Design and preparation of database of chemistry experiments for chemistry education
Vrzáčková, Eva ; Šmejkal, Petr (advisor) ; Hájková, Zdeňka (referee)
This bachelor thesis involved the design and creation of a Database of chemical experiments, which serves as a source of demonstration experiments. Videos to individual experiments were delivered using external links. These individual experiments were chosen using criteria from teachers obtained via a general survey. The main criteria were time and material factors, availability of chemicals and also clearness of experiments. A template was made for each experiment, including all the information required. Experiments, for which no suitable video was found, were carried out and recorded. The resulting database includes 58 experiments divided into 25 main categories. Some videos are included in more than one category. The database was then placed on the website www.studiumchemie.cz, the web portal of Charles University Faculty of Natural Science for secondary school Chemistry teaching support.

Video-database of Chemical Experiments - formation and evaluation
Vrzáčková, Eva ; Šmejkal, Petr (advisor) ; Teplý, Pavel (referee)
For many reasons, Chemistry is not among the most popular subjects at Secondary schools. Many students find this subject challenging and difficult to understand. Experiments in Chemistry mainly drive the students' motivation for the subject. Unfortunately, they are often missing during Chemistry lessons, due to high demands on preparation time as well as safety hazards or a lack of chemicals required. Although a real experiment is difficult to replace, a video experiment might be a useful and sufficient alternative when lacking preparation time or the required chemicals, or in case of experiments with safety risks. This thesis therefore focuses on building a video experiment database by extending and improving the basic Chemistry Experiment Database located on the website www.studiumchemie.cz. This is a website administrated by the Faculty of Science of Charles University in Prague, serving as support for Secondary school Chemistry teachers. The database itself was created as a part of my bachelor thesis. The database was now extended and many improvements were made, following the results of a survey among Chemistry teachers, who asked for more experiments in Organic Chemistry and Biochemistry. 96 new experiments were added, with regard to the teachers' suggestions. Currently the database contains...
