Abstract

This study aims to reveal thinking profile and problem solving ability of mathematics department students of Universitas PGRI Semarang in solving plane problem by providing scaffolding. Type of this study is a qualitative research. The selection of research subject is based on students’ ability, feedback from lecturers and fluency both in oral or writing. Data collection technique used is Think Aloud Method. The results of the study provide an overview that after being given scaffolding, students with intermediate level of mathematics have characteristics: using the assimilation thinking process in understanding the problem, using assimilation and accommodation in planning to solve the problem. The students with lower level  of mathematics, they use assimilation thinking process in understanding the problems and planning the settlement whereas they are not able to use accommodation thinking process.  Students’ inability in accommodation thinking process causes they can not make solution planning correctly, solve the given problems and checking the solutions. The study shows the students experienced a lot of thinking process development since they have been able to use all of information for solving the problems. The number of the given scaffolding depends on individuals and the level of students’ tinking ability.

Abstract

The ability of problem posing is very essential for the student?s. However, there are still many students who don't realize the importance of these abilities. This research describes the senior high school student?s ability in mathematical problem posing, especially in the material system of linear equations in three variables. Research data were collected from 7 student?s using written test and interview techniques. The validity of the data used triangulation methods by comparing the results of written tests and interviews. Data were coded, simplified, presented, and triangulated for the credibility and conclusion drawing. The results show that there were still very few students who have all three classifications of problem posing abilities, namely pre-solution posing, within-solution posing, and post-solution posing. Students who have the ability of pre-solution posing can ask questions based on the data provided and can arrange problem solving. Students who have the ability of within-solution posing can write what is given and asked of the problem, raise supporting questions which is relevant to the problem and arrange solutions to the supporting questions and problems that are given correctly. Students who have the ability of post-solution posing can raise similar mathematics problem after solving the problem. Students can also arrange solutions to problems that have been made. Teacher needs to practice pre-solution posing, within-solution posing, and post-solution posing to the students.
