The subject of this thesis is using CLIL in practice at upper secondary school. The introductory part introduces CLIL generally, it speculates over the meaning, opportunities and difficulties of using it at Czech schools. The practical part contains four units: Taxonomy, Geology, Animals and Genetics, which help teachers link biology with English language using CLIL. The materials benefit from the author's experience with teaching both English language and biology at upper secondary school as well as previous experience with creating teaching materials. The main aim of this thesis is to verify these materials are usable in real educational process and to let students evaluate how well the lessons went through a questionnaire. The verification has proven the materials are usable and students find them beneficial.

Considerando explicações sobre o fenômeno polinização a partir de narrativas biológicas, este estudo foi norteado pela seguinte pergunta: até que ponto alguns termos, aparentemente finalistas, podem ser usados em textos científicos sem que ocorra um prejuízo no entendimento de questões ontogenéticas e filogenéticas? Diante esta questão, os objetivos desta pesquisa foram: i) apresentar uma discussão sobre as explicações funcionais na biologia, especificamente em relação ao fenômeno polinização e ii) contribuir para reflexões epistemológicas no ensino de Biologia. Foram selecionados dois filósofos para definições e análises sobre linguagens funcionais, Larry Wright e Robert Cummins. Para análise dos textos científicos sobre o fenômeno polinização, foi realizado o recorte de dois momentos históricos, um do século XVIII, quando se iniciou os estudos sobre polinização, e outro do século XIX, quando a teoria da evolução estava em discussão. As duas interpretações filosóficas defendem, embora de uma maneira distinta, a existência de uma ideia explanatória do conceito de função para a biologia. A concepção de Larry Wright (1973) sustenta que a função explica por que algo existe e a de Robert Cummins (1975) considera que o poder explicativo da função está na avaliação de sua contribuição para o sistema do qual faz parte, não sendo relevante para sua compreensão a informação sobre sua origem evolutiva. As duas obras científicas primárias selecionadas para análises, de Christian Sprengel (1750-1816) e Charles Darwin (1809-1882), apresentaram alguns termos aparentemente finalistas, ou seja, com conotação de caráter teleológico. A análise dos dados permite dizer que a questão sobre função na biologia é bastante inquietante. Tanto a ciência quanto a filosofia estão em processos de desvelar quais as melhores formas de tratamento de termos finalistas que satisfaçam os problemas de seu uso sem que ocorra um prejuízo no entendimento das questões evolutivas do fenômeno estudado. Este estudo sugere uma redução do uso de termos teleológicos em textos científicos, uma vez que há diferentes visões sobre este conceito, o que pode gerar interpretações incorretas. Além disso, as implicações deste estudo para a Didática da Biologia são apresentadas por meio de inserções filosóficas-epistemológicas em aulas de Biologia com o intuito de permitir o desenvolvimento dos conteúdos biológicos de forma mais reflexiva e contextualizada. / Considering explanations about the phenomenon of pollination from biological narratives, this study was guided by the question: at what extent some terms, supposedly finalists, can be used in scientific texts without losses of ontogenetic and phylogenetic meaning? Therefore, the objectives of this research were: i) to present a discussion around functional explanations in biology, specifically in relation to the phenomenon of pollination; and ii) to contribute to epistemological reflections in Biology education. Two philosophers were selected for definitions and analysis of functional languages, Larry Wright and Robert Cummins. To the analysis of the scientific texts about the phenomenon of pollination, two historical moments were framed, one from the XVIII century, when the studies of pollination started, and another from the XIX century, when the theory of evolution was under discussion. Both philosophical interpretations defend, though in distinct ways, the existence of an explanatory idea of the concept of function to biology. Larry Wrights (1973) conception of function is that it explains why something exists, while Robert Cummins (1975) considers that the explicatory power of the function lies in the evaluation of its contribution to the system it belongs, but the information of its evolution history is not relevant to comprehend the function. Both primary scientific works selected for analysis, from Christian Sprengel (1750-1816) and Charles Darwin (1809-1882), presented some terms apparently finalists, which means, with teleological connotative character. The data analysis allowed saying that the inquiry about function in biology is quite intriguing. Science and philosophy are in process of unveiling the best approaches to finalist terms that would satisfy their usage problems without comprehension losses of the evolutive processes of the studied phenomenon. This study suggests a reduction of the use of teleological terms in scientific texts, since there are different analyses about the concept that may lead to misinterpretation. Moreover, the implications of this study to the Didactics of Biology are presented by means of philosophycal-epistemological inserts in Biology classes in order to enable the development of the biological contents in a more flexible and contextualized way.

