 ADAMCOVÁ, Hana
This diploma thesis deals with a topic of mathematics, namely word problems with fractions and percentages. Specifically, this work deals with students' solutions to such word problems. The work acquaints the reader with how selected word problems with fractions and percentages are solved by pupils in the 9th grade of primary schools. It introduces the readers to the various numerical procedures chosen by the students. Some procedures occurred more frequently, others only rarely. Each word problem is supplemented by a graph, which shows the success of students in solving the word problem. The work also includes photographs of students' solutions for the reader's better idea. At the end of the chapter, some word problems are processed using the Concept Cartoons method. The work shows mainly close connections between fractions and percentages.

The solving of ecology tasks by students of primary school
 ČÍŽKOVÁ, Lenka
This thesis describes the primary school pupils' solution of ecology problems. The focus is the ecosystem of artificial lake. 63 pupils of the 5th grade of 3 elementary schools were given 11 problems on this topic. Assignment and solution was done via online forms due to the elementary schools being closed at the time of research. There were both open and closed problems in the questionnaire, the majority of the were assigned in the form of concept cartoons. The thesis studies the way the pupils solved these problems with the emphasis on the method rather than on the correctness of the solution (but the correctness is evaluated as well). The thesis presents the used method of numerical and graphical evaluation and points on some of the aspects of the pupils' solution. Among these aspects are: influence of the assignment layout, time necessary to solve the problem or the pupils' capability to form and write their own answer using a PC form.
