Chemistry experiments' potential to develop vocational students' scientific literacy: An analysis of selected materials
Horníková, Marcela ; Rusek, Martin (advisor) ; Vojíř, Karel (referee)
This thesis is focused on analysing chemical experiments and their potential to help increase science literacy among vocational school students. Currently, greater emphasis is placed on the development of scientific and critical thinking at higher cognitive levels and science literacy. These skills and abilities can be achieved through tuition based on experimental scientific activities. For this reason, the main goal of this thesis was to review the quantity and method of processing of individual experiments in terms of quality and compliance with the given requirements. Experiments in the field of organic chemistry were taken from available vocational school literature and were analysed and evaluated. These sources were the following textbooks: Chemie pro střední školy, Chemie pro studijní obory SOŠ a SOU nechemického zaměření and the web page Studium chemie and the video database of chemistry experiments. Each experiment was evaluated whether it met the analysed criteria of transparency, connection with practical life, problem solving and material, technical, time and economic simplicity. Furthermore, the experiments were evaluated in terms of usability during various stages of tuition with regard to the development of students through different levels of inquiry. The last and main evaluation...
Activating methods in education of topic carbohydrates
Kyzlíková, Iva ; Vojíř, Karel (advisor) ; Bílek, Martin (referee)
Activation methods in teaching are nowadays often discussed complementary teaching to classical teaching. Within these methods, emphasis is placed on activating the student, ie on encouraging his interest in the implementation of the activity, but at the same time there is an advantageous opportunity for teachers to influence and specify specific goals to meet the requirements of FEP and SEP. One of the aims of the work was to map the issue of activation methods with a focus on project teaching and research-oriented teaching and to compile a selection of topics for activities that use activation methods with a focus on the topic of carbohydrates in the form of research. Another goal of this work was to design a teaching activity using activation methods on the topic of carbohydrates (a topic in organic chemistry, which is relatively more demanding for students, but no less important) and to verify this activity in a pilot. The design of the activation method with aspects of the project teaching "Getting acquainted with carbohydrates" was actually verified in the 9th grade of Vilémov Elementary School in 2021, within the subject Chemistry. Pupils worked on the activity in groups and the result was five solutions of the activity (projects), of which there were four presentations and one poster....
Elaboration of Learning Problem-Tasks from the Field of Chemistry
Vojíř, Karel
This thesis deals with the elaboration of learning problem-tasks related to the Standards for elementary education in the field of Chemistry. The author of this thesis worked on this topic within a project under National Institute for Education. The starting point for creating the tasks, illustrating and concretely expounding the Standards is the concept of science literacy. In this principle in chemistry instruction a broader context and a transfer to everyday life are applied. Learning tasks were created on the base of: science literacy and the results of Czech pupils in its testing, context of standards in Czech curricular system, elements of problem-based learning, types of learning tasks and cognitive parameters. During the elaboration of the tasks a pilot testing of selected learning tasks was realized. The results of the pilot testing were used in further designing more problem-tasks to cover one expected outcome in every topic of Chemistry within the elementary school curriculum. According to the methodology described in this thesis, a material named Methodical comments and tasks to the standards for primary education - Chemistry was created. This material contains a coherent set of learning problem-tasks illustrating two- thirds of the indicators from the standards for elementary education...
Evaluating Difficulty of Chemistry Textbooks for Vocational Schools
Vosyková, Lucie ; Rusek, Martin (advisor) ; Vojíř, Karel (referee)
TITLE: Evaluation of the text difficulty of chemistry textbooks for secondary vocational schools AUTHOR: Lucie Vosyková DEPARTMENT: Katedra chemie a didaktiky chemie SUPERVISOR: PhDr. Martin Rusek, Ph.D. ABSTRACT: This thesis builds on previous researches of textbooks for primary, secondary and grammar schools and focuses on the analysis of the text difficulty of chemistry textbooks for secondary vocational schools of non-chemical focus. The aim of this work is to analyse the text difficulty of chemistry textbooks for non-chemical high schools, using the Nestlerova-Prucha-Pluskal method, to compare the text difficulty of chemistry textbooks for non-chemical high schools with primary and secondary school textbooks,and last but not least, to compare the text difficulty of particular chapters of choosen textbooks for primary and secondary schools. The results of the analysis are intended to provide teachers seeking support for their teaching with a possible criteria for a textbook selection. Based on the findings, the five analyzed series of textbooks can be divided into two groups. The first group consists of textbooks published by Scientia and Fortuna, whose text difficulty is at an appropriate level with a lower rate of technical terms. The other group consists of two textbooks published by SPN and...
Knowledge and Opinions of Students on Genetically Modified Organisms
Semencová, Barbora ; Hlaváčová, Lucie (advisor) ; Vojíř, Karel (referee)
This diploma thesis is focused on topic of genetically modified organisms and their use in the practical sectors of human life. Theoretical part of the thesis defines general terms GMO, plasmid, genetic engineering, biotechnology. It also records historical milestones relating to the problematic, deals with individual techniques of genetic engineering and briefly states legislative procedures in context of dealing with GMO. It gives examples of transgenic organisms and summarizes advantages and disadvantages of their use.Practical part of the thesis contains educational program called "Genetically modified organisms", which was conceived by the author and includes a draft of a lesson inclusive of teaching materials - powerpoint presentations, worksheets, interactive worksheets, auxiliary text for teacher and written preparation. Research part deals with high school students change of view about using GMOs after completing the educational program. Due to analysis was proven that most of the attitudes and knowledge about GMO was changed after completing the educational program (for example in issues of willingness to consume GM food and animal products, perception of advantages and disadvantages etc.) Data was still unchanged in questions which cannot be affected by the program (control of food packaging or...
