The position of the chemical experiment at the time of ICT - aluminum and its compounds
Sloup, Radovan
The main goal of the thesis is to describe a position of the real experiment in chemistry at the beginning of the 21st century and to contribute to solution of speculations if this didactic tool is or is not at current schools such a rarity as it's often described. The starting point of the thesis is extensive research of the literature related to history of natural science literacy which is condition not only for the right experiment interpretation but also of its suitable usage in the lessons. The theoretical part observes also the ensuring of the chemical experiment in the curricular documents and its position in the chemistry teaching in recent past. The experiment is a dynamic visualia therefore the visualias are classified in particular part of the thesis and their occurrence and function are described - in today's information society, chemistry textbooks, as a part of hypermedia programs for chemistry teaching and in lessons in general. The thesis focuses partly on hypermedia programs, especially then on materials for chemistry teaching that proved to be helpful in e-learning. Through the questionnaire inquiry at primary and secondary schools in Czech Republic were discovered not merely material also personal options of the schools and chemistry teachers in relation to the experiment...

Multicomponent learning tasks in chemistry
Trčková, Kateřina
The main goal of this dissertation was to create and verify own multicomponent tasks of interdisciplinary character based on analysis of types of tasks occured in international research. Newly created multicomponent learning tasks were classified by task type, solution form, cognitive demands and task variety. Tasks of the same form were ordered to pairs, their difficultness, vulnerability and rate of success were verified. Multicomponent learning tasks were assigned verbally or nonverbally (charts, tables or pictures). Closed jobs (ordering items, matching items, multiple choice questions, true/false questions) and open jobs (wide-answer items, short-answer items) were used in complex of tasks. Rate of success of individual tasks was processed by non-parmetric statistical Wilcoxon test based on form, gender and type of study. Research survey was complemented by pupils' self- reflection questionnaires and teachers'questionnaires about testing process. Key words Multicomponent learning task, taxonomy of learning task, scientific literacy, reading literacy, self-reflective questionnaire.

Elaboration of Learning Problem-Tasks from the Field of Chemistry
Vojíř, Karel
This thesis deals with the elaboration of learning problem-tasks related to the Standards for elementary education in the field of Chemistry. The author of this thesis worked on this topic within a project under National Institute for Education. The starting point for creating the tasks, illustrating and concretely expounding the Standards is the concept of science literacy. In this principle in chemistry instruction a broader context and a transfer to everyday life are applied. Learning tasks were created on the base of: science literacy and the results of Czech pupils in its testing, context of standards in Czech curricular system, elements of problem-based learning, types of learning tasks and cognitive parameters. During the elaboration of the tasks a pilot testing of selected learning tasks was realized. The results of the pilot testing were used in further designing more problem-tasks to cover one expected outcome in every topic of Chemistry within the elementary school curriculum. According to the methodology described in this thesis, a material named Methodical comments and tasks to the standards for primary education - Chemistry was created. This material contains a coherent set of learning problem-tasks illustrating two- thirds of the indicators from the standards for elementary education...

Out-of-Classroom Chemistry Essentials Education as a Mean of Scientific Literacy Development
Čábelová, Simona ; Rusek, Martin (advisor) ; Bílek, Martin (referee)
This thesis deals with the aspect of outdoor education of chemistry in the context of the natural science literacy concept. This concept is approximated here in association with the curricula documents for secondary education level and the Contextual model of learning. Based on the description of individual contexts of the aforementioned model, an alternative variant of an excursion to the Prague Waterworks Museum in Podolí is proposed. The practical part focuses on the comparison of the efficiency of the "classic" conception of a museum excursion and the alternative approach mentioned previously. The whole concept adheres to the pedagogical experimental scheme. The comparison is achieved through three testings in two groups. The first, control group, had a standard excursion led by a museum guide. The second, experimental group, had an excursion led in the proposed alternative approach. Based on the first tests - the pretests, the starting knowledge of the pupils is analyzed. The second testing is executed as posttests right after finishing each excursion. The third testing is a retention test one month after the excursion. Test results were analyzed using statistical methods. The results of the analysis point to the considerable importance of the way the excursion is led and to the great benefit of...

Scientific literacy and its development by using learning tasks in Chemistry for ISCED 2 level
Distler, Petr ; Teplý, Pavel (advisor) ; Klečková, Marta (referee) ; Čtrnáctová, Hana (referee)
The objective of the dissertation was to assess the suitability of the scientific literacy development by using learning tasks in chemistry classes for ISCED 2. By comparing the learning tasks types in commercial workbooks and in the international assessment PISA, a significant difference in their structure was found out. Although the Czech Republic has undertaken to participate in the PISA project, Czech teachers have a different type of teaching tasks commonly available in their workbooks than the pupils afterwards solve in the PISA project. PISA's released and author's learning tasks were compiled into authentic workbooks. They were used in chemistry classes during the school year 2016/2017. Based on the pupils' results in the final assignments, all groups of grammar school pupils from experimental groups achieved better results in solving multicomponent learning tasks than the control group. However, the results of elementary schools pupils were significantly worse at final test scores than at initial ones, which was explained by the entire loss of their motivation to study. Pupils rated motivation to work with multicomponent tasks above average. They were fully aware of the importance and usefulness of solving multicomponent learning tasks, and, therefore, they solved them with proper...

Preparation of new didactic materials to support science education at the preschool and primary level
Andrlová, Dominika ; Teplá, Milada (advisor) ; Hybelbauerová, Simona (referee)
The diploma thesis is focused on the development of natural science literacy of pre-school age children and pupils of younger school age. The aim of this thesis is didactic processing of materials which will enable teachers/lecturers/parents to develop natural science literacy of children, without themselves having to have education in chemistry for correct understanding of the experiment, and thanks to which, at the same time, they could pass on the correct information to children in such way that prevents from the occurrence of natural science misconceptions to a maximum possible extent. The theoretical part of the thesis is devoted to child ontogenesis in pre-school and early school age, which is subsequently reflected in the creation of materials for development of natural science literacy of this target age category of children. The theoretical work includes also the characterisation of the term natural science literacy as a possible tool for increasing interest in the study of natural sciences. It states the expected positives, but also possible negatives, especially in the form of resulting misconceptions which can be associated to the introduction of natural science education for younger children. In the subsequent part, an analysis of syllabus of natural science-focused subjects at...
