Interdisciplinary Access to Teaching Science at Vocational Schools with Nonchemical Specialization
Kuželová, Nikola ; Rusek, Martin (advisor) ; Beneš, Pavel (referee)
Implementation of school educational programmes brought many changes, particularly at secondary schools in the Czech Republic. One of them is the inclusion of education into the field of natural sciences in many fields of secondary vocational schools, where it was previously missing. This brought some specifics and problems. Some schools are coping with the current situation by implementing an integrated science course. A part of this bachelor thesis is focused on the current state of science teaching in the Czech Republic. The main contribution of this thesis are the results of the content analysis of educational programmes at schools, where the integrated science course is taught. Special attention was paid to the actual implementation of the course, number of hours, general objectives and educational strategies. Another part of this thesis contains the results of a research on teachers' approach to teaching chemistry at secondary vocational schools and the results of a structured interview with a teacher of the integrated science course. The approach to the integration of science courses and teachers' attitudes towards this concept of teaching is evaluated as well.

TITLE: New possibilities of providing basic natural science education through experiments AUTHOR: Mgr. Veronika Köhlerová DEPARTMENT: Department of Chemistry and Chemistry Education SUPERVISOR: Prof. RNDr. Pavel Beneš, CSc. ABSTRACT: The thesis stems from the basic need to support and develop natural science education. Based on didactic, technical-economic and ergonomic requirements, a teaching tools kit has been created, which facilitates 100 natural science experiments. The kit includes a methodological manual; further methodological support is also provided on the webpage of the kit's manufacturer. To complement the kit, a concept of an optional teacher training course Natural Science Experiments for Preschools and Primary Schools has been created. The course will take place at the Pedagogical Faculty of Charles University in the school year 2013/2014. During the course of the thesis, didactic research methods were used to choose, process, test, organize, and optimise educational experiments. The pedagogical methods used included questionnaires and expert testimonials. The thesis provides a substantial response to the current educational needs in the field of natural science pre-literacy already at preschools and natural science literacy at primary schools.

Rusek, Martin ; Beneš, Pavel (advisor) ; Bílek, Martin (referee) ; Škoda, Jiří (referee)
TITLE: Students' Attitudes Towards Chemistry According to the Secondary School They Attend AUTHOR: PhDr. Martin Rusek DEPARTMENT: Katedra chemie a didaktiky chemie SUPERVISOR: prof. RNDr. Pavel Beneš, CSc. ABSTRACT: The research presented in this thesis completes the data with the information about so far neglected vocational schools students' attitudes towards chemistry. After the curricular reform, impact put on general education, including chemistry, brings considerable changes in this area. The questionnaire used was focused on three spheres: students' attitudes towards chemistry, didactical facilities used in chemistry education and students' attitudes towards particular chemical topics. The questionnaire was submitted to students (N = 959) at the beginning of the school year after they entered secondary school. That way the results reflect students' attitudes constructed at primary schools. The results show negative students' attitudes. They are mostly affected by the difficulty of the subject and also by students' low interest in the topics. It was also proved that topics close to students' lives play a vital role. Based on the results of the research, proposals may be word in order to solve the situation: emphasizing activating methods such as: experimental work and active observation, also...

Innovations of Education Content and Methods in Teaching Chemistry Focusing on ICT-supported Visualization
Adamec, Martin ; Beneš, Pavel (advisor) ; Bílek, Martin (referee) ; Šmejkal, Petr (referee)
The use of information and communication technologies, including computer graphics, in teaching chemistry is one of the frequent issues of contemporary chemistry didactics. Current publications are mainly focused on displaying structure of chemical compounds and symbolic form of chemical reactions. This thesis offers a more complex view on the computer graphics and other means of information and communication technologies - their possibilities and limits of use in teaching. The goal of the thesis is to provide an overview of selected computer-graphics technologies and to discuss their role during current curricular reform, based on current problems identified by students attending chemistry-teacher training courses and chemistry teachers. Usability of selected elements in pre-teaching and teaching phases was checked. Innovations of contemporary teaching methods were proposed using computer graphics. The thesis is focused on the area of visualization of educational content with use of computer graphics, computer-assisted innovation of methods and educational content, computer games and the role of computer graphics in didactic transformation. Two textbooks for lower-secondary and upper-secondary schools were created. These textbooks contain newly developed parts using computer graphics. According to...

TITLE: Substances present in every day life representing threats to the health of older- shool-age children AUTHOR: Iva Metelková DEPARTMENT: Department of Education SUPERVISOR: PaedDr. Eva Marádová, CSc. ABSTRACT This thesis deals with the substances present in everyday life, which may pose risk for human health. In the theoretical part of this work groups of hazardous substances are characterized. For selected representatives of each group are specified. negative impacts on human health and outlines the mechanisms of action. Individual chapter is devoted to physical and psycho-social development of school age students using knowledge of developmental psychology. Substances which on the other way help detoxify the body and help it to be resistant to the effects of potentially hazardous substances are also mentioned. The aim is to map the practical awareness of the hazardous effects of selected substances among pupils attending upper primary school. Questionnaire survey found that students do not attach danger arising from the presence of potentially hazardous substances in foods, cosmeticsand household. Therefore I recommend pay attention to information about risks arising from long term exposure to these substances. KEY WORDS: harmful substance, health protection, food hazards, drugs
