1 ABSTRACT The current chemistry education solves problems related primarily to the setting of the curriculum contents, which would be professionally correct, appropriately extensive, and at the same time connected with current aspects of life in modern society, and to problems of teaching strategies that would stimulate the students into an interest in science and commitment to it. The main goal of this dissertation is to create an educational website with an interactive chemistry course for lower secondary schools (ISCED 2) and verify its effectiveness in school practice. The first part of the dissertation describes methods of interactive chemistry teaching supporting the increase of the students' cognitive activity and the effectiveness of the learning process using ICT. The second part characterizes the chemistry course thus created and lists various ways to apply interactive teaching in it. Our interactive course contains a total of 14 thematic units, each with 2-6 subthemes. All themes are processed with respect to the practical application of the subject matter using the listed interactive education methods. This course was tested in 2018-2020 during chemistry lessons in Kazakhstan and Czech Republic, and the students' opinions toward interactive teaching in this study were tested using a simple...

The diploma thesis evaluates the impact of the crisis caused by covid-19 on construction companies, especially through a questionnaire survey and interviews with representatives of construction companies.

Despite widespread use of web-based e-learning applications, insufficient attention is paid to their usability. There is a need to conduct evaluation using one or more of the various usability evaluation methods. Given that heuristic evaluation is known to be easy to use and cost effective, this study investigates the extent to which it can identify usability problems in a web-based e-learning application at a tertiary institution. In a comparative case study, heuristic evaluation by experts and survey evaluation among end users (learners) are conducted and the results of the two compared. Following literature studies in e-learning - particularly web-based learning - and usability, the researcher generates an extensive set of criteria/heuristics and uses it in the two evaluations. The object of evaluation is a website for a 3rd year Information Systems course. The findings indicate a high correspondence between the results of the two evaluations, demonstrating that heuristic evaluation is an appropriate, effective and sufficient usability evaluation method, as well as relatively easy to conduct. It identified a high percentage of usability problems. / Computing / M.Sc. (Information Systems)

The use of interactive e-learning tutorials is an effective form of teaching and learning. It is therefore important that attention is paid to their usability. This research relates to the evaluation of a CD-based e-learning tutorial for learning Business English, with the aims of investigating its usability and identifying problems. Particular attention is paid to aspects that hinder the learner from achieving the learning objectives. The study uses two usability evaluation methods (UEMs), namely controlled usability testing in an HCI laboratory and a user questionnaire survey. The main aim of the study is to compare the findings and determine the impact of using two methods in combination. The first outcome of the research was a synthesized framework of evaluation criteria that was applied in the two UEMs. Secondly, findings of the evaluations indicated that two UEMs identified similar problems, thus confirming their reliability in usability evaluation. Another finding was instances where one method produced results not obtained by the other, which shows the complementary value of two different UEMs. A third benefit of the study was that it identified usability problems in the target system. / Information Systems / MA (Information Systems)

Analysis of knowledge level in common local vertebrate species at children from different school types and hobby groups This thesis deals with the research of practical knowledge and skills of students of primary and secondary schools. It targets exploring of cognition of local common species of vertebrates (fish, amphibians, reptiles, birds and mammals). It takes up this research (Lang, Pravda, 1971). It takes a large part of their methodology and compares the results with selec- ted reference species. The results are presented in graphs and chart tables. Key words: Knowledge of local vertebrates, questionnaire survey, primary school, secondary school, high school, hobby group, genus name, species name.

The main purpose of the diploma thesis is to determine the willingness of people visiting the Eastern Slovak dam Ružín to pay for improving water quality, namely for the environmental good. Willingness to pay is determined by questionnaire investigation the contingent valuation method. Dam is a public good, which has no owner. We all use it without someone to care for it. This use is not positive, but negative in terms of pollution, clogging of toxic sediments. The theoretical part is devoted to construction and the need to build dam as well as environmental problems, which occur at the dam. This is related to the problem of public good and "the tragedy of the commons." There are the contingent valuation method and development of the questionnaire described at the end of theoretical part. The practical part consists of the evaluation questionnaire investigation and the linear regression model in terms of the parameters under which they were created identifiers variables and point estimates. Finally, it is converted by statistical analysis of the impact of variables on the amount that people are willing to pay.

