Abstract

This study is descriptive research that aims to describe students' collaborative problem solving (CPS) skills in solving mathematics problems. The subjects in this study were 6 students at grade XI consisting of 2 students with high mathematical abilities, 2 students with moderate mathematical abilities, and 2 students with low mathematical abilities. The six of them were divided into 3 groups consisting of 2 students with different mathematical abilities. The three groups were given mathematics problems to be solved collaboratively. The results of this study were analyzed using the semiotic Peirce model approach which uses a trichotomous relationship between representamen (Z), interpretant (I), and object (O) to show the CPS process that occurs. The results of the study show that students' CPS skills vary. The CPS process of high and moderate mathematical ability students is running quite well. Meanwhile, the CPS process of high and low mathematical ability students and moderate and low mathematical ability students was not as good as expected because of the little interaction or discussion between the members of the group in solving problems

Abstract

This study aims to investigate mathematics teacher educators’ (MTE) knowledge in noticing preservice teachers’ pedagogical content knowledge (PCK) on the hierarchical classification of the quadrilateral. A multiple case study was conducted to analyze the responses of ten MTEs in an online moderated-forum group discussion (M-FGD) from their written work on the MTE-PCK test completed prior to the M-FGD. The PCK test consisted of two tasks: the task that examines MTEs’ knowledge to predict pre-service teachers’ reason in representing the hierarchical classification of quadrilateral in Venn diagrams, and the task that examines MTEs’ knowledge in making a flowchart as a recommendation to mathematics teacher to analyze the validity of quadrilateral classification. Results show that the MTEs indicate two considerations of noticing pre-service teachers’ PCK on the quadrilateral classification: by definition and properties of quadrilaterals and by the visual appearance of quadrilaterals. Despite this, 20% of them were indicated to perform a lack of understanding of the hierarchical classification of quadrilaterals, as indicated by invalid flowcharts of validating the hierarchical classification of the quadrilateral.
