The contribution investigates opportunities that an educational tool called Concept Cartoons can offer in future teachers' education, namely in comparison with word problems in standard written tests. The referred empirical study was conducted in two separated consecutive stages, with two groups of future primary school teachers (the first one from the Czech Republic, and the second one from Slovakia). The participants of the first stage solved four word problems (T1, T2, T3, T4) with increasing difficulty within the written test, and a problem with a similar structure and difficulty as T3 but in the Concept Cartoon form. The second stage of the study served as a complementary stage, its participants solved only the word problem T3 and the Concept Cartoon. In both stages, the comparison of results and solution procedures revealed many participants who mastered the word problem(s) but displayed a fundamental misconception when working with the Concept Cartoon. Two thirds of the participants presented non-corresponding responses to these two corresponding tasks: they solved one of them correctly and the other one incorrectly. All of the problems in the study were based on the part-whole interpretation of fractions, the revealed misconception consisted of incorrect determination of the whole.

With the increase in the number of university students, the number of those who do not finish successfully the tertiary education is also increasing. The article uses a specific data source and analyses only a part of the group of unsuccessful students who re-enroll. This is a specific group of students - they did not finish the tertiary study in the past, but after some time they returned to education. The aim of the paper is to find significant factors that influence the decision whether the student changes the studied school or field of study. Factors will be searched using decision trees and binary logistic regression. Both methods were significant for gender and the fact that a student is studying his preferred university. Logistic regression adds to the student's health disadvantage. The data were obtained from the EUROSTUDENT survey, which was held in the Czech Republic in 2016 under the auspices of the Ministry of Education, Youth and Sports. The results can be used to identify a risky candidate or student at the beginning of tertiary education.