Cette thèse se propose d’étudier « l’enseignement et la diffusion du français en Afghanistan : bilan et perspective ». L’enseignement du français s’est développé depuis presque un siècle en Afghanistan. La langue française est enseignée au niveau secondaire, au niveau universitaire, à l’Institut français d’Afghanistan ainsi qu’aux centres privés en Afghanistan. Le présent travail a tenté très modestement de montrer quelles sont les démarches mises en œuvre pour l’enseignement et la diffusion de français en Afghanistan. Tout au long de ce travail, nous nous sommes fixées comme but fondamental d’explorer la situation d’enseignement/apprentissage du français, sa situation, les motivations des étudiants afghans pour l’apprentissage de cette langue, les représentations qu’ont ces étudiants de cette langue ainsi que les soutiens et les dispositifs mises en place pour l’enseignement, la promotion et la diffusion de cette langue en Afghanistan. La méthodologie de ce travail est basée sur des enquêtes menées à Kaboul (entretiens semi-directifs et questionnaires). Nos enquêtes ont été réalisées à l’aide des données recueillies par l’intermédiaire de deux outils de données : des enquêtes par questionnaires réalisées auprès des enseignants et d’apprenants (les élèves et les étudiants) du français et un entretien semi-directif auprès des professeurs du département de français de l’Université de Kaboul. Nos échantillons sont constitués par les étudiants du département de français (les étudiants spécialistes du français), les étudiants hors-département (les étudiants non-spécialistes du français), et les élèves des deux lycées francophones afghans (lycées Istiqlal et Malalaï), ainsi que par les enseignants de ces institutions : département de français et lycées Istiqlal et Malalaï. D’après le résultat de ces enquêtes, les étudiants afghans apprennent le français pour plusieurs raisons : instrumentales et personnelles. Le français est considéré comme une langue importante du point de vue professionnel d’une part et d’autre part, c’est la valeur culturelle et le prestige de cette langue qui donnent la possibilité aux Afghans d’accéder à une culture riche. Il est également perçu, d’après ces étudiants, comme une langue d’ouverture sur le monde, c’est pourquoi le français possède d’un statut privilégié en Afghanistan. Bien que les Afghans n’utilisent pas le français pour écrire, parler et pour la communication quotidienne et professionnelle, la persistance de cette langue est due aux raisons positives et les représentations qu’ont ces étudiants de cette langue. / This thesis proposes to study the "teaching and diffusion of French language in Afghanistan: review and perspective". The teaching of French has been developed for almost a century in Afghanistan; the French language is taught at the secondary level, at the university level, in the French Institute of Afghanistan as well as at in the private centers in Afghanistan. The present research has tried very modestly to show what are the approaches implemented for the teaching and the diffusion of French in Afghanistan. Throughout this work, we have set ourselves the fundamental goal of exploring the teaching and learning situation of French, the motivations of Afghan students for learning this language, the representations these students have of this language as well as the supports put in place for the teaching, the promotion and the diffusion of this language in Afghanistan. The methodology of this work is based on surveys conducted in Kabul (semi-structured interviews and questionnaires). Our surveys were conducted using data collected through two data tools: questionnaire surveys of teachers and students of French and a semi-structured interview with professors of the French Department of Kabul University. Our interviewees are made up of students from the French department (students specializing in French), students learning French as second language, and students from two French-speaking Afghan high schools (Istiqlal and Malalaï), and the French teachers of these institutions: Department of French and Istiqlal and Malalaï high schools. According to the results of these surveys, Afghan students learn French for several reasons: instrumental and personal. French is considered an important language from a professional point of view on the one hand, and on the other hand, it is the cultural value and prestige of this language that gives Afghans access to a rich culture. It is also perceived, according to these students, as a language of openness to the world, which is why French has a privileged status in Afghanistan. Although Afghans do not use French for writing, speaking and for daily and professional communication, the persistence of this language in afghan society is due to the positive reasons and the representations that these students have of this language.
