Digital filters - learning simulation
Hampl, Lukáš ; Pikula, Stanislav (referee) ; Šedivá, Soňa (advisor)
This thesis focuses on the theoretical analysis and application of methods of the two basic types of the digital filters designs. The specific digital filters in this bachelor’s thesis are filters FIR (final impulsive response) and IIR (infinite impulsive response). The main aim in this bachelor’s thesis is, besides the theoretical analysis about the digital filtration, to create a program in the LabVIEW. A user can design digital filters of both types with the help of this program. This program should serve as a learning tool for students to easier understand the problematics of the digital filtration. The emphasis is on the possibility of the design of both filters when user can try how each property is changed with the slightest change of settings. Apart from the filtration of the own input signal, the reciprocal comparison of the both digital filters according to a few criteria is very important.

Interactivity principle in multimedia learning materials in 3rd and 4th grade primary school students
Tetourová, Tereza ; Brom, Cyril (advisor) ; Lukavská, Kateřina (referee)
The aim of this study was to investigate, whether the aspect of interactivity (meaning problem solving interactivity) implemented in multimedia learning materials would positively influence learning outcomes of students. The third and fourth-grade pupils had been split up in two groups and they learned about a topic of natural sciences for about 20 minutes. The first group were studying from an interactive material - short educational game. The second group were studying from a noniteractive material - short educational animation. As variables we have chosen the following - the learning outcomes of the pupils, the amount of motivation to manipulate with the educational tool and the evaluation of atractivity of this tool. Based on multimedia learning theories (CTML, CATLM), we assumed that interactivity would enhance the extent of motivation, evaluation of atractivity and the learning outcomes. Our results partially confirmed our hypothesis. We found positive effect on motivation and evaluation, nevertheless we found no effect on learning outcomes - there was no difference between the groups within this domain. As one of the possible explanations we propose Sweller's cognitive load theory. KEYWORDS Multimedia learning, interactivity, educational animation, educational game, learning outcomes

The use of information scraping for the development of educational simulations
Dobrovolný, Viktor ; Šisler, Vít (advisor) ; Pokorný, Jan (referee)
This bachelor thesis deals with possibilities of the use of web scraping method in the development of educational simulations. Author notes differences between the terms information scraing, web scraping and screen scraping and defines term web scraping, which is used for the remander of the thesis. He introduces history nad context of this method especially in the american background and shows simple example of a web scraper. Examples of the use of web scraping that can be seen on the Internet are described and analyses particular cases of projects that make use of this method. In the end of the first part the thesis deals with complicated juridical situation around web scraping and notes ethical difficulties related to the use of scraping. Author then briefly deals with educational simulations and explores the possibilities of the use of web scraping in thedevelopment and updating of simulations including typical structure of data used in simulations that are suitable to be developed with help of scrapers. In the final part a draft of educational simulation about energetics, which could profit by the use of scrapers both in the process of development and in the process of updating, is introduced.

Educational Simulation in Task Situations (A survey focusing on the aspects of acceptance, interactivity, and authenticity)
Hannemann, Tereza ; Krykorková, Hana (advisor) ; Pinkas, Jaroslav (referee) ; Páchová, Anna (referee)
The dissertation 'Educational Simulation in Task Situations' is focused on a new medium - educational simulation, which is starting to establish itself in the field of education. This work is examining educational simulations from three different points of view: 1) the acceptance of educational simulations in the school environment, 2) the interactivity of learning material, and 3) the authenticity of learning material. The experimental results are divided into three separate chapters according to the respective viewpoint. The investigation focused on acceptance in the first chapter draws from the evaluation of 34 Czech teachers and more than 1000 students, who both evaluated the benefits and shortcomings of particular educational simulations that were used by the teachers and their students. The experiment on interactivity (N = 152) in the second chapter is focused on the experimental comparison of learning material with activated interactive features and learning material with deactivated features. The third experiment on authenticity (N = 48) compares teaching material using authentic media sequences and the same material converted into an animated form. All three main chapters contain a theoretical review of the respective topic and our own experimental research. The methodology is based on the...