This thesis proposes a possibility of using the exposition of primates in the Prague zoo during the school excursion for pupils of the 7th or 8th grade of elementary school. The thesis is divided into individual parts that theoretically analyse the importance of excursions for education and subsequently it is practically focused on facilitating the smooth course of the excursion and other activities that precede the excursion or follow it freely. In the thesis there is the general sorting of primates into individual species described in detail and there is provided basic information about primates that are bred in the Prague zoo. Further, possible excursion trail including individual expositions where the particular animals can be seen is described in detail. The main objective was to provide teachers with detailed instructions on how to make the excursion so it is successful. The purpose of the work was also to create materials which help to actively memorize the information provided and to raise children's interest in such an interesting animal species as the primates. With regard to the fact that most primates are currently threatened by extinction in their natural habitat, the theme of the excursion is closely linked to environmental issues and a responsible approach to the use of natural...

The Diploma thesis deals with the CLIL (Content and Language Integrated Learning) educational method integrating the fields of human biology and Russian language. The goal of the thesis is to prepare lectures and study materials, its testing and verifying its efficiency in teaching process on two groups of subjects - two grammar school classes (students at the age of 18-19). The input level of knowledge was tested on both classes through the pretesting. The first group of students was afterwards taught with "soft" CLIL method (the theory explained in native language), the second group with "hard" CLIL. The questionnaire showed neutral attitude of the students towards the CLIL method with rather more positive approach from the females compared to the male students. The posttests followed, showing only a marginal difference between input and output level of knowledge on both groups. KEYWORDS CLIL, Human biology, Teaching of biology, Didactics of Biology

This thesis deals with the issue of working with text in biology lessons at primary schools. The aim of this work is to determine the ability of pupils to analyze text materials and to work with them in different ways. In the research part of the thesis were created texts for teaching pupils at the 2nd level of primary school and the following 8 tasks. Tasks were given to pupils (n=75) in grades 6, 7 and 8 at different stages of the lessons. The tasks were subsequently evaluated and the student's ability to solve the problem was assessed on the basis of the results. In six assignments, pupils had a higher success rate then 70%, while only two had less than 45%. Research results have shown that the ability of pupils to understand and work with text is good. It has also been found out which methods are amiss and how to adjust the tasks. Key words Work with text, teaching of biology, didactics of biology, teaching methods

The diploma thesis deals with the comparison of two selected concepts of science teaching at primary school. The theoretical part of the thesis summarizes the classification of science as an educational field, explains the possible concepts of its teaching and compares the advantages and disadvantages of two selected variants with reference to the fulfilment of educational goals and respect for didactic principles of science teaching. The available materials suitable for teaching, the degree of their use and the comparison of teaching methods depending on the success in scientific testing are also outlined. The practical part of the work brings a comparison of the results of a questionnaire survey between individual groups of ecologically and science-taught pupils. Individual tasks and questions were created on the basis of established hypotheses. The results of the research bring a comparison of the knowledge and skills area, but also the area of students' attitude towards the subject. The established hypothesis was confirmed partially, the attitude section brings in results to the research questions. Students taught ecologically were indeed more successful in the task that led to the connection of knowledge and derivation from the relationships between organisms, but the differetence were not...
