Ball position control with airflow using PLC
Hubálek, Michal ; Němec, Zdeněk (referee) ; Lang, Stanislav (advisor)
This bachelor thesis deals with the design of an educational model of air levitation and regulation. The theoretical part introduces the principle of the programmable logic controller of the company B&R Automation. In the next part, methods of measuring distance were described. The main part of the work was the construction of the whole mechanical part. Furthermore, the design of electronics and cabling to connect the model with a programmable controller. The final output is a functional model of air levitation and a tutorial for the subject.

Construction of laboratory model "Ball on Spool"
Pohludka, Jan ; Appel, Martin (referee) ; Dobossy, Barnabás (advisor)
This thesis is primarily about designing laboratory model Ball on Spool. The first part of this thesis describes modelling of the system, calculation of parameters, design of the control and simulation, based on which the requirements for the actuator are determined. Secondly, this thesis outlines the design of physical model based on simulation results. All of the components used are described, together with the electrical circuit. Parameters of the physical model are estimated using measured data from experiments. The last part is about designing a control of physical model and its demonstration. This thesis also includes a user manual.

Návrh a realizace výukového modelu Závaží na pružině
Mikulenka, Ondřej ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
This thesis deals with the creation of an educational model of a mass on a spring. The model's construction includes a sensor and an actuator for system excitation. A data acquisition card has been developed to control the model. The parameters of the simulation model were determined based on measured data. The work includes demonstrative exercises for teaching purposes. It provides a comprehensive approach to the "Mass on Spring" model.

Design and implementation of a pneumatic educational model
Javorek, David ; Dobossy, Barnabás (referee) ; Najman, Jan (advisor)
The bachelor thesis deals with creating an educational pneumatic model and its subsequent simulation. The research section describes the possibilities and types of control of pneumatic actuators. Furthermore, their modelling in Simulink using Simscape blocks is explained here. In the practical part of the work is given the procedure of creating an educational model, how their control and data collection from sensors is solved. Finally, the modelling of the simulation is explained.

Work with Models in Biology Teaching
Zemanová, Tereza ; Pavlasová, Lenka (advisor) ; Skýbová, Jana (referee)
The main idea and the aim of the Diploma Thesis is to point out the importance of applying models in the teaching natural history, and to prove whether models positively contribute not only to the activation of students, but also to the increase of their cognitive knowledge. The theoretical part of the Diploma Thesis is focused on the student's attitude towards working with models, on the pedagogical and psychological resource for integrate models into teaching and the model themselves. On their classification, properities and didactic function. The second, practical part to the Diploma Thesis presents proposals for specific models that were created and applied during teaching at a secondary school in Týniště nad Orlicí. Diploma Thesis also contains a comparison of the results of students who did not have the opportunity to work with the model and with students who participated in its creation. In addition, the Diploma Thesis includes research of the attitudes of these students towards working with models.

Teaching aids for physics and chemistry created by FFF 3D printing
PÍŠA, Adam
The thesis focuses on the creation of a set of experiments for teaching physics and chemistry using aids created by 3D printing. Each experiment is designed based on the framework curriculum for primary or secondary school. Firstly, experiments using existing aids are created, followed by an experiment with a modified aid, and the largest part of the thesis focuses on experiments with newly created aids. Each experiment is described and commented, including photo documentation, and at the same time the model is shared via the online interface Printables. In total, there are three existing, one modified and eight custom aids in this thesis. All aids have been verified by the author in his own lessons and presented to other teachers of relevant subjects. Based on the verification, it can be stated that the biggest benefit is easy modifiability and low cost.

Comparison of attractiveness of educational models vs. real mounted zoological specimens for secondary chool pupils
Šibravová, Jitka ; Mourek, Jan (advisor) ; Janštová, Vanda (referee)
This thesis deals with the preference of pupils at secondary schools (gymnasia) for different types of teaching aids in zoology education. The main objective was to determine whether the pupils rate educational models as more attractive than the real zoological preserved specimens and whether their preferences are related to their susceptibility to potentially phobic stimuli, realism of the object or whether preferences differ between the sexes. Selected models included entire animals as well as animal organs. The research was conducted at selected secondary schools (gymnasia) in Prague and Jablonec nad Nisou using a questionnaire and a preference test. Secondary school pupils and their biology teachers participated in this research. The realistic design of each object was assessed by researchers and students from the Faculty of Science Charles University using a scale questionnaire. The results showed that students rated the real zoological preserved specimens as more attractive compared to teaching models, with no dependence on whether the objects were entire or anatomical. Effect of gender on overall preference has not been showed; however, the boys had a tendency to evaluate generally unpopular organisms more positively than girls. No influence of susceptibility to potentially phobic stimuli,...
