specific situations of kratom use by school students, the approach of teachers together with the chosen solution, and the students' and teachers' attitudes towards the issue at hand are described. The whole work then sets the basis for a possible introduction of the kratom topic into chemistry lessons, for example through chemistry textbooks. The data obtained confirmed the increasing incidence of kratom use by secondary school students and the existence of kratom as one of the current topics among the young generation. The results show a majority interest of teachers and students in further education in this area and in the possible integration of the kratom topic in the classroom. The case studies also indicated a...

Analysis and comparison of elementary school educational programs in the Czech Republic based on the findings of the Czech School Inspectorate survey
Medek, Petr ; Rusek, Martin (advisor) ; Tóthová, Martina (referee)
This thesis presents research on primary schools in the Czech Republic, selected according to whether they were included in the Thematic report of the Czech School Inspectorate in 2023. The thesis focuses on the results of this report for the educational field of Chemistry. Within the theoretical part, the gradual development of curriculum documents in the Czech Republic is elaborated with regard to the currently ongoing revision of the RVP ZV. In the practical part, an analysis of the school curriculum of the given schools is worked, focusing on the distribution of the number of teaching hours in the educational field of Chemistry within the educational field of Human and Nature, as well as an analysis of the distribution of available hours in the educational fields. An analysis of the amount of active verbs in the expected outcomes and whether primary schools have included teaching methods in their school curriculum is also made. The final section shows, among other things, that the highest number of available hours is devoted to the educational area of Human and Nature (median of 6 teaching hours), that the teaching of the educational area of Chemistry still persists under the title of Chemistry in the eighth and ninth grades with two teaching hours each, and that the highest number of teaching...

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...

Teaching chemistry at high school - experimental part, proposals of chemical experiments suitable for chemical education at high school
Boguschová, Veronika ; Petrželová, Simona (advisor) ; Martínek, Václav (referee)
The experiment is an integral part of chemistry education. The use of food and natural materials effectively connects chemistry learning with everyday life. Suitable foods for this purpose are, for example, lentil-shaped candies (lentils). There are lentils from many manufacturers on the market, differing in the types of dyes used. The dyes used are both natural and synthetic. The diverse properties of these dyes allow the use of lentils for teaching different topics in chemistry. Lentils coloured with natural dyes can be used for laboratory exercises focusing on pH and acid-base indicators. In combination with experiments with extracts from natural materials, they can also be used to teach qualitative analysis and UV-VIS spectroscopy. In the diploma thesis, two laboratory exercises were designed on the analysis of dyes used in the food industry, which were later validated on secondary school students Synthetic dyes often differ in their polarity, which can be used in laboratory exercises focused on separation methods, specifically in this work for teaching chromatography and extraction. For these purposes yellow, green and blue synthetically coloured lentils are used. Proposed laboratory exercise has also been validated with secondary school students. Methodological guidelines were written for the...

The use of eye-tracking in chemistry didactics research
Tóthová, Martina ; Rusek, Martin (advisor) ; Popelka, Stanislav (referee) ; Doulík, Pavel (referee)
This dissertation thesis is an annotated collection of academic texts and summarizes the author's contributions to research on the use of eye-tracking and problem solving in the context of science education. The thesis responds to the growing use of eye-tracking in education and provides a systematic review of the current state of knowledge. Primary research has focused on chemical problem solving by upper-secondary school students. Using eye-tracking and think-aloud, the students' solving process was analyzed. The results showed that the observed students had low ability to solve these problems and often relied on limiting strategies such as guessing. Based on the problems identified, an action research intervention was designed. Regular inclusion of tasks, progressive learning and formative feedback led to improvements in pupils' abilities. The problem-solving ability of prospective chemistry teachers was tested in a similar manner. In addition to eye-tracking and think-alouds, a semi-structured interview was included in the research. It showed that there are significant problems in problem solving for prospective chemistry teachers, especially understanding the assignment. The dissertation thesis summarizes the contributions of the articles and proposes solutions to improve the current situation.

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...
