Sensory analysis as a means to increased transparency of analytical methods used in practical chemistry education
Kocichová, Kristýna ; Rusek, Martin (advisor) ; Kolář, Karel (referee)
The theoretical part of the thesis is focused on the description of sensory analysis, its history, basic methods, principles, and procedures in the analysis of solutions. It specializes in three basic tastes: salty, sour and bitter. It then focuses on explaining the basic analytical methods whose applications can be found in practical chemistry teaching, in particular an introduction to the principles of conductometry, spectrophotometry and potentiometry. It then addresses the issues of science teaching, language and the difficulty to learn these sciences. The aim of this bachelor thesis was an attempt to increase the transparency of analytical methods in practical chemistry teaching through sensory analysis methods. Building on previous work addressing this issue, further experimental activities were designed and piloted. These activities give the possibility to increase first of all the interest and motivation of the students in chemistry, then to lead the students to think on their own, to find new solutions, to be able to work with the instruments within the analytical methods and to verify and compare the results of the measurements. The activities have been validated on chemistry teacher education students and are included in the practical part divided into sensory and instrumental parts. The...

Design and verification of an inquiry-based task on the topic of acids and hydroxides for elementary school students
Tomešová, Jana ; Chroustová, Kateřina (advisor) ; Rusek, Martin (referee)
This thesis looks into inquiry-based learning in chemistry classes at elementary schools. The objective was to design an inquiry-oriented task on the topic of acids and bases which would comply with the goals of inquiry-based science education while at the same time achieving the compulsory outputs of this topic, as defined by The National Curriculum. The theoretical part of the thesis focuses on the characteristics of teaching chemistry in primary schools and the definition of inquiry-based learning specifics. The practical part firstly describes the exact course of the proposed task. Subsequently, the results obtained in cooperation with eighth-grade students are verified and assessed. To evaluate the task, several materials were used: the outputs created by the pupils during the activities, the initial and final knowledge tests, and IMI (Intrinsic Motivation Inventory) questionnaires which focus on the students' perception of the task. Based on the obtained data, the task was evaluated from several points of view. The implementation of the task successfully led students to learn about concepts related to the topic, as well as various methods of pH measurement. The effect on their skills for planning and carrying out a chemical experiment was also positive. The shortcomings of the task, as...

History of Chemistry Production in the Czech Republic Territory
Grassinger, Tomáš ; Rusek, Martin (advisor) ; Kolář, Karel (referee)
This thesis deals with the chemical production and its history in the Czech Republic. The chemical production has its long tradition in the Czech Republic. In the first chapter the thesis focuses on the topic of the chemical production in the national curriculum and selected school curriculums in the Chrudim region and the Pardubice region. In the second chapter it analyses the production of various chemicals described in the present and former elementary school textbooks of Chemistry. It also concerns historical Chemistry textbooks published since the year 1945 in which other facts that are not being included in the present textbooks are mentioned and enlarge the synthesis. The history of the notable and traditional chemical production in the Czech Republic is the component of this thesis in the third chapter. This thesis summarizes all the facts concerning the chemical production so that it could be used by teachers and students who are interested in studying the subject of Chemistry. KEYWORDS chemical production, history of chemicals, national curriculum, school curriculum, textbooks for elementary schools

Evaluation of lower-secondary chemistry textbooks' visual representations in the topics of acids, bases and neutralisation
Krumlová, Eliška ; Rusek, Martin (advisor) ; Bílek, Martin (referee)
The bachelor thesis is focused on the analysis of visual components used in chemistry textbooks for lower-secondary schools in the Czech Republic in the topic of acids, bases and neutralization. In the first part, attention is paid to the theory of textbooks, their development, research and the triple representation of visuals in the natural sciences. The following sections describe the objectives, methods and results of the thesis. The aim was to analyse the visual components used in the topic of acids, bases and neutralization in chemistry textbooks for the eighth grade of lower-secondary school. Furthermore, the aim of this thesis was to compare textbooks based on the total number of representation of individual components (quantity and proportions). The performed analysis complements the current overview of the representation of visual components. It was found that Fraus publishing house textbooks have the most represented images in the analysed topic, and on the other hand Nová škola textbooks include the least representation. The analysis further showed that most textbooks contain no sub-micro representations on acids, bases and neutralization. This representation can be found only in the textbooks published by Fraus and in the textbook Hravá chemie (Playful chemistry) published by Taktik....

Constructivism in Organic Chemistry Nomenclature Education
Musilová, Lucie ; Rusek, Martin (advisor) ; Kotoučová, Hana (referee)
Organic chemistry nomenklature is one of the most importatnt matter of chemistry education. Its last change occured in 1993. The available high school chemistry textbooks, which have been analized, deal with nomenclature very briefly. They use the instructive educational approach which is mostly based on deduction. However, it is contrary to the contemporary attitude of education. This is the substantiation for creating the alternative procedure and verifying the availability in practice. This work presents two worksheets that deal with the introduction of the organic chemistry nomenclature. This is the substantiation of creating the alternative procedure and verifying the availability practice. This metodology has been assesed by teachers of grammar schools. Due to the reactions, the material was positively evaluated not only by students but also by teachers themselves. Remarks acquired by piloting were incorporated into the material and can therefore be tested on a larger representative sample.

Issue of creating school curriculum
Rozkydalová, Andrea ; Rusek, Martin (advisor) ; Čapek Adamec, Martin (referee)
1 ABSTRACT: This bachelor's work covers the issue of creating school curriculum (SC). The theoretical part proceeds from the system of curriculum documents and methodology of creating SC. The next part of this work deals with analysis of seven different SC, specifically the part People and nature and Educational subject Chemistry and analysis of characteristics of Educational subject Chemistry. Sample of analysed schools consists of seven elementary schools. With connection to creating SC the next part focuses on articles that deal with this issue in specialist magazines and teachers' opinions about implementing SC into schools. It also includes dialogs with teachers that created SC for their schools. Advantages and disadvantages of implementing SC into schools emerge from these dialogues as well as valuable advices about creating the documents themselves. The conclusion of this work was creation SC for Educational subject Chemistry that is going to be used as a sample for teaching since school year 2014/2015.

Assessing the parameters of quality of chemistry education
Rozkydalová, Andrea ; Rusek, Martin (advisor) ; Beneš, Pavel (referee)
The main scope of this thesis was assessing and evaluation of parameters of quality of chemistry education at secondary and primary schools. In this thesis, there are views at education quality in general connected to the natural science education and specifically chemistry. Then the attention is being paid to the system of curricular documents and standards. Then there are written procedures, description of progress and results evaluation. In this thesis, an evaluation tool was verified during a pilot verification at secondary and elementary schools. A part of this thesis is dedicated to evaluation of individual lessons with the use of evaluation tool. Other possible factors which influence teachers' activity and education quality itself.
