Research on Strategies Students Use when Solving Problem Tasks
Koreneková, Kateřina ; Rusek, Martin (advisor) ; Bílek, Martin (referee)
The subject of this thesis is the identification of strategies, which are used by lower-secondary school students when solving problem tasks in chemistry. The strategies were identified during talks with ninth-grade students. The talks conducted by using the Think-aloud method were connected with solution of selected problem tasks. The ascertained strategies were classified as expansive strategies (such strategy can be used to solve more types of problems) and limiting strategies (such strategy can be used to solve easy task, but they can fail when solving more difficult tasks). Furthermore, reader's strategies, which help students to understand the tasks were separately identified. Also, other problems that students had to face when solving the tasks were identified. To identify problematic elements a collection of problem tasks named Metodické komentáře a úlohy ke standardům pro základní vzdělávání - chemie (Methodical comments and tasks for educational standards for elementary education - chemistry) were used. The results showed that when students solved the tasks, which were larger and more difficult, they often used reading strategies, which consist in multiple reading and reading aloud. Some of the expansive strategies the students used consisted in analogous deducing and logical reasoning....

Didactical Equipment of Czech Elementary School Chemistry Textbooks
Šubová, Šárka ; Rusek, Martin (advisor) ; Bílek, Martin (referee)
This thesis deals with the comparison of didactical equipment of Chemistry Textbooks for Basic Schools in the Czech Republic. The first part of the thesis is dedicated to the theory of textbooks and their research within it. The next part, which includes comparison of the textbooks, is pursued by the author from the perspective of two methods: the first being The Degree of Didactical Equipment and the second one The Determination of Didactical Criterion. According to the results of this thesis, the Chemistry Textbooks for Basic Schools in the Czech Republic are alike in its didactical equipment. There are similar structural components in each analysed textbook. There were found only small differences between the best didactically equipped textbooks (the textbooks of the publishers Nová škola and Fraus) and those with the lowest outcome (the textbooks of the publisher Taktik), although the time period between publishing the newest and the oldest textbook is more than 25 years. Due to homogeneity of the results and therefore lower possibility of comparing textbooks the method of the Determination of Didactical Criterion was applied. The method does not offer the final account of the most suitable textbook for school education but it presents different view of analysed textbooks, for example the...

Interactive Tools in Chemistry Education
Helceletová, Zuzana ; Čapek Adamec, Martin (advisor) ; Rusek, Martin (referee)
Information and Communication technologies (further only "ICT") are becoming an essential part of the society, of its structure and functions and impact the lives of individuals. Integration of ICT into education together with a change in the traditional education system into a modern one is therefore seen as an important factor of further development. The paper deals with some of the options of how to utilize electronic support for teaching chemistry at secondary schools. It is mainly the visualisation of the subject matter, proper positive motivation of students and their activation. The paper describes in detail presentation of chemistry using specialized computer software and visualisation of chemical processes. One of the goals of this paper is to present different software for teaching support and to compare them with regards to functionality, user-friendliness and possibilities of other application. Among the selected software there are: ACD/Chemsketch, Isis/Draw, WebLab Viewer Lite, Orbitel Viewer, ArgusLab, Anorganicka chemie, ChemDraw, ChemLab, Basic Chemi and LM Chemie. The significant part of the paper is dedicated to Wolfram Mathematica software, summarizing the essential information about the author, distributor, different versions of the software and their possible utilization....

The Use of Eye-tracking for Analysing the Strategies Students Use when Solving Chemistry Problem Tasks
Tóthová, Martina ; Rusek, Martin (advisor) ; Bílek, Martin (referee)
In the thesis, results of a research focused on monitoring strategies used by students during problem solving are presented. It follows previous studies conducted with the use of think- aloud method. Due to limitations of this method, an eye-camera is used. The record of the camera is used not only to analyse student's problem-solving process, but also as a tool eliminating one of the RTA limits - inaccuracies due to forgetting. The strategies were investigated among economics-oriented vocational school students in the first grade. They solved indicator tasks from the Methodical Comments and Tasks for Educational Standards in Lower-Secondary Education. The research sample was selected based on a pre-test composed of the selected tasks. According to the results, the students were divided into four categories, two students of each category were selected for the research. They solved a second set of the tasks. Based on eye-tracking and think-aloud data, their problem- solving processes were mapped and false-positive results were eliminated. The research results show that the students used the most expansive strategies, mainly work with the periodical table. However, in most cases, these strategies did not lead to a correct solution, due to the students' problems during solving. In these cases, they...

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

Lower-secondary School Chemistry Textbooks: The Use and Selected Structural components' Analysis
Vojíř, Karel ; Rusek, Martin (advisor) ; Klečková, Marta (referee) ; Kmeťová, Jarmila (referee)
Textbooks are a tool which serves several purposes in education. Except for students, textbooks are also being used by teachers who, thanks to a complex selection and transformation of the subject-matter, represent the most concrete shape of intended curriculum. For this reason, textbooks can influence education significantly. However, this field has not been addressed yet within lower-secondary school chemistry education research. The goal of this thesis was therefore to map the field of Czech lower-secondary school chemistry textbooks. In order to put the topic into a context, first, a systematic literature review on science education textbook research was performed. Also, textbooks' publishing after 1989 in the context of national lower-secondary school curricular changes was mapped. Textbooks' potential influence is conditioned by their elaboration as well as their use. For this reason, a questionnaire survey was performed on a random sample of 378 chemistry teachers from 370 lower-secondary schools. This sample enables generalization for the entire lower-secondary schools and chemistry teachers' population in Czechia. The research showed: which textbooks are being used, the way they were selected at schools, teachers' evaluation, and purpose of their use with a special attention to particular...
