Students' procedures for mathematical word problems solvable by systems of equations during the school leaving examination
 Doubrava, Jiří ; Chvál, Martin (advisor) ; Vondrová, Naďa (referee)
This diploma thesis investigates different approaches to solving word problems with systems of equations. The thesis aims to discover which strategies are used by senior students when solving these word problems and documents the processes involved. The research presented in the thesis is based on an in-depth analysis of the database of student cut-outs from five word problems of the common part of the Maturita exam, specifically from the spring terms between the years 2016 and 2020. The theoretical part involves an analysis of three textbooks for high school students in the Czech Republic which incorporate the named phenomena. Furthermore, this part includes a list of student strategies for solving word problems, moreover, the reader is provided with a description of the state Maturita exam in Mathematics. The empirical part contains an overview of several possible procedures prepared during an a priori analysis. It also presents psychometric features of the chosen word problems by incorporating statistical outcomes. In addition, cut-outs of students' answers are divided into various groups based on the chosen solving strategies, thus demonstrating the possible techniques used by the students when solving this type of tasks. The principal conclusions demonstrate immense omissions, supporting the...

The Influence of the Attractiveness of Context of a Mathematical Word Problem on Performance and Solving Processes
 Havlíčková, Radka ; Jirotková, Darina (advisor) ; Novotná, Jarmila (referee) ; Hošpesová, Alena (referee)
This thesis focuses on to word problems and elementary school pupils. Research on mathematical word problems suggests that differences in success are not only due to different levels of pupils' cognitive abilities but that their motivation plays a role, too. Therefore, in this study, I focused on the context of word problem as a potential source of situational interest, which may affect the quality of pupils' cognitive function in the short term or permanently. I used my participation in a broader quantitatively oriented research on variables influencing the difficulty of word problems and using its methodology, I investigated the influence of different types of contexts on pupils' success in solving the problems. The examined aspect of context was attractiveness - the question was whether pupils would be more successful in solving word problems with elements of fairy tale, science fiction or humour than in similar problems with the same structure but with a neutral context. Pupils of the 3rd to 6th grades of primary school (n = 2 092) were divided into two groups of a comparable ability and each was presented with one of the variants - attractive or neutral. To evaluate the results quantitatively, the Item Response Theory was used allowed us to determine the difficulty of the problem depending on...
