PhD. Thesis are structured into two parts - first is comparison of effect of 4 seeds (amaranth, rapeseeds, sunflowerseeds and linseeds) on parametres of rumen fermentation and composition of fatty acids. Seeds were modified by milling, grinding or microwave heating.Findings of their effect on rumen fermentation were compared by control diet without seeds. The second part was specialised on effect of different amount of concentrate and forage in diet on fermentation parametres and amount of fatty acids. Diets were composed by barley and hay and then 3 diets for lactating cows were observed. Experiments were made on RUSITEC, which was apparature simulating environment in rumen of ruminants.

i Title: Support for the Implementation and Explanation of Problematic Physics Experiments in Education at Primary School - Mini Case Study Author: Bc. Aneta Čermáková Department: Department of Physics Education Supervisor: RNDr. Jitka Houfková, Ph.D., Department of Physics Education Abstract: This thesis aim is to refer and to acquaint with the problem of experiment in natural sciences at primary school. It identifies the obstacles encountered by primary school teachers when they use experiments in the education and it formulates principles that should guide authors of future materials dealing with experiments for primary school to make it easier for teachers to use them in education. After the introduction dealing with the experiment in the curriculum and textbooks for primary education, interviews with 8 primary school teachers follow. Based on the interviews, a material containing 15 descriptions of experiments for primary school was prepared. It is the next part of the work. This is followed by the outputs from the involved teachers' feedback on the basis of which the material was modified and the conclusions and recommendations for other similar materials were formulated. A CD with the thesis text in digital form, recordings of interviews with teachers, photos and videos illustrating the experiments...

The aim of this diploma thesis is to introduce wayshow teachers can make their elementary school pupils more perceptive to learning physics by the means of specific methods. The thesis first examines on howthe subject is perceived by pupils. It later inquires whether the usage of physical experiments changes how they feel about physics. Initially, the work makes use of an Intrinsic Motivation Inventory (IMI) questionnaire. The collected information is later compared and hypotheses are made. Next, the thesis describes how the structural dialogue with elementary school pupils was prepared and subsequently executed to prove the hypotheses. The questionnaire results put a base to the final conclusions and suggestions which can be applied in a classroom.

Animals as Laboratory Objects: Analysis of the Power Discourse PhDr. Tereza Vandrovcová Abstract This dissertation thesis encompasses a critical discourse analysis of the power correlates of expert knowledge and other factors that can hinder the open and unbiased discussion concerning the ethical aspects of the use of nonhuman animals in biomedical experiments. A brief history of "the animal" is first provided before the issue is positioned within the theoretical framework of Animal Studies. The fourth chapter is composed of an overview of the most frequent arguments both for and against the use of animals in biomedicine. The author draws upon her research as she analyzes scientific texts to reveal how laboratory animals are socially constructed as scientific objects and subsequently describes the effects this has on the perception of their moral value. A series of semi-structured interviews with critics and advocates of animal experimentation, such as animal rights activists and laboratory workers who conduct experiments on animals, is the pivotal section of the paper. It is established that lab workers in the sample are convinced of the necessity and legitimacy of current practices, that lab workers have a tendency to suppress animals' individuality when describing their work, that lab workers deem their...

The thesis deals with molecular gastronomy as an expanding culinary direction and is focused on the use in chemistry teaching in primary and secondary education. There are described home experiments which were verified, documented and explained.

This thesis deals with the incorporation into teaching physics at the elementary school. It highlights the importance of conducting experiments on this subject. It deals with the role of improvised devices in physics education and their active use of the students. Examines and compares the benefits of active participation of pupils in the classroom for their motivation and better understanding and reinforce the learning.

The Diploma Thesis is focused on the effect of the preparation Terra-Sorb which contains free amino acids, on the yield and the quality of choosen field crops. The main attention is pursued especially on the use of nitrogen and aminoacids in the plant nutrition. It's analyzed mainly in the literature review which is also focused on the intake of the nutrient and foliar nutriet of the field crops. The practical part is focused mainly on the verification of the effect of the stimulator Terra-Sorb. It's effect was verified during annual and perennial small plot trials on the location in Velká Bystřice. There were verified the different applications of the stimulator Terra-Sorb in the winter wheat, sugar beet and spring barley. There were evaluated yield and quality of each crops.

The aim of this diploma thesis is to create an educational portal designed to support the teaching of physics at the elementary school with the use of standard web design methods. The purpose of the portal will be to simplify the preparation of teachers for experimental teaching at the 2nd level of elementary schools through a database of experiments and other materials such as videos. The benets of this portal will be veried and evaluated through in-depth interviews with physics teachers at the 2nd grade of elementary schools. One part of the thesis is also an analysis and evaluation of similar web projects dealing with physics teaching. In the rst part of my thesis, I deal with the analysis and evaluation of similar web projects. The next part is focused on the design and creation of the educational portal itself and contains brief information about the design methods and the procedures of creation. In the next section, I will deal with the creation of content for the portal and nally, I will interview the teachers who used the created educational web.

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. KEYWORDS: science experiment, natural science...

The presented diploma thesis has an educational character and tries to find a way how to teach geology more attractive at primary schools. It includes authorial proposals for field trip routes and school experiments that can be implemented in lessons or within other educational school activity during school year. The field trips are built to be carried out in the geological park of Bohemian Paradise because of its natural wealth giving many possibilities to be used in teaching geology and other related fields of natural sciences. The experiments are designed to be realized during school lessons, therefore they are meant to be as little as possible time consuming and also the necessary material is supposed to be easily available. A theoretical part of the diploma thesis contains a summary of available natural datasets about the geological park of Bohemian Paradise, a review of the educational principles for organising of the field trips, creating worksheets, experiments and games in teaching process. The principles of creating concept maps are also included. An integral part of the thesis is authorial research with students and teachers via questionnaire survey proving that experiments and field trips are an indispensable component of teaching process and appropriate motivational tools at primary...
