Title: Pupil's personality and solving problems of school Mathematics by heuristic strategies Author: Mgr. Markéta Škutová Supervisor: prof. RNDr. Jarmila Novotná, CSc This thesis deals with the relationship between the type of pupil's personality in the dimension of information reception and their ways of solving problems of school Mathematics with the use of heuristic strategies at the lower secondary education of basic school and in the corresponding years of grammar schools. The theoretical part summarizes the knowledge of heuristic strategies in the teaching of mathematics at the lower secondary education of basic school and their application on examples. Furthermore, the theoretical basis of type theory and its use in education is explained. In the practical part the results of the typological questionnaire are presented and an extensive qualitative analysis of the student's problem solving is offered. The resulting findings are supported by concrete examples of students' solutions. In this diploma thesis, there is evidence that the intuitive pupils use the heuristic strategies of problem solving more often than the sensory pupils and are more successful in solving non-traditional tasks. Keywords: heuristic strategies, MBTI, type theory, problem solving

This work is a reflection on the results of an experimentation carried out on secondary school students of between 16 and 18 from various classes. The experimentation aims at identifying the implicit ideas they use when asked to solve a certain mathematical problem. In particular, in giving them these problems an heuristic approach was suggested, and the differences between this and a purely deductive approach were measured. Analyzing the different approaches used by the students and the difficulties they had in distinguishing between argumentative and demonstrative operations has given rise to a reflection on the use of software such as Geogebra and Excel.

This master's thesis deals with unusual applications tasks and problem tasks in teaching mathematics at the upper primary school as well as with their solving strategies. The whole work is build around an analysis of pupils' solutions of selected problem tasks. It was found that solving the tasks caused considerable troubles to a significant part of the pupils. The final part of the thesis contains a collection of problem tasks along with their solutions that is focused on teaching heuristic problem solving strategies and based on the analysis results.
