Creation of motivation materials for teaching of some themes of chemistry
Langerová, Veronika ; Šmejkal, Petr (advisor) ; Nováková, Lucie (referee)
The diploma thesis deals with the design and preparation of a new educational material focused on the theme of "Quantities and calculations in chemistry" as expressed in RVP-G (Framework educational programme for secondary general education). The form of the presentation of the educational material was designed in context of motivation of students. Hence, the specific presentation was chosen - the website supplemented with pictures, videos and flash animations. As the connecting component and motivation element, the magician Chemulín solving chemical and other related (common life) problems of citizens of fairytale village was chosen. The main goal of this approach is better motivation of students to learn and process information. The thesis also include the circumscription of concepts of the theme "Quantities and calculations in chemistry" as specified by the RVP-G and other curricular documents in the Czech Republic. With due regard for these documents, the qualitative evaluation of the selected educational materials both in the Czech and English languages related to the mentioned theme was accomplished.
