Abstract

This study aims to describe the internal cognitive conflicts that occur to students when they were solving mathematics problems. There were two participants in this research. They were 7th grade students from SMPN 1 Malang. The first participant was a student who has experienced internal cognitive conflicts and has capability to resolve it as well as the mathematics problems. Meanwhile, the second participant was a student who has experienced internal cognitive conflict but cannot resolve that conflict and also the mathematics problems. This research was used descriptive qualitative. The data of this study was gathered from students’ test on cognitive conflict and interview which was adapted from Newman's interview procedure. It was found that, the students who are able to find a relationship between the ratio of the number of workers and the number of chairs produced in a day, have capability to resolve their cognitive conflicts so that it brings them to the right problem solving. Meanwhile, the students that fail to build a relationship between the comparison concepts with mathematics problems and fail to find the relation between the numbers of people with the number of chairs in one day can not resolve the cognitive conflict so that they solve the problems in the wrong ways.

Abstract

The study's purpose is to describe the cognitive conflicts experienced by students with relational understanding when solving the problem of three-term ratios. The current research is a case study with a qualitative approach using a purposeful sampling technique. The three research objects are representations of the condition that (1) the student was sure of his solution (cognitive conflict was solved) and the solution is correct, (2) the student was confident with his solution (cognitive conflict was solved) but the solution is not correct, and he is not confident with the solution (cognitive conflict was not solved), and the solution was not correct. The results of this study describe students with relational understanding experience cognitive conflicts, that is, being aware of the conflict between the initial concepts they have and the results obtained. Students feel doubtful and worried, as indicated by the awareness that the initial scheme applied to one proportion problem cannot be applied to other comparison questions. Students' cognitive conflicts with relational understanding do not always lead them to get the correct solution to the three-term ratio problems. The reason is that the student believes comparison is wrong (misconception).
