Abstract

This study aims to improve the students’ critical thinking skills using time bar media in mathematics learning of Grade IIIA of SD Negeri 1 Kotagede – an elementary school in Yogyakarta, Indonesia. It used classroom action research design by Kemmis and McTaggart. The data were collected through observation, written tests, and interviews. The obtained data were analyzed using descriptive quantitative and qualitative techniques. The results showed that the use of time bar media in mathematics learning could improve students' critical thinking skills. The critical thinking skills covered: (1) providing simple explanations, (2) building basic skills, (3) concluding, (4) providing further explanations, and (5) arranging strategies and tactics. The increase in students' critical thinking skills was seen based on the test results in the pre-action (43%) which increased to 80% in the first cycle and increased to 90% in the second cycle.

Abstract

This study aims to describe, interpret, and analyze the PGSD UPY students’ difficulties in learning mathematics 2. The research type is a descriptive qualitative research. The research subjects are students and a mathematics lecturer of PGSD UPY. The data were gathered through interviews, observations, documentations, and tests. The data validity test was done by using triangulation of sources and techniques. Proprietary interactive analysis models (Miles, Huberman, & Saldana, 2014) were used to analyzed the data. The results show that there are some difficulties experienced by students in learning numberic system especially for fractions. The pretest and post test results show that  A1 and A2 students get low average score on fractions materials. The average score of the pretest for A1 is 66.11 while A2 is 62.35. The average core of the posttest for A1 is 67.22, while A2 is 63.52.
